About Pro-Pharmaceuticals, Inc.

We are a development-stage company engaged in the discovery, development, and commercialization of first-in-class, targeted therapeutic compounds for advanced treatment of cancer, liver, microbial and inflammatory diseases. Our initial focus is the development of a new generation of anti-cancer treatments using carbohydrate polymers to increase survival and improve the quality of life for cancer patients. DAVANAT®, our lead pipeline candidate, is a new, proprietary chemical entity that is currently in Phase II trials for first-line treatment of colorectal and biliary cancer.

Our proprietary technologies are target therapies that can also be used to treat other serious diseases such as liver and kidney fibrosis. We entered into research collaborations with the Mount Sinai School of Medicine to study the anti-fibrotic effects of our novel carbohydrate compounds on liver fibrosis and with Brigham and Women’s Hospital to evaluate the anti-fibrotic effects of these compounds to treat acute and chronic kidney disease. Our first-in-class, novel carbohydrate compounds significantly reduced collagen expression and reversed fibrosis in animal models. Whereas previously, in vitro data indicated a reversal of fibrosis markers, in this proof-of-concept animal study, the compounds clearly reduced collagen expression and reversed liver fibrosis. All of our products are in the development stage.

RISK FACTORS THAT MAY AFFECT FUTURE RESULTS

An investment in our common stock involves a high degree of risk. You should carefully consider the risks described below and the other information before deciding to invest in our common stock. The risks described below are not the only ones facing our company. Additional risks not presently known to us or that we currently consider immaterial may also adversely affect our business. We have attempted to identify below the major factors that could cause differences between actual and planned or expected results, but we cannot assure you that we have identified all of those factors.

If any of the following risks actually happen, our business, financial condition and operating results could be materially adversely affected. In this case, the trading price of our common stock could decline, and you could lose all or part of your investment.

Risks Related to Our Company

We are at an early stage of development and have not generated any revenue. We are a development-stage company with a limited operating history, and we have not generated any revenues to date. We have no therapeutic products available for sale, and none are expected to be commercially available for several years, if at all. We may never generate revenue or become profitable, even if we are able to commercialize any products.

We have incurred net losses to date and must raise additional capital in 2008. We have incurred net losses in each year of operation. Our accumulated deficit as of December 31, 2007 was approximately $35.2 million. We will need to continue to conduct significant research, development, testing and regulatory compliance activities that, together with projected general and administrative expenses, we expect will result in substantial operating losses for the next several years. Accordingly, we do not expect to be generating sales or other revenue and will remain dependent on outside sources of financing during that time. If we are unable to raise funds from outside sources for our continuing operations, we may be adversely affected.

We may raise additional capital through equity financings, partnerships, debt financings, bank borrowings, or other sources. Additional funding may not be available on favorable terms or at all. If adequate funds are not otherwise available, we may need to significantly curtail operations. To obtain additional funding, we may need to enter into arrangements that require us to relinquish rights to certain technologies, products and/or potential markets. To the extent that additional capital is raised through the sale of equity, or securities convertible into equity, our equity holders may experience dilution of their proportionate ownership of the company.

Based on approximately $1.3 million of available cash and cash equivalents as of December 31, 2007 and net proceeds of approximately $3.4 million from our public offering completed on February 25, 2008, we believe that we have sufficient capital to fund our operations into October 2008. We must raise additional capital before October 2008 or we may not be able to continue operations.

Our drug candidates are based on novel unproven technologies. Our product candidates are based on novel unproven technologies using proprietary carbohydrate compounds in combination with drugs approved by the U.S. Food and Drug Administration, or FDA, currently used in the treatment of cancer and other diseases. Carbohydrates are difficult to synthesize, and we may not be able to synthesize carbohydrates that would be usable as target delivery vehicles for the anti-cancer drugs we are working with or other therapeutics we plan to develop.

Our drug candidates are in pre-clinical or clinical trials and results are uncertain. We have one product candidate in human clinical trials. Pre-clinical results in animal studies are not necessarily predictive of outcomes in human clinical trials. Clinical trials are expensive, time-consuming and may not be successful. They involve the testing of potential therapeutic agents, or effective treatments, in humans, typically in three phases, to determine the safety and efficacy of the product candidates necessary for an approved drug. Many products in human clinical trials fail to demonstrate the desired safety and efficacy characteristics. Even if our products progress successfully through initial human testing, they may fail in later stages of development. We may engage others to conduct our clinical trials, including clinical research organizations and, possibly, government-sponsored agencies. These trials may not start or be completed as we forecast, or may be unsuccessful.

Our product candidates may not be successfully commercialized. Even if our product candidates are successful in clinical trials, they may not be successfully commercialized. Potential products may fail to receive necessary regulatory approvals, be difficult to manufacture on a large scale, be uneconomical to produce, fail to achieve market acceptance, or be precluded from commercialization by proprietary rights of third parties.

Table of Contents

Our lack of operating experience may cause us difficulty in managing our growth. We have limited experience in manufacturing or procuring products in commercial quantities, conducting other later-stage phases of the regulatory approval process, selling pharmaceutical products, or negotiating, establishing and maintaining strategic relationships. Any growth of our company will require us to expand our management and our operational and financial systems and controls. If we are unable to do so, our business and financial condition would be materially harmed. If rapid growth occurs, it may strain our operational, managerial and financial resources.

We will depend on third parties to manufacture and market our products. We do not have, and do not now intend to develop, facilities for the manufacture of any of our products for clinical or commercial production. Accordingly, we will need to develop relationships with manufacturers and enter into collaborative arrangements with licensees or have others manufacture our products on a contract basis. We expect to depend on these collaborators to supply us with products manufactured in compliance with standards imposed by the FDA and foreign regulators.

In addition, we have limited experience in marketing, sales or distribution, and we do not intend to develop a sales and marketing infrastructure to commercialize our pharmaceutical products. If we develop commercial products, we will need to rely on licensees, collaborators, joint venture partners or independent distributors to market and sell those products.

We depend on key individuals to develop our products and pursue collaborations. We are highly dependent on David Platt, Ph.D., Chief Executive Officer; Anatole Klyosov, Ph.D., Chief Scientist; and Eliezer Zomer, Ph.D., Executive Vice President, Manufacturing and Product Development, each of whom has scientific, technical or other business expertise and experience that is critical to our success. The loss of any of these persons, or failure to attract or retain other key personnel, could prevent us from pursuing collaborations or developing our products and core technologies.

We are a counterclaim defendant in a lawsuit instituted by David Platt. In January 2004, David Platt, our Chief Executive Officer, filed a lawsuit in Massachusetts against GlycoGenesys, Inc. for claims including breach of contract. GlycoGenesys subsequently named us as a counterclaim defendant alleging tortious interference and misappropriation of proprietary rights, and seeks monetary damages and injunctive relief related to our intellectual property. We and Dr. Platt intend to contest these counterclaims vigorously. In October 2006, Marlborough Research and Development, Inc. (now known as Prospect Therapeutics, Inc.) purchased selected assets of GlycoGenesys including this litigation in a bankruptcy liquidation. If we do not prevail there could be a material adverse impact on our financial position, results of operations or cash flows.

Risks Related to the Drug Development Industry

We will need regulatory approvals to commercialize our products. We are required to obtain approval from the U.S. Food and Drug Administration, or FDA, in order to sell our products in the United States and from foreign regulatory authorities in order to sell our products in other countries. The FDA’s review and approval process is lengthy, expensive and uncertain. Extensive pre-clinical and clinical data and supporting information must be submitted to the FDA for each indication for each product candidate in order to secure FDA approval. The FDA could reject an application or require us to conduct additional clinical or other studies as part of the regulatory review process. Delays in obtaining or failure to obtain FDA approvals would prevent or delay the commercialization of our products, which would prevent, defer or decrease our receipt of revenues. If we receive initial regulatory approval, our product candidates will be subject to extensive and rigorous ongoing domestic and foreign government regulation.

Our competitive position depends on protection of our intellectual property. Development and protection of our intellectual property are critical to our business. If we do not adequately protect our intellectual property, competitors may be able to practice our technologies. Our success depends in part on our ability to obtain patent protection for our products or processes in the United States and other countries, protect trade secrets, and prevent others from infringing on our proprietary rights.

Since patent applications in the United States are maintained in secrecy for at least portions of their pendency periods (published on U.S. patent issuance or, if earlier, 18 months from earliest filing date for most applications) and since other publication of discoveries in the scientific or patent literature often lags behind actual discoveries, we cannot be certain that we are the first to make the inventions to be covered by our patent applications. The patent position of biopharmaceutical firms generally is highly uncertain and involves complex legal and factual questions. The U.S. Patent and Trademark Office has not established a consistent policy regarding the breadth of claims that it will allow in biotechnology patents.

We cannot assure you that all of our patent applications will issue as patents or that the claims of any issued patents will afford meaningful protection for our technologies or products. In addition, patents issued to us or our licensors may be challenged and subsequently narrowed, invalidated or circumvented. Patent litigation is widespread in the biotechnology industry and could harm our business. Litigation might be necessary to protect our patent position or to determine the scope and validity of third-party proprietary rights, and we may not have the required resources to pursue this litigation or to protect our patent rights.

Table of Contents

Although we require our scientific and technical employees and consultants to enter into broad assignment of inventions agreements, and all of our employees, consultants and corporate partners with access to proprietary information to enter into confidentiality agreements, these agreements may not be honored.

We are a counterclaim defendant in a lawsuit instituted by our Chief Executive Officer. See “Risks Related to our Company” above.

Products we develop could be subject to infringement claims asserted by others. We cannot assure that products based on our patents or intellectual property that we license from others will not be challenged by a third party claiming infringement of its proprietary rights. If we were not able to successfully defend our patents or licensed rights, we may have to pay substantial damages, possibly including treble damages, for past infringement.

We face intense competition in the biotechnology and pharmaceutical industries. The biotechnology and pharmaceutical industries are intensely competitive. We face direct competition from U.S. and foreign companies focusing on drug delivery technologies, which are rapidly evolving. Our competitors include major, multinational pharmaceutical and chemical companies, specialized biotechnology firms and universities and other research institutions. Many of these competitors have greater financial and other resources, larger research and development staffs and more effective marketing and manufacturing organizations, than we do. In addition, academic and government institutions are increasingly likely to enter into exclusive licensing agreements with commercial enterprises, including our competitors, to market commercial products based on technology developed at these institutions. Our competitors may succeed in developing or licensing technologies and products that are more effective or less costly than ours, or succeed in obtaining FDA or other regulatory approvals for product candidates before we do.

Health care cost containment initiatives and the growth of managed care may limit our returns. Our ability to commercialize our products successfully will be affected by the ongoing efforts of governmental and third-party payers to contain the cost of health care. These entities are challenging prices of health care products and services, denying or limiting coverage and reimbursement amounts for new therapeutic products, and for FDA-approved products considered experimental or investigational, or which are used for disease indications without FDA marketing approval.

Even if we succeed in bringing any products to the market, they may not be considered cost-effective and third-party reimbursement might not be available or sufficient. If adequate third-party coverage is not available, we may not be able to maintain price levels sufficient to realize an appropriate return on our investment in research and product development. In addition, legislation and regulations affecting the pricing of pharmaceuticals may change in ways adverse to us before or after any of our proposed products are approved for marketing.

Our insurance coverage may not be adequate in all circumstances. If we commercialize our products, their use by patients could expose us to potential product liability and other claims resulting from alleged injury. This liability may result from claims made directly by consumers or by pharmaceutical companies or others selling these products. Although we currently have insurance coverage for both product liability and professional liability, we may be unable to maintain that insurance on acceptable terms. Any inability to maintain insurance coverage on acceptable terms could prevent or limit the commercialization of any products we develop.

Risks Related to Our Stock

Stock prices for pharmaceutical and biotechnology companies are volatile. The market price for securities of pharmaceutical and biotechnology companies historically has been highly volatile, and the market from time to time has experienced significant price and volume fluctuations that are unrelated to the operating performance of those companies. Fluctuations in the trading price or liquidity of our common stock may adversely affect, among other things, the interest in our stock by purchasers on the open market and our ability to raise capital.

We are not in compliance with the continuing listing requirements of the American Stock Exchange. In June 2007, we received a notice from the American Stock Exchange that it is reviewing our eligibility for continued listing of our common stock. In particular, the exchange noted that we are not in compliance with its minimum stockholders’ equity requirement in two of the last three years. In response to our plan to achieve and sustain compliance with the listing requirements, the exchange granted us an extension until October 13, 2008 to regain compliance with the standards. Failure to make progress consistent with the plan or to regain compliance with the continued listing standards by that date could result in our stock being de-listed from the exchange. If we are delisted, our ability to raise capital may be diminished.

We could issue additional common stock, which might dilute the book value of our common stock. We are authorized to issue 100,000,000 shares of common stock, of which 47,947,609 shares were issued and outstanding as of May 8, 2008. We have also proposed in our proxy statement for the 2008 annual meeting of our stockholders to increase our authorized common stock from the present 100,000,000 shares to 200,000,000 shares. Our board of directors has authority, without action or vote of our stockholders in most cases, to issue all or a part of our authorized but unissued shares. These stock issuances could be made at a price that reflects a discount from the then-current trading price of our common stock. In addition, in order to raise capital, we may need to issue securities that are convertible into or exchangeable for a significant amount of our common stock. These issuances would dilute your percentage ownership interest, which would have the effect of reducing your influence on matters on which our stockholders vote, and might dilute the book value of our common stock. You may incur additional dilution if holders of stock options, whether currently outstanding or subsequently granted, exercise their options, or if warrant holders exercise their warrants to purchase shares of our common stock.

As a “thinly-traded” stock, large sales can place downward pressure on our stock price. Our common stock, despite certain increases of trading volume from time to time, experiences periods when it could be considered “thinly traded.” Finance transactions resulting in a large amount of newly issued shares that become readily tradable, or other events that cause current stockholders to sell shares, could place downward pressure on the trading price of our stock. In addition, the lack of a robust resale market may require a stockholder who desires to sell a large number of shares to sell the shares in increments over time to mitigate any adverse impact of the sales on the market price of our stock.

SUMMARY OF CERTAIN TERMS OF THE SECURITIES

2006 Warrants

In connection with the private placement of our 7% Convertible Debentures on February 14, 2006, we issued to the purchasers of these debentures five-year warrants exercisable to purchase shares of our common stock, referred to in this prospectus as the 2006 Warrants. As of December 31, 2007, either by payment of cash or shares of our common stock, our obligations under the 7% Convertible Debentures had been discharged in full, although the 2006 Warrants remain outstanding. The 2006 Warrants are exercisable to purchase an aggregate of 10,983,605 shares of our common stock at $0.50 per share as a result of the application of anti-dilution provisions in the warrant instruments. The exercise price for the 2006 Warrants is adjustable in the event of (a) stock splits, stock dividends, combinations, reclassifications, mergers, consolidations, distributions of assets or evidence of indebtedness, sales or transfers of substantially all assets, share exchanges or similar events, and (b) dilutive issuances of common stock or common stock equivalents at an effective price per share lower than the then exercise price. If any of these events occurs, the exercise price is lowered to the price per share in, or resulting from, the subsequent event or transaction.

The form of the 2006 Warrants is filed as Exhibit 4.2 to our Current Report on Form 8-K filed with the SEC on February 15, 2006. The summary of the 2006 Warrants set forth above is qualified in its entirety by reference to that exhibit.

Series A Preferred and 2008 Warrants

In a private placement that we completed on February 4, 2008, we sold 1,742,500 units of securities, each unit comprised of (i) one share of our Series A 12% Convertible Preferred Stock, referred to in this prospectus as Series A Preferred; (ii) a five-year warrant exercisable for $1.50 to purchase one share of our common stock; and (iii) a five-year warrant exercisable for $2.00 to purchase one share of our common stock, referred to collectively in this prospectus as the 2008 Warrants.

The holders of Series A Preferred are entitled to receive dividends of 12% per annum on March 30 and September 30 payable at our option in cash or shares of common stock valued per share at the higher of $1.00 or 100% of the weighted average price of our shares of common stock for the 20 consecutive trading days prior to the applicable dividend payment date. On the assumption that we elect to pay future dividends on Series A Preferred in shares of common stock, we are registering a sufficient number of shares of common stock that, in the aggregate, would be issuable on the first six dividend payment dates. In April 2008, we issued 82,817 shares of common stock as the dividend on Series A Preferred for the March 30, 2008 dividend payment date. The shares of Series A Preferred are convertible at any time at the option of the holder on a one-for-one basis into shares of our common stock. The conversion rate is subject to adjustment in the event of a stock dividend, stock split or combination, reclassification or similar event. We have the right to require conversion if the closing price of the common stock exceeds $3.00 for 15 consecutive trading days and a registration statement covering the resale of the shares of common stock issuable upon this mandatory conversion is then in effect. The shares of Series A Preferred vote as a class with the shares of our common stock.

Table of Contents

The 2008 Warrants (inclusive of 2008 Warrants paid as compensation to placement agents), which are exercisable beginning on the 181st day after the February 4, 2008 issue date, are to purchase in the aggregate up to 3,493,400 shares of our common stock. The exercise price for the 2008 Warrants is adjustable in the event of stock splits, stock dividends, combinations, reclassifications, mergers, consolidations, distributions of assets or evidence of indebtedness, sales or transfers of substantially all assets, share exchanges or similar events.

The forms of the Certificate of Designation for the Series A Preferred and the two series that constitute the 2008 Warrants are filed as Exhibits 3.2, 10.3 and 10.4, respectively, to our Current Report on Form 8-K filed with the SEC on October 9, 2007. The summary of the Series A Preferred and the 2008 Warrants set forth above is qualified in its entirety by reference to those exhibits.

SELLING STOCKHOLDERS

This prospectus relates to the resale from time to time of up to a total of 16,825,073 shares of our common stock by the selling stockholders, comprising:

 

   

10,983,606 shares of common stock issuable upon exercise of the 2006 Warrants, referred to in this prospectus as the 2006 Warrant Shares;

 

   

1,742,500 shares of common stock issuable upon conversion of the Series A Preferred, referred to in this prospectus as the Conversion Shares;

 

   

605,567 shares of common stock issuable as stock dividends on the Series A Preferred, referred to in this prospectus as the Dividend Shares, issued or issuable in respect of the initial six Series A Preferred dividend payment dates; and

 

   

3,493,400 shares of common stock issuable upon exercise of the 2008 Warrants, referred to in this prospectus as the 2008 Warrant Shares.

The following table, based upon information currently known to us, sets forth as of May 8, 2008: (i) the number of shares held of record or beneficially by the selling stockholders as of that date, (ii) the number of shares that may be offered under this prospectus, and (iii) a footnote reference to any material relationship between us and the selling stockholder, if any.

The number of shares beneficially owned by each selling stockholder named in the table below is determined under rules of the Securities and Exchange Commission (SEC) and the information is not necessarily indicative of beneficial ownership for any other purpose. Under those rules, beneficial ownership includes any shares to which the individual or entity has sole or shared voting power or investment power and also any shares that the individual or entity has the right to acquire within 60 days after May 8, 2008 through the exercise of any stock option, warrant or other right, or conversion of any security. The inclusion in the table below of any shares deemed beneficially owned does not constitute an admission of beneficial ownership of those shares.

None of the selling stockholders is a broker-dealer or an affiliate of a broker-dealer, other than Rodman & Renshaw, Inc. and Chelsea Financial Services, each of whom obtained its shares offered in this prospectus as placement agent compensation.

* Amount less than one percent.

Percentage calculations are based on 47,947,609 shares of our common stock issued and outstanding as of May 8, 2008 (inclusive of Dividend Shares issued in respect of the March 30, 2008 dividend payment date).

 

(1) This column includes, as applicable, (i) the 2006 Warrant Shares, (ii) the Conversion Shares, (iii) the Dividend Shares issued in respect of the March 30, 2008 dividend payment date (but no other Dividend Shares), (iv) shares issuable upon exercise or conversion of any other securities that are exercisable or convertible within sixty days of May 8, 2008, and (v) any outstanding shares of common stock held. This column does not include any other Dividend Shares or any 2008 Warrant Shares because those shares are not deemed beneficially owned as of the date of this prospectus.
(2) This column, with respect to each of the first ten named selling stockholders, represents that selling stockholder’s 2006 Warrant Shares, and, with respect to each of the remaining named selling stockholders, represents the sum of that selling stockholder’s Conversion Shares, Dividend Shares and 2008 Warrant Shares.
(3) This column assumes that all shares shown as being beneficially held by each selling stockholder in Column 1 (except shares being offered by this prospectus) continue to be beneficially held by that selling stockholder following completion of the offering. This column also assumes that all shares shown as being offered pursuant to this prospectus in Column 2 are sold by the selling stockholders in the offering. We have assumed this because we cannot estimate the number of shares that will be held by any of the selling stockholders after completion of the offering. We do not know when or in what amounts a selling stockholder may offer shares for sale. The selling stockholders may not sell any or all of the shares offered by this prospectus. There are currently no agreements, arrangements or understandings with respect to any of the shares.

PLAN OF DISTRIBUTION

Each selling stockholder and any of their pledgees, assignees and successors-in-interest may, from time to time, sell any or all of his, her or its shares on the American Stock Exchange or any other stock exchange, market or trading facility on which the shares are traded or in private transactions. These sales may be at fixed or negotiated prices. A selling stockholder may use any one or more of the following methods when selling shares:

 

   

ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

 

   

block trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;

 

   

purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

 

   

an exchange distribution in accordance with the rules of the applicable exchange;

 

   

privately negotiated transactions;

 

   

settlement of short sales entered into after the effective date of the registration statement of which this prospectus is a part;

 

   

broker-dealers may agree with the selling stockholders to sell a specified number of shares at a stipulated price per share;

 

   

through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

 

   

a combination of any of these methods of sale; or

 

   

any other method permitted pursuant to applicable law.

The selling stockholders may also sell shares under Rule 144 under the Securities Act of 1933, as amended (the “Securities Act”), if available, rather than under this prospectus.

Broker-dealers engaged by the selling stockholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the selling stockholders (or, if any broker-dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with NASDR Rule 2440; and in the case of a principal transaction a markup or markdown in compliance with NASDR IM-2440.

In connection with the sale of shares, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the shares in the course of hedging the positions they assume. The selling stockholders may also sell shares short and deliver these shares to close out their short positions, or loan or pledge shares to broker-dealers that in turn may sell these shares. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to that broker-dealer or other financial institution of shares offered by this prospectus, which shares that broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect that transaction).

The selling stockholders and any broker-dealers or agents that are involved in selling the shares may be deemed to be “underwriters” within the meaning of the Securities Act in connection with those sales. In that event, any commissions received by those broker-dealers or agents and any profit on the resale of the shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Each selling stockholder has informed us that it does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the shares. In no event shall any broker-dealer receive fees, commissions and markups which, in the aggregate, would exceed eight percent (8%) of the gross proceeds of any sale.

We are required to pay certain fees and expenses incurred by us incident to the registration of the shares. We have agreed to indemnify the selling stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.

Because selling stockholders may be deemed to be “underwriters” within the meaning of the Securities Act, they will be subject to the prospectus delivery requirements of the Securities Act including Rule 172 there under. In addition, any securities covered by this prospectus which qualify for sale pursuant to Rule 144 under the Securities Act may be sold under Rule 144 rather than under this prospectus. There is no underwriter or coordinating broker acting in connection with the proposed sale of the resale shares by the selling stockholders.

We agreed to keep this prospectus effective until the earlier of (i) the date on which the shares may be resold by the selling stockholders without registration and without regard to any volume limitations by reason of Rule 144 under the Securities Act or any other rule of similar effect or (ii) all of the shares have been sold pursuant to this prospectus or Rule 144 under the Securities Act or any other rule of similar effect. The shares will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the shares may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

Under applicable rules and regulations under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), any person engaged in the distribution of the shares may not simultaneously engage in market making activities with respect to the common stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the selling stockholders will be subject to applicable provisions of the Exchange Act and the rules and regulations there under, including Regulation M, which may limit the timing of purchases and sales of the shares by the selling stockholders or any other person. We will make copies of this prospectus available to the selling stockholders and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).

LEGAL MATTERS

The validity of the shares of common stock being offered by this prospectus has been passed upon for Pro-Pharmaceuticals, Inc. by Greenberg Traurig, LLP of Boston, Massachusetts.
