Item 8.01 Other Events.

On June 7, 2007, Lipid Sciences, Inc. issued a press release entitled “Lipid Sciences Announces Validation of Proprietary Peptide That Mimics Key Functions of Natural Human HDL.” The press release reported that the Company’s lead HDL Mimetic Peptide compound, LSI 518P, and a back-up compound have been identified and validated with an extensive battery of in vitro assays. In these tests, the selected mimetic peptide candidates effluxed cholesterol via the ABCA1 transporter metabolic pathway—known to be optimal for removing cholesterol from arterial plaque via the reverse cholesterol transport mechanism—at a rate similar to naturally-occurring HDL. A copy of the press release is furnished as Exhibit 99.1 to this report.

The information in this Item 9.01, including 99.1 exhibit hereto, is being furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section. In addition, the information in this Item 2.02 shall not be incorporated by reference into any document filed under the Securities Act of 1933, as amended, or the Exchange Act, regardless of any general incorporating language in such filing, except as shall be expressly set forth by specific reference in such filing.
