Genaera Corporation Presents Data on Mechanism of Inhibition of PTP-1B for Trodusquemine (MSI-1436) at Federation of American Societies for Experimental Biology (FASE...( PLYMOUTH MEETING Pa. July 14 /- G...),Health

PLYMOUTH MEETING, Pa., July 14 /PRNewswire-FirstCall/ -- Genaera Corporation (Nasdaq: GENR) announced today the presentation of new preclinical data on trodusquemine (MSI-1436), a novel inhibitor of PTP-1B and Genaera's lead drug candidate for the treatment of type 2 diabetes and obesity, during the 10th Biennial FASEB Summer Research Conference Protein Phosphatases in Snowmass Village, Colorado. The poster presentation entitled, "Trodusquemine (MSI-1436), An Allosteric Inhibitor of Protein Tyrosine Phosphatase 1B," concluded that MSI-1436 is a selective, reversible and noncompetitive inhibitor of PTP-1B that enhances insulin signaling through potent PTP-1B inhibition both in vivo and in vitro.

"The search to discover PTP-1B inhibitors as a therapeutic target for the treatment of obesity and type 2 diabetes has long been a goal of drug development but achieving the selectivity necessary to demonstrate safety has been a significant hurdle. The new information on the mechanism by which MSI-1436 inhibits PTP-1B supports its first-in-class status," stated Jack Armstrong, President and Chief Executive Officer of Genaera. "MSI-1436 is the only reversible, noncompetitive inhibitor of PTP-1B in clinical stage development. It is the allosteric nature of MSI-1436 and its ability to reversibly inhibit PTP-1B that is believed to be the key to the safety we have observed in Phase 1. We anticipate this will be attractive to both potential partners and clinicians as we obtain further evidence of the efficacy and safety of MSI-1436 in future studies."

Inhibition of PTP-1B, a non-receptor isoform of the protein tyrosine phosphatase family, by MSI-1436 has been shown to reduce food intake, induce weight loss, and increase insulin sensitivity
