Sirtris Awarded Patent

Xconomy Boston — 

Sirtris Pharmaceuticals (NASDAQ: SIRT) of Cambridge, MA, said today that the U.S. Patent and Trademark Office has issued to Sirtris the first patent ever granted for a class of compounds that activate SIRT1, a human enzyme that is the focus of much of the company’s research. In lab animals, Sirtris has found, activating SIRT1 lowers glucose levels and improves insulin sensitivity; the patent covers a potential Type 2 diabetes treatment that the company plans to test in human safety trials this year.
