Hoping Two Drugs Carry a Side Effect: Longer Life

Sirtris has two drugs in clinical trials. One is being tested against Type 2 diabetes, one of the many diseases of aging that the company’s scientists hope the drugs will avert. With success against just one such disease, the impact on health “could be possibly transformational,” said Dr. Patrick Vallance, head of drug discovery at GlaxoSmithKline.

The new drugs are called sirtuin activators, meaning that they activate an enzyme called sirtuin. The basic theory is that all or most species have an ancient strategy for riding out famines: switch resources from reproduction to tissue maintenance. A healthy diet but with 30 percent fewer calories than usual triggers this reaction in mice and is the one intervention that reliably increases their life span. The mice seem to live longer because they are somehow protected from the usual diseases that kill them.
