But what if a drug could stimulate the body into producing some of the same effects of exercise —....Such a pill may be on the way. Several scientists are testing compounds that apparently can do this — and people wouldn’t even have to move at all to benefit.
“Our goal is to understand these circuits,” says Ronald Evans, director of the gene expression laboratory at the Salk Institute for Biological Studies in La Jolla, Calif. “We are taking this concept and trying to develop a drug that can help us game the system that is naturally activated during exercise.”...
Ali Tavassoli, a professor of chemical biology at Britain’s University of Southampton, has discovered a drug known as compound 14 that works “by fooling cells into thinking they have run out of energy,” Tavassoli says. It does this through a series of
molecular actions that spur cells into metabolizing sugar, which produces energy, he says....
