Indeed, adding r8 to vancomycin, a first-line defense against MRSA, made the new drug hundreds of times more effective, according to experiments conducted by Antonoplis, Zang, and their advisers, Lynette Cegelski, an associate professor of chemistry, and Paul Wender, the Francis W. Bergstrom Professor of Chemistry. The same strategy, the researchers believe, could apply beyond MRSA to other drugs and infections.

"You don't have to invent a new drug. You just have to fix the problems with existing drugs," said Wender, who is also a member of Stanford Bio-X, the Stanford Cancer Institute, and Stanford ChEM-H.
