Make a clean breast of it: The generation of a library of pochonin D derivatives by a solid-phase approach has led to the discovery of pochoxime (see scheme), a potent inhibitor of the heat-shock protein 90, with over 100-fold improved incellular activity. Pochoxime was found to be effective in breast tumor xenografts, leading to a reduction in the tumor size.
