Design, synthesis, and evaluation of a radicicol and geldanamycin chimera, radamide

Org Lett. 2004 Nov 25;6(24):4459-62. doi: 10.1021/ol048266o.

Abstract

A chimera composed of the natural products radicicol and geldanamycin has been prepared through an amide linkage connecting the resorcinol moiety of radicicol to the quinone ring of geldanamycin. The inhibitory activity of these compounds was determined by their ability to inhibit Hsp90's inherent ATPase activity along with degradation of the Hsp90 client protein, HER-2 in MCF-7 breast cancer cells.
