Abstract

Many bacteria and fungi produce natural products that are toxic to other microorganisms and have a variety of physiological effects in animals. Recent studies have revealed that, in several cases, the targets of these agents are components of conserved signal-transduction cascades. This article looks at the mechanisms of action of five natural products--the immunosuppressants cyclosporin A, FK506 and rapamycin, and the antiproliferative agents wortmannin and geldanamycin. These mechanisms reveal the importance of signal-transduction cascades as targets for therapeutic intervention and the enormous utility of studies of natural-product action in simple model genetic systems.
