Herbimycin A is the major analogue of a complex of benzoquinone ansamycin antibiotics isolated from a Streptomyces hygroscopicus. Herbimycin A inhibits the 90-kD heat-shock protein (Hsp90) which provides essential chaperone support to various signal transduction molecules, including including certain steroid hormone receptors and select kinases. Herbimycin has also been shown to inhibit protein tyrosine kinase and angiogensis.
