Chemical Name: 9,13-Dihydroxy-8,14,19-trimethoxy-4,10,12,16-tetramethyl-2-azabicyclo[16.3.1]docosa-4,6,10,18,21-pentaene-3,20,22-trione, 9-carbamate

Biological Activity

Selectively inhibits heat shock protein 90 (Hsp90). Binds to the ATP site of Hsp90 (Kd = 1.2 μM) and inhibits its chaperone activity. Consequently inhibits activities of oncogenic kinases (e.g. src, Raf), p53 and steroid receptors. Demonstrates antiproliferative effect on breast cancer stem-like cells.
