Alvespimycin HCl

    WARNING: This product is for research use only, not for human or veterinary use.

MedKoo CAT#: 200170

CAS#:  467214-21-7(HCl)

Description: Alvespimycin is an analogue of the antineoplastic benzoquinone antibiotic geldanamycin. Alvespimycin binds to HSP90, a chaperone protein that aids in the assembly, maturation and folding of proteins. Subsequently, the function of Hsp90 is inhibited, leading to the degradation and depletion of its client proteins such as kinases and transcription factors involved with cell cycle regulation and signal transduction. Check for active clinical trials or closed clinical trials using this agent.
