Alvespimycin HCl (17-DMAG)

Catalog #: 27730-1
Size: 25 mg
MW: 653.2 Da
CAS Registry #: 467214-21-7
Formula: C32H48N4O8 • HCl
Target: HSP90
Alvespimycin hydrochloride is the hydrochloride salt of alvespimycin, 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.
Alvespimycin HCl, also known as 17-DMAG, is a potent, water-soluble HSP90 inhibitor. Alvespimycin has diverse anti-tumor actions and has potential in treating a number of different types of cancers, including ovarian, prostate, melatnoma, non-small-cell lung cancer, and several leukemias (chronic lymphocytic, acute myeloid). This compound also suppresses inflammation by interfering with signaling through the NF-κB pathway.
