Biological Activity

17-dmag is an inhibitor of hsp90 with ic50 value of 62±29nm [1].17-dmag can bind to the atp-binding motif of hsp90 and inhibit the protein chaperoning activity of hsp90. it will cause misfolding and subsequent degradation of hsp90’s client proteins, such as egfr, akt, mutant p53, and ikk. since there is more specific conformation hsp90 required for 17-dmag binding in tumor cells and many client proteins of hsp90 contribute to tumor cell growth, 17-dmag is usually more toxic to tumor cells than to normal cells [2].17-dmag is reported as an antitumor agent with more broadly exploitable activity and more pharmaceutically tractable characteristics in the in vitro and initial in vivo assay. 17-dmag can effect cell growth when treating the nci 60 cell lines with it, the mean gi50 is 0.053mm. the in vivo activity of 17-dmag is tested in four melanoma models using the freiburg human tumor xenograft panel and two lung xenografts. it shows that 17-dmag has high activity in the two lung xenografts and two of the four melanoma models, but not in another two, mexf 462 and mexf 514 [3].

Enzyme inhibitor

This potent Hsp90 inhibitor (FWHCl-Salt = 653.21 g/mol; CAS 467214-21-7), also named 17-DMAG and 17-demethoxy-17-[[2-(dimethylamino) ethyl]amino]geldanamycin, targets Heat Shock Protein-90 (IC50 = 62 nM in a cell-free assay). (See also Ansamycin; Deguelin; Derrubone; Ganetespib; Geldanamycin; Herbimycin; Macbecin; Radicicol; Tanespimycin; and the nonansamycin Hsp90 inhibitor KW-2478)
