Formula: C24H31N3O3
Target: HSP90
Description:
AT13387, discovered by a high-throughput x-ray craystallography fragment-based platform, is a non-geldanamycin inhibitor of heat shock proterin 90 (HPS90), a molecule chaperone regulating signal transduction pathways for cell growth and survival. It has high affinity for binding HSP90 (Kd = 0.5nM) and exhibited an in vitro cytotoxicity showing a median EC50 value of 41 nM. The antitumor activity of AT13387 against solid tumor and leukemia models is similar to alvespimycin.

Biological Activity:
AT13387 is a potent inhibitor of the proliferat ion and survival of many different cell lines (such as MES-SA cell line) from a variety of different tumor types. Across a panel of 30 tumor cell lines, AT13387 potently inhibits cell proliferation with GI50 values in the range 13-260 nM. AT13387 inhibits proliferation of the non-tumorigenic human prostate epithelial cell line PNT2 with a GI50 value of 480 nM. The inhibition of a number of isolated kinases by AT13387 is also investigated including CDK 1, CDK 2, CDK4, FGFR3, PKB-b, JAK2, VEGFR2, PDGFRβ and Aurora B. None of the tested kinases are significantly inhibited at concentrations below 30 µM.
