Description
Curator's Comment: description was created based on several sources, including: https://www.ncbi.nlm.nih.gov/pubmed/19244114 | https://www.ncbi.nlm.nih.gov/pubmed/24292262

VER-50589 is an isoxazole compound that inhibits a heat shock protein Hsp90. Mean cellular antiproliferative GI(50) value for VER-50589 for a human cancer cell line panel were 78 nM/L, showing a 9-fold potency gain for the isoxazole. VER-50589 shows favorable pharmacokinetics and impairs tumor growth (colon cancer) in animal model. Glioblastoma cells do not acquire resistance to VER-50589 and resistance to other Hsp90 inhibitors does not produce cross-resistance to VER-50589.

VER-50589 inhibited HUVEC proliferation with GI50 values of 19 nM/L, respectively. The nontumorigenic human breast (MCF10a) and prostate (PNT2) epithelial cells exhibited higher GI50 values for VER- 50589 when compared with their respective mean GI50 (330 nM/l and 179.5 nM/l respectively) values against cancer cells.
