Description: VER-49009 is a potent HSP90 inhibitor. VER-49009 inhibits Hsp90 with an IC50 value of 47 nM. VER-49009 produces a cellular antiproliferative GI50 value of 685 nM when tested against a human cancer cell line panel. Consistent with inhibition of Hsp90, VER-49009 induces the expression of Hsp27 and Hsp72 while reducing the client proteins C-RAF, B-RAF, survivin, and PRMT5, causing cell cycle arrest and apoptosis.
