PF-04929113 (SNX-5422)是一种有效的,选择性的HSP90抑制剂,Kd为41 nM,且诱导Her-2降解,IC50为37 nM。Phase 1/2。
Information
PF-04929113 (SNX-5422) PF-04929113 (SNX-5422) is a potent and selective HSP90 inhibitor with K d of 41 nM and induces Her-2 degradation with IC50 of 37 nM. Phase 1/2.
In vitro
PF-04929113 is a small-molecule Hsp90 inhibitor based on the 6,7-dihydro-indazol-4-one scaffold. PF-04929113 developed by Serenex, converts to SNX-2122, which is the active Hsp90 inhibitor form. PF-04929113 exhibits potent effects on Her-2 stability and causes expected up-regulation of Hsp70. PF-04929113 shows potent antiproliferative activity against a broad range of cancer cell types, e.g. MCF-7 (IC50=16 nM), SW620 (IC50=19 nM), K562 (IC50=23 nM), SK-MEL-5 (IC50=25 nM), and A375 (IC50=51 nM).
In vivo
PF-04929113 inhibits human MM cell growth in vivo, and immuno-histochemical analysis shows PF-04929113 significantly inhibits p-ERK and p-Akt in treated mice. Meanwhile, PF-04929113 treatment significantly decreases the percentage of CD31+ cells and MVD, consistent with an inhibitory effect on angiogenesis in vivo. A 50 mg/kg administration of PF-04929113 delivered 3 times per week significantly delays castrate-resistant LNCaP tumor growth and prolongs cancer specific survival. Immuno-histochemical analysis indicates increased SP70 expression, and decreases Ki67, Akt, and AR expression, after treatment with PF-04929113. Inhibition of tumor progression by PF-04929113 may result from a combination of decreased proliferative (reduced Ki67 and Akt expression) or increased apoptosis (increased ApopTag staining) rates.
