Description
STF-62247 (315702-99-9) specifically induces autophagic cell death in VHL (von Hippel-Lindau)-deficient renal carcinoma cells both in vitro (IC50=625 nM) and in vivo. Renal cell carcinoma cell lines were radiosensitized by induction of autophagy following treatment with STF-62247. Cell permeable
Uses
Autophagy Inducer, STF-62247 is selectively kills RCC cells that have lost VHL tumor suppressor activity.
Definition
ChEBI: N-(3-methylphenyl)-4-pyridin-4-yl-2-thiazolamine is a substituted aniline.
in vitro
in vitro study demonstrated that stf-62247 exhibited selectively cytotoxicity and tumor growth inhibitory activity towards wild-type vhl and vhl-deficient renal cell carcinoma (rcc) in a hif-independent manner with ic50 of 16 μm and 0.625 μm, respectively. in addion, stf-62247 also resulted in cell apoptosis by inducing acidification and increasing autophagy in vhl-deficient cells. [1]
in vivo
animal experiments for stf-62247 activity were performed according to institutional and national guidelines and approved by stanford university's administrative panel on laboratory animal care. based on an in vivo mouse model, it was found that intraperitoneal injection of stf-62247 at a dose of 8 mg/kg significantly inhibited tumor growth of vhl-deficient sn12c tumor cells. [1]
IC 50
stf-62247 inhibits tumor growth in wild-type vhl and vhl-deficient renal cell carcinoma (rcc) in a hif-independent manner with ic50 of 16 μm and 0.625 μm, respectively.
