Использование

PF-5274857 is a potent and selective Smoothened (Smo) antagonist, inhibits Hedgehog (Hh) signaling, respectively, and can penetrate the blood–brain barrier.

Ферментативный ингибитор

This brain-penetrating Smoothened (Smo) antagonist (FW = 436.96 g/mol; CAS 1373615-35-0), also known as 1-(4-(5-chloro-4-(3,5-dimethylpyridin- 2-yl)pyridin-2-yl)piperazin-1-yl)-3-(methylsulfonyl)propan-1-one, potentlyand selectively inhibits Hedgehog (Hh) signaling (IC50 = 5.8 nM; Ki = 4.6 nM). PF-5274857 elicits robust antitumor activity in a mouse model of medulloblastoma (IC50 = 8.9 nmol/L), with down-regulation of Gli1, a marker closely linked to the tumor growth inhibition in patched (+/-) medulloblastoma mice. PF-5274857 also inhibits Smo activity within the brain of primary medulloblastoma mice, improving survival. PF-5274857 is orally available and metabolically stable in vivo. Other Hedgehog inhibitors include: GANT61, BMS-833923, Purmorphamine, SANT-1, LY2940680, Cyclopamine, LDE225 (or NVP-LDE225, Erismodegib), Vismodegib (GDC-0449)
