生物活性

MK-4101 is a Smoothened (SMO) antagonist (IC₅₀ of 1.1 µM for 293 cells ) and also a potent inhibitor of the hedgehog pathway (IC₅₀ of 1.5 µM for mouse cells; IC₅₀ of 1 µM for KYSE180 oesophageal cancer cells). MK-4101 has robust antitumor activity that inhibits tumor cell proliferation and induces extensive apoptosis.

体外研究

MK-4101 inhibits Hh signaling both in a reporter gene assay in an engineered mouse cell line with an IC₅₀ of 1.5 µM, and in human KYSE180 oesophageal cancer cells with an IC₅₀ of 1 µM. MK-4101 displaces a fluorescently-labeled cyclopamine derivative from 293 cells expressing recombinant human SMO with an IC₅₀ of 1.1 µM, implying that the compound binds to SMO. MK4101 also inhibits the proliferation of medulloblastoma cells derived from neonatallyirradiated Ptch1 mice in vitro with an IC₅₀ of 0.3 µM.
MK-4101 (10 µM; 60 hours, 72 hours; medulloblastoma or BCC cells) treatment shows cell cycle arrest with a nearly complete disappearance of the S phase subpopulation, a prominent increase of the G1 population and, to a minor extent, of the G2 population.
MK-4101 (10 µM; medulloblastoma or BCC cells) treatment significantly reduces cyclin D1 protein and accumulation of cyclin B1 protein.

体内研究

MK-4101 (40-80 mg/kg; oral administration; for 3.5 weeks; CD1 nude female mice) treatment shows tumor growth inhibition (40 and 80 mg/kg ) and tumor regression at the highest dose (80 mg/kg). MK-4101 treatment shows a dose-dependent down-regulation of Gli1 mRNA. The maximum effect for tumor inhibition and hedgehog pathway downregulation is achieved at 80 mg/kg.

Animal Model:	5-weeks old CD1 nude female mice with medulloblastoma/BCC cells
Dosage:	40 or 80 mg/kg once a day, 80 mg/kg twice a day
Administration:	Oral administration; for 3.5 weeks
Result:	Showed tumor growth inhibition (40 and 80 mg/kg ) and tumor regression at the highest dose (80 mg/kg).
