Taladegib (LY2940680)S2157

LY2940680 has excellent pharmacokinetic properties in rodent and non-rodent species. LY2940680 administrated orally treats Ptch^+/- p53^-/- transgenic mice which spontaneously develop medulloblastoma, produces remarkable efficacy and significantly improves their survival. LY2940680 reveals rapid kinetics of anti-tumor activity through magnetic resonance imaging of these mice, and LY2940680 induces Caspase-3 activity and reduces proliferation by immunohistochemistry analysis of medulloblastoma tumors. LY2940680 inhibits Hh regulated gene expression in the subcutaneous xenograft tumor stroma and produces significant anti-tumor activity. ^[2]
