LY2940680 binds to the Smo receptor and potently inhibits Hh signaling.
Targets
Smo
IC50
In Vitro
LY2940680 inhibits cancer growth in cell lines containing a mutation in the gene encoding Smoothened that researchers had previously observed in patient with cancer who developed resistance to vismodegib. [1]
In Vivo
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]
Clinical Trials
LY2940680 is currently being tested in phase 1 trials for people with a range of solid tumors.
Features
Combination Therapy
Description
LY2940680 inhibits the functional activity of resistant Smo mutant (D473H) produced by treatment with GDC-0449 (a Smo antagonist). sup>[2]
