Research use only, not for human use.

LY2940680 (Taladegib) is potent Smoothened (SMO) receptor antagonist.

LY2940680 (Taladegib) is potent Smoothened (SMO) receptor antagonist, potently inhibits Hedgehog (Hh) signaling with IC50 of 6.3 nM in Gli-luc reporter assyas; inhibits medulloblastoma cell proliferation isolated from Ptch+/–p53–/– mice with IC50 of 43.5 nM; demonstrates anti-tumor activity in vivo with advanced basal cell carcinoma (BCC) and other malignancies.Ovarian Cancer Phase 2 Clinical(In Vitro):Taladegib, a small-molecule antagonist of the smoothened receptor, shows a slight inhibitory effect on cell proliferation without differences between mucin- (IC50: Taladegib=49.8±4.5 μM) and mixed- Cholangiocarcinoma (CCA) (IC50: Taladegib=61.2±21.1 μM). The IC50 for Taladegib inhibition of [3H]MRT-92 binding is right shifted (3- to 100-fold) for the S387AECL2, L325F3.36f, and D473H6.54f mutants but did not differ from that of WT receptor for the other mutants. The ability of SANT-1 to inhibit [3H]MRT-92 binding to V329F3.40f and T466F6.47f mutants is abolished, and it is severely impaired for L325F3.40f, I408F5.51f, and M525G7.45f mutants (4- to 140-fold drop of the IC50), but is not modified for the S387AECL2 mutant. Taken together, these data confirm our docking hypothesis that MRT-92-binding mode differs from that of either Taladegib or SANT-1 by simultaneously occupying binding sites 1 and 2.
