Taladegib hydrochloride
Based on 2 publication(s) in Google Scholar
Taladegib (LY2940680) hydrochloride is a Smoothened (SMO) antagonist. Taladegib hydrochloride inhibits the Hedgehog signaling pathway, with an IC50 of 5.5 nM for suppressing GLI1 mRNA expression in DAOY cells and an IC50 of 7.6 nM in CGNP cell proliferation assays. Taladegib hydrochloride binds to the extracellular loop region (site 1) of the transmembrane domain of the SMO receptor, competes with cyclopamine for SMO binding, and thereby inhibits Gli-dependent transcription. Taladegib hydrochloride can be used in studies of Hedgehog pathway-related cancers.
