  • Triparanol (MER-29) is a potent cholesterol biosynthesis inhibitor blocking the 24-dehydrocholesterol reductase (24-DHCR). Triparanol can interfere with posttranslational modification of Hedgehog signaling molecules as well as the sterol sensing domain of its receptor PTCH1, leading to down-regulation of Hh signaling. Triparanol suppresses human tumor growth[1][2].

In Vitro Triparanol can block proliferation and induce apoptosis in multiple human cancer cells including lung, breast, liver, pancreatic, prostate cancer and melanoma cells, and growth inhibition can be rescued by exogenous addition of cholesterol[2].
