SANT-1 (CAS 304909-07-7)

SANT-1, a member of the santacruz compound family, is a small molecule inhibitor that specifically targets protein kinase C (PKC), an enzyme involved in various cellular processes. This inhibitor has gained significant attention in scientific research due to its ability to selectively target and modulate specific proteins. One of SANT-1′s notable actions is its role as a membrane-permeable antagonist of the Shh (Sonic Hedgehog) signaling pathway. By directly binding to Smo (Smoothened), SANT-1 effectively inhibits Smo in both oncogenic and wild-type forms. Furthermore, when combined with the HDAC inhibitor SAHA, SANT-1 demonstrates promising suppression of cellular proliferation and colony formation in Gemcitabine-resistant pancreatic adenocarcinoma cell lines Panc-1 and BxPC-3. In addition to its impact on the Shh signaling pathway, SANT-1 may act to modulate the activity of various proteins involved in cellular processes like cell cycle regulation, apoptosis, and inflammation. It also influences the activity of enzymes participating in metabolic processes, including fatty acid oxidation and glycolysis. The mechanism of SANT-1 involves acting as a competitive inhibitor of SANT-1 itself. By binding to the active site of the enzyme, it effectively blocks the substrate from binding, leading to the inhibition of the enzyme′s activity.
