BTC Inhibitors

BTC inhibitors, short for Biliary Tract Cancer inhibitors,represent a class of chemical compounds specifically designed to target and inhibit the activity of biomolecules associated with the development and progression of biliary tract cancers (BTCs). BTCs encompass a group of malignancies that originate in the bile ducts, including intrahepatic and extrahepatic cholangiocarcinomas and gallbladder cancers. These tumors often exhibit aggressive behavior and are typically diagnosed at an advanced stage, posing a significant challenge. BTC inhibitors aim to address this challenge by focusing on the underlying molecular mechanisms driving BTC development. The development of BTC inhibitors is rooted in our understanding of the molecular pathways and genetic alterations that contribute to the initiation and growth of BTCs. Researchers have identified various key molecules and signaling pathways involved in BTC pathogenesis, such as mutations in genes like KRAS, TP53, and IDH1/2, as well as dysregulated signaling pathways like the Notch and Wnt pathways. BTC inhibitors are designed to interfere with these specific molecular targets or signaling pathways, either by directly binding to the target molecules or by modulating their activity through various mechanisms.
