MedKoo CAT#: 203220

CAS#: 167465-36-3 (3HCl)

Description: Zosuquidar, also known as LY-335979, is a potent P-glycoprotein (P-gp) inhibitor, which binds with high affinity to P-glycoprotein and inhibits P-glycoprotein-mediated multidrug resistance (MDR). P-glycoprotein, encoded by the MDR-1 gene, is a member of the ATP-binding cassette superfamily of transmembrane transporters and prevents the intracellular accumulation of many natural product-derived cytotoxic agents.
