N-(3'-(Dimethylamino)propyl)amides based on 18βH-glycyrrhetinic acid retain P-glycoprotein inhibitory and MDR-reversing activities.
Multidrug resistance (MDR) is a major obstacle to successful cancer chemotherapy, primarily mediated by P-glycoprotein (P-gp/ABCB1), which actively effluxes structurally unrelated anticancer drugs. We previously reported Sol-DMAP, an 18βH-glycyrrhetinic acid-derived P-gp inhibitor that reverses chemoresistance and exhi...
