Abstract

Multidrug resistance (MDR) refers to the cross-resistance of Cancer cells to one drug, accompanied by Other drugs with different mechanisms and structures, which is one of the main obstacles of clinical chemotherapy. Overexpression of P-glycoprotein (P-gp) was an extensively studied cause of MDR. Therefore, inhibiting P-gp have become an important strategy to reverse MDR. In this study, two series of triazole-tetrahydroisoquinoline-core P-gp inhibitors were designed and synthesized. Among them, compound I-5 had a remarkable reversal activity of MDR activity and the preliminary mechanism study was also carried out. All the results proved that compound I-5 was considered as a promising P-gp-mediated MDR reversal candidate.
