A novel series of P‐glycoprotein (P‐gp)‐mediated multidrug resistance (MDR) inhibitors bearing a triazol‐phenethyl‐tetrahydroisoquinoline scaffold were designed and synthesized via click chemistry. Most of the synthesized compounds showed higher reversal activity than verapamil (VRP). Among them, the most potent compound 5 showed a comparable activity with the known potent P‐gp inhibitor WK‐X‐34 with lower cytotoxicity (IC50s > 100 μm). Compared with VRP, compound 5 exhibited more potency in increasing drug accumulation in K562/A02 MDR cells. Moreover, compound 5 persisted longer chemo‐sensitizing effect (>24 h) than VRP (<6 h) with reversibility. Given the low intrinsic cytotoxicity and the potent reversal activity, compound 5 may represent a promising candidate for developing P‐gp‐mediated MDR inhibitor.
