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 ( IC 50 s > 100 μ m ). Compared with VRP , compound 5 exhibited more potency in increasing drug accumulation in K 562/ A 02 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.
