The major drawbacks of P-glycoprotein (P-gp) inhibitors at the clinical stage make the development of new P-gp inhibitors challenging and desirable. In this study, we reported our structure-activity relationship studies of 4-indolyl quinazoline, which led to the discovery of a highly effective and orally active P-gp inhibitor, YS-370. YS-370 effectively reversed multidrug resistance (MDR) to paclitaxel and colchicine in SW620/AD300 and HEK293T-ABCB1 cells. YS-370 bound directly to P-gp, did not alter expression or subcellular localization of P-gp in SW620/AD300 cells, but increased the intracellular accumulation of paclitaxel. Furthermore, YS-370 stimulated the P-gp ATPase activity and had moderate inhibition against CYP3A4. Significantly, oral administration of YS-370 in combination with paclitaxel achieved much stronger antitumor activity in a xenograft model bearing SW620/Ad300 cells than either drug alone. Taken together, our data demonstrate that YS-370 is a promising P-gp inhibitor capable of overcoming MDR and represents a unique scaffold for the development of new P-gp inhibitors.

Herein, substituted imidazole-pyrazole hybrids (2a-2n) were prepared via a multi component reaction employing pyrazole-4-carbaldehydes (1a-1d), ammonium acetate, benzil and arylamines as reactants. All the new compounds were characterized through their spectral and elemental analyses. Further these compounds were tested against α-glucosidase enzyme. The compounds 2k, 2l and 2n possessed good inhibition potencies, however, compounds 2f (IC50 value: 25.19 ± 0.004 μM) and 2m (IC50 value: 33.62 ± 0.03 μM) were the most effective compounds of the series. Furthermore, molecular docking helped to understand the binding interactions of 2f and 2m with the understudy yeast's α-glucosidase enzyme.
