YHO-13177 is a potent and specific inhibitor ofBCRP; potentiated the cytotoxicity of SN-38 incancercells and no effect on P-glycoprotein–mediated paclitaxel resistance in MDR1-transduced human leukemia K562 cells. IC50 value: Target:BCRP inhibitorin vitro: YHO-13177 potentiated the cytotoxicity of SN-38, mitoxantrone, and topotecan in both BCRP-transduced human coloncancerHCT116 (HCT116/BCRP) cells and SN-38–resistant human lungcancerA549 (A549/SN4) cells that expressBCRP, but had little effect in the parental cells. In addition, YHO-13177 potentiated the cytotoxicity of SN-38 in human lungcancerNCI-H460 and NCI-H23, myeloma RPMI-8226, and pancreaticcancerAsPC-1 cells that intrinsically expressedBCRP. In contrast, it had no effect on P-glycoprotein–mediated paclitaxel resistance in MDR1-transduced human leukemia K562 cells and multidrug resistance-related protein 1–mediated doxorubicin resistance in MRP1-transfected human epidermoidcancerKB-3-1 cells. YHO-13177 increased the intracellular accumulation of Hoechst 33342, a substrate ofBCRP, at 30 minutes and partially suppressed the expression ofBCRPprotein at more than 24 hours after its treatment in both HCT116/BCRP and A549/SN4 cells [1]. in vivo: In mice, YHO-13351 was rapidly converted into YHO-13177 after its oral or intravenous administration. Coadministration of irinotecan with YHO-13351 significantly increased the survival time of mice inoculated with BCRP-transduced murine leukemia P388 cells and suppressed the tumor growth in an HCT116/BCRP xenograft model, whereas irinotecan alone had little effect in these tumor models [1].
