ABCB1-IN-2

ABCB1-IN-2 (compound 16q) is a functional inhibitor that directly binds and stabilizes the ABCB1 protein structure without altering its expression and subcellular localization. This compound enhances the sensitivity of MCF-7/ADR cells to paclitaxel (PTX) by increasing PTX accumulation and inhibiting the ABCB1-mediated accumulation and excretion of luciferin Rh123. As a potent ABCB1-mediated multidrug resistance (MDR) reversal agent, ABCB1-IN-2 effectively reverses MDR.
