Product Description: Dofequidar (MS-209 free base) is an orally active quinoline compoundthat blocks P-glycoprotein (P-gp) and multidrug resistance-associated protein-1 (MDR-1). Dofequidar has highly potent reversing effect on multidrug-resistant tumor cells. Dofequidar competitively inhibits ABCB1/P-gp, ABCC1/MRP-1, blocks the efflux of chemotherapeutic agents, increases the drug concentration in cancer cells, and enhances the chemotherapeutic effect[1][2].
Applications: Cancer-programmed cell death
Formula: C30H31N3O3
