KS-176 (CAT: I001008) is a potent and selective inhibitor of the breast cancer resistance protein (BCRP), which is a multidrug transporter involved in drug efflux from cells. BCRP plays a crucial role in drug resistance by pumping various anticancer drugs out of cancer cells, leading to reduced effectiveness of chemotherapy. KS-176’s inhibitory action on BCRP can potentially enhance the intracellular concentration of chemotherapeutic agents, thereby overcoming drug resistance and improving the therapeutic outcomes of anticancer treatments.
