Abstract:
:From our modulator library an interesting inhibitor of breast cancer resistance protein (BCRP) was identified. Due to its high inhibitory potency, this compound may serve as a promising novel lead for the design of new and potent modulators. This adds a new structural class to the few known highly active BCRP inhibitors.
