Abstract

Drug-resistant tumor cells are rendered drug-sensitive by administering to the tumor cells a pump-affecting compound which suppresses the pumping action of P-glycoprotein on the tumor cells. In the case where the tumor cells have higher .beta.-glucuronidase activity than that of the surrounding tissues, the pump-affecting compound is in the form of a .beta.-D-glucuronide.
