Used in research for its potential antitumor and anticancer properties, particularly in studies related to drug resistance in cancer cells. Shows activity as a multidrug resistance reversal agent, enhancing the effectiveness of certain chemotherapy drugs by inhibiting efflux pumps in cancer cell membranes. Investigated for use in combination therapies to improve intracellular concentration of anticancer agents. Also employed as a reference compound in structure-activity relationship studies of taxane derivatives.
