Abstract

Ganoderic acid R (GA-R) possessed significant cytotoxicity on a multidrug resistance (MDR) tumor cell line (KB-A-1/Dox) and a sensitive tumor cell line (KB-A-1). The results indicated that the inhibition effect of the GA-R was due to the induction of apoptosis. The use of GA-R in vitro resulted in a restoration response of the KB-A-1/Dox cells to the anti-tumor drug doxorubicin by stimulating the drug accumulation within the cells. The index of MDR reversion of GA-R was about 22 folds. The findings show that the ganoderma triterpene may be good candidates for anti-tumor and anti MDR chemotherapy.
