Reversing Effect of Agosterol A, a Spongean Sterol Acetate, on Multidrug Resistance in Human Carcinoma Cells
1 Aug 2001
Abstract excerpt
The effect of agosterol A, a novel polyhydroxylated sterol acetate isolated from a marine sponge, on P-glycoprotein (P-gp)-mediated multidrug-resistant cells (KB-C2) and the multidrug resistance associated protein (MRP1)-mediated multidrug-resistant cells (KB-CV60) was examined. Agosterol A reversed the resistance to colchicine in KB-C2 cells and also the resistance to vincristine in KB-CV60 cells at 3 to 10...
