Abstract
A series of novel tetrahydroisoquinoline derivatives (7a-b and 8a-j) were synthesized by using N – cyanoguanyl as a spacer, and their multidrug resistance reversal activities against K562/A02 cell line in vitro were evaluated by MTT method. It was found that 7a and 8b showed more potent multidrug resistance reversal activities than verapamil.
