They can improve the cytotoxic of ADR to cancer cells by 5～10 folds under concentration of 10% cancer cell growth inhibitory rate. Peimine and Peiminine not only feather typical character of modifier of MDR, but also differ from other moldifiers such as Calcium channel blocker, Cyclosporines in chemical structure, they belong to cevine groups alkaloid, a subgroup of C-Nor-D-homosteroid alkaloid.
