Using matrine (1) as the lead compound, a series of new 14-(N-substituted-2-pyrrolemethylene) matrine and 14-(N-substituted-indolemethylene) matrine derivatives was designed and synthesized for their potential application as anticancer agents. The structure of these compounds was characterized by 1H NMR, 13C NMR and ESI-MS spectral analyses. The target compounds were evaluated for their in vitro cytotoxicity
