Matrine and oxymatrine,two kinds of alkaloid from Radix Sophorae Flavescentis,have various pharmacological activities.In recent years,much more attention has been paid to their anti-tumor potentials and mechanisms.Matrine and oxymatrine inhibit cancer cells proliferation,induce cell cycle arrest,elicit apoptosis,induce differentiation,restrain agiogenesis and inhibit invasion and metastasis.Furthermore,matrine and oxymatrine could reverse the multi-drug resistance and enhance the anti-cancer potential when combined treatment with other chemotherapeutic drugs.This article summarized the research progress in the anti-tumor effects and mechanisms of these two compounds in order to provide clues and references for the further study of them.
