The cytotoxicity and the selective antiprotozoal activity of some Strychnos alkaloids, namely strychnopentamine (SP) and usambarensine (US) (7) led us to analyze and compare their effects with emetine (EM) by using mouse B16 melanoma cells cultivated in vitro. We observed by cytological analysis and
