An alkaloid with diverse biological activities
Lycorine is an alkaloid that has been found in Amaryllidaceae and has diverse biological activities.1,2,3,4 It is active against P. falciparum (IC50 = 1.026 ?g/ml).1 Lycorine inhibits severe acute respiratory syndrome coronavirus (SARS-CoV) viral infection in Vero cells (EC50 = 15.7 ?M).2 It inhibits migration of A549 non-small cell lung cancer (NSCLC) and U373 MG glioblastoma cells when used at a concentration of 5 ?M.3 Lycorine (0.4 mg/kg) increases survival and reduces virus-induced paralysis in a mouse model of enterovirus 71 infection.4
