Bassianin is a fungal metabolite that has been found in Beauveria.1,2 It inhibits Mg2+-, Ca2+-, and Na+/K+-ATPase activities in equine erythrocyte ghosts by 81, 58, and 23%, respectively, when used at a concentration of 200 µg/ml.1 Bassianin is cytotoxic to Sf9 and Sf21 insect cells with 50% cytotoxic concentration (CC50) values of 4.91 and 12.12 µM, respectively.2
