Bassianin is a fungal metabolite that has been found inBeauveria.^1,2It 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.¹Bassianin is cytotoxic to Sf9 and Sf21 insect cells with 50% cytotoxic concentration (CC₅₀) values of 4.91 and 12.12 µM, respectively.²
