Oosporein is a mycotoxin that has been found inBeauveriaand has diverse biological activities.1,2It is cytotoxic to Sf9 and Sf21 insect cells with 50% cytotoxic concentration (CC50) values of 4.23 and 10.43 μM, respectively.3Oosporin induces lethality in day-old cockerels (LD50= 6.12 mg/kg).4It inhibits Na+/K+-, Ca2+-, and Mg2+-ATPase activities by 27, 52, and 100%, respectively, in equine erythrocyte ghosts when used at a concentration of 200 μg/ml.2Oosporein inhibits herpes simplex 1 (HSV-1), but not HeLa cell orE. coli, DNA polymerase (IC50s = 75, 610, and >700 μM, respectively).5It is active against the bacteriumS. pneumoniae(MIC = 32 μg/ml) and the plant pathogenic fungusP. infestans(MIC = 16 μM).1,6
