Static fermentation of amidepsine-producing fungus Humicola sp. FO-2942 led to the production of six new amidepsines, including a new type of glycosylated congener. Non-glycosylated amidepsine J inhibited both human diacylglycerol acyltransferases 1 (DGAT1) and DGAT2 with the same IC(50) value of 40 muM, whereas glycosylated amidepsines F to I showed very weak inhibitory activity against DGAT1 and DGAT2.
