Ansacarbamitocin B and D isolated from Amycolatopsis sp. FID23-7-18 associated to the fungus-growing ant Mycetomoellerius mikromelanos.
Ansacarbamitocin B (1) and D (2) were identified as major compounds from ISP-2 agar culture of Amycolatopsis sp. FID23-7-18, isolated from the exoskeleton of Mycetomoellerius mikromelanos worker ants. Elucidation of their structures was accomplished using 1D and 2D NMR spectroscopy and MS data. Compounds 1 and 2 showed...
