Actinotetraose L, a new tetrasaccharide derivative isolated from the mycelia of Amycolatopsis sp. HCa1.


A new tetrasaccharide derivative, actinotetraose L (1), was isolated from the methanol extract of the mycelia of the grasshopper-associated rare actinobacterium Amycolatopsis sp. HCa1. The structure of the new compound was elucidated by a combination of 1D, 2D NMR (HMQC, HMBC, COSY, and NOESY), and HR-ESI-MS analyses as O-{3,4-di-O-[(E)-2-ethyl-2-butenoyl… (More)
