title: Actinotetraoses I-K: tetrasaccharide metabolites produced by an insect-derived actinobacteria, Amycolatopsis sp. HCa1.
abstract: An isolate of rare actinobacteria strain Amycolatopsis sp. HCa1 obtained from the gut of grasshopper produced seven different metabolites in vitro. The metabolites isolated from its mycelia cakes were characterized by NMR and MS analyses. Actinotetraose hexatiglate (or tigloside; 1) with nonreducing glucotetraose skeleton was isolated as a major constituent; three new tetrasaccharide derivatives actinotetraoses I-K (2-4, resp.) and three known actinotetraoses A-C (5-7, resp.) were also isolated.
