Oligostatins, new antibiotics with amylase inhibitory activity. II. Structures of oligostatins C D and E.

Abstract
The structures of oligostatins C, D and E were studied spectrometrically and chemically. Oligostatins C, D and E are pseudo-penta, -hexa and -heptasaccharides with a nitrogen containing glycosidic bond. These antibiotics represent a new series of amylase inhibitors of the saturated basic oligosaccharide.
