Penasulfate A, a New alpha-Glucosidase Inhibitor from a Marine SpongePenares sp.

摘要

A new alpha-glucosidase inhibitor, penasulfate A, has been isolated from a marine sponge Penares sp.(1) Its structure was elucidated by spectral and chemical methods to be a scalemic mixture of methyl pipecolates acylated with a novel sulfated fatty acid.
