Callyspongynic acid, a polyacetylenic acid which inhibits alpha-glucosidase, from the marine sponge Callyspongia truncata.
A new polyacetylenic acid, callyspongynic acid (1), was isolated as an alpha-glucosidase inhibitor from the marine sponge Callyspongia truncata. Its structure was determined by spectroscopic and chemical methods.
