Isojaspisin: A novel styryl sulfate from a marine sponge, Jaspis sp., that inhibits hatching of sea urchin embryos

Abstract

A novel styryl sulfate, isojaspisin (1), was isolated from a marine sponge, Jaspis sp. The structure was determined to be sodium (Z)-5,6-dihydroxystryryl sulfate on the basis of its spectroscopic data. This sulfate inhibited hatching of sea urchin embryos with a minimum inhibitory concentration of 60 μM. © 1994.
