Metachromins R--T, new sesquiterpenoids from marine sponge Spongia sp

Chem Pharm Bull (Tokyo). 2007 Dec;55(12):1731-3. doi: 10.1248/cpb.55.1731.

Abstract

Three new sesquiterpenoids, metachromins R--T (1--3), have been isolated from an Okinawan marine sponge Spongia sp. The structures and stereochemistry of 1--3 were elucidated on the basis of the spectroscopic data. Metachromins S (2) and T (3) showed modest cytotoxicity.
