Briarenols Q-T: Briaranes from A Cultured Octocoral Briareum stechei (Kükenthal, 1908)

Mar Drugs. 2020 Jul 24;18(8):383. doi: 10.3390/md18080383.

Abstract

Our continuous chemical study of a cultured octocoral Briareum stechei led to the isolation of four new briarane diterpenoids, briarenols Q-T (1-4). The structures of new metabolites 1-4 were established by spectroscopic methods, and compounds 3 and 4 were found to inhibit the generation of inducible nitric oxide synthase (iNOS) from RAW 264.7 stimulated by lipopolysaccharides (LPS).

Keywords: Briareum stechei; COX-2; briarane; briarenol; iNOS.
