Descripción
Sumario:Seven new marine 11-acetoxy-9,11-secosterols, pinnisterols D–J (1–7), with a 1,4-quinone moiety, were discovered from the gorgonian coral Pinnigorgia sp. In this study, the structures of secosterols 1–7 were revealed by spectroscopic analysis. Bioactivity study showed that secosterol 1 treatment inhibited cell viability in a hepatic stellate cell line, HSC-T6, with an IC(50) value of 3.93 μM; and secosterols 2, 5, and 7 reduced elastase enzyme release, and 3, 5, and 7 decreased the production of superoxide anions from human neutrophils.
