N-(3-aminopropyl)subergorgamide, a new alkaloid from the gorgonian Paraplexaura sp.

Abstract

A new alkaloid named N-(3-aminopropyl)subergorgamide (1), along with nine known nitrogen-containing compounds (2–10), was isolated from the organic extract of gorgonian Paraplexaura sp. collected from Zhanjiang in Naozhou Island, South China Sea. Their structures were established by detailed MS and NMR spectroscopic analyses, as well as by comparison with literature data.
