They have been isolated from diverse marine organisms and all of them feature a 3,4-diarylpyrrole 2-carboxylic acid ester or amide moiety. This article provides an overview of recent literatures on lamellarins and related pyrrole-derived alkaloids, including their isolation, total synthesis, biological and structure activity relationship （SAR） studies.展开更多
