DescriptionVenturamide A belongs to the class of organic compounds known as macrolactams. These are cyclic amides of amino carboxylic acids, having a 1-azacycloalkan-2-one structure, or analogues having unsaturation or heteroatoms replacing one or more carbon atoms of the ring. They are nitrogen analogues (the a nitrogen atom replacing the o atom of the cyclic carboxylic acid group ) of the naturally occurring macrolides. Venturamide A is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Venturamide A is found in Oscillataria sp. and Oscillatoria sp.. Venturamide A was first documented in 2007 (PMID: 17328572). Based on a literature review very few articles have been published on venturamide A.
