Crotokilwaepoxide C

Description

Crotokilwaepoxide C belongs to the class of organic compounds known as prostaglandins and related compounds. These are unsaturated carboxylic acids consisting of a 20 carbon skeleton that also contains a five member ring, and are based upon the fatty acid arachidonic acid. Crotokilwaepoxide C was first documented in 2023 (PMID: 36749598). Based on a literature review very few articles have been published on Crotokilwaepoxide C.
