DescriptionEpothilone a, also known as epo a, belongs to the class of organic compounds known as epothilones and analogues. These are macrolides consisting of a 16-member lactone ring conjugated at the carbon 16 with a 1-(2-methyl-1,3-thiazol-4-yl)prop-1-en-2-yl group. Some epothilone analogues containing a lactam ring instead of the lactone ring. Thus, epothilone a is considered to be a macrolide. Epothilone a is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Epothilone A is found in Sorangium cellulosum. Epothilone A was first documented in 2000 (PMID: 11133086). Based on a literature review very few articles have been published on Epothilone a (PMID: 18271516).
