Description

Precocene I, also known as pricocene I, belongs to the class of organic compounds known as precocenes. These are aromatic heteropolycyclic compounds that contain a 2,2-dimethyl-1-benzopyran moiety, which carries a methoxy group at the ring 7-position. Precocene I 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. Precocene 1 is found in Ageratum conyzoides, Ageratum houstonianum, Artemisia capillaris and Bidens pilosa. Precocene 1 was first documented in 1986 (PMID: 3797775). Based on a literature review a small amount of articles have been published on Precocene I (PMID: 11705333) (PMID: 17262477) (PMID: 21741958).
