Description | AS-186b, also known as purpactin a or vermixocin b, belongs to the class of organic compounds known as diarylethers. These are organic compounds containing the dialkyl ether functional group, with the formula ROR', where R and R' are aryl groups. AS-186b 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. Purpactin A is found in Penicillium, Penicillium asperosporum, Talaromyces purpureogenus, Penicillium simplicissimum, Pseudopenicillium megasporum and Talaromyces flavus. It was first documented in 1991 (PMID: 2010354). Based on a literature review a small amount of articles have been published on AS-186b (PMID: 8119857) (PMID: 17390588) (PMID: 1750931) (PMID: 2010355). |
