Description6-{[2-carboxy-1-hydroxy-2-(thiophen-3-yl)ethylidene]amino}-6-methoxy-3,3-dimethyl-7-oxo-4-thia-1-azabicyclo[3.2.0]heptane-2-carboxylic acid belongs to the class of organic compounds known as penicillins. These are organic compounds containing the penicillin core structure, which is structurally characterized by a penam ring bearing two methyl groups at position 2, and an amide group at position 6 [starting from the sulfur atom at position 1]. Based on a literature review very few articles have been published on 6-{[2-carboxy-1-hydroxy-2-(thiophen-3-yl)ethylidene]amino}-6-methoxy-3,3-dimethyl-7-oxo-4-thia-1-azabicyclo[3.2.0]heptane-2-carboxylic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). Temocillin is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Temocillin is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
