Common Name1-(5-Fluoropentyl)-1H-indole-3-carboxylic acid 8-quinolinyl ester
Description1-(5-Fluoropentyl)-1H-indole-3-carboxylic acid 8-quinolinyl ester, also known as 5F-PB-22 or 5-fluoro-PB-22, belongs to the class of organic compounds known as indolecarboxylic acids and derivatives. Indolecarboxylic acids and derivatives are compounds containing a carboxylic acid group (or a derivative thereof) linked to an indole. Based on a literature review very few articles have been published on 1-(5-Fluoropentyl)-1H-indole-3-carboxylic acid 8-quinolinyl ester. This compound has been identified in human blood as reported by (PMID: 31557052 ). 1-(5-fluoropentyl)-1h-indole-3-carboxylic acid 8-quinolinyl ester is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 1-(5-Fluoropentyl)-1H-indole-3-carboxylic acid 8-quinolinyl ester 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.
