Common Name7-Methyl-2-morpholino-9-(1-(phenylamino)ethyl)-4H-pyrido[1,2-a]pyrimidin-4-one
Description7-Methyl-2-morpholino-9-(1-(phenylamino)ethyl)-4H-pyrido[1,2-a]pyrimidin-4-one, also known as TGX 221 or TGX221 CPD, belongs to the class of organic compounds known as pyridopyrimidines. Pyridopyrimidines are compounds containing a pyridopyrimidine, which consists of a pyridine fused to a pyrimidine. Pyridine is 6-membered ring consisting of five carbon atoms and a nitrogen atom. Pyrimidine is a 6-membered ring consisting of four carbon atoms and two nitrogen centers at the 1- and 3- ring positions. Based on a literature review very few articles have been published on 7-Methyl-2-morpholino-9-(1-(phenylamino)ethyl)-4H-pyrido[1,2-a]pyrimidin-4-one. This compound has been identified in human blood as reported by (PMID: 31557052 ). 7-methyl-2-morpholino-9-(1-(phenylamino)ethyl)-4h-pyrido[1,2-a]pyrimidin-4-one is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 7-Methyl-2-morpholino-9-(1-(phenylamino)ethyl)-4H-pyrido[1,2-a]pyrimidin-4-one 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.
