Common NameHydroxyhomo Sildenafil
Description5-(2-ethoxy-5-{[4-(2-hydroxyethyl)piperazin-1-yl]sulfonyl}phenyl)-1-methyl-3-propyl-1H,6H,7H-pyrazolo[4,3-d]pyrimidin-7-one belongs to the class of organic compounds known as benzenesulfonamides. These are organic compounds containing a sulfonamide group that is S-linked to a benzene ring. 5-(2-ethoxy-5-{[4-(2-hydroxyethyl)piperazin-1-yl]sulfonyl}phenyl)-1-methyl-3-propyl-1H,6H,7H-pyrazolo[4,3-d]pyrimidin-7-one is a very strong basic compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). Hydroxyhomo sildenafil is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Hydroxyhomo Sildenafil 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.
