Description8-{4-[4-(quinolin-2-yl)piperazin-1-yl]butyl}-8-azaspiro[4.5]decane-7,9-dione belongs to the class of organic compounds known as pyridinylpiperazines. Pyridinylpiperazines are compounds containing a pyridinylpiperazine skeleton, which consists of a pyridine linked (not fused) to a piperazine by a bond by a single bond that is not part of a ring. Based on a literature review very few articles have been published on 8-{4-[4-(quinolin-2-yl)piperazin-1-yl]butyl}-8-azaspiro[4.5]decane-7,9-dione. This compound has been identified in human blood as reported by (PMID: 31557052 ). Kaspar is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Kaspar 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.
