| Description | methyl 16-methyl-17-oxa-3,13-diazapentacyclo[11.8.0.0²,¹⁰.0⁴,⁹.0¹⁵,²⁰]henicosa-2(10),4,6,8,18-pentaene-19-carboxylate belongs to the class of organic compounds known as yohimbine alkaloids. These are alkaloids containing the pentacyclic yohimban skeleton. The Yohimbinoid alkaloids contain a carbocyclic ring E arising through C-17 to C-18 bond formation in a corynantheine precursor. Based on a literature review very few articles have been published on methyl 16-methyl-17-oxa-3,13-diazapentacyclo[11.8.0.0²,¹⁰.0⁴,⁹.0¹⁵,²⁰]henicosa-2(10),4,6,8,18-pentaene-19-carboxylate. This compound has been identified in human blood as reported by (PMID: 31557052 ). Ajmalicine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Ajmalicine 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. |
