Description | Ketanserin belongs to the class of organic compounds known as alkyl-phenylketones. These are aromatic compounds containing a ketone substituted by one alkyl group, and a phenyl group. Ketanserin is a very strong basic compound (based on its pKa). It was discovered at Janssen Pharmaceutica in 1980. It has been used in cardiac surgery. The same research team found no significant correlation with age in their homogenate binding study. It has also been found to block the vesicular monoamine transporter 2 (VMAT2). With tritium (3H) radioactively labeled ketanserin is used as a radioligand for serotonin 5-HT2 receptors, e.g. in receptor binding assays and autoradiography. Ketanserin is a high-affinity non-selective antagonist of 5-HT2 receptors in rodents, with Ki values of 2–3 nM for the 5-HT2A receptor and 28 nM for the 5-HT2C receptor). However, due to the significant adverse effect burden, the authors concluded that ketanserin's utility for this indication is likely unbeneficial. Ketanserin (INN, USAN, BAN) (brand name Sufrexal; former developmental code name R41468) is a drug used clinically as an antihypertensive agent and in scientific research to study the serotonin system; specifically, the 5-HT2 receptor family. This compound has been identified in human blood as reported by (PMID: 31557052 ). Ketanserin is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Ketanserin 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. |
