Common Name(+-)-(4Ar*,10R*,10aS*)-8-Chloro-1,2,3,4,10,10a-hexahydro-2-methyl-4a,10-(iminoethano)-4aH-(1)benzopyrano(3,2-c)pyridin-12-one
DescriptionLortalamine belongs to the class of organic compounds known as naphthyridines. Naphthyridines are compounds containing a naphthyridine moiety, a naphthalene in which a carbon atom has been replaced by a nitrogen in each of the two rings. The naphthyridine skeleton can also be described as an assembly two fused pyridine rings, which do not share their nitrogen atom. Lortalamine is a very strong basic compound (based on its pKa). Lortalamine was under development for clinical use but was shelved, likely due to the finding that it produced ocular toxicity in animals. Lortalamine (LM-1404) is an antidepressant which was synthesized in the early 1980s. It has been used to label the norepinephrine transporter in positron emission tomography studies. It acts as a potent and highly selective norepinephrine reuptake inhibitor. This compound has been identified in human blood as reported by (PMID: 31557052 ). (+-)-(4ar*,10r*,10as*)-8-chloro-1,2,3,4,10,10a-hexahydro-2-methyl-4a,10-(iminoethano)-4ah-(1)benzopyrano(3,2-c)pyridin-12-one is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically (+-)-(4Ar*,10R*,10aS*)-8-Chloro-1,2,3,4,10,10a-hexahydro-2-methyl-4a,10-(iminoethano)-4aH-(1)benzopyrano(3,2-c)pyridin-12-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.
