Arylcyclohexylamines are a category of substances to which the anesthetic ketamine belongs. The arylcyclohexylamines have been reported to act as antagonists of the N-methyl-d-aspartate (NMDA) receptor. An analog of ketamine, 2-(ethylamino)-2-(3-methoxyphenyl)-cyclohexanone (methoxetamine; MXE), has been controlled as a narcotic in Japan and overdoses of MXE have been reported to cause health problems. In recent years, MXE derivatives have beendetected in illegal products in Japan. In this study, we describe the identification of three MXE derivatives, 2-(3-methoxyphenyl)-2-(propylamino)cyclohexan-1-one (methoxpropamine; MXPr), 2-(isopropylamino)-2-(3-methoxyphenyl)cyclohexan-1-one (methoxisopropamine; MXiPr) and 2-(3-methoxyphenyl)-2-(propylamino)cyclohexan-1-one (deoxymethoxetamine; DMXE), from illegal products.
