In the 1960's there was quite a bit of interest at a couple of pharmaceutical houses in the indole analogues of amphetamine. Both the alpha-methylated tryptamine (AMT) and the alpha-ethylated homologue (AET) were found to be effective monoamine oxidase inhibitors, and both were clinically studied as potential antidepressants. The ethyl compound became a commercial drug, offered by the Upjohn Company as Monase, but now is considered to be without medical use and is a Schedule I drug. It is interesting that this methyl compound, AMT was also a medically available antidepressant in the Soviet Union in the 1960's and was sold under the name of Indopan, in 5 and 10 milligram tablets.
