Substituted isotryptamine Isotryptamine , the parent compound of the substituted isotryptamines and the simplest isotryptamine.Substituted isotryptamines , or simply isotryptamines , also known as 2-(1-indolyl)ethylamines , are a group of indoles closely related to the tryptamines but with the ethyl amine side chain located at the 1 position of the indole ring system rather than at the 3 position as in tryptamines. Hence, they are positional isomers of tryptamines.
A variety of isotryptamines have been studied and described, including serotonergic psychedelics and psychoplastogens like 6-MeO-isoDMT ;[ 1] [ 2] hallucinogenic psychoplastogens like isoDMT , 5-MeO-isoDMT , and zalsupindole (DLX-001; AAZ-A-154);[ 3] [ 4] [ 5] [ 6] serotonin 5-HT2C receptor agonists like (S )-5,6-difluoro-isoAMT , Ro60-0175 ((S )-5-fluoro-6-chloro-isoAMT), and PNU-181731 ;[ 7] [ 8] [ 9] [ 10] [ 11] 5-HT6 receptor modulators ;[ 12] [ 13] [ 14] monoamine releasing agents and serotonin receptor agonists like isoAMT (PAL-569).[ 15] [ 16] [ 17]
JRT is the isotryptamine analogue of LSD and may be considered a cyclized isotryptamine.[ 18] [ 19]
