Pyrrolidinylethylindoles

Pyr-T, also known as '''N,N-tetramethylenetryptamine or as 3-(2-pyrrolidinoethyl)indole', is a lesser-known serotonin receptor modulator of the tryptamine and pyrrolidinylethylindole families. It is the cyclized derivative of diethyltryptamine (DET) in which the N,N''-diethyl groups have been fused into a pyrrolidine ring.

4-HO-pyr-T, also known as '4-hydroxy-N,N-tetramethylenetryptamine', is a serotonin receptor modulator of the tryptamine, 4-hydroxytryptamine, and pyrrolidinylethylindole families. It is the 4-hydroxyl analogue of pyr-T and the analogue of psilocin (4-HO-DMT) and 4-HO-DET in which the N,N-dialkyl moiety has been cyclized into a pyrrolidine ring.

5-MeO-pyr-T, also known as '5-methoxy-N,N-tetramethylenetryptamine or as 5-methoxy-3-(2-pyrrolidinoethyl)indole', is a serotonin receptor modulator and psychedelic drug of the tryptamine, 5-methoxytryptamine, and pyrrolidinylethylindole families. It is the 5-methoxy analogue of pyr-T and the derivative of 5-MeO-DMT and 5-MeO-DET in which their N,N-dialkyl groups have been cyclized into a pyrrolidine ring.
