RU-28253, also known as5-MeO-THPI, is anon-selectiveserotonin receptor agonist of thetryptamine,5-methoxytryptamine, andtetrahydropyridinylindole families.[1][2][3][4] It is a tetrahydropyridylindole and aconformationally constrainedanalogue of5-MeO-DMT.[2][3]

The drug shows highaffinity for theserotonin5-HT1A receptor (Ki = 5.7 nM) and lower affinity for the serotonin5-HT2A receptor (Ki = 230 nM).[2] Its affinities for these receptors were higher than those ofdimethyltryptamine (DMT).[2] RU-28253 is described as apotent agonist of the serotonin5-HT1 and5-HT2 receptors,[5] including of the serotonin5-HT1B receptor,[6] and is also an agonist of the serotonin5-HT4 receptor.[3][7]

RU-28253 was first described in thescientific literature by 1983.[8][9][2]
