5-HO-DPT, also known as 5-hydroxy-N,N-dipropyltryptamine, as well as N,N-dipropylserotonin (DiPS or NDPS), is a serotonin receptor modulator of the tryptamine and 5-hydroxytryptamine families.[1] It is the N,N-dipropyl derivative of serotonin (5-hydroxytryptamine; 5-HT).[1]

The drug shows affinity for the serotonin 5-HT1A receptor (Ki = 7.1 nM), the serotonin 5-HT1B receptor (Ki = 4,300 nM), and the serotonin 5-HT2 receptor (Ki = 1.0–450 nM).[1] 5-HO-DPT was not tested itself, but its O-methyl ether 5-MeO-DPT fully substituted for the psychedelic drug DOM in rodent drug discrimination tests and partially substituted for 8-OH-DPAT in these tests followed by behavioral disruption at higher doses.[1] 5-Hydroxytryptamines like bufotenin (5-HO-DMT) are known to be hydrophilic and peripherally selective, in turn resulting in difficulty crossing the blood–brain barrier and exerting central effects,[1] but 5-HO-DPT is notable in having much greater lipophilicity in comparison to bufotenin owing to its propyl groups (predicted log P = 3.0 and 1.2, respectively).[2][3]

5-HO-DPT was first described in the scientific literature by Richard Glennon and colleagues by 1988.[1]
