O-Methylnordehydrobufotenine, also known as O-methyldehydrobufotenidine or as 6-methoxy-5-methyl-1,2,3,4,5-tetrahydropyrrolo[4,3,2-d,e]-quinoline, is a tricyclic cyclized tryptamine and analogue of 5-MeO-DMT and bufotenine.[1][2][3][4] It produces hallucinogen-like effects in monkeys and rodents.[1][3][4] However, although more potent than mescaline, O-methylnordehydrobufotenine was far less active than its open-chain analogue 5-MeO-DMT.[4] The drug is not known to have been tested in humans.[3] O-Methylnordehydrobufotenine was first described in the scientific literature by 1969.[1][3][4]

In addition, Lee, et al,(31) have prepared O-methyl nordehydrobufotenin 6 and found it to be active. Although it does not satisfy correlate 1 of Chothia and Pauling, it has the required aromatic system and point of electron density at the 4 indole position.

Despite not actually ever being proven to be a hallucinogen in either animals or humans, this is interesting as, while it remains unreported as a naturally occurring alkaloid, this molecule is a simple rearrangement product of dehydrobufotenine. It suggests that it too may be physiologically active albeit possibly moderately toxic.

Journal of Medicinal Chemistry. 12 (2): 321–322. doi:10.1021/jm00302a030. PMID 4977410. Because of the high CNS activity shown by N,N-dimethyl-5-methoxytryptamine, the synthesis of the structurally related tricyclic indole, O-methylnordehydrobufotenine (6-methoxy-5-methyl-1,3,4,5-tetrahydropyrrolo[4,3,2-d,e]quinoline, IIc), was undertaken. [...] Pharmacologic activity was determined in squirrel monkeys trained in the Wisconsin General Test Apparatus [...] The median effective dose (ED50) of IIc that disrupted the ability to discriminate between disks of different sizes was 33.8 μmoles/kg.12 In this test, the O-methylnordehydrobufotenine (IIc) is approximately twice as active as mescaline (ED50 71.0 μmoles/kg),11 but is much less active than its open-chain analog, N,N-dimethyl-5-methoxytryptamine, which from published data5,8 can be estimated to be much more than 30 times as active a hallucinogen as mescaline. When injected subcutaneously into NIH general purpose white mice, IIc at 20 mg/kg causes only slight overt changes (reduction in spontaneous activity) while N,N-dimethyl-5-methoxytryptamine at 10 mg/kg causes profound effects. At this dosage the mice lose the ability to move normally and engage in locomotor activity with legs extended laterally.
