Pharmacology

Pharmacodynamics

The compound was assessed and found to inhibit prolactin secretion in rat pituitary glands in vitro at high concentrations, suggesting that it may possess weak dopamine receptor agonist activity.^[2]^[1] However, it was subsequently assessed in rats in vivo and, in contrast to LSD, was found to not significantly inhibit prolactin secretion.^[1] Other possible activities of 25D-NM-NDEAOP, such as serotonin receptor interactions and associated effects, were not evaluated or reported.^[1]^[2]^[3]

Chemistry

The compound is a PEA-NDEPA derivative and is similar in structure to other PEA-NDEPA compounds such as DOM-NDEPA and TMA-2-NDEPA, as well as DOB-NDEPA, DOI-NDEPA, and DOTFM-NDEPA.^[4] The latter three compounds have been predicted via QSAR modeling to be potent serotonin 5-HT_2A receptor agonists.^[4] A parent compound of 25D-NM-NEAOP is N-(3-diethylamino-3-oxopropyl)-N-methylphenethylamine (N-DEAOP-NMPEA or PEA-NM-NDEPA), which showed weak oxytocic activity in preclinical research.^[5]

History

25D-NDEAOP was first described in the scientific literature in 1974.^[2]^[1]

Journal of the American Pharmaceutical Association. 41 (12): 637–639. doi:10.1002/jps.3030411204. PMID 13022416. Six esters and amides of derivatives of β-alanine which are related to lysergic acid have been prepared and tested for oxytocic activity. None of these products possess a significant oxytocic activity. [...] The purpose of this investigation was to synthesize amides and also esters of compounds (II–V) which represent fragments of the lysergic acid molecule in the hope that some of these products might possess oxytocic activity. Various modified fragments of the lysergic acid molecule have been synthesized previously; it was claimed that some of the compounds are active oxytocics (1—7). [...] Pharmacologic data indicated that none of the esters or amides of compounds II—V which were prepared possess a significant oxytocic action when compared to the clinically used oxytocics. However, the diethylamide of N-methyl-N-[β′-(3-indolyl)-ethyl]-β-alanine (IIIc) appeared to have an oxytocic activity approximately ten times stronger than that of the diethylamide of N-methyl-N-(β′-phenethyl)-β-alanine (IIc).
