NM-2-AI exhibits pronounced pharmacological actions, serving as a highly selective norepinephrine reuptake inhibitor and releasing agent in vitro settings.

NM-2AI demonstrates considerable binding affinities across various receptor sites, with notable values such as a 2.4 µM IC50 as a norepinephrine reuptake inhibitor, a 3.3 µM EC50 as a TAAR1 receptor agonist, a 0.49 µM Ki as an Alpha-2A adrenergic receptor agonist, and significant binding activity at the 5-HT1A (3.6 µM Ki) and 5-HT2A (5.4 µM Ki) receptors.



In-depth investigations into the metabolism of N-methyl-2-aminoindane (NM2AI) involved both in-silico and in-vivo approaches to identify critical metabolites for screening in various biological samples. Employing MetaSiteTM software, researchers initially predicted the in-silico metabolism of NM2AI. Subsequent verification involved the analysis of blood, urine, and hair samples from mice administered NM-2-AI.

The analysis via LC-HRMS revealed the presence of seven primary metabolites in the urine, confidently identified based on accurate masses and fragmentation patterns. These metabolites encompass 2-aminoindane (2AI), two forms of hydroxy-2-AI, and four variations of hydroxy-NM-2-AI. Notably, one of the hydroxy-NM-2-AI and one of the hydroxy-2-AI metabolites also underwent conjugation. Furthermore, NM-2-AI and 2-AI were detected in both hair and blood samples through LC-HRMS analysis.
