Harman-d₃ 

Harman-d₃ is deuterium labeled Harmane. Harmane is an inhibitor that binds to benzodiazepine receptors (with an IC₅₀ value of 7 μM), has an IC₅₀ of 24 μM for muscarinic acetylcholine receptors (QNB), an IC₅₀ of 2.8 μM for opioid receptors, and IC₅₀ values of 163 and 101 μM for spironolactone and serotonin, respectively. Harmane is a selective monoamine oxidase inhibitor (with IC₅₀ values of 0.5 μM for MAO A and 5 μM for MAO B). Harman inhibits dopamine biosynthesis by decreasing tyrosine hydroxylase (TH) activity and enhancing levodopa (L-DOPA)-induced toxicity in PC12 cells. Harmane lowers blood pressure in rats through the I1 imidazoline receptor (I1 receptor) and has antidepressant, anxiolytic, anticonvulsant, and analgesic effects. Harmane enhances the mutagenicity induced by 2-acetylaminofluorene (AAF) ^{[1][2][3][4][5][6][7]}.
