Hazard
Toxic; nervous system effects.
Biological Activity
norharmane acts as a co-mutagen. norharmane is a natural β-carboline first isolated from plants of the zygophyllaceae family. it is a heterocyclic amine (hca) that may also be found in fried meats, tobacco smoke, and coffee. harman and norharmane are aminocarbolines known as “co-mutagens” because they do not show mutagenicity to salmonella serovar typhimurium [1][2][3].norharmane acts as a co-mutagen. norharmane is widely distributed in our environment. it was not mutagenic to salmonella typhimurium ta98 and ta100 either with or without s9 mix, but became mutagenic to s.typhimurium ta98 with s9 mix when non-mutagenic aromatic amines like aniline or o- or m-toluidine are added. also, norharmane and aromatic amines induced the formation of dna adduct in s.typhimurium ta98 [3].harman and norharmane with concentrations of 0.275 um and 0.9 um respectively might inhibited mao-a and mao-b. in adult male rats, a novel cocktail of cigarette smoke constituents, containing five minor alkaloids (nornicotine, cotinine, myosmine, anatabine, and anabasine), two β-carbolines (harman and norharmane), and acetaldehyde, did not significantly enhance nicotine self-administration [2].
Biochem/physiol Actions
Inhibitor of indoleamine 2,3-dioxygenase (IDO).
Safety Profile
Poison by intravenous route.Experimental reproductive effects. Human mutation datareported. When heated to decomposition it emits toxicfumes of NOx.
