beta-Carboline, also known as norharmane, is an organic amine and is the prototype of a class of compounds known as beta-carbolines. beta-Carbolines are compounds containing a 9H-pyrido[3,4-b]indole moiety. beta-Carboline is a very strong basic compound (based on its pKa). beta-Carboline alkaloids are widely distributed in plants and animals and many are inverse agonists of the GABA-A receptor complex (PMID: 17334612). Other biological activities demonstrated by these compounds include intercalation; inhibition of CDK, topoisomerase, and monoamine oxidase; and interaction with 5-hydroxy serotonin receptors. These compounds have also exhibited sedative, anxiolytic, hypnotic, anticonvulsant, antitumor, antiviral, antiparasitic, and antimicrobial activities (PMID: 17305548).
