(what is this?) (verify)Oxaprotiline, also known as hydroxymaprotiline, is a psychoactive drug and research chemical of the tetracyclic chemical class. Though investigated as an antidepressant,[1] it was never developed and marketed for clinical use.

Chemistry
Oxaprotiline is a racemic compound composed of two isomers, R(-)- or levo- oxaprotiline (levoprotiline; CGP-12,103-A), and S(+)- or dextro- oxaprotiline (dextroprotiline; CGP-12,104-A). Both enantiomers are active, with the levo- form acting merely as an antihistamine and the dextro- form having a more expansive pharmacology (see below), but with both curiously still retaining antidepressant effects.[2]
Pharmacology
Dextroprotiline acts as a potent norepinephrine reuptake inhibitor[3][4] and H1 receptor antagonist,[5] as well as a very weak α1-adrenergic receptor antagonist.[6][3] It has negligible affinity for the serotonin transporter,[3] dopamine transporter, α2-adrenergic receptor,[6][3] and muscarinic acetylcholine receptors.[6] Whether it has any antagonistic effects on the 5-HT2 or D2 receptors like its relative maprotiline is unclear.
Levoprotiline acts as a selective H1 receptor antagonist, with no affinity for adrenaline, dopamine, muscarinic acetylcholine, or serotonin receptors, or any of the monoamine transporters.[5][3][4]
