Glaucine (also known as 1,2,9,10-tetramethoxyaporphine, bromcholitin, glauvent, tusidil, and tussiglaucin) is an aporphine alkaloid found in several different plant species in the family Papaveraceae, such as Glaucium flavum,[1] Glaucium oxylobum, and Corydalis yanhusuo,[2][3] and in other plants such as Croton lechleri in the family Euphorbiaceae.[4]

It has bronchodilator, neuroleptic[5] and antiinflammatory effects, acting as a PDE4 inhibitor and calcium channel blocker,[6] and is used medically as an antitussive in some countries.[7] TLRs plays role in its anti inflammatory effects.[8] Glaucine may produce side effects such as sedation, fatigue, and a hallucinogenic effect characterised by colourful visual images,[9][10] and has been detected as a novel psychoactive drug.[11] In a 2019 publication,[12] the isomer (R)-glaucine is reported to be a positive allosteric modulator of the 5-HT2A receptor, which is also associated with the hallucinogenic effects of substances such as psilocybin and mescaline.
