Dimemebfe


Dimemebfe, also known as 5-methoxy-N,''N''-dimethyl-3-benzofuran or as 1-oxa-5-MeO-DMT, is a psychedelic drug of the benzofuran family related to the psychedelic tryptamine 5-MeO-DMT. It is the analogue and bioisostere of 5-MeO-DMT in which the nitrogen atom of the indole ring has been replaced with an oxygen atom, making dimemebfe a benzofuran rather than tryptamine derivative. The drug has been encountered as a novel designer drug.

Pharmacology

Pharmacodynamics

Dimemebfe acts as an agonist of the serotonin 5-HT1A and 5-HT2 family of serotonin receptors. It is several times less potent as a receptor agonist">receptor (biochemistry)">receptor agonist than 5-MeO-DMT and with relatively more activity at the serotonin 5-HT1A receptor, but still shows strongest actions at the 5-HT2 family of receptors.
