2,5-Dimethoxy-4-fluoroamphetamine

2,5-Dimethoxy-4-fluoroamphetamine (DOF) is a serotonin receptor modulator of the phenethylamine, amphetamine, and DOx families.

Effects

Alexander Shulgin briefly describes DOF in his book PiHKAL:

DOF showed some stimulating effects in humans, but no psychedelic activity, after three doses of 6 mg spaced by one hour. Researcher Daniel Trachsel further suspected that the molar refraction of the important 4-substituent in DOF and 2C-F may be too low to activate the serotonin 5-HT_2A receptor sufficiently to produce psychedelic effects. DOF more closely mimics the effects of the 4-unsubstituted 2,5-dimethoxyamphetamine than the effects of DOC, DOB, and DOI.

Pharmacology

The receptor and transporter interactions of DOF have been characterized. As with other DOx drugs, it shows affinity for the serotonin 5-HT₂ receptors and acts as a partial to full agonist of the serotonin 5-HT_2A and 5-HT_2B receptors. However, it shows much lower affinity for the serotonin 5-HT₂ receptors than many other DOx drugs and a much lower degree of selectivity for the serotonin 5-HT_2A receptor over the serotonin 5-HT_1A receptor. On the other hand, the activational potencies of DOF at the serotonin 5-HT_2A and 5-HT_2B receptors was similar to those of DOB. The drug lacks significant affinity for the monoamine transporters (MATs), the human trace amine-associated receptor 1 (TAAR1), and various other receptors.
