DOx

2,5-Dimethoxyamphetamine (2,5-DMA), the base chemical structure of the DOx family.

4-Substituted-2,5-dimethoxyamphetamines (DOx) is a chemical class of substituted amphetamine derivatives featuring methoxy groups at the 2- and 5- positions of the phenyl ring, and a substituent such as alkyl or halogen at the 4- position of the phenyl ring.[1][2] They are 4-substituted derivatives of 2,5-dimethoxyamphetamine (2,5-DMA, DOH) and are structurally related to the naturally occurring phenethylamine psychedelic mescaline.

The most well-known DOx drugs are DOM, DOI, DOB, DOET, and DOC.[3] DOI is widely used in scientific research.[2][4] DOM has been used as a recreational drug, while DOET was an experimental pharmaceutical drug.[5]

Most compounds of this class are potent and long-lasting psychedelic drugs, and act as selective 5-HT2A, 5-HT2B, and 5-HT2C receptor agonists.[6][7] A few bulkier derivatives such as DOAM have similarly high affinity for 5-HT2 receptors but have reduced activational efficacy and do not produce psychedelic effects.[2][6]

DOI has been found to have extraordinarily potent anti-inflammatory effects.[8][9][10] These properties are not shared by all other related drugs and appear to be mediated by functionally selective serotonin 5-HT2A receptor activation.[9][11] The anti-inflammatory effects of DOI and related drugs may have medical applications.[8][9]
