DOx

2,5-Dimethoxyamphetamine (2,5-DMA), the base 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] Most compounds of this class are potent and long-lasting psychedelic drugs, and act as highly selective 5-HT_2A, 5-HT_2B, and 5-HT_2C receptor partial agonists. A few bulkier derivatives such as DOAM have similarly high binding affinity for 5-HT₂ receptors but instead act as antagonists, and so do not produce psychedelic effects though they retain amphetamine-like stimulant effects.
