10432484-2	1999	There is now converging evidence from biochemical, electrophysiological, and behavioral studies that the two major classes of psychedelic hallucinogens, the indoleamines (e.g., LSD) and the phenethylamines (e.g., mescaline), have a common site of action as partial agonists at 5-HT2A and other 5-HT2 receptors in the central nervous system.	Phenethylamines	190-205	5-hydroxytryptamine receptor 2A	Homo sapiens	277-283	
31849671-12	2019	Conclusion: As seen with earlier series investigated, the 4-alkyloxy-substituted 2,5-dimethoxyamphetamines and phenethylamines share some trends with the many other phenethylamine pharmacophore containing compounds, such as when increasing the size of the 4-substituent and increasing the lipophilicity, the affinities at the 5-HT2A/C subtype also increase, and only weak 5-HT2A/C subtype selectivities were achieved.
