High Resolution Image Download MS PowerPoint Slide Serotonin 5-HT 2 receptor ligands have attracted the attention of medicinal chemists for the last half-century, first as hallucinogens and later for their antipsychotic, appetite suppressant, antiaddictive and antidepressant potential. Unlike the very potent N -benzylphenethylamine derivatives that include the abundantly studied NBOMe drugs, N...
N-Benzyl-derived phenethylamines are highly active (psychedelic) 5-HT2AR (serotonin 2A receptor) agonists used as biochemical tools and on the drug market. The impact of adding an N-benzyl substituent to the tryptamine core structure has scarcely been studied. A recent systematic exploration of N-benzyl-substituted (5-MeO-)tryptamines revealed a surprisingly low activity in a Ca2+ mobilization...
In humans, empathy is expressed through various prosocial behaviours between individuals that may be enhanced after intake of the synthetic entactogen MDMA (3,4-methylenedioxymethamphetamine, "Ecstasy") as the behavioural expression of the so-called entactogenic syndrome. Rodents may also exhibit empathy-like behaviours, such as social interaction and helping behaviour. In this regard, while...
The introduction of arylmethyl substituents on the amine nitrogen atom of phenethylamines and tryptamines often results in profound increases in their affinity and functional activity at 5-HT2 serotonin receptors. To probe the sensitivity of this effect to substantially larger N-substituents, ten derivatives of the well-characterized psychedelic phenethylamine 2C-B were prepared by appending...
