Introduction : The present study is aimed at investigation of the mechanism action a new 3-substituted thietane-1,1-dioxide derivative (N-199/1) exhibiting antidepressant properties, in several tests neuropharmacological interaction. Materials and methods To N-199/1, its effect on 5-hydroxytryptophan (5-HTP)-induced head-twitch response (50 mg/kg 300 mg/kg), haloperidol-induced catalepsy (1 are...

To identify new leads for the treatment of Plasmodium falciparum malaria, we screened a panel of serotonin (5-hydroxytryptamine [5HT]) receptor agonists and antagonists and determined their effects on parasite growth. The 5HT1A receptor agonists 8-hydroxy-N-(di-n-propyl)-aminotetralin (8-OH-DPAT), 2,5-dimethoxy-4-iodoamphetamine, and 2,5-dimethoxy-4-bromophenylethylamine inhibited the growth of...

Fusion proteins were generated between the human 5-hydroxytryptamine (5-HT)1A receptor and both wild-type (Cys ) and pertussis toxin-resistant (Gly and Ile) forms of Gi1. These were expressed stably. Pertussis toxin treatment substantially reduced basal high-affinity GTPase activity in clones expressing the 5-HT1A receptor wild-type Gi1a construct but not in clones expressing 5-HT1A receptor (G...
