objective: argemone mexicana is a papaveracea plant; some reports have shown their antibacterial, anti-cancer, sedative and probably anti-anxiety properties. from their aerial parts, flavonoids and alkaloids have been isolated, which are intrinsically related to some actions on the central nervous system. the aim of this study was to evaluate the anxiolytic-like effects of the plant, using its ...

The effect of naloxone, a non-selective opioid antagonist on some anxiolytic and analgesic drugs is reported. Noscapine is an opioid alkaloid with antitussive effect that cannot be antagonized by naloxone. The anxiolytic-like effect of noscapine has been shown in light-dark model and elevated plus maze. In this study the effect of naloxone on anxiolytic effect of noscapine in light-dark model w...

we studied the effect of the selective alha-2 adrenoceptor blocker idazoxan and precursor serotonin (5-htp) on anxiety-related behavior in rats. the conflict drinking test, and evaluator plus-maze were used as model. idazoxan (2 mg/kg) showed an anticonflict effect, having doses dependently increased the number of punished lickes. 5-htp showed that anxiolytic-like effect in both models. this dr...

STUDY AIMS 2(S)-neopincirin (NEO) is a constituent from of Clinopodium mexicanum, which is used in traditional Mexican herbal medicine for its tranquilizing and analgesic properties. This study investigated the anxiolytic-like, sedative and antinociceptive effects of NEO in several mice models. MATERIAL AND METHODS The anxiolytic-like effect was evaluated in the hole-board (HBT) and Open Fiel...

Orphanin FQ/nociceptin (OFQ/N) is the endogenously occurring peptide ligand for the nociceptin opioid receptor (NOP) that produces anxiolytic-like effects in mice and rats. The present study assessed the anxiolytic-like activity of 8-[bis(2-methylphenyl)-methyl]-3-phenyl-8-azabicyclo[3.2.1]octan-3-ol (SCH 221510), a novel potent piperidine NOP agonist (EC(50) = 12 nM) that binds with high affin...
