Disease relevance of S-14671

  • In vivo, S 14671 induced the typical 5-HT1A agonist-induced responses of hypothermia and spontaneous tail-flicks at doses as low as greater than or equal to 5 micrograms/kg s.c. and greater than or equal to 40 micrograms/kg s.c., respectively [1].

High impact information on S-14671

  • S 14671 showed a very high affinity for 5-HT1A sites (pKi, 9.3) as compared to the reference ligands (pKi values, 9.2, 8.7, 8.7, 7.9 and 8.7, respectively) [2].
  • Furthermore, S 14671 acted as an antagonist of 5-HT-stimulated phosphoinositide turnover in rat choroid plexus (5-HT1C) and cortex (5-HT2) [2].
  • Although showing low affinity at 5-HT1B and 5-HT3 sites, S 14671 displayed significant affinity at both 5-HT1C and 5-HT2 sites; pKi, 7.8 in each case [2].
  • Activation of presynaptic receptors was demonstrated by inhibition of the electrical activity of the dorsal raphe nucleus with the following order of relative potency: S 14671 greater than 8-OH-DPAT greater than WY 50,324 greater than BMY 7378 greater than buspirone [2].
  • Spiperone, which acts as a pure 5-HT1A antagonist at raphe 5-HT1A receptors, blocked the action of S 14671 [2].

Anatomical context of S-14671

  • Buspirone, 8-OH-DPAT and S 14671 (1-[2-(2-thenoylamino)ethyl]- 4[1-(7-methoxynaphtyl)]-piperazine), claimed to be 5-HT1A receptor agonists, did not reduce forskolin-stimulated cAMP formation in the cerebral cortex [3].

Associations of S-14671 with other chemical compounds

  • In vivo, they both dose dependently blocked the flat-body posture and corticosterone secretion provoked by an action of the 5-HT1A receptor agonist, S 14671 (1-[2-(2-thenoyl-amino)ethyl]-4-[1-(7- methoxynaphtyl)]piperazine), at postsynaptic 5-HT1A receptors [4].
  • The anticonflict activity of S 14671 (0.01 mg/kg) was significantly antagonised by the 5-HT1A receptor antagonist, (-)-alprenolol (10 mg/kg), but not by combined treatment with the selective beta 1 receptor antagonist, betaxolol, and the selective beta 2 receptor antagonist, ICI 118,551 [5].
