Disease relevance of Immepip

 

Psychiatry related information on Immepip

  • The results showed that the same i.p. doses of 5 and 10 mg kg(-1) of immepip was devoid of any significant impact on the sleep/wake phases (active awake, drowsiness and slow wave sleep), except for a slight, albeit significant, decrease in sleep onset latency [3].
 

High impact information on Immepip

 

Biological context of Immepip

  • The accumulation of [3H]cAMP induced by 1 microM SKF-81297 was inhibited in a concentration-dependent manner by the selective H3 receptor agonist immepip (maximal inhibition 60+/-5%, IC50 13 +/- 5 nM) [7].
  • Neither the density of [3H]SCH-23390 binding sites (D1 receptors) nor the inhibition by SKF-81297 were affected by 1 microM immepip, ruling out a direct interaction between D1 and H3 receptors [7].
 

Anatomical context of Immepip

 

Associations of Immepip with other chemical compounds

  • In perfused ileal segments, specific agonists acting at histamine H3 receptors, ((R)-alpha-methylhistamine and immepip, 1 nmol-10 micromol/l), did not cause any change in the threshold pressure for triggering the peristaltic wave, or in the rise of the perfusion pressure during the emptying phase [11].
  • Hydroxyzine prevents isolation-induced vocalization in guinea pig pups: comparison with chlorpheniramine and immepip [12].
 

Analytical, diagnostic and therapeutic context of Immepip

  • Using the microdialysis technique in freely moving rats, we found that the histaminergic H3 agonists R-alpha-methylhistamine (RAMH) and immepip, directly administered into the BLA, augmented spontaneous release of ACh in a similar manner [13].
  • This study reports the effect of a potent and selective H3 agonist, immepip, on EEG assessed sleep/wake phases in Sprague-Dawley rats at doses that significantly modulate brain histamine release [3].
