Nelivaptan
Based on 1 publication(s) in Google Scholar
Nelivaptan (SSR-149415) is a selective and orally active vasopressin V1b receptor antagonist (Ki: 3.7 and 1.3 nM for native and recombinant rat V1b receptors, respectively). Nelivaptan inhibits arginine vasopressin (AVP)-induced Ca2+ increase and corticotropin secretion. Nelivaptan can be used for research of stress, anxiety and depression.

Biological Activity
Nelivaptan (0.1-100 nM, 20 min) potently inhibits arginine vasopressin (AVP)-induced Ca2 increase in CHO cells transfected with the human V1b receptor[1].
Nelivaptan (0.9-15 nM, 45 min) inhibits [3H]AVP binding in a competitive manner in CHO cells transfected with the human V1b receptor[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Nelivaptan (1-10 mg/kg; p.o.; 1, 2, 3, 4, and 6 h before the AVP challenge) produces powerful dose-dependent inhibition of the corticotropin increase in response to exogenous AVP plus corticotropin-releasing factor (CRF) in Sprague-Dawley rats[1].
Nelivaptan (1-10 mg/kg; i.p. 30 min or 60 min before test; or p.o. for 7 days) displays anxiolytic-like activity after acute and 7-day repeated administrations in male NMRI mice [1].
Nelivaptan (30 mg/kg; i.p.; daily for two weeks) retains efficacy in reducing both measured indices of depression-like behavior (learned helplessness and anhedonia), even when neurogenesis is blocked in male Wistar rats with chronic mild stress[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Animal Model:Male Wistar rats (300-400 g, aged 3 months) with chronic mild stress[2]
-
Dosage:30 mg/kg
-
Administration:Intraperitoneal injection (i.p.); daily for two weeks
-
Result:Chronic administration reversed learned helplessness and anhedonia even when methylazoxymethanol (MAM) was administered.
Attenuated these depressive-like behaviors after 1 week.
Restored the density of Ki-67-positive cells to control levels.
-
Animal Model:Male Sprague-Dawley CD rats (275-300 g)[1]
-
Dosage:1, 3, 10, 30 mg/kg
-
Administration:Intraperitoneal injection (i.p.) or Oral gavage (p.o.); 30 min i.p. or 2 h p.o. before an exogenous AVP injection
-
Result:Antagonized AVP-induced corticotropin secretion in a dose-dependent manner by both intraperitoneal and oral routes.
The inhibition was significant from 10 mg/kg p.o. and 3 mg/kg i.p. upwards.
The inhibitory action lasted significantly for more than 2 h at 10 mg/kg i.p. and up to 4 h at 10 mg/kg p.o..
Had no effect on basal corticotropin plasma levels up to 30 mg/kg p.o..
-
Animal Model:Male Sprague-Dawley CD rats (275-300 g)[1]
-
Dosage:1, 3, 10 mg/kg
-
Administration:Oral gavage (p.o.); 1, 2, 3, 4, and 6 h before the AVP challenge (10 mg/kg)
-
Result:Produced powerful dose-dependent inhibition of the corticotropin increase in response to exogenous AVP plus corticoliberin; the effect was significant from the dose of 3 mg/kg p.o.. Complete blockade was achieved at 10 mg/kg.
Showed a fast onset of action, the inhibitory effect was maximal at 1 h after administration.
The inhibitory effect on corticotropin secretion lasted significantly more than 4 h, demonstrating a long-lasting oral effect in a specific V1b-related model.
-
Animal Model:Male NMRI mice (20 g)[1]
-
Dosage:1, 3, 10 mg/kg
-
Administration:Intraperitoneal injection (i.p.) or Oral gavage (p.o.); i.p. (1, 3, 10 mg/kg) 30 min or 60 min befeore; p.o. (10 mg/kg) for 7 days,
-
Result:In the acute experiments, i.p. and p.o. compound increased the number of punished crossings showing marked anxiolytic effects.
Post hoc analysis revealed that these effects reached statistical significance from 3 mg/kg p.o. and i.p.
The anxiolytic-like activity was still significantly maintained when given repeatedly at 10 mg/kg p.o. for 7 days.
The oral time course of the anxiolytic-like action performed at 10 mg/kg indicated that effects lasted for more than 4 h.
