Product Description
Navacaprant (BTRX-335140) is a selective and orally active κ opioid receptor (KOR) antagonist, has antagonist activity for κOR, μOR and δOR with IC 50 values of 0.8 nM, 110 nM, and 6500 nM, respectively.Navacaprant endows with favorable in vitro ADMET and in vivo pharmacokinetic profiles and medication-like duration of action in rats. Navacaprant distributes well into the CNS and can be used for the research of neuropathy
In Vitro
Navacaprant (BTRX-335140) (0-10 μM; 4 h) shows selective antagonist activity towards Kappa Opioid Receptor. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Cell Viability AssayCell Line: OPRK1-BLA U2OS cells Concentration: 0-10 μM Incubation Time: 4 hours Result: Exibited antagonist activity to KOR, DOR and MOR with IC 50 values of 0.8, 110 and 6500 nM respectively, and showed selective antagonist activity to KOR.
In Vivo
Navacaprant (BTRX-335140) (0.01-3 mg/kg; p.o. once) reduces U69,593- stimulated plasma prolactin secretion to levels of without U69,593 treatment . Navacaprant (BTRX-335140) (1 mg/kg; i.p. once) blocks U-50488-induced antinociception from hot water . 1.19 Pharmacokinetic Parameters of BTRX-335140 in rodents .

Animal Model: Rat PRL model Dosage: 0.01, 0.03, 0.1, 0.3, 1 and 3 mg/kg Administration: Oral gavage; 0.01-3 mg/kg once Result: Effectively decreased the high level prolactin caused by U69,593 even at a dosage of 0.1 mg/kg. Animal Model: Adult male ICR mice with tail dipped into 50°C hot water Dosage: 1 mg/kg Administration: Intraperitoneal injection; 1 mg/kg once Result: Blocked the U-50488-induced antinociception at 1 h but not at 24 h pretreatment time and showed a medication-like duration of action in blocking the KOR.
This compound belongs to the class of organic compounds known as aminoquinolines and derivatives. These are organic compounds containing an amino group attached to a quinoline ring system.
