Navacaprant (BTRX-335140) is a selective and orally active κ opioid receptor (KOR) antagonist, has antagonist activity for κOR, μOR and δOR with IC50 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[1].
Navacaprant (BTRX-335140) (0-10 μM; 4 h) shows selective antagonist activity towards Kappa Opioid Receptor[1].
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[1].
Navacaprant (BTRX-335140) (1 mg/kg; i.p. once) blocks U-50488-induced antinociception from hot water[1].
