ChEBI: 4-Quinolone-3-Carboxamide CB2 Ligand is a member of quinolines.
ki: 0.6 nm4-quinolone-3-carboxamide cb2 ligand is a ligand of the cb2 receptor.cannabinoids (cbs) and their synthetic analogs exhibit biochemical and pharmacological effects via interacting with the central cb1 and peripheral cb2 receptors. the cb2 receptor has emerged as a pharmacological target for treating osteoporosis, and for eliciting antinociceptive effects in various pain models .
previous study found that 4-quinolone-3-carboxamide cb2 ligand was a selective, high-affinity ligand of the cb2 receptor, displaying an in vitro ki values of 0.6 nm for cb2 and over 10,000 nm for cb1 [1].
in animal study, it was found that 4-quinolone-3-carboxamide cb2 ligand at a dose of 6 mg/kg showed antinociceptive activity in a formalin test of nocifensive response in mice. moreover, such analgesic affect could not be significantly reversed by the cb2 antagonist am630 treatment, which suggested that 4-quinolone-3-carboxamide cb2 ligand might behave as an inverse agonist [1].
