KNT-127

KNT-127 is a selective and BBB-penetrant δ-opioid receptor (DOR) agonist (Ki = 0.16 nM) . KNT-127 is highly selective to the δ receptor, with Ki values of 0.16, 21.3 and 153 nM for δ, μ and κ receptors, respectively. KNT-127 acts as a biased ligand that mainly activates cyclic adenosine monophosphate (cAMP) signaling with lower beta-arrestin signaling activation. KNT-127 increases the release of dopamine and L-glutamate in the striatum, nucleus accumbens, and prefrontal cortex. KNT-127 exhibits antidepressant- and anxiolytic-like effects. KNT-127 can be studied in research on neurological diseases[1][2][3][4][5].
