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.

体内実験

KNT-127 (10 mg/kg, s.c., single dose) exerts antidepressant-like effect and activates the mTOR signaling pathway in mPFC and amygdala in naïve mice with depression-like helplessness behavior[1].
KNT-127 (0.4 nmol, local infusion, single dose 15 min before test) significantly reduces immobility when infused into infralimbic prefrontal cortex (IL-PFC) but not prelimbic prefrontal cortexin cannula-implanted mice model[1].
KNT-127 (0.4 nmol, s.c., single dose 30 min before test) increases social interaction time with the target mouse and increases sucrose consumption in male and female cVSDS mice model, where both can be blocked by i.c.v. Rapamycin (HY-10219)[1].
KNT-127 (1-10 mg/kg/day, s.c., 14 d) does not influence hippocampal neurogenesis under normal states in naïve mice, unlike conventional antidepressents[2].
KNT-127 (3 mg/kg/day, s.c., 28 d) exerts antidepressant-like effects without affecting immature neurons of 10-day stress exposed cVSDS mice[2].
KNT-127 (3 mg/kg/day, s.c., 30 min before each stress session) suppresses the emergence of depressive-like symptoms and decreases newborn neuron survival rate in cVSDS mice[2].
KNT-127 (5 mg/kg/day, s.c., single dose) significantly reduces the cortical spreading depression (CSD) events and inhibits chronic migraine-associated allodynia in C57BL6/J mice[3].
KNT-127 (0.1-1 mg/kg, i.p., single dose) dose dependently increases striatal, accumbal, and pre-frontal releases of dopamine in male Sprague-Dawley rats[5].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Naïve mice with depression-like helplessness behavior[1]
Dosage: 10 mg/kg
Administration: Subcutaneous injection (s.c.), single dose
Result: Decreased the immobility count.
Did not alter the locomotor activity of mice over 40 min post-injection.
Was reversed by prior i.c.v. injection of the DOP inhibitor Naltrindole (10 nmol/5 μL).
Indicated that KNT-127 exerts an antidepressant-like action through DOP stimulation.
Animal Model: Naïve mice with depression-like helplessness behavior and mTOR inhibitor Rapamycin[1]
Dosage: 10 mg/kg
Administration: Subcutaneous injection (s.c.), single dose, 30 min after i.c.v. of Rapamycin (HY-10219) (0.2 nmol)
Result: Increased phosphorylation of Akt (a protein upstream of mTOR complex 1-mTORC1), in the mPFC but not in the amygdala.
Increased phosphorylation of ERK in the amygdala but not in the mPFC.
Increased the phosphorylation of p70S6K, a protein kinase downstream of mTORC1, in both mPFC and amygdala, and both responses were inhibited by i.c.v. Rapamycin.
Activated glutamatergic system in the IL-PFC via the mTOR signaling pathway and GABAA receptors, whilst suppresses GABAergic synapse currents in the IL-PFC.
Suppressed GABAergic synapse currents in the IL-PFC.
Animal Model: Male Sprague-Dawley rats (250-300 g)[5]
Dosage: 1 mg/kg
Administration: Intraperitoneal injection (i.p.), single dose
Result: Was inhibited by 1 nM BNTX (HY-169867) pre-perfusion on its induction of striatal and accumbal releases of dopamine.
Was inhibited by 50 μM MK801 (HY-15084B) pre-perfusion on its induction of striatal and accumbal releases of dopamine.
Enhanced pre-frontal dopamine release with the pre-perfusion of Muscimol (50 μM). Was inhibited by 25 μM Sulpiride (HY-B1019) pre-perfusion on its reduction of accumbal releases of GABA.

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 1.25 mg/mL (3.36 mM); Clear solution

    This protocol yields a clear solution of ≥ 1.25 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
