Description

D-JNKI-1 (AM-111) is a highly potent and cell-permeable peptide inhibitor of JNK.

IC50 & Target[1]

JNK

 

In Vitro

D-JNKI-1 (AM-111; 1 μM-1 mM) treatment prevents apoptosis and loss of neomycin-exposed hair cells[1].

In Vivo

D-JNKI-1 (AM-111; 10 μM) prevents nearly all hair cell death and permanent hearing loss induced by neomycin ototoxicity in the scala tympani of the guinea pig cochlea. Local delivery of D-JNKI-1 also prevents acoustic trauma-induced permanent hearing loss in a dose-dependent manner[1]. D-JNKI-1 (0.3 mg/kg, i.p.) reverses these pathological events in the brain mitochondria of the rat and almost completely abolishes cytochrome c release and PARP cleavage[2]. D-JNKI-1 (1 μg/kg, s.c.) results in a significant decrease in the disease activity index, and reduces the expression of CD4+ and CD8+ cells in mice[3].

In Vivo:

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    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (0.65 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

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

    Solubility: ≥ 2.5 mg/mL (0.65 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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:  PBS

    Solubility: 25 mg/mL (6.54 mM); Clear solution; Need ultrasonic

  • Protocol 2

    Add each solvent one by one:  Saline

    Solubility: 50 mg/mL (13.08 mM); Clear solution; Need ultrasonic

Animal Administration
[3]

D-JNKI-1 is dissolved in a 0.9% sodium chloride solution for subcutaneous application. Each group (the 1.0% DSS group and the 1.5% DSS group) is randomly subdivided into an intervention group (n = 15) and a control group (n = 15). The mice in the intervention group receive three subcutaneous nuchal administrations of 1 μg/kg D-JNKI-1 on days 2, 12, and 22. The mice in the control group receive physiological saline subcutaneously as a negative control at the same time points in a comparable stress situation.

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.
