    Description

    DSRM-3716 (5-Iodoisoquinoline) is a potent and selective SARM1 NADase inhibitor with an IC50 of 75 nM. DSRM-3716 is selective against other NAD+-processing enzymes, receptors, and transporters. DSRM-3716 provides robust axon protection[1].

    IC50 & Target

    IC50: 75 nM (SARM1 NADase)[1]
    In Vitro

    DSRM-3716 treatment produces dose-dependent inhibition of cADPR increase (IC50 of 2.8 μM) and substantial preservation of NAD+ in these cultures in a manner consistent with engagement and inhibition of SARM1 enzymatic NADase activity inside the cells[1].
    DSRM-3716 prevents neurofilament light chain (NfL) release from severed axons in a dose-dependent manner, with an IC50 of ~2 μM[1].
    The potency of DSRM-3716 to inhibit cADPR increase caused by axotomy (IC50 of 2.8 μM) is similar to the potency required to prevent axonal degeneration (IC50 of 2.1 μM)[1].
    DSRM-3716 inhibits the SARM1-dependent cell destruction pathway triggered by Rotenone in sensory neurons[1].

    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 (9.80 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 (9.80 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.

    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.
