    Description

    SQ22536 is an effective adenylate cyclase (AC) inhibitor.

    IC50 & Target

    adenylate cyclase (AC)[1]

    In Vitro

    SQ22536 (SQ22,536) effectively inhibits the effect of forskolin with respective IC50 values of 5 μM.
    Preincubation with graded concentrations of SQ22536 reveals that both SQ22536 effectively inhibits PACAP-induced reporter gene activation with approximate IC50 value of 5 μM.
    SQ22536 more potently inhibits forskolin-induced Elk activation (IC50=10 μM) than 8-Br-cAMP-induced Elk activation (IC50=170 μM).
    Most notably, there are substantial differences in the reported potencies of SQ22536 to inhibit the activities of recombinant AC5 and AC6, with respective IC50 values of 2 μM and 360 μM. At a greater concentration (500 μM), SQ22536 significantly inhibits neurite elongation due to either forskolin or 8-Br-cAMP[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 (12.18 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 (12.18 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.

    Cell Assay
    [1]

    HEK293 CRE-luc2P GloResponse luciferase reporter cells are transduced with retroviral vectors expressing rat PAC1hop receptors. Individual cell lines are obtained by limiting dilution cloning, and a clonal PAC1-expressing line is propagated and used for CRE luciferase assays. In brief, HEK293 CRE-luc2P cells are plated in 96-well plates (10,000 cells in 80 μL media per well) in assay media (DMEM supplemented with 1% fetal bovine serum). One day after plating, cells are treated with AC inhibitors (10 μL in assay media/well) for 30 minutes, followed by agonists (10 μL in assay media/well), and are incubated for 4 hours. Luciferase activity is determined after the addition of 100 μL/well Bright-Glo Luciferase Assay Reagent. Luminescence (RLU) is measured in a Victor3 microtiter plate reader after 2 minutes of agitation at room temperature. Cyclic AMP is measured in NS-1 cells. In brief, NS-1 cells are seeded and grown overnight in 96-well plates. The next day, cells are pretreated for 20 minutes in media containing the phosphodiesterase inhibitor 3-isobutyl-1-methylxanthine (0.5 mM) with or without SQ22536. After pretreatment with inhibitors, cells are stimulated with agonists, added as 10× solutions, for an additional 20 minutes. Intracellular cAMP is then assayed using the cAMP Biotrak enzyme immunoassay kit for measurement of nonacetylated cAMP[1].

    • 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.
