    製品説明

    Reparixin L-lysine salt is an allosteric inhibitor of chemokine receptor 1/2 (CXCR1/2) activation.

    IC50 & Target[1][5]

    CXCR1wt

    5.6 nM (IC50, in L1.2 cells)

    CXCR1Ile43Val

    80 nM (IC50, in L1.2 cells)

    CXCR1

    1 nM (IC50, in cells)

    CXCR2

    ∼100 nM (IC50, in cells)

    体外実験

    Reparixin is a potent functional inhibitor of CXCL8-induced biological activities on human PMNs with a marked selectivity (around 400-fold) for CXCR1, as shown in specific experiments on CXCR1/L1.2 and CXCR2/L1.2 transfected cells and on human PMNs. The efficacy of Reparixin is significantly lower in L1.2 cells expressing Ile43Val CXCR1 mutant (IC50 values of 5.6 nM and 80 nM for CXCR1 wt and CXCR1 Ile43Val, respectively)[1]. Reparixin is a non-competitive allosteric inhibitor of IL-8 receptors with a 400-fold higher efficacy in inhibiting CXCR1 activity than CXCR2[2].

    体内実験

    The pharmacokinetics and metabolism of Reparixin are investigated in rats and dogs after intravenous administration of [14C]-Reparixin L-lysine salt. Plasma protein binding of Reparixin is >99% in the laboratory animals and humans up to 50 μg/mL, but lower at higher concentrations. Although radioactivity is rapidly distributed into rat tissues, Vss is low (about 0.15 L/kg) in both rat and dog. Nevertheless, Reparixin is more rapidly eliminated in rats (t1/2~0.5 h) than in dogs (t1/2~10 h)[3].

    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 (5.82 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 (5.82 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.

    [1]

    L1.2 Cell suspension (1.5-3×106 cells/mL) is incubated at 37°C for 15 min in the presence of vehicle or of Reparixin (1 nM-1 μM) and next seeded in triplicates in the upper compartment of the chemotactic chamber. Different agonists are seeded in the lower compartment of the chamber at the following concentrations: 1 nM CXCL8, 0.03 nM fMLP, 10 nM CXCL1, 2.5 nM CCL2, 30 nM C5a. The chemotactic chamber is incubated at 37°C in air with 5% CO2 for 45 min (human PMNs) or 2 h (monocytes). At the end of incubation, the filter is removed, fixed, and stained and five oil immersion fields at high magnification (100×) are counted for each migration well after sample coding. L1.2 migration is evaluated using 5 μm pore size Transwell filters[1].

    Rats and Dogs[3]
    Male and female Sprague-Dawley CD (albino) rats and male Lister Hooded (partially pigmented) rats are used. Male and female beagle Dogs (age about 15 months, bodyweight range 8.3-9.4 kg at the time of dosing) are used. Rats and Dogs are dosed i.v. with repurified [14C]-Reparixin free acid and an equivalent quantity of L-lysine suitably radiodiluted with Reparixin L-lysine salt in a solution of sterile isotonic (0.9%, w/v) saline. Rats are dosed with a solution of total drug concentration 9 mg/mL at a dose volume of 5 mL/kg (30 mg free Reparixin /kg) by bolus injection into a caudal vein. Dogs are dosed with a solution of total drug concentration 100 mg/mL at a dose volume of 0.5 mL/kg (33 mg free Reparixin/kg) by bolus injection into a superficial forelimb vein.

    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.
