IC50 & Target

Ki: 0.48 nM (bradykinin B1 receptor, Human MRC5), 0.73 nM (bradykinin B1 receptor, Human HEK-B1), 481 nM (bradykinin B2 receptor, guinea pig ileum membranes), 358 nM (bradykinin B2 receptor, Human CHO-B2)[1]
In Vitro

SSR240612 is a potent bradykinin B1 receptor antagonist, with Kis of 0.48 nM and 0.73 nM for B2 kinin receptors of human fibroblast MRC5 and HEK cells expressing human B1 receptors, 481 nM and 358 nM for B1 receptors of guinea pig ileum membranes and CHO cells expressing human B1 receptor, respectively. SSR240612 inhibits inositol phosphate 1 formation with an IC50 of 1.9 nM, but shows no obvious effect on inositol phosphate-1 formation induced by BK (3 nM) activation of B2 receptor in human fibroblast MRC5[1].

In Vivo

SSR240612 (10 mg/kg p.o. or 0.3, 1 mg/kg i.p.) obviously blocks the des-Arg9-BK-induced paw edema in the mice. SSR240612 (10 and 30 mg/kg) reduces the duration of the late phase of paw licking in a dose dependent manner in the formalin model of inflammation in mice. SSR240612 (0.3, 3, and 30 mg/kg, p.o.) treatment before capsaicin potently and non-concentration-dependently reduces the ear edema. SSR240612 (0.3 mg/kg, i.v.) also suppresses the tissue destruction and neutrophil accumulation in the rat intestine, after splanchnic artery occlusion/reperfusion. Moreover, SSR240612 (1 and 3 mg/kg p.o.) dramacally increases the withdrawal latencies in the thermal hyperalgesia induced by UV irradiation in rats[1]. SSR240612 inhibits tactile and cold allodynia at 3 h in glucose-fed rats but had no effect in control rats with ID50s of 5.5 and 7.1 mg/kg, respectively. SSR240612 shows no effect on plasma glucose and insulin, insulin resistance (HOMA index) and aortic superoxide anion production in glucose-fed rats at 10 mg/kg[2].

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 (3.15 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 (3.15 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.

[3H]Lys0-des-Arg9-BK binding to cell membranes is performed in binding buffer of the following composition: 137 mM NaCl, 5.4 mM KCl, 1.05 mM MgCl2, 1.8 mM CaCl2, 1.2 mM NaH2PO4, 15.5 mM NaHCO3, 10 mM HEPES, 1 g/L bovine serum albumin (BSA), 140 mg/L bacitracin, and 1 μM captopril, pH 7.4. Membranes are incubated for 30 min at 25°C in 500 μL of binding buffer containing 1 nM [3H]Lys0-des-Arg9-BK for competition curves or 0.1 to 10 nM for saturation isotherms. Filters are washed three times with 5 mL of binding buffer, and radioactivity is determined by liquid scintillation spectrometry. Nonspecific binding is determined by the addition of 1 μM of unlabeled Lys0-des-Arg9BK[1].

Animal Administration
[1]

Mice[1]
Groups of eight male albino mice under isoflurane anesthesia receive a 20-μL intraplantar injection into the right hind paw of 5 μg of IL-1β in phosphate-buffered saline/0.1% BSA. Forty minutes later (T = 0), mice under anesthesia receive a 20-μL intraplantar injection in the same paw of des-Arg9-BK (10 μg/paw) in water. SSR240612 or vehicle [5% (v/v) ethanol and 5% (v/v) Tween 80 in water] is administered by oral route at the doses of 1, 3, and 10 mg/kg 1 h before des-Arg9-BK injection and by intraperitoneal route at the doses of 0.1, 0.3, and 1 mg/kg 40 min before des-Arg9-BK injection. Paw volume is measured with a plethysmometer at T = -2 h (initial measurement) and at several times after edema induction (T = 20, 40, 60, and 120 min). Paw edema volume is expressed in milliliters as the difference between the paw volume at each time after edema induction and the initial paw volume. Results for each group are expressed as mean ± S.E.M. of individual paw edema volumes. Statistical analysis is performed after verification of normality and homogeneity of variances using repeated ANOVA, then Duncan's test, treated groups versus des-Arg9-BK control group[1].
Rats[1]
SSR240612 (suspended with 0.1% Tween 80 in saline) is administered by the oral route in a volume of 20 mL/kg, 2 h before the thermal hyperalgesia measurement. In the time course study, the compound is administered at 3 mg/kg p.o. 0.08, 0.25, 0.5, 1, 2, 4, 6, 8, and 24 h before measuring the withdrawal latencies in rats. Results are expressed in seconds as mean withdrawal latencies (s) ± S.E.M., and statistical analyses are performed using a two-way ANOVA followed by Dunnett's test[1].

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.
