体外実験

SR144528 is a potent and selective CB2 receptor antagonist with a Ki of 0.6 nM. SR144528 alone is able to stimulate in a concentration-dependent manner (EC50=26±6 nM, two experiments) the forskolin-sensitive adenylyl cyclase activity in CHO-CB2 cells with a maximum effect at 1 μM (4-fold stimulation) whereas at this concentration it has no significant effect on CHO-CB1 cells (15% inhibition)[1]. Raw 264.7 macrophages supplemented with SR144528 display reduced caspase-3 activity. SR144528 inhibits microsomal acyl-coenzymeA:cholesterol acyltransferase (ACAT) activity in a concentration-dependent manner with an IC50 value of 3.6±1.1 μM. At 10 μM, SR144528 inhibits ACAT activities ~68%[2].

体内実験

No effect on the binding of [3H]-CP 55,940 to its specific sites in the brain is observed after either oral (up to 10 mg/kg) or i.c.v. (10 μg/animal) administration of SR144528 in mice. The occupancy by SR144528 of the spleen cannabinoid receptor is time-dependent and significant for at least 18 hours after oral administration at 3 mg/kg[1]. SR144528 does not induce any significant effect on gastrointestinal (GI) motility when given alone. SR144528 does not block but enhances delayedgastric emptying[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 (5.25 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% Corn Oil

    Solubility: ≥ 2.5 mg/mL (5.25 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

MAP kinase activity is measured. Briefly, cells grown to 80% confluence are maintained in culture medium containing 0.5% foetal calf serum for 24 hour prior to the application of ligands. CHO-CB1 or -CB2 cells previously washed with PBS are incubated at 37°C in the absence (basal activity) or in the presence of SR144528 (10-9 to 3×10-6 M) for 20 min. Cells are then washed at 4°C with 0.5 mL of buffer A [50 mM Tris-HCl, pH 7.5, 150 mM NaCl, 1 mM ethyleneglycol-bis-(β-aminoethyl ether) N,N,N′,N-tetraacetic acid, 1 mM Na3PO4] and lysed for 15 min in buffer A supplemented with 1% triton X-100, 10 μg/mL aprotinin, 10 μg/mL, leupeptin, 1 mM dithiothreitol and 1 mM phenylmethylsulfonyl fluoride. The solubilized cell extracts are then clarified by centrifugation at 14,000× g for 15 min at 4°C. Aliquots (15 μL) are removed and stored at -80°C until use. Phosphorylation assays are carried out at 30°C for 30 min (linear assay conditions) with γ-[33P]ATP by using the p42/p44 MAP kinase enzyme system. The radioactivity incorporated is determined by liquid scintillation counting[1].

cAMP accumulations are carried out in CHO-CB1 or -CB2 cells. Cells are washed with phosphate-buffered saline (PBS) and incubated for 15 min at 37°C in 1 mL of PBS in the absence or in the presence of SR144528 (3×10-9 to 10-5M). Forskolin (3 μM final concentration) is added and cells are incubated for another 20 min at 37°C. The reaction is terminated by rapid aspiration of the assay medium and addition of 1.5 mL of ice-cold 50 mM Tris-HCl, pH 8, 4 mM ethylenediaminetetraacetic acid. Dishes are placed on ice for 5 min and then the extracts are transferred to a glass tube. Extracts are boiled and centrifuged for 10 min at 3500 g to eliminate cell debris. Aliquots from supernatant are dried and the cAMP concentration is determined by radioimmunoassay by using the scintillant proximity assay system. The basal activity is determined in the absence of forskolin[1].

Male Wistar rats (240 to 300 g) are used in this study. One week after the animals arrived at the laboratory, three different sets of experiments are carried out. In the third set of experiments, SR144528 (1 mg/kg i.p.) is administered in rats. The effect of SR144528 is also analyzed in vehicle-treated rats. SR144528 volume is adjusted to a maximum of 4 to 5 mL/kg[3].

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.
