[125I]-TARC-CCR4 7.96 (pIC50) |
The GSK2239633A is an allosteric antagonist of human CCR4. GSK2239633A inhibits the binding of [125I]-TARC to human CCR4 with a pIC50 of 7.96±0.11 and also inhibits thymus- and activation-regulated chemokine-induced (TARC)-induced increases in the F-actin content of isolated human CD4+ CCR4+ T-cells with a pA2 of 7.11±0.29[1]. The effect of GSK2239633A (Compound 3) on CCL17-induced increases in the F-actin content of human CD4+ CCR4+ T cells is measured. The pEC50 value is 8.79±0.22[2].

Solvente y solubilidad
DMSO : ≥ 250 mg/mL (455.32 mM; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
* "≥" means soluble, but saturation unknown.
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.08 mg/mL (3.79 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.

Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
Protocolo
Blood is taken from normal volunteers who have taken no medication within the previous 10 days and chemokine-induced increases in the filamentous (F)-actin content of CD4+ CCR4+ T cells are measured. Briefly, the peripheral blood mononuclear cells (PBMC) are isolated and stained with fluorescein isothiocyanate-conjugated anti-human CD4 and phycoerythrin-conjugated anti-CCR4 antibodies. The cells are then incubated with GSK2239633A (1 μM) or vehicle (0.1% DMSO) for 30 min at 37°C before stimulation with agonist for 15 sec. The assay is terminated by addition of 3% formaldehyde. The fixed cells are stained with Alexa fluor-647 phalloidin and the mean fluorescence intensity of 1000 CD4+ CCR4+ cells per sample is determined. This is expressed as a fraction of the mean intensity of the CD4+ CCR4- cells in the same sample[2].

Rats and Dogs[3]
Pharmacokinetics are determined in male Wistar Han rats (277-305 g) or male Sprague Dawley (crl:CD(SD)) rats 277-305 g) and male Beagle dogs (14-16 kg; aged approximately 3-4 years) following single oral and intravenous administration to aid prediction of the likely human pharmacokinetics using precedented physiological scaling techniques. In the rat, compounds (e.g., GSK2239633A) are dosed intravenously and orally to 2 rats per compound per route. Nominal doses of 1 mg/kg are used for intravenous (iv) and oral (po) administration and studies are conducted following routine animal husbandry methods. Rats are housed in standard holding cages and maintained in a controlled environment with free access to food and water. Serial blood samples are collected via a temporary cannula inserted into the tail vein of all animals. For the intravenously dosed animals the cannula is inserted into a vein discrete from that used for dosing. The dogs are kept in slings for no longer than 2 h following the end of dosing on each phase of the study. Compounds (e.g., GSK2239633A) are dosed intravenously (bolus, 0.5 mg/kg) using an angiocath and orally (gavage; 1 mg/kg) to two male Beagle dogs per compound in a cross over design. Serial blood samples are collected from the cephalic vein via an angiocath for the first 2 h post dose and via direct venipuncture for the remainder of the study.
