生物活性

GSK2239633A is a CC-chemokine receptor 4 (CCR4) antagonist, which inhibits the binding of [125I]-TARC to human CCR4 with a pIC50 of 7.96 ± 0.11.

IC50 & Target

[125I]-TARC-CCR4

7.96 (pIC50)

体外研究
(In Vitro)

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].

体内研究
(In Vivo)

Following intravenous dosing, plasma GSK2239633A displays rapid, bi-phasic distribution and slow terminal elimination (t1/2: 13.5 hours), suggesting that GSK2239633A is a low to moderate clearance drug. Following oral dosing, blood levels of GSK2239633A reach Cmax rapidly (median tmax: 1.0-1.5 hours). Estimated GSK2239633A bioavailability is low with a maximum value determined of only 16%[1]. GSK2239633A (Compound 9) demonstrates good pharmacokinetic data in preclinical animal studies (bioavailability in rats and beagle dogs 85% and 97% respectively)[3].

Cell Assay
[2]

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].

Animal Administration
[3]

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.
