CCG 203769 also displays dramatic selectivity (8- to >5000-fold) for RGS4 over other RGS proteins. CCG 203769 inhibits RGS19 with an IC50 of 140 nM (8-fold selective for RGS4) and 6 μM for RGS16 (350-fold selective for RGS4). The closely related RGS8 is very weakly inhibited (IC50>60 μM) providing >4500-fold selectivity for RGS4. CCG 203769 inhibits GSK-3β with an IC50 value of 5 μM. CCG 203769 does not inhibit the cysteine protease papain at 100 μM. CCG 203769 does not inhibit RGS7, which lacks cysteines in the RGS domain. CCG 203769 inhibits RGS/Gαo binding in an RGS-selective manner. CCG 203769 enhances Gαq-dependent cellular Ca2+ signaling in an RGS4-dependent manner. CCG 203769 also blocks the GTPase accelerating protein (GAP) activity of RGS4. In single-turnover and steady-state GTPase experiments with Gαo and Gαi1, the rate of GTP hydrolysis is strongly stimulated by RGS4, and this effect is inhibited by CCG 203769 with an IC50<1 μM[1].

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 (10.28 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.08 mg/mL (10.28 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 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.

Protocol
Steady-state hydrolysis of unlabeled GTP is measured using malachite green in a receptor-independent assay utilizing a mutant Gαi1 (R178M, A326S). These mutations facilitate the release of GDP from the enzyme making the GTP hydrolysis step rate-limiting. GTP hydrolysis is measured by mixing 6 μM mutant Gαi with 300 μM GTP in 100 μL in 96-well plates in the presence or absence of 200 nM RGS4 and CCG-203769 or DMSO (vehicle control). All assay components are diluted in a buffer comprising 50 mM HEPES at pH 7.4, 100 mM NaCl, 0.01% Lubrol, 5 mM MgCl, and 10 μg/mL BSA. The reaction is allowed to proceed for 2 h at room temperature and then is quenched with 60 μL of an HCl/malachite green dye solution. Immediately after the addition of malachite green, 10 μL of 32% w/v sodium citrate is added as a colorimetric stabilizer, followed by incubation at room temperature for 20 min. Released inorganic phosphate is measured as an increase in absorbance (A630) from the complex of phosphate with malachite green. Background control samples lacking Gα are used to determine the rate of nonenzymatic GTP hydrolysis which is subtracted[1].

Mice[1]
Young male (20-25 g; 8-9 weeks) C57BL/6J mice are used. Akinesia and bradykinesia are assessed 30 min after Raclopride, mice receive either DMSO or CCG-203769 (0.1-10 mg/kg, i.p.). Behavior is assessed 20 or 90 min after DMSO or CCG-203769.
Rats[1]
Adult Sprauge-Dawley rats receive CCG-203769 (10 mg/kg, i.v.) or saline (by i.v. infusion through the indwelling venous catheter over 30 s) while freely moving in their homecage. One minute later, saline or 0.1 mg/kg
Carbamoylcholine chloride (i.p.) is administered. Before and after i.v. infusions, catheters are flushed with approximately 0.5 mL of heparinized saline (50 U/mL) to check catheter patency and flush treatments from the dead space in the catheter.
