R59022 (R-59022; DKGI-I) is a novel and potent DGKalpha inhibitor and serotonin receptor antagonist. It inhibits diacylglycerol kinase with IC50 of 2.8 μM.
ln Vitro |
59-022 (1 minute, 10 μM) strengthens the aggregation [2]. R 59-022 (30 uM, 0–60 minutes) causes basophils to release more normetins [3]. In HeLa and U87 cells, R 59-022 (40 uM, 30 minutes) activates PKC [4]. In Vero cells, R 59-022 (0-10 uM, 4 hours) bursts EBOV [5].

ln Vivo |
The median survival of SCID mice transplanted with U87 GBM cells was significantly increased by R 59-022 (2 mg/kg, intraperitoneal injection, 12 days) [6].

Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (5.44 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (5.44 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More
Solubility in Formulation 3: ≥ 2.5 mg/mL (5.44 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

R59022 and ritanserin are more potent against DGKα than other DGKs when tested using various DAG species. (A) FLAG-DGKs over-expressed in HEK 293 T cells were separated on an SDS-PAGE gel and probed with FLAG antibody. A representative image is shown. Using PC:DAG:PS liposomes with dioleoyl DAG, DGK activity was tested using cell homogenate with and without (B) 20 μM R59022 and (C) 20 μM ritanserin. Liposomes were prepared with dioctanoyl DAG and DGK activity was tested with and without (D) 20 μM R59022 and (E) 20 μM ritanserin. Liposomes were prepared with stearoyl arachidonoyl DAG and DGK activity was tested with and without (F) 20 μM R59022 and (G) 20 μM ritanserin. The values shown are percent of activity from no inhibitors, which was set to 100. The activity of lysates over-expressing only GFP was less than 10% of the lysates overexpressing DGKs and did not change in the presence of inhibitors. DGK specific activity was normalized to GFP specific activity. Each bar represents mean of triplicate ± SEM of a representative experiment. One-way ANOVA was used to test statistical significance between DGK activity with inhibitor and 100% activity - DGK activity without inhibitor, followed by Tukey’s post-hoc analysis. *p<0.05.
