| Description | RG108 (N-Phthalyl-L-tryptophan) is a DNA methyltransferase inhibitor with an IC50 of 115 nM. |
| Targets & IC50 | DNA methyltransferase:115 nM |
| In vivo | In iPS cells derived from SM, RG108 significantly reduces DNA activity. In tumor cells, RG108 inhibits gene demethylation and reactivation without affecting the methylation of telomeric gene sequences. |
| Synonyms | N-Phthalyl-L-tryptophan |
| Kinase Assay | In vitro methylation assay: The substrate DNA for the in vitro methylation assay is a 798 bp fragment (?423/+375 relative to the initiation codon) from the promoter region of the human p16Ink4a gene. The methylation reaction contains 350 to 400 ng substrate DNA and 4 units of M.SssI methylase (0.5 μM) in a final volume of 50 μL. Inhibitors are added to final concentrations of 10, 100, 200, and 500 μM, respectively. Reactions are done at 37 °C for 2 hours. After completion, the reaction is inactivated at 65 °C for 15 minutes and the DNA is purified using PCR Purification kit. Three hundred nanograms of purified DNA is digested for 3 hours at 60 °C with 30 units of BstUI and analyzed on 2% Tris-borate EDTA agarose gels. |

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, and a total of 10 animals are to be administered, using a formulation of 
10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH2O , the resulting working solution concentration would be 2 mg/mL.Dissolve 2 mg of the compound in 100 μL DMSO to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
1) Add 100 μL of the DMSO stock solution to 400 µL PEG300 and mix thoroughly until the solution becomes clear.
2) Add 50 µL Tween 80 and mix well until fully clarified.
3) Add 450 µL Saline,PBS or ddH2O and mix thoroughly until a homogeneous solution is obtained.
