製品説明

RG108 (N-Phthalyl-L-tryptophan) is an inhibitor of DNA methyltransferase with IC50 of 115 nM in a cell-free assay, does not cause trapping of covalent enzymes.

Targets

DNA methyltransferase ^[1]
(Cell-free assay)

115 nM

In Vitro
In vitro	RG108 effectively blocks DNA methyltransferases in vitro and does not cause covalent enzyme trapping in human cell lines. Incubation of cells with low micromolar concentrations of RG108 results in significant demethylation of genomic DNA without any detectable toxicity. Intriguingly, RG108 causes demethylation and reactivation of tumor suppressor genes, but it does not affect the methylation of centromeric satellite sequences. ^[1] In another study, the synthesis and in vitro analysis of a biotinylated RG108 conjugate is investigated to evaluate the interactions with DNA methyltransferase enzymes. ^[2] In a recent study, it is shown RG108 can significantly reduce the DNA methyltransferases activity in SM derived iPS cells as compared to the native SMs. ^[3]
Kinase Assay	In vitro methylation assay
Kinase 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.
