General description

RG108, a non-nucleoside analog is also called [2-(1,3-dioxoisoindolin-2-yl)-3-(1H-indol-3-yl) propanoic acid.

Application

RG108 has been used:
  • in reprogramming and increasing cell plasticity of primary multipotent mesenchymal stromal cells (MMSC)
  • as an inhibitor of DNA methyltransferase (DNMTi) in human retinal pigment epithelial ARPE-19 cells
  • as a DNA methyltransferase inhibitor in C33A2 cells to test its effect on papillomavirus late gene expression (HPV16)

Biochem/physiol Actions

RG108 is a DNA methyltransferase (DMNT) inhibitor. It reactivates tumor suppressor gene expression (p16, SFRP1, secreted frizzled related protein-1, and TIMP-3) in tumor cells by DNA demethylation. RG108 also inhibits human tumor cell line (HCT116, NALM-6) proliferation and increased doubling time in culture.
RG108 is less cytotoxic compared to azacytidine (5-Aza-dCR). It mediates radiosensitivity in esophageal cancer cells (EC). RG108 is a potent epigenetic modulator and a demethylating agent. It elicits non-cytotoxic functionality and may be useful in stem cell therapies based on human bone marrow-derived mesenchymal stem cells (hBMSCs). It interacts with DNA methyltransferase 1 at the catalytic domain region.
