Description: RG108 is a non-nucleoside DNA methyltransferase inhibitor (DNMT inhibitor). RG108 led to a significant dose and time dependent growth inhibition and apoptosis induction in LNCaP, 22Rv1 and DU145. LNCaP and 22Rv1 also displayed decreased DNMT activity, DNMT1 expression and global DNA methylation. Interestingly, chronic treatment with RG108 significantly decreased GSTP1, APC and RAR-β2 promoter hypermethylation levels, although mRNA reexpression was only attained for GSTP1 and APC. RG108 is an effective tumor growth suppressor in most PCa cell lines tested.
