Rational inhibition: Conjugates of procainamide were produced by rapid synthetic pathways. Several compounds resulted in extremely potent inhibitors of the murine catalytic Dnmt3A/3L complex and of human DNMT1. The inhibition potency of procainamide conjugated to phtalimide depended on the length of the linker. Such conjugates also showed strong cytotoxicity against two tumour cell lines.
