Procaine is a DNA-demethylating agent. Procaine acts through multiple targets and has a slow onset and a short duration of action^[1][2].

Procaine (0.01-100 microM) inhibited the 5-HT3 receptor-mediated inward current in the whole-cell patch clamp recording. Procaine appears to produce a competitive inhibition on 5-HT3 receptors with a KD of 1.7 microM^[1]. Procaine is a DNA-demethylating agent that produces a 40% reduction in 5-methylcytosine DNA content as determined by high-performance capillary electrophoresis or total DNA enzyme digestion. Procaine can also demethylate densely hypermethylated CpG islands. Procaine also has growth-inhibitory effects in these cancer cells, causing mitotic arrest^[2]. Procaine functions as an excitant of limbic system cells, and that procaine alters synaptic transmission in some, but not all, output pathways from the amygdale^[3].
