Background:

Procaine hydrochloride is a local anesthetic drug of the amino ester group.Target: OthersProcaine hydrochloride is a local anesthetic of the ester type that has a slow onset and a short duration of action.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].
