Biological Activity

Amodiaquine is a potent, non-competitive inhibitor of histamine N-methyl transferase with estimated Ki of 18.6 nM. It is also used as an antimalarial and anti-inflammatory agent.

in vivo

In vivo administration of a small dose amodiaquine dramatically enhanced the effect of histamine on the gastric secretion in dogs. Amodiaquine prevents severe hepatic injury and high lethality in P. acnes-primed and LPS-induced hepatitis mice. Its treatment enhances the elevation of histamine in the liver of P. acnes-primed and LPS-induced hepatitis mice without accompanying tele-methyl histamine elevation.
