Tagorizine (also known as AL-3264) is a pyridylacrylamidoalkylpiperazine derivative patented by Dainippon Pharmaceutical Co., Ltd as an antiallergic agent. Tagorizine acts as 5-lipoxygenase inhibitor and blocks histamine H1-receptors in isolated guinea pig trachea, inhibits antigen-induced histamine release from isolated rat peritoneal mast cells, and suppress leukotriene production from activated human leukocytes. In preclinical models Tagorizine inhibited the antigen-induced leukotriene production in the abdominal cavity of passively sensitized rats and suppressed the arachidonic acid-induced ear edema in mice.
