It was proved that current anti-allergic drugs comprise piperazine - and acrylic acid segments. These compounds were structurally designed as 5-lipoxygenase inhibitors depending on two action mechanisms of the ready drugs used to treat allergy e.g. (Oxatomide), which contains piperazine moiety, its anti-allergic effects possess antagonist activities against chemical mediators such as histamine, Serotonine and leukotriencs (which cause allergy). Also, (Tranilast), which contains acrylic acid segment; its activity depends on inhibition of mediator release. In harmony with these findings new structures having anti-allergic properties are proposed in this manuscript. New products, (5a-u) with expected better biological activities and decreased side effects were synthesized by the addition of an amino acid conjugate of cinnamic acid to a piperazine segment. Their antiallergic and anti-inflammatory activities were evaluated. Most of them show promising activities.
