Pyridine compounds, process for the preparation thereof and pharmaceutical composition containing the same

The present invention relates to novel pyridine compounds having antiallergic activity mainly through 5-lipoxygenase inhibitory activity, antihistamine activity and/or inhibiting activity against chemical mediator release

Acrylamide derivatives as antiallergic agents. 2. Synthesis and structure-activity relationships of N-[4-[4-(diphenylmethyl)-1-piperazinyl]butyl]-3-(3-pyridyl)acrylamides

A new series of 3-(3-pyridyl)acrylamides 16, 17, 19, and 26, and 5-(3-pyridyl)-2,4-pentadienamides 20-25 were prepared and evaluated for their antiallergic activity. Several of these compounds exhibited more potent inhibitory activities than the parent compounds 1a [(E)-N-[4 [4-(diphenylmethyl)-1-piperazinyl]butyl]-3-(3-pyridyl)acrylamide] against the rat passive cutaneous anaphylaxis (PCA) reaction and the enzyme 5-lipoxygenase. Particularly, 4-[4-(diphenylmethyl)-1-piperazinyl]butyl]-3-(6-methyl-3-pyridyl)acrylamide (17p) showed an ED50 value of 3.3 mg/kg po in the rat PCA test, which was one-fifth of ketotifen and oxatomide. As compared with ketotifen and oxatomide, compound 17p (AL-3264) possessed a better balance of antiallergic properties due to inhibition of chemical mediator release, inhibition of 5-lipoxygenase, and antagonism of histamine.
