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

  摘要：

  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 compound 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, (E)-N-[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.

  8-Azacoumarins的战略方针

  摘要：

  8-Azacoumarins已成为一类有前途的化合物，但由于具有挑战性而难以开发。提供了用于此类化合物的新颖，通用且实用的方法。关键的内酯化步骤使用与反式丙烯酸相连的吡啶N-氧化物作为起始原料，乙酸酐既作为活化剂，又作为溶剂。该反应涉及多个转化，包括缀合物添加，亲核芳族取代和消除。这些研究为获得8-氮杂香豆素提供了基础，使将来的工作包括发现和开发新型香豆素类药物，荧光探针，光不稳定的保护基团和其他活性分子。
