New series of pyrimido[1,6-a]azepines were prepared through reaction of the key amino compound 4 with various reagents to give a variety of 3-N-substituted amino derivatives 5–13. The synthesized compounds included the Mannich bases 5a–c, the formimidic acid ester 6, the phenylformamidines 7a–c, the benzylidine amino derivatives 8a–c, the acetic acid derivatives 9, 10a–c and 11, the carbamoylformates
通过氨基化合物键的反应,制备新系列嘧啶并[1,6-α]氮杂的4与各种试剂,从而提供多种的3-N-取代的氨基衍生物5 - 13。合成的化合物包括曼尼希碱5A - Ç,所述formimidic酸酯6中,phenylformamidines 7A - Ç中,苯亚甲基氨基的衍生物8A - Ç,乙酸衍生物9,图10A - Ç和11,所述carbamoylformates 12a中,b和酰胺类13a,b。使用双氯芬酸钠作为参比药物,使用角叉菜胶诱导的大鼠足水肿筛选所有化合物的抗炎活性。此外,还计算出活性最高的化合物的溃疡指数。化合物3,4,图8a,Ç,11和12a中,b显示出活性比用没有或最小胃溃疡双氯芬酸钠类似或更高。没有溃疡作用的最具活性的化合物是氨基衍生物4(IC 50 = 6.61 mmol / kg)。
