derivatives of naproxen were synthesized through the reaction of naprexenoyl chloride with amine derivatives containing pyrazole moiety. The synthesized compounds were screened for anti-inflammatory, analgesic, and ulcerogenic activities. Screening of anti-inflammatory revealed that compound 5 having a 1,3-diphenyl-pyrazol-4-yl moiety had the most promising activity. Compounds 8, 9, and 12, possessing 3
萘普生酰肼与甲酰基吡唑,乙酰丙酮,烯胺酮,曼尼希碱和芳基肼基苯甲腈衍生物反应合成了许多含有各种吡唑甲酰胺的萘普生衍生物。同样,萘普生的许多衍生物是通过萘普烯二酰氯与含有吡唑部分的胺衍生物反应而合成的。筛选合成的化合物的抗炎,止痛和促溃疡活性。抗炎剂的筛选显示具有1,3-二苯基-吡唑-4-基部分的化合物5具有最有希望的活性。化合物8,9,和12分别具有3,5-二甲基-吡唑-1-基,3-苯基-吡唑-1-基和3,5-二氨基-4-(4-甲氧基苯基偶氮)-吡唑-1-基的,显示中等活动。而且,化合物8和12显示出比参考药物更高的镇痛活性。具有致溃疡作用的是具有甲氧苯基吡唑啉部分的化合物22,没有致溃疡作用。
