1,8-Naphthyridines VI. Synthesis and anti-inflammatory activity of 5-(alkylamino)-N,N-diethyl[1,2,4]triazolo[4,3-a][1,8]naphthyridine-6-carboxamides with a new substitution pattern on the triazole ring

in which the 9-alkyl substituent was replaced by an ester or amide group (compounds 3a-i), was prepared and tested (inhibition of carrageenan-induced paw edema in the rat). Also two 5-(N-alkyl,N-acylamino) derivatives (compounds 4a,b) were synthesized and evaluated for the same purpose. Even though the general trend for these new [1,2,4]triazolo[4,3-a][1,8]naphthyridine derivatives was a decrease
基于9-烷基-N,N-二烷基-5-(烷基氨基)[1,2,4]三唑并[4,3-a] [1,8]萘啶-显示的良好的抗炎特性。制备并测试了6碳基乙酰胺1的一系列类似物,其中9-烷基取代基被酯或酰胺基取代(化合物3a-i)(抑制角叉菜胶诱发的爪水肿)。鼠)。还合成了两种5-(N-烷基,N-酰基氨基)衍生物(化合物4a,b),并出于相同目的对其进行了评估。尽管这些新的[1,2,4]三唑并[4,3-a] [1,8]萘啶衍生物的总体趋势是与化合物1相比活性降低,但一些新合成的化合物仍显示出良好的抗-发炎的特性。
