A series of novel N-aryl-7-chloro-4-methyl-2-oxo-1,2-dihydroquinoline-6-sulfonamides were obtained. The structure-activity relationship (SAR) approach was used to study their diuretic effect on rats. Diuretic activity was exhibited by all the test compounds, with 7-chloro-4-methyl-2-oxo-1,2-dihydroquinoline-6-sulfonanilide being most active. A SAR analysis revealed that the substituted (especially ortho-substituted in the benzene ring) arylamides diminish diuresis compared to the most active compound. For the most and least active compounds, their effects on the electrolyte excretion (Na+, K+, and Cl−) and creatinine level were also studied.
获得了一系列新型N-芳基-7-氯-4-甲基-2-氧-1,2-二氢喹啉-6-磺酰胺。采用构效关系(SAR)方法研究了它们对大鼠的利尿作用。所有测试化合物均表现出利尿活性,其中7-氯-4-甲基-2-氧-1,2-二氢喹啉-6-磺酰苯胺活性最强。SAR分析显示,取代的(尤其是苯环上的邻位取代)芳基酰胺相比于活性最强的化合物,其利尿作用减弱。对于活性最强和最弱的化合物,还研究了它们对电解质排泄(Na+、K+和Cl-)和肌酐水平的影响。
