investigation of this new class of (aryloxy)acetic acid diuretics. Systematic alteration of the oxyacetic side chain has shown that the carboxylic acid function is the active species in vivo and that the ethyl ester group serves as a prodrug to enhance oral absorption. Side-chain functional groups that are incapable of generating the carboxylic acid in vivo failed to impart diuretic activity to the
从[2,3-二氯-4-(4-羟基苯甲酰基)苯氧基]乙酸乙酯的一系列氨基甲基衍生物中发现高天花板利尿钠活性,促使我们继续研究这种新的(芳氧基)乙酸利尿剂。氧乙酸侧链的系统性变化表明,羧酸功能是体内的活性物质,而乙酯基团则充当前药以增强口服吸收。不能在体内产生羧酸的侧链官能团不能赋予目标化合物利尿活性。还描述了另外的侧链修饰,包括同源性,甲基取代和杂原子取代。氧乙酸侧链环化成二氢苯并呋喃-2-羧酸生成的化合物32
