The synthesis of various derivatives of 4 chlorosalicylic acid substituted in position 5 is described. The evaluation of their diuretic potency on the rat showed 4 chloro 5 sulfamoyl 2',6' salicyloxylidide (BE 1293, xipamide, 'Aquaphor') as the most effective. The normal urinary volume is increased 10 fold by an oral dose of 100 mg/kg body weight. All changes in the molecular structure of xipamide, even acetylation, the introduction of a second sulfamoyl group or the exchange of the sulfonic group for the carbonyl group lead to a decrease in activity.
