Certain novel benzenesulfonylurea compounds derived from a nitrogen-containing carboxylic acid have been prepared by reacting an appropriate sulfonamide with an organic isocyanate or a tri-substituted urea equivalent thereof. The sulfonylureas so obtained are useful in therapy as oral hypoglycemic agents. Typical members include those compounds derived from 2-methoxy-nicotinic acid, of which 1-cyclohexyl-3-4-[2-(5-bromo-2-methoxynicotinamido)ethyl]benzenesulfonyl} urea is a most preferred embodiment.
某些新型苯磺酰脲化合物是由含氮羧酸与合适的磺胺酰胺反应有机异氰酸酯或三取代脲等效物制备而成的。所得的磺酰脲类化合物在治疗中作为口服降糖药物具有用途。典型成员包括那些由2-甲氧基烟酸衍生的化合物,其中1-环己基-3-4-[2-(5-溴-2-甲氧基烟酰胺)乙基]苯磺酰}脲是最优选的实施形式。
