ABSTRACT:
A series of novel 1-piperidinesulfonylurea compounds derived from a pyrimidine monocarboxylic acid have been prepared by reacting an appropriate sulfamide with an organic isocyanate or a trisubstituted urea equivalent thereof. The sulfamylureas so obtained are useful in therapy as oral hypoglycemic agents. Typical members include those compounds derived from 1,3-dimethyl-1,2,3,4-tetrahydropyrimidine-2,4-dione-5-carboxylic acid, of which 1-(bicyclo[2.2.1]hept-5-en-2-yl-endo-methyl)-3-{4-[2-(1,3-dimethyl-1,2,3,4 -tetrahydropyrimidine-2,4-dione-5-carboxamido)ethyl]-1-piperidinesulfonyl} urea is a most preferred embodiment.
