title: [Substituted 1,5,6,7-tetrahydro-4H-benzimidazol-4-ones as inhibitors of urease].
abstract: A comparative kinetic study of the inhibition of urea hydrolysis by 9 substituted 1,5,6,7-tetrahydro-4H-benzimidazol-4-ones (BI I-IX) has been carried out. The inhibition had reversibl competitive character; the inhibition constants K(i), varied from 29 up to 754 microM in dependence of the structure of BI I-IX. Three BI I-III, having the K(i) values from 29 to 82 microM, may be used as the potential therapeutic agents for gastroenterology for treatment of stomach and duodenal ulcers.
