Cyclic hydroxamic acids as inhibitors of matrix metalloproteinases and/or TNF- .alpha. converting enzyme (TACE)

   
   

The present application describes novel cyclic hydroxamic acids of formula I: ##STR1## or pharmaceutically acceptable salt forms thereof, wherein ring B is a 5-7 membered cyclic system containing from 0-2 heteroatoms selected from O, N, NR.sup.1, and S(O).sub.p, and 0-1 carbonyl groups and the other variables are defined in the present specification, which are useful as inhibitors of matrix metalloproteinases (MMP), TNF-.alpha. converting enzyme (TACE), aggrecanase or a combination thereof, pharmaceutical compositions containing the same, and methods of using the same.

L'application actuelle décrit les acides hydroxamiques cycliques de roman de la formule I : ## du ## STR1 ou pharmaceutiquement le sel acceptable forme en, où l'anneau B est un 5-7 membered le système cyclique contenant de 0-2 heteroatoms choisis parmi O, N, NR.sup.1, et S(O).sub.p, et 0-1 groupes carbonyliques et les autres variables sont définis dans les spécifications, qui sont utiles comme inhibiteurs des metalloproteinases de matrice (MMP), de l'enzyme convertissante de TNF-.alpha. (TACE), de l'aggrecanase ou d'une combinaison en, les compositions pharmaceutiques contenant la même chose, et des méthodes d'employer la même chose.
