&agr;-hydroxy, -amino, and halo derivatives of &bgr;-sulfonyl hydroxamic acids as matrix metallopropteinases inhibitors

The present invention provides a compound of formula (I) or a pharmaceutically acceptable salt thereof. Such compounds may be incorporated into pharmaceutical compositions which can inhibit various enzymes from the matrix metalloproteinase family.

&bgr;-sulfonyl hydroxamic acids

The present invention provides a compound of formula I ##STR1## or pharmaceutical acceptable salts thereof wherein R.sub.1 is C.sub.4-12 alkyl, C.sub.4-12 alkenyl, C.sub.4-12 alkynyl, --(CH.sub.2).sub.h -C.sub.3-8 cycloalkyl, --(CH.sub.2).sub.h -aryl, or --(CH.sub.2).sub.h -het; R.sub.2 is C.sub.1-12 alkyl, C.sub.2-12 alkenyl, C.sub.2-12 alkynyl, --(CH.sub.2).sub.h -C.sub.3-8 cycloalkyl, --(CH.sub.2).sub.h -C.sub.3-8 cycloalkenyl, --(CH.sub.2).sub.h -aryl, --(CH.sub.2).sub.h -het, --(CH.sub.2).sub.h -Q, --(CH.sub.2).sub.i -X-R.sub.4, or --(CH.sub.2).sub.i CHR.sub.5 R.sub.6. The compounds are inhibitors of matrix metalloproteinases involved in tissue degradation.

.beta.-sulfonyl hydroxamic acids

The present invention provides novel thiadiazole derivatives represented by formula I: ##STR1## or pharmaceutical acceptable salts thereof wherein the compounds of the present invention inhibit various enzymes from the matrix metalloproteinase family, predominantly stromelysins, and hence are useful for the treatment of matrix metallo endoproteinase diseases such as osteoarthritis, rheumatoid arthritis, septic arthritis, osteopenias such as osteoporosis, tumor metastasis (invasion and growth), periodontitis, gingivitis, corneal ulceration, dermal ulceration, gastric ulceration, and other diseases related to connective tissue degradation.
