ABSTRACT:

SUMMARY
This invention is related to sulfonylamino acid derivatives and matrix metalloproteinase inhibitors containing sulfonylamino acid derivatives as active ingredient. More particularly, this invention is related to:
(i) matrix metalloproteinase inhibitors containing sulfonylamino acid derivatives of the formula (Ia):
wherein all the symbols are the same meaning as hereinafter defined. and non-toxic salts thereof as active ingredient,
(ii) novel sulfonylamino acid derivatives of the formula (Ib):
wherein all the symbols are the same meaning as hereinafter defined, and non-toxic salts thereof, and
(iii) process for the preparation of the compounds of the formula (Ib).
BACKGROUND
The matrix metalloproteinases (MMPs) are neutral metalloproteinases and zinc (Zn
2+
) is essential in the active site for their activation. They degrade collagen, laminin, proteoglycans, fibronectin, elastin, gelatin etc. under physiological conditions and therefore, are effective on growth and tissue remodeling of articulation tissue, bone tissue, connective tissue. At least 10 classes of MMPs which differ in primary structure are identified. As common characters of each enzymes, MMPs
(1) have Zn
2+
in the active site and the activity depends on calcium (Ca
2
+),
(2) are secreted as an inactive proenzyme and activated outside of cells,
(3) have high homology on amino acid sequence,
(4) have degradable ability on various extracellular matrix components in vivo,
(5) are regulated by tissue inhibitors of metalloproteinases (TIMP) which are specific to MMPs.
MMP inhibitors are useful for prevention and/or treatment of various diseases induced by overexpression and excess activation of MMP. Such diseases are, for example, rheumatoid, arthrosteitis, unusual bone resorption, osteoporosis, periodontitis, interstitial nephritis, arteriosclerosis, pulmonary emphysema, cirrhosis, cornea injury, metastasis of, invasion of or growth of tumor cells, autoimmune diseases (Crohn's disease, Sjogren's syndrome etc.), diseases caused by vascular emigration or infiltration of leukocytes, arterialization.
RELATED ARTS
Some compounds possessing inhibitory activity against MMP are known. A sequence in the vicinity of cleavage site of collagen (Gly-Ile-Ala-Gly or Gly-Leu-Ala-Gly) has high affinity for collagenase.
A lot of research and development of substrate analogous MMP inhibitors, which are chemically modified so as to have zinc affinity groups on a cleaving site of substrate, are carried out energetically [Inhibitors of matrix metalloproteinases (MMP's), Nigel R A Beeley, Phillip R J Ansell, Andrew J P Docherty et. al., Curr. Opin. Ther. Patents., 4, 7-16 (1994), Current Drugs Ltd ISSN 0962-2594]. However, these substrate-analogues inhibitors might have various problems. Therefor, it is desired a non-peptide inhibitor and some compounds are reported.
For example, in the specification of EP 606046, aryl-sulfonamide derivatives of the formula (X):
wherein (a) Ar
X

is hydrogen, lower alkyl, carbocyclic aryl-lower alkyl etc.; R
2X

X
and R
1X
together with the chain to which they are attached form 1, 2, 3, 4-tetrahydro-isoquinoline, piperidine etc.; Ar
X
and R
2X
are the same meaning as (a); or (c) R
1X
and R
2X
together with the carbon to which they are attached form C3-7 cycloalkane, oxa-cyclohexane, thia-cyclohexane etc. which is unsubstituted or substituted by lower alkyl; and Ar
X
and R
2X
are the same meaning as (a); are disclosed to have inhibitory activity against matrix metalloproteinase.
