Definitions

  • the present invention relates to biphenyl butyric acid derivatives, more specifically, to novel biphenyl butyric acid derivatives represented as the following general formula (I) , useful as matrix metalloproteinase inhibitor and pharmaceutically acceptable salts thereof and a process for preparing the compounds.
  • Matrix metalloproteinase is a Ca 2+ -dependent proteinase containing zinc ion(Zn 2+ ) at its active site.
  • matrix metalloproteinases including stromelycin, collagenase and a family of gelatinase have been identified in the art.
  • MMP degrades various extracellular matrix components of collagen, laminin, proteoglycan, fibronectin, elastin and gelatin under biological conditions, which, in turn, leads to growth of articulation tissue, bone tissue and connective tissue, and remodeling of the tissues.
  • MMP is secreted as an inactive form of proenzyme, which is subsequently activated in extracellular side, together with a naturally occuring inhibitor, TIMP (tissue inhibitor of metalloproteinase) .
  • TIMP tissue inhibitor of metalloproteinase
  • MMP inhibitor is useful to prevention and treatment of all sorts of diseases caused by overexpression or overactivation of MMP.
  • diseases are, for example, rheumatoid, arthrosteitis, unusual bone resorption, osteoporosis, periodontitis, interstitial nephritis, arteriosclerosis, pulmonary emphysema, cirrhosis, cornea injury, metastasis, invasion or growth of tumor cell, autoimmune disease, disease caused by vascular emigration or infiltration of leukocytes, arterialization (s_e_e_: Beeley et al., Curr. Opin. Ther. Patents, 4(1):7-16, 1994).
  • MMP inhibitor has an anti-cancer activity in vivo along with inhibition of basement membrane remodeling in the mouse model bearing ovarian cancer (see: Cancer Res., 53:2087, 1993).
  • MMP-2 and MMP-9 among the above MMP enzymes play an essential role in angiogenesis required for the growth of cancer cells (see: Biochim. Biophys .
  • MMP-1 and MMP- 3 among MMP enzymes play an important role in the progress of arthritis as observed in much higher concentration than normal in the synovium and cartilage of a patient of rheumatoid arthritis ( ⁇ e_£: Arthritis Rheum., 35:35-42, 1992), the selectivity to MMP-l/MMP-2 is considered to play a crucial role in reducing side effects such as arthralgia. Therefore, researches have been made while focusing on the development of selective inhibitors, and many MMP inhibitors have been designed and synthesized in many aspects ( ⁇ e ⁇ : J.
  • MMP are known. In general, they have a zinc binding group (“ZBG") , which is coordinated to the zinc ion of MMP enzymes at the active site of them.

Med. Chem., 40:2525-2532, 1997).
  • new sulfonamide derivatives have been designed and synthesized, by changing PI' of the above sulfonamide inhibitor which binds to SI' sub-site of the enzymes. While the above sulfonamide inhibitors have relatively high inhibitory activity against MMP, they do not have a higher selectivity to MMP-l/MMP-2 as compared with previous peptide-mimic inhibitors. Some of them have also side effect of arthralgia in clinical trials (s_e_e_: Current Pharmaceutical Design, 5:787-819, 1999; Current Opinion in Drug Discovery & Development, 3:353-361, 2000; Exp.

  • the present inventors have made an effort to develop novel compounds whose inhibitory action on MMP and selectivity to MMP-l/MMP-2 are increased to reduce side effects, and finally found that novel synthetic inhibitors of biphenyl butyric acid derivatives selectively inhibit MMP activity in vitro.
  • a primary object of the present invention is, therefore, to provide biphenyl butyric acid derivatives inhibiting MMP activity.

  • the present test was accomplished by measuring the fluorescence intensity of a fluorescent material (7- methoxycoumarin-4-acetyl-Pro-Leu-Gly) produced from the cleavage of a fluorescent synthetic peptide substrate ( (7- methoxycoumarin-4-acetyl-Pro-Leu-Gly-Leu- ⁇ -(2,4- dinitrophenylamino) Ala-Ala-Arg-NH 2 (Sigma Chem. Co., U.S.A.)) by gelatinase A(Boehringer Manneheim cat# 1782916, from human fibrosarcoma cells) .
  • Enzymatic reaction employing a fluorescent synthetic substrate was accomplished by leaving test compounds, TNBC buffer solution (25mM Tris-HCl, pH 7.5, 0.1M NaCl, 0.01% Brij-35, 5mM CaCl 2 ) , gelatinase A (final concentration in well: 4.17nM) activated with 1 mM of APMA(aminophenylmercuric acetate) for 30 minutes at 37 °C just before the enzymatic reaction, and the substrate, fluorescent synthetic peptide (final concentration in well: 9.15uM) in 96 well plate and then reacting for 30 minutes at 37 °C, and the fluorescence intensity was measured at excitation 328nm and emission 393nm by spectrofluorimeter (Fma (molecular device)).
  • the inhibition rate(%) was calculated from the following equation:
  • A represents fluorescence intensity before the reaction with an inhibitor
  • B represents fluorescence intensity after the reaction with an inhibitor
  • C represents fluorescence intensity before the reaction without an inhibitor
  • D represents fluorescence intensity after the reaction without an inhibitor.
  • MMP-1 In vitro inhibition rate on collagenase (MMP-1) was measured in a similar manner as in Example 54, except for employing collagenase (AngioLab. Co. Ltd) with a final concentration in well of 7.25nM.
  • the present invention provides novel biphenylbutyric acid derivatives which inhibit MMP activity, their isomers and the pharmaceutically acceptable salts thereof, and a process for preparing the compounds. Since the biphenylbutyric acid derivatives of the present invention selectively inhibit MMP activity in vitro, the MMP inhibitors comprising the biphenylbutyric acid derivatives as an active ingredient can be practically applied for the prevention and treatment of diseases caused by overexpression and overactivation of MMP. .

Abstract

Cette invention, qui a trait à de nouveaux dérivés d'acide diphénylbutirique, à leurs isomères ainsi qu'à leurs sels admissibles du point de vue pharmaceutique, lesquels dérivés se révèlent des plus utiles en tant qu'inhibiteurs de la métalloprotéinase matricielle (MMP), concerne également un procédé de production de ces composés. Dans la mesure où ces dérivés d'acide diphénylbutirique inhibent, de manière sélective, l'activité des MMP in vitro, ils sont administrés dans le cadre du traitement et de la prévention de différents états pathologiques dus à une surexpression et à une suractivation de MMP.
