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.
- ZBGs include hydroxamic acid, carboxylic acid, phosphoric acid, phosphinic acid, thiol and so forth ( ⁇ e_ ⁇ : WO 92/09564; WO
- the peptide-mimic inhibitors are known to contain a hydroxamic acid as a ZBG and display a broad spectrum for MMP enzymes.
- non-peptide inhibitors were developed to solve the said problems which are substantially distinguished in terms of chemical structure from the above peptide-mimic inhibitors having simple sulfonyl amino acid derivative represented as a chemical formula below (s_e_e_: USP 5,506,242; J. 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. Opin. Invest.
- biphenyl butyric acid derivatives as MMP inhibitors have been designed and reported (s_e_e_: USP 5,789,434; USP 5,854,277; USP 5,859,047; USP 5,861,427; USP 5,861,428; USP 5,874,473; USP 5,886,022; USP 5,886,024; USP 5,886,043) .
- 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 other object of the invention is to provide a process for preparing the said compounds.
