Description: DESCRIPTION MMPINHΓBΓTOR Technical Field The present invention relates to new compounds and pharmaceutically acceptable salts thereof. More particularly, it relates to new compounds and pharmaceutically acceptable salts thereof which are useful as inhibitors of matrix metalloproteinases (hereinafter to be referred to as MMP) or the production of tumor necrosis factor (hereinafter to be referred to as TNF ), to pharmaceutical compositions comprising the same, to use of the same as medicaments, and to methods for using the same therapeutically in the treatment and/ or the prevention of MMP- or TNF -mediated diseases. Background Art Some piperazine compounds to be useful as metalloproteinase inhibitors, or the like are known (WO 97/20824, etc.). Disclosure of the Invention One object of the present invention is to provide new and useful compounds and pharmaceutically acceptable salts thereof, and to provide a process for preparing said new compound and salts thereof, which have pharmacological activities such as MMP- or TNF -inhibitory activity and the like. Another object of the present invention is to provide a pharmaceutical composition comprising, as an active ingredient, said compound or a pharmaceutically acceptable salt thereof. A further object of the present invention is to provide use of said compounds and pharmaceutically acceptable salts thereof as medicaments for prophylactic and therapeutic treatment of MMP- or TNF -mediated diseases. A still further object of the present invention is to provide a method for using the same for the treatment and/ or the prevention of MMP- or TNF -mediated diseases in mammals, especially humans. The compounds of the present invention have inhibitory activity on MMP or the production of TNF , and are useful for the treatment and/or prevention of diseases such as stroke, arthritis, cancer, tissue ulceration, decubitus ulcer, restenosis, periodontal disease, epidermolysis buUosa, scleritis, psoriasis and other diseases characterized by matrix metalloproteinase activity, as well as AIDS, sepsis, septic shock and other diseases caused by the production of TNFα . There are a number of structurally related metalloproteases which effect the breakdown of structural proteins. Matrix-degrading metallo- proteases, such as gelatinase (MMP-2, MMP-9), stromelysin (MMP-3) and collagenase (MMP-1, MMP-8, MMP-13), are involved in tissue matrix degradation and have been implicated in many pathological conditions involving abnormal connective tissue and basement membrane matrix metabolism, such as arthritis (e.g., O-feoarthritis and rheumatoid arthritis), cerebral disease (e.g., stroke, etc.), tissue ulceration (e.g. , corneal, epidermal and gastric ulcerations), abnormal wound healing, periodontal disease, bone disease (e.g., Paget's disease and osteoporosis), tumor metastasis or invasion and HrV-infection. A tumor necrosis factor is recognized to be involved in many infections and autoimmune diseases. Furthermore, it has been shown that TNF is the prime mediator of the inflammatory response seen in sepsis and septic shock.
