有用な酵素阻害剤に関する。Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a novel cyclohexanecarbonhydroxamic acid derivative, and more particularly, to a cyclohexanecarbonhydroxamic acid derivative having both protease inhibitory activity and urease inhibitory activity, or its pharmaceutical composition. The present invention relates to an enzyme inhibitor useful as an anti-ulcer agent, etc., containing the same as an active ingredient.

にプラスミンが多量に存在すると出血性疾患を生ずる。(Prior Art) Many types of enzymes exist in living bodies and are known to be associated with various diseases. For example, proteolytic enzymes such as plasmin, trypsin, and kallikrein are no exception, and are known to induce various diseases if they are abnormally activated for some reason. For example, the presence of large amounts of plasmin in the blood causes bleeding disorders.

For example, antiplasmin agents are useful as hemostatic agents, anti-ulcer agents, and anti-inflammatory agents;
Anti-trypsin agents are useful as agents for treating rhinitis, and anti-kallikrein agents are useful as anti-ulcer agents.

ない。On the other hand, along with proteolytic enzymes, urease is an enzyme known to be associated with diseases. Urease is an enzyme that decomposes urea into ammonia and carbon dioxide, and it is known that the urease activity detected in mammals is derived from commensal or infected microorganisms. Furthermore, regarding the relationship between urease and disease, see e.g.
Urinary tract stone disease is caused by Iris mirabilis infection, and in recent years, it has been suggested that Campylobacter pylori, which has strong urease activity, is involved in the onset and progression of chronic gastritis and gastric ulcer. [For example, J, of Clinical

(989)) However, regarding the pharmaceutical application of urease inhibitors, only attempts have been made to use acetohydroxamic acid as a therapeutic agent for urolithiasis. Cetraxate and tranexamic acid are known as substances with a structure relatively similar to the present invention, but these substances have protease inhibitory activities such as anti-plasmin activity, and also have anti-urease activity. substance is unknown.

。In addition, many drugs are known and sold as anti-ulcer agents. For example, representative examples include cetraxate hydrochloride, a protective anti-ulcer agent, and cimetidine, a histamine H2 receptor antagonist that has a strong gastric acid secretion suppressing effect.

化、抵抗性潰瘍の発生といった問題がある。Since the anti-ulcer activity of cetraxate hydrochloride is not necessarily satisfactory, especially for chronic ulcers, combination therapy with a gastric acid secretion suppressant such as cimetidine is required. In addition, cimetidine has a strong inhibitory effect on gastric acid secretion.
Although the ulcer healing rate has increased, side effects such as anti-androgen effects and agranulocytosis are known, and there are further problems such as ulcer recurrence, chronicity, and development of resistant ulcers.

Has strong inhibitory activity. The compound of the present invention is a conventionally known drug,
For example, unlike cetraxate and tranexamic acid, it strongly inhibits not only proteolytic enzymes but also urease. Therefore, the enzyme inhibitor obtained in the present invention not only acts as a hemostatic agent and an anti-inflammatory agent, but also has new functions, namely, inhibits Campylobacter-derived urease in the gastric mucosa,
It is also extremely useful as an anti-ulcer agent with a protective function.
