Leupeptin is produced by various species of Actinomycetes. It strongly inhibits proteolysis by plasmin, trypsin and papin. Leupeptin is well absorbed through oral route. Leupeptin has been known to cause various neuropathological changes in vivo resembling those of aging or neurodegenerative processes in the human brain, including the accumulation of neuronal processes and neuronal cytoskeletal abnormalities leading to neurofibrillary tangle (NFT)-like formations. In in vitro experiments, leupeptin protects the heart from myocardial stunning. Leupeptin was found to inhibit tumorigenesis in mouse skin induced by a single, noncarcinogenic dose of 7,12- dimethylbenz(a)anthracene followed by repeated application of croton oil. Tumors that had already been induced were scarcely affected by leupeptin.

Cetraxate is an oral gastrointestinal medication, mucosal protectant. Cetraxate might indirectly stimulate capsaicin-sensitive afferent nerves and increase mucosal blood flow, and that this may be a key mechanism underlying its gastroprotective action. Cetraxate prevents gastric mucosal blood flow decrease in H. pylori-infected patients. It is usually used to improve gastric mucosal lesion in acute gastritis or acute exacerbation of chronic gastritis and to treat gastric ulcer. The most commonly reported adverse reactions include constipation, rash, nausea, vomiting, dry mouth and diarrhea.

Camostat mesilate (FOY-305) is a synthetic f low-molecular weight protease inhibitor. It is able to inhibit trypsin, prostasin, matriptase and plasma kallikrein. In addition camostat attenuates airway epithelial sodium channel function and enhances mucociliary clearance. Camostat mesilate tablets (FOIPAN®) are approved in Japan and used for the treatment of remission of acute symptoms of chronic pancreatitis and postoperative reflux esophagitis.
