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.

The activity of the skin TAME (p-toluene-sulfonyl-L-arginine methyl ester) esterase had increased almost 2.5 times at 24 hr after 0.3% croton oil treatment. The TAME esterase activity was significantly inhibited by addition of leupeptin, 0.1 mg/ml, and it was progressively inhibited by higher concentrations of leupeptin. The activity was less than 10% of the control in the presence of leupeptin, 2.5 mg/ml.
