However, when producing E-64 by dairy fermentation,
It is limited to sedimentary culture using bran medium, etc., and the yield is low. In addition, E-64 is a neutral substance in which trans-epoxysuccinilic acid, L-leucine, and the amine component agmatine are combined, but when producing it by synthesis, it requires many steps to introduce agmatine. This results in an increase in costs. Furthermore, E-64 has a histamine-like side effect of increasing vascular permeability in venules. The present inventors have conducted extensive research aimed at developing a thiol protease inhibitor that is easy to synthesize, has an effect comparable to that of E-64, and has no side effects. The present invention was completed based on the discovery that the trans-epoxysuccinyl amino acid derivative obtained by this method has a specific and strong thiol protease inhibitory effect comparable to that of E-64.
