Synthesis and activity of pyrrolidinyl- and thiazolidinyl-dipeptide derivatives as inhibitors of the Tc80 prolyl oligopeptidase from Trypanosoma cruzi
摘要:
Pyrrolidinyl- and thiazolidinyl- dipeptide derivatives, featuring either a vinyl sulfone-, a 2-ketobenzothiazole-, a nitrile-, or a benzimidazole group at the C-terminus, were designed and synthesized as potential inhibitors of the prolyl-specific Tc80 proteinase from Trypanosoma cruzi, the agent of Chagas' disease. These compounds were evaluated in vitro towards the target enzyme which was classified as a serine protease belonging to the prolyl oligopeptidase family (EC 3.4.21.26). A peptidyl nitrile and two peptidyl alpha-ketobenzothiazoles were shown to be potent reversible and competitive inhibitors of Tc 80 proteinase, with K-i values in the range 38-219 nM, and compared advantageously with some known mammalian prolyl oligopeptidase inhibitors.

catalytic cascade reaction of α‐ketoacids and aldehydes is achieved using the title catalyst and water as the solvent. Fluorescence imaging shows that the catalyst is mainly distributed on the surface of emulsiondroplets. Optically active isotetronicacids can be obtained with this method and the emulsiondroplets are responsible for the high reactivity and enantioselectivity.
Compounds effective in inhibiting replication of Hepatitis C virus ("HCV") are described. This invention also relates to processes of making such compounds, compositions comprising such compounds, and methods of using such compounds to treat HCV infection.
