Cyclotheonamide
WebSep 1, 1993 · The macrocyclic peptide cyclotheonamide A (CtA), isolated from the marine sponge Theonella sp., represents an unusual class of serine protease inhibitor. A complex of this inhibitor with human alpha-thrombin, a protease central to the bioregulation of thrombosis and hemostasis, was studied by x-ray crystallography. WebMay 1, 2008 · The total synthesis of cyclotheonamide C (3), a macrocyclic pentapeptide incorporating an alpha-keto homoarginine (k-Arg) and a vinylogous dehydrotyrosine (V-deltaTyr) unit, has been achieved.
