PROCCESS FOR PRODUCING THROMBIN INHIBITORS BASED ON AMINO ACID SEQUENCE OF HIRUDINE AND PHARMACEUTICAL COMPOSITIONS COMPRISING SAME

摘要

A thrombin inhibitor comprising a first bulky hydrophobic portion interacting with the catalytic site of thrombin responsible for proteolysis and a second portion at least maintaining the hydrophobic and acidic character of amino acids 55 to 60 of native hirudin at the C-terminal non-catalytic region of N-acetyl-hirudin45-65. Between the first and second portions is a divalent linker moiety having a chain length of at least 10 carbon atomes. Preferably, the bulky hydrophobic portion comprises at least one amino acid of D-configuration. The compounds are useful in the treatment of thrombotic disorders.
