Abstract

The present invention discloses a new application of recombinant hirudin for preparing medicine for preventing and curing catarct.

Description

technical field [0001] The present invention relates to the new application of recombinant hirudin, especially the application in the field of pharmacy. Background technique [0002] Hirudin is a protein containing 65-66 amino acids extracted from the salivary glands of medical leeches. It is a single-chain polypeptide with a molecular weight of 7000u. The secondary structure makes this domain stable, and the linear C-terminal sequence is used to bind thrombin. As a specific inhibitor of thrombin, it has strong anticoagulant activity, can effectively prevent and treat disseminated intravascular coagulation, and has a significant effect on diseases such as cardiovascular thrombosis and cerebral thrombosis. Due to the limited source of natural hirudin, bioengineering technology is widely used to prepare recombinant hirudin. The two most widely used cell expression systems are Escherichia coli (E.coli) and Saccharomyces cerevisiae (S.cerevisiae). The preparation method of rec...
