摘要： The present invention relates to peptides that can inhibit the infection of HIV, and more particularly, to peptides consisting of less than 30 amino acids which can introduce a helix capping motif into a peptide derived from C-terminal helical region (its 628-646th amino acid region) of gp41, an envelope glycoprotein of HIV, as well as consisting of the symmetrical bivalent peptide through the introduction of a branched amino acid, Fmoc-Lys(Fmoc)-OH at C-terminus of its peptide, and induce a more stable helical structure thus inhibiting the infection of HIV.

摘要： The present invention relates to a method for detecting a substance having an activity to inhibit HIV infection rapidly, economically and safely. The present invention uses the characteristics that if a function of transmembrane protein gp41 of HIV is inhibited, HIV infection is also inhibited, and therefore the function of gp41 depends on the interaction between two helical structures of gp41. The method of the present invention is to detect a substance to inhibit HIV infection by an immunoassay using the interaction between the variant protein Trx-N, which is prepared by binding the N-terminal helical domain of gp41 to Trx (thioredoxin) and the variant protein GST-C, which is prepared by binding the C-terminal helical domain of gp41 with GST-C (Glutathione S-transferase). This immunoassay can be used for automatic detection of the substance to inhibit the activity of gp41 can be carried out by the method. As a result, it is possible to investigate HIV infection-inhibiting activity of a number of previously known compounds or natural compounds, and it can attribute to the development of therapeutic agent of HIV infection.

摘要： The present invention relates to a method for screening an inhibitory agent of HBV proliferation by measuring the interaction (binding strength) between capsid protein and surface protein, necessary for the proliferation of HBV, by using cellular imaging, more precisely a method for measuring changes on cellular imaging caused by the interaction between a fusion protein containing PreS domain of HBV surface protein and PH (Pleckstrin homology) domain sequence and a fusion protein containing capsid protein and fluorescence protein (GFP) interacting with the said fusion protein. The method of the present invention detecting the interaction between proteins necessary for HBV proliferation at cellular level can be effectively used for the screening of a novel inhibitory agent of HBV proliferation at cellular level.
