Abstract

PURPOSE:To obtain an azidothymidine-protein complex bonded by a novel bond site. CONSTITUTION:CHO at the 5'-position of 3'-deoxy-3'-azidothymidine(AZT) shown by formula I is reacted with amino group of protein to form a Schiff base, which is then treated with a mild reducing agent to give AZT-protein to give AZT-protein complex shown by formula II. Monoclonal antibody, polyclonal antibody of mouse, human, rat, etc., serum albumin, lysozyme, fibrin, etc., of various animals may be cited as the protein. When an antiviral antibody is used as the protein, the complex is expected to have effects as missile therapy having antiviral action.

[Prior Art] AZT itself has been put into practical use as an antiviral agent, but it has many problems, including side effects such as severe bone marrow cell suppression and neutropenia. Therefore, research is being carried out on proteins carrying AZT.For example, if an anti-viral antibody is used as a protein, it can be expected to be effective as a missile therapy drug with anti-viral effects. Additionally, direct binding to an antiviral antibody may impair the activity of the antibody, but in that case, it is possible to use a certain protein as a spacer, and complexes with appropriate proteins bound are also being studied.
