も研究されている。[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.
