Aligned with the national Healthy China strategy, the Laboratory is dedicated to comprehensively improving the health of the Chinese nation and achieving coordinated development between public health and economic and social progress. Focusing on the R&D of innovative nucleoside antiviral drugs, the Laboratory's main research lines encompass major scientific and technological tasks such as the in-depth elucidation of the mechanisms of action and targets of nucleoside antiviral drugs, the expansion of new indications for existing nucleoside antiviral drugs, the development of broad-spectrum antiviral drugs, and research on antiviral drug resistance and targeted antiviral drugs. By conducting in-depth studies on the mechanisms and targets of existing drugs, the Laboratory aims to propose original fundamental theories for antiviral drug R&D, break through cutting-edge technologies that restrict the field, and provide systematic solutions to major scientific and technological challenges.
