Universal strategies and methodologies in broad-spectrum antiviral drug discovery

Virus infection is a serious threat to human health and social development. The increase in pandemics caused by emerging and re-emerging viruses highlights the urgent need for broad-spectrum antivirals. In this perspective, we highlight recent case studies and summarize the universal strategies and methodologies in broad-spectrum antiviral drug discovery from common targets, common steps in viral life cycle, universal strategies, and broad-spectrum molecules, hoping to provide valuable guidance for the current and future development of antiviral drugs.
