Abstract
This study focused on the development of novel chloroquine derivatives as potential antiviral agents against SARS-CoV-2. By modifying the 7-position of chloroquine using Sonogashira and Buchwald cross-coupling reactions, a series of compounds were synthesized. In vitro evaluations identified several derivatives with promising antiviral activity, with compound 9d exhibiting strong inhibitory effects and a favorable selectivity index. These results suggest that the derivatives provide a promising basis for further optimization and development as antiviral drugs. This work highlights the potential of structural modifications to improve the effectiveness of chloroquine derivatives. Given the ongoing challenges of COVID-19, these novel compounds deserve further investigation to determine their mechanisms of action and therapeutic value. This study provides important insights into antiviral drug development and highlights the need for continued efforts to optimize existing drug scaffolds in the fight against emerging viral threats.
