Abstract
![]()
The SARS-CoV-2 pandemic is currently causing an unprecedented
global
health emergency since its emergence in December 2019. In December
2021, the FDA granted emergency use authorization to nirmatrelvir,
a SARS-CoV-2 main protease inhibitor, for treating infected patients.
This peptidomimetic is designed with a nitrile warhead, which forms
a covalent bond to the viral protease. Herein, we investigate nirmatrelvir
analogs with different warheads and their inhibitory activities. In
addition, antiviral activities against human alphacoronavirus 229E
was also investigated along with a cell-based assay. We discovered
that the hydroxymethylketone and ketobenzothiazole warheads were equipotent
to the nitrile warhead, suggesting that these analogs can also be
used for treating coronavirus infections.
