Development of Enterovirus anti-viral agents that target the viral 2C protein
ChemMedChem(2022)
Abstract
The enterovirus (EV) genus includes a number of important human and animal pathogens. EV-A71, EV-D68, poliovirus (PV), and coxsackievirus (CV) outbreaks have affected millions worldwide causing a range of upper respiratory, skin, neuromuscular diseases, including acute flaccid myelitis, and hand-foot-and-mouth disease. There are no FDA-approved anti-viral therapeutics for these enteroviruses. In this study, we describe novel broad spectrum anti-viral compounds targeting the conserved non-structural viral protein 2C that have low micro-molar to nanomolar IC50 values. The selection of resistant mutants resulted in amino acid substitutions in the viral capsid protein, implying a role for 2C in capsid assembly, as has been seen in PV. The assembly and encapsidation stages of the viral life cycle are not fully understood and the inhibitors reported here could be useful probes in understanding these processes.
