Enviroxime (LY 122772) is a selective phosphatidylinositol 4-kinase type IIIβ (PI4KB, PI4KIIIβ) inhibitor (IC50 = 60 nM/PI4KB vs. 1.917 µM/PI4KA) with antiviral potency against enteroviruses, including rhinovirus (RV plaque reduction IC50 ≤40 ng/mL; HeLa), poliovirus (PV), coxsackievirus (CV). PI4KB is a host factor essential for enterovirus replication, mutations in viral 3A protein that recruits PI4KB to the replication sites result in enviroxime resistance. Enviroxime is also reported to impede PI4K-independent hepatitis C (HCV) replication at least partially by an inhibitory effect on PI3Ks.
