N-arylpyrimidinamine (NAPA) compounds are broadly acting inhibitors of human cytomegalovirus infection and spread.

ABSTRACT: Human cytomegalovirus (HCMV) is a β-herpesvirus that contributes to the disease burden of immunocompromised and immunomodulated individuals, including transplant recipients and newborns. The FDA-approved HCMV drugs can exhibit drug resistance and severe side effects including bone marrow toxicity, gastrointestinal disruption, and nephrotoxicity. In a previous study, we identified the N-arylpyrimidinamine (NAPA) compound series as a new class of HCMV inhibitors that target early stages of infection. Here we describe the inhibitory activity of two potent NAPA analogs, MBXC-4336 and MBX-4992, that broadly block infection and spread. MBXC-4336 and MBX-4992 effectively inhibited infection by diverse HCMV strains and significantly prevented virus spread in fibroblast and epithelial cells as eval
