Epidemic keratoconjunctivitis (EKC) is a hazardous and highly contagious disease, with the potential to cause epidemic outbreaks in hospitals and other community settings. There are currently no approved drugs for human adenovirus (HAdV), the causative agent of EKC. To establish a novel drug screening system for ocular HAdV infections, we employed CRL11516, a non-cancerous but immortalized human corneal epithelial cell line. Brincidoforvir and 3'-deoxy-3'-fluorothymidine inhibit replication of HAdV species C type 1 (C1), C2, E4, and C6 to the same extent. This alternative assay system may allow for the evaluation of anti-HAdV activity and cell cytotoxicity of compounds within 2 days and without the need of the rabbit eye infection model.
