Oxoquinolineribonucleosides 1a-j were prepared. These substances were screened for antiviral activity on HSV-1 virus infection, assessed by virus yield assay. The chlorosubstituted ribonucleosides 1b and 1g were the best inhibitors of HSV-1 yield with EC50 of 1.5 ± 0.06 μM and 1.7 ± 0.08 μM, respectively. Compound 1b presented the best selectivity index (SI) with an SI value of 1000.
