Abstract

A series of 2-oxopiperazine derivatives were designed from the pyrrolopiperazinone cell-based screening hit 4 as a dengue virus inhibitor. Systematic investigation of the structure-activity relationship (SAR) around the piperazinone ring led to the identification of compound (S)-29, which exhibited potent anti-dengue activity in the cell-based assay across all four dengue serotypes with EC50 < 0.1 μM. Cross-resistant analysis confirmed that the virus NS4B protein remained the target of the new oxopiperazine analogs obtained via scaffold morphing from the HTS hit 4.
