Chlorinated biscoumarins inhibit chikungunya virus replication in cell-based and animal models

Biscoumarin derivatives were evaluated for antiviral activity against chikungunya virus (CHIKV), a re-emerging mosquito-borne alphavirus with no approved treatment. Compounds 3 and 4 demonstrated potent in vitro antiviral efficacy, with EC₅₀ values of 2.85 ± 0.42 µM and 3.08 ± 0.45 µM (SI > 20) f...
