Activity  [Ref.36739680]Peptides 7 at 200 μM exhibited good inhibitions of DENV-1 (67.17%) plaque formation, but much lower inhibitions were observed against DENV-2 to 4 ranging from 28.31 to 37.73%; peptide 7 (200 μM) showed good direct virus-inactivating effects against DENV-3 (64.03%) and DENV-4 (78.76%) whereas lower inhibitions were observed against DENV-1 (32.66%) and DENV-2 (47.84%); peptide 7 demonstrated highly significant inhibition of DENV-4 at 84.82% during post-infection, much lower inhibitions were observed against DENV-2 and 3 at 9.13% and 2.24%; Peptide 7 was observed to inhibit DENV-4 replications significantly with reductions of RNA copy numbers by 77.01%.
