dc.description.abstractAntiviral therapy is crucial for the circumvention of viral epidemics. The unavailability of a specific antiviral drug against the chikungunya virus (CHIKV) disease has created an alarming situation to identify or develop potent chemical molecules for remedial management of CHIKV. In the present investigation, in silico studies of dihydrorugosaflavonoid derivatives (5a-f) with non-structural protein-3 (nsP3) were carried out. nsP3 replication protein has recently been considered as a possible antiviral target in which crucial inhibitors fit into the adenosine-binding pocket of the macrodomain. The 4?-halogenated dihydrorugosaflavonoids displayed intrinsic binding with the nsp3 macrodomain (PDB ID: 3GPO) of CHIKV. Compounds 5c and 5d showed docking scores of-7.54 and-6.86 kcal mol-1, respectively. Various in vitro assays were performed to confirm their (5a-f) antiviral potential against CHIKV. The non-cytotoxic dose was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay and was found to be <100 ?M. The compounds 5c and 5d showed their inhibitory potential for CHIKV, which was determined through cytopathic effect assay and plaque reduction assay, which show inhibition up to 95 and 92% for 70 ?M concentration of the compounds, respectively. The quantitative real-Time polymerase chain reaction assay result confirmed the ability of 5c and 5d to reduce the viral RNA level at 70 ?M concentration of compounds to nearly 95 and 93% concentration, respectively, in cells with CHIKV infection. Further, the CHIKV-inhibitory capacity of these compounds was corroborated by execution of immunofluorescence assay. The executed work will be meaningful for the future research of studied dihydrorugosaflavonoids against prime antiviral entrants, leading to remedial management to preclude CHIKV infection.
