Different characterization techniques were used to inspect the formation of the NFs, which is followed by antiviral investigation against BCV as well as MTT assay using MDBK cells.Results: Core/shell NFs, ranging between 80– 330 nm with tiny thorn-like branches, were formed which attained an enhanced encapsulation efficiency (97.5 ± 0.53%, P< 0.05) and a dual controlled release (a burst release of 65% at 1 h and a sustained release up to > 24 h). The antiviral investigation of the formed NFs revealed a significant inhibition of 98.88 ± 0.16% (P< 0.05) with IC50 of 12.6 μM against BCV cells.Conclusion: The results introduced a new, time/cost-saving strategy for the synthesis of biodegradable NFs without the need for electric current or hazardous cross-linking agents. Moreover, it provided an innovative avenue for the discovery of drugs of herbal origin for the fight against SARS-CoV-2 infection.Keywords: acaciin, molecular docking, nanofibers, core-shell, BCV/SARS-COV-2 |
