TL;DR
This study explores the antiviral potential of a plant's rhizome against human adenoviruses using both computer modeling and lab experiments.
Contribution
The study identifies bioactive metabolites in Hellenia speciosa rhizome with potential anti-adenoviral activity through molecular docking and in vitro testing.
Findings
Methanolic extract of Hellenia speciosa rhizome showed potent antiviral effects with low cytotoxicity.
Molecular docking revealed strong interactions between selected metabolites and adenoviral DNA polymerase.
Ethanolic extract also demonstrated notable antiviral activity with a favorable therapeutic window.
Abstract
Human adenoviruses (HAdVs) cause a wide range of clinical diseases, yet effective antiviral therapies remain limited. Natural products, particularly medicinal plants, offer potential sources of antiviral agents. This study aimed to evaluate the antiviral potential of Hellenia speciosa (J.Koenig) S.R.Dutta [syn. Costus speciosus (J.Koenig) Sm.; Costaceae] rhizome against HAdVs using both in vitro and in silico approaches. Rhizome extracts were tested on Vero cells to assess cytotoxicity and antiviral activity. GC–MS identified bioactive metabolites, which were screened against adenoviral DNA polymerase using molecular docking. Docking predicted strong interactions of selected metabolites with the viral polymerase, guiding selection for in vitro assays. The methanolic extract exhibited low cytotoxicity and potent antiviral effects, while the ethanolic extract also showed notable…
