Journal ArticleDOI
Antiviral activity of silymarin against chikungunya virus
Rafidah Lani,Pouya Hassandarvish,Chun Wei Chiam,Ehsan Moghaddam,Justin Jang Hann Chu,Kai Rausalu,Andres Merits,Stephen Higgs,Dana L. Vanlandingham,Sazaly Abu Bakar,Keivan Zandi +10 more
TL;DR: Silymarin exhibited significant antiviral activity against chikungunya virus, reducing both CHIKV replication efficiency and down-regulating production of viral proteins involved in replication.
Journal ArticleDOI
The Antiviral Alkaloid Berberine Reduces Chikungunya Virus-Induced Mitogen-Activated Protein Kinase Signaling
Finny S. Varghese,Bastian Thaa,Siti Naqiah Amrun,Diane Simarmata,Kai Rausalu,Tuula A. Nyman,Andres Merits,Gerald M. McInerney,Lisa F. P. Ng,Tero Ahola +9 more
TL;DR: Berberine is effective in multiple cell types against a variety of CHIKV strains, also at a high multiplicity of infection, consolidating the potential of berberine as an antiviral drug and highlighting the importance of the MAPK signaling pathways in the alphavirus infectious cycle.
Journal ArticleDOI
Reverse genetic system, genetically stable reporter viruses and packaged subgenomic replicon based on a Brazilian Zika virus isolate.
Margit Mutso,Sirle Saul,Kai Rausalu,Olga Y Susova,Eva Žusinaite,Suresh Mahalingam,Andres Merits +6 more
TL;DR: Efficient reverse genetic systems, genetically stable marker viruses and packaged replicons offer significant improvements for biological studies of ZIKV infection and disease, as well as for the development of antiviral approaches.
Journal ArticleDOI
Construction, properties, and potential application of infectious plasmids containing Semliki Forest virus full-length cDNA with an inserted intron.
TL;DR: An infectious plasmid of SFV, pCMV-SFV4, was constructed; its toxic effect was eliminated by intron insertion in the capsid protein encoding region and it produced virus with properties identical to those of wild-type SFV.
Journal ArticleDOI
Obatoclax Inhibits Alphavirus Membrane Fusion by Neutralizing the Acidic Environment of Endocytic Compartments
Finny S. Varghese,Kai Rausalu,Marika Hakanen,Sirle Saul,Beate M. Kümmerer,Petri Susi,Andres Merits,Tero Ahola +7 more
TL;DR: Obatoclax is a novel inhibitor of endosomal acidification that prevents viral fusion and that could be pursued as a potential broad-spectrum antiviral candidate.
