Adaptive changes in alphavirus mRNA translation allowed colonization of vertebrate hosts [PDF]

, 2012
Members of the Alphavirus genus are arboviruses that alternate replication in mosquitoes and vertebrate hosts. In vertebrate cells, the alphavirus resists the activation of antiviral RNA-activated protein kinase (PKR) by the presence of a prominent RNA

The Halogen Effect in [Cu(NHC)X] Compounds: A Case Study on the Anti‐Leishmania and Antiviral Activity of [Cu(IPr)X]

ChemistrySelect, Volume 10, Issue 31, August 15, 2025.
This study explores how changing halidesfrom Cl to Iinfluences ionic radius, antioxidant activity, and lipophilicity. These shifts significantly impact the biological potency of [Cu(IPr)X] compounds against Leishmania parasites and arboviruses. A strategic tweak in halogen identity paves the way for enhanced therapeutic performance in metal‐based drug ...
