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 ...

The fusogenic state of Mayaro virus induced by low pH and by hydrostatic pressure

, 2006
Mayaro virus is an enveloped virus that belongs to the Alphavirus genus. To gain insight into the mechanism involved in Mayaro virus membrane fusion, we used hydrostatic pressure and low pH to isolate a fusion-active state of Mayaro glycoproteins.

Seroprevalence of Chikungunya and O'nyong‐nyong Viruses in Senegal, West Africa

Journal of Medical Virology, Volume 97, Issue 3, March 2025.
ABSTRACT Arthritogenic alphaviruses such as chikungunya (CHIKV) and o'nyong‐nyong (ONNV) viruses have shown capacity to cause widespread epidemics, with recurrent and sporadic outbreaks occurring throughout sub‐Saharan Africa. We analyzed the seroprevalence for CHIKV and ONNV in 470 non‐febrile subjects from three regions in Senegal (Sindia, 2018 ...
