Application

1,2,4-triazole and its derivatives are important structural moieties of many pharmaceutical drugs. Triazoles can also act as ligands to form coordination complexes with transition metal ions. Due to their electron-deficient nature, they exhibit excellent electron-transport and hole-blocking properties, making them promising organic materials in material science applications.

APOBEC3G (A3G) is a single-stranded DNA cytosine deaminase that functions in innate immunity against retroviruses and retrotransposons. Although A3G can potently restrict Vif-deficient HIV-1 replication by catalyzing excessive levels of G→A hypermutation, sublethal levels of A3G-catalyzed mutation may contribute to
