Structural Elucidation, Antioxidant Properties, and In Silico Molecular Docking of Schiff Base Complexes Derived from Naphthalene-1,8-diamine and Terephthalaldehyde

Indonesian Journal of Chemistry
By combining two mmol of naphthalene-1,8-diamine with one mmol of terephthalaldehyde, a TPAL-DAN ligand was synthesized. Six metal salts: Mn(II), Co(II), Ni(II), Cu(II), Zn(II), and Cd(II) were used to prepare six Schiff base complexes.

DPPH Radical Scavenging Reaction of Hydroxy- and Methoxychalcones

Bioscience, Biotechnology, and Biochemistry, 2006
The DPPH radical scavenging activity of 2',4',6'-trihydroxy- and 2'-hydroxy-4',6'-dimethoxychalcones carrying a 2,3- and 3,4-dihydroxylated, and 3,4,5-trihydroxylated B-ring was evaluated in alcoholic and non-alcoholic solvents. All test compounds scavenged more than two equivalent of radicals by a possible conversion to the corresponding B-ring ...

Stage‐Adaptive Janus Microneedle System for Redox‐Immune Regulation and Mitochondrial Protection in Infected Diabetic Wound Healing

Advanced Science, EarlyView.
ABSTRACT Infected diabetic wounds are sustained by a vicious cycle of hyperglycemia‐driven bacterial infection, persistent oxidative stress, and excessive inflammation, which collectively disrupt the ordered progression of tissue repair. Here, we engineered a stage‐adaptive Janus microneedle patch (MN‐FeSAC‐PPE) to enable a staged therapeutic process ...
