Scavenging of hydroxyl radicals
WebApr 13, 2024 · The hydroxyl radicals (·OH) and superoxide anions (O 2.−) scavenging effects of the hydrogels were subsequently evaluated. The ·OH scavenging ability was assessed via Fenton reaction. Briefly, 10 mM FeSO 4 and 10 mM H 2 O 2 were added to the hydrogel samples (Φ 5 mm × 4 mm). WebAbstract: Novel hydroxylated benzylideneamino imidazole derivatives were synthesized and their radical scavenging activity was assessed against DPPH and hydroxyl radicals. In the DPPH assay, most of the synthesized compounds showed an IC50 in the range 3.2μM⩽IC50⩽8.4μM, lower than the reference compound trolox (IC50=9.5μM) or the …
