bromide. The structures were confirmed by spectroscopic and crystallographic studies and further screened in vitro for their free radical scavenging activities. Preliminary assessment results show that, among the synthesized series, compounds 5c, 5d, 5f, 5i, 5j, 5l, and 5m have potent antioxidant activities. Docking studies reveal that the ligands 5e, 5f, 5m, and 5q bind to superoxide dismutase at the
氧化应激是神经发生性疾病的重要原因。使用无副作用的可靠抗氧化剂进行治疗是克服此类疾病的潜在工具。这项研究的目的是探索新型有效的抗氧化剂及其机理。在此背景下,手稿展示了绿色的合成方法,用于合成一系列新型噻吩-吡唑杂化物5(a–m)至[3 + 2]查耳酮3(a–g)环化和盐酸苯肼4(a–b)在四丁基溴化铵存在下的柑橘提取液中)。通过光谱和晶体学研究证实了该结构,并进一步在体外对其自由基清除活性进行了筛选。初步评估结果表明,在合成的系列中,化合物5c,5d,5f,5i,5j,5l和5m具有有效的抗氧化活性。对接研究表明,配体5e,5f,5m和5q在Cu-Zn域结合超氧化物歧化酶,从而增加其活性并减少活性氧;因此,这些配体可能是更好的抗氧化剂分子,可以降低并调节体内的氧化应激。
