pharmacophores may lead to an increase of the antioxidant activity. Therefore, we synthesized four series of new hybrid molecules bearing the quinazolin-4-one and phenol scaffolds. Their antioxidant potential was evaluated in vitro, considering different possible mechanisms of action: hydrogen atom transfer, ability to donate electrons and metal ions chelation. Theoretical quantum and thermodynamical calculations
考虑到活性氧(ROS)和氮(RNS)对人体造成的重要损害,对比已知的天然和合成抗氧化剂具有更好功效的新治疗剂的需求至关重要。 Quinazolin-4-ones 以其广泛的生物活性而闻名,酚类化合物显示出重要的抗氧化作用。连接两个活性药效团可能会导致抗氧化活性增加。因此,我们合成了四个系列的带有喹唑啉-4-一和苯酚支架的新型杂化分子。它们的抗氧化潜力在体外进行了评估,考虑了不同可能的作用机制:氢原子转移、提供电子的能力和金属离子螯合。还进行了理论量子和热力学计算。一些化合物,尤其是邻二酚类化合物,比抗坏血酸和 Trolox 具有更强的抗氧化作用。
