anchored to the β-lactam ring ensured an adequate antioxidant potency. New compounds, efficiently combining in one structure antioxidant and antibacterial activity, may provide a promising basis for the development of new leads useful in adverse clinical conditions such as in cystic fibrosis patients, in whom colonization by MRSA and epithelial damage by chronic pulmonary oxidative stress take place
一系列具有抗菌活性的N-甲硫基-β-内酰胺类被彻底评估为抗氧化剂。我们发现仅锚定至β-内酰胺环的多酚部分的存在确保了足够的抗氧化剂效力。在一种结构中有效结合抗氧化剂和抗菌活性的新化合物可能为开发可用于不良临床状况的新线索提供有希望的基础,例如在囊性纤维化患者中,MRSA会引起定植,慢性肺氧化应激会导致上皮损伤地方。
