一般說明

克拉霉素是一种大环内酯类抗生素，具有抗菌和抗炎作用。它是红霉素 A 的半合成 14 元衍生物，在酸性条件下抗降解。

應用

克拉霉素可用于-
  • 研究克拉霉素对动脉灌注兔左心室楔形制剂的 QT、Tp-e 和促心律失常事件的速率依赖性变化的影响
  • 表达 GFP（绿色荧光蛋白）的寄生虫的培养靶向顶质体，以进一步进行显微镜分析
  • NAB741 与克拉霉素在微量滴定板中的协同作用研究。

生化／生理作用

大环内酯类，如克拉霉素，通过与 50S 核糖体亚基结合，阻止细菌中的蛋白质合成。它还与其他核糖体蛋白结合，并阻止肽-dyl-tRNA 的易位。在难治性哮喘患者中，它能够调节白细胞介素 8（IL-8） 的水平，以及中性粒细胞在肺中的积聚和活化。因此，它可能被用作哮喘的附加疗法，以减少非嗜酸性气道炎症。

Patients with refractory asthma have persistent symptoms despite maximal treatment with inhaled corticosteroids and long-acting bronchodilators. The availability of add-on therapies is limited, and effective add-on therapies that target noneosinophilic airway inflammation are needed. Macrolide antibiotics, such as clarithromycin, have

Drug-induced torsades de pointes (TdP) often occurs during bradycardia due to reverse use-dependence. We tested the hypothesis that inhibition or enhancement of late sodium current (I(Na,L) ) could modulate the drug-induced reverse use-dependence in QT and T(p-e) (an index of
