Excessive autophagy plays a crucial role in cigarette smoking extract (CSE)-induced inflammation response and oxidative damage of respiratory epithelial cells. The components from Eclipta prostrata L. (CCE) have been shown to be beneficial for CSE-induced epithelial cells injury. However, whether its protection on CSE-stress injury is related to its regulation on autophagy remains still unclear. In this study, CCE, containing mainly wedelolactone of 45.88% and demethylwedelolactone of 23.74%, could improve significantly 10% CSE-induced cell viability of normal human bronchial epithelial (NHBE) cells using CCK-8 kit. We revealed that CCE could remarkably increase autophagic factors Beclin-1, Atg5, ATF4 proteins expression levels and the transformation of LC3-I to LC3-II. Addnl., CCE up-regulated significantly p-p16 and p-p21 phosphorylation levels whereas down-regulated p-p53 in NHBE cells. The changes of typical autolysosom and representative autophagosome in the presence of CCE or/and autophagy inhibitor chloroquine (CQ) were also observed by transmission electron microscopy. These data demonstrated that CCE reduced CSE-induced autophagy flux activation in NHBE cells. The blockade of CCE on autophagy flux contributes to its protection against CSE-induced NHBE cells damage, and CCE is promising to be combination therapeutic mols. to excessive autophagic damage in respiratory diseases. This study involved multiple reactions and reactants, such as 1,8,9-Trihydroxy-3-methoxy-6H-benzofuro[3,2-c]chromen-6-one (cas: 524-12-9Electric Literature of C16H10O7).
1,8,9-Trihydroxy-3-methoxy-6H-benzofuro[3,2-c]chromen-6-one (cas: 524-12-9) belongs to benzofurans derivatives. Benzofuran derivatives have shown many biological activities, including antifungal and antimicrobial properties, and acting as antagonists of H3 receptors and angiotensin II. In nature, benzofurans have occupied an important role among the plant phenols & several pharmacologically active compounds.Electric Literature of C16H10O7
