  Inhibitory effect of novel 5-O-acyl juglones on mammalian DNA polymerase activity, cancer cell growth and inflammatory response

  摘要：

  We previously found that vitamin K(3) (menadione, 2-methyl-1,4-naphthoquinone) inhibits the activity of human mitochondrial DNA polymerase gamma (pol gamma). In this study, we focused on juglone (5-hydroxy-1,4-naphthoquinone), which is a 1,4-naphthoquinone derivative, and chemically synthesized novel juglones conjugated with C2:0 to C22:6 fatty acid (5-O-acyl juglones). The chemically modified juglones enhanced mammalian pol inhibition and their cytotoxic and anti-inflammatory activities. The juglone conjugated with oleic acid (C18:1-acyl juglone) showed the strongest inhibition of DNA replicative pol alpha activity and human colon carcinoma (HCT116) cell growth in 10 synthesized 5-O-acyl juglones. C12:0-Acyl juglone was the strongest inhibitor of DNA repair-related pot lambda, as well as the strongest suppression of the production of tumor necrosis factor (TNF)-alpha production induced by lipopolysaccharide (LPS) in the compounds tested. Moreover, this compound caused the greatest reduction in 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced acute inflammation in mouse ears. C12:0- and C18:1-Acyl juglones selectively inhibited the activities of mammalian pol species, but did not influence the activities of other pols and DNA metabolic enzymes tested. These data indicate that the novel 5-O-acyl juglones target anti-cancer and/or anti-inflammatory agents based on mammalian pot inhibition. Moreover, the results suggest that acylation of juglone is an effective chemical modification to improve the anti-cancer and anti-inflammation of vitamin K(3) derivatives, such as juglone.

  4-naphthoquinone presented strong activity, e.g., 2-bromo-5-hydroxy-1,4-naphthoquinone, which exhibited inhibition at an MIC of 16 µg/mL in S. aureus, and 2-chloro-5,8-dihydroxy-1,4-naphthoquinone, with an MIC of 2 µg/mL in C. krusei. These compounds showed higher activity against fungi, but the antibacterial activities were very low. The study of structure–activity relationships is very important in the search

  1,4-萘醌衍生物的合成备受关注，因为这些化合物作为抗疟疾，抗菌，抗真菌和抗癌剂具有很强的活性。合成了一系列50种萘醌衍生物，并使用肉汤微稀释法评估了其对大肠杆菌，铜绿假单胞菌，粪肠球菌，金黄色葡萄球菌，克鲁斯假丝酵母，副念珠菌和新隐球菌的抗菌和抗真菌活性。该念珠菌种是最易感的微生物。1,4-萘醌的卤素衍生物具有很强的活性，例如2-溴-5-羟基-1,4-萘醌，在金黄色葡萄球菌和2-chloro-5中的MIC为16 µg / mL时表现出抑制作用，8-二羟基-1,4-萘醌，在克鲁氏梭菌中的MIC为2 µg / mL 。这些化合物显示出较高的抗真菌活性，但抗菌活性非常低。由于药库的限制，结构-活性关系的研究对于寻找新的抗微生物药物非常重要。
