制备方法与用途

生物活性

HQNO(2-羟基-4-羟喹啉-N-氧化物)是一种由铜绿假单胞菌分泌的天然喹诺酮。它也是电子传递链的有效抑制剂,对呼吸链中的泛醇-亚铁色素c还原酶区段(Complex III)的Kd值为64 nM。在50 μM menadione存在下,HQNO还是细菌和线粒体的Type II NADH : quinone氧化还原酶(NDH-2)抑制剂,在同样条件下其IC50值为7.3 μM。

体外研究

HQNO是多种生物中线粒体型II NADH:醌氧化还原酶(NDH-2)的强效抑制剂,包括酵母脂质分解菌 Yarrowia lipolytica、酿酒酵母 Saccharomyces cerevisiae、氧化葡萄糖酸杆菌 Gluconobacter oxydans、隐孢子虫 Toxoplasma gondii、疟原虫 Plasmodium falciparum 和金黄色葡萄球菌 S. aureus。HQNO靶向NDH-2的Q位点。

HQNO浓度分别从0 μM至100 μM和0 μM至300 μM变化,用于野生型(WT)及突变体I379E Candida thermarum NDH-2测定IC50值。在400 μM menadione存在下,WT NDH-2的IC50值为10.5±1.3 μM HQNO。在50 μM menadione存在的条件下,HQNO IC50值略微下降至7.3±1.2 μM,并且>50 μM HQNO导致近完全抑制(约15%残留活性)。

    名称:
    Chemical Modification and Detoxification of the Pseudomonas aeruginosa Toxin 2-Heptyl-4-hydroxyquinoline N-Oxide by Environmental and Pathogenic Bacteria
    摘要:
    2-Heptyl-4-hydroxyquinoline N-oxide (HQNO), a major secondary metabolite and virulence factor produced by the.opportunistic pathogen Pseudomonas aeruginosa, acts as a potent inhibitor of-respiratory electron transfer and thereby affects host cells as well as microorganisms. In this study, we demonstrate the previously unknown capability of environmental and pathogenic bacteria to transform and detoxify this compound. Strains of Arthrobacter and Rhodococcus spp. as well as Staphylococcus aureus introduced a hydroxyl group at C-3 of HQNO, whereas Mycobacterium abscessus, M. fortuiturn, and M.smegmatis. performed An O-methylation, forming 2-hepty1-1-inethoxy-4-okoquin.Oline as the initial metabolite. Bacillus spp. produced the glycosylated,derivative, 2-hepty1-1-(beta-D-glucopyranosydy1)-4-oxoquinoline. Assaying the effects of these metabolites on cellular respiration and on quinol oxidase activity of membrane fractions revealed that their EC50 values were up tot orders of magnitude higher than that of HQNO: Furthermore, cellular levels of reactive oxygen species were significantly lower in the preience of the metabolites than under the influence of HQNO. Therefore, the capacity to transform HQNO should lead to a competitive, advantage against P. aeruginosa, Our findings contribute new insight into the metabolic diversity of bacteria and add another layer of complexity to the metabolic interactions which likely contribute to shaping polymicrobial communities Comprising P. aeruginosa.

    摘要:
    烷基羟基喹啉N-氧化物(AQNOs)是由机会细菌病原体铜绿假单胞菌(Pseudomonas aeruginosa)产生的抗生素化合物,它们是烷基喹诺酮(AQ)生物合成途径的产物,还产生群体感应分子2-庚基-4(1H)-喹诺酮(HHQ)和2-庚基-3-羟基-4(1H)-喹诺酮(PQS)。尽管已经阐明了HHQ和PQS的酶促合成方法,但是合成AQNOs的途径仍然难以捉摸。在这里,我们报道了AQNO生产的关键酶PqsL,该酶在结构上类似于A类黄素单加氧酶,例​​如对羟基苯甲酸酯3-羟化酶(pHBH)和3-羟基苯甲酸酯6-羟化酶。但是,我们发现与相关的酶不同,PqsL羟基化了一个芳族胺基,并且它不使用NAD(P)H作为共底物,但出乎意料地需要减少黄素作为电子供体。我们还观察到,PqsL对AQ途径的中心中间体2-氨基苯甲酰乙酸酯(2-ABA)有活性,并形成不稳定的化合物2-羟基氨基苯甲酰乙酸酯,它比2
