    摘要:
    由于当前抗疟疗法存在耐药性的威胁,因此需要开发新的抗疟药。为了发现新的抗疟化学型,我们针对恶性疟原虫无性寄生虫筛选了 Janssen Jumpstarter 文库,并鉴定了 7- N-取代-3-恶二唑喹诺酮命中类别。我们建立了构效关系并优化了抗疟功效。优化的类似物 WJM228 ( 17 )在体外表现出强大的代谢稳定性,尽管水溶性有限。正向遗传抗性研究发现,WJM228 靶向细胞色素b (cyt b ) 的 Q位点,细胞色素 b 是线粒体电子传递链 (ETC) 的重要组成部分,对于嘧啶生物合成至关重要,也是已确定的抗疟靶点。针对耐药寄生虫的分析证实,WJM228 具有对 Q o位点的抗性,但对 Q 位点突变没有抵抗力,并且在生物传感器测定中,它被证明可以通过抑制细胞色素b来影响 ETC。与其他 cyt b靶向抗疟药一致,WJM228 可以预防伯氏疟原虫疟疾小鼠模型中红细胞前寄生虫和雄配子的

  • DISCOVERY OF NOVEL ANTI-INFECTIVES FOR GRAM NEGATIVE PATHOGENS

    Burkholderia pseudomallei (Bp) and Burkholderia mallei (Bm) are Tier-1 select pathogens that cause highly lethal human infections with limited therapeutic options. Intercellular spread is a hallmark of Burkholderia pathogenesis and its prominent ties to virulence make it an attractive therapeutic target. We developed a high-throughput cell-based phenotypic assay and screened ˜220,000 small molecules for their ability to disrupt intercellular spread by Burkholderia thailandensis , a BSL-2 surrogate for these pathogens. 268 hits were identified, and cross-species validation found 32 hits that also disrupt intercellular spread by Bp and/or Bm. In a fulminant murine model of respiratory melioidosis, treatment with a number of these agents was significantly more effective than ceftazidime, the current drug of choice, for improving patient survival and decreasing bacterial counts in major organs.

    Previous quantitative and qualitative structure-activity studies in antibacterial monosubstituted 1-ethyl-1,4-dihydro-4-oxoquinoline-3-carboxylic acids prompted us to synthesize the 6,7,8-polysubstituted compounds. In this paper, the preparation and antibacterial activity of the 6,7- and 7,8-disubstituted compounds and their derivatives are described. Among these compounds, 1-ethyl-6-fluoro-1,4-di
