  Identification, Design and Biological Evaluation of Heterocyclic Quinolones Targeting Plasmodium falciparum Type II NADH:Quinone Oxidoreductase (PfNDH2)

  摘要：

  Following a program undertaken to identify hit compounds against NADH:ubiquinone oxidoreductase (PfNDH2), a novel enzyme target within the malaria parasite Plasmodium falciparum, hit to lead optimization led to identification of CK-2-68, a molecule suitable for further development. In order to reduce ClogP and improve solubility of CK-2-68 incorporation of a variety of heterocycles, within the side chain of the quinolone core, was carried out, and this approach led to a lead compound SL-2-25 (8b). 8b has IC(50)s in the nanomolar range versus both the enzyme and whole cell P. falciparum (IC50 = 15 nM PfNDH2; IC50 = 54 nM (3D7 strain of P. falciparum) with notable oral activity of ED50/ED90 of 1.87/4.72 mg/kg versus Plasmodium berghei (NS Strain) in a murine model of malaria when formulated as a phosphate salt. Analogues in this series also demonstrate nanomolar activity against the bc(1) complex of P. falciparum providing the potential added benefit of a dual mechanism of action. The potent oral activity of 2-pyridyl quinolones underlines the potential of this template for further lead optimization studies.

  通过配体促进的CC键活化来转化芳基酮。

  摘要：

  芳族亲电试剂（芳基卤化物，芳基醚，芳基酸，芳基腈等）与亲核试剂的偶联是合成芳基化合物的核心方法。由于芳基酮的丰度，通过碳-碳键活化以类似方式进行芳基酮的转化可大大扩展合成芳基化合物的工具箱。这种方法的探索性研究通常基于环应变释放和螯合辅助引发的碳-碳裂解，并且产物也仅限于特定的结构基序。在这里，我们报告了一种配体促进β-碳消除的策略，以激活碳-碳键，这导致芳基酮发生一系列转化，从而生成有用的芳基硼酸酯，以及联芳基，芳基腈和芳基烯烃。吡啶-恶唑啉配体的使用对于这种催化转化至关重要。据报道，通过简单的一锅操作，芳基酮的克级硼酸酯化反应。该策略的潜在效用还通过丙磺舒，阿达帕林和脱氧雌酮，芬芳类香囊素和载脂蛋白的天然产物的晚期药物分子多样化而得到证明。

  Novel imidazo[4,5-c]quinolin-2-ones were synthesized and evaluated in asexual blood stage and late stage gametocyte assays of Plasmodium falciparum, a major causative agent of malaria. The design of these compounds is based on a recently identified lead compound from a high throughput screen. A concise synthesis was developed that allowed for generation of analogues with substitution around both the
