  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.

  A series of 2-pyrazolyl quinolones has been designed and synthesized in 5-7 steps to optimize for both in vitro antimalarial potency and various in vitro drug metabolism and pharmacokinetics (DMPK) features. The most potent compounds display no cross-resistance with multidrug resistant parasite strains (W2) compared to drug sensitive strains (3D7), with IC50 (concentration of drug required to achieve

  已经设计并合成了一系列2-吡唑基喹诺酮类药物，分5-7个步骤进行了优化，以优化体外抗疟药功效以及各种体外药物代谢和药代动力学（DMPK）功能。与对药物敏感的菌株（3D7）相比，最有效的化合物与对多药耐药的寄生虫菌株（W2）没有交叉耐药性，IC50（达到最大最大生长抑制一半所需的药物浓度）值在15-33 nM之间。此外，该系列的成员保留了对耐阿托伐醌的寄生虫分离物（TM90C2B）的中等活性。所述的2-吡唑酰基系列显示出改善的DMPK特性，与先前报道的喹诺酮系列相比具有改善的水溶性，并且通过体外细胞毒性评估具有可接受的安全范围。
