  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.

  Novel extended side chain nitroimidazooxazine analogues featuring diverse linker groups between two aryl rings were studied as a potential strategy to improve solubility and oral activity against chronic infection by Mycobacterium tuberculosis. Both lipophilic and highly polar functionalities (e.g., carboxamide, alkylamine, piperazine, piperidine, but not sulfonamide) were well tolerated in vitro, and the hydrophilic linkers provided some solubility improvements, particularly in combination with pyridine rings. Most of the 18 compounds further assessed showed high microsomal stabilities, although in the acute infection mouse model, just one stilbene (6-fold) and two pyridine-containing acetylene derivatives (5-fold and >933-fold) gave in vivo efficacies notably superior to the clinical stage compound pretomanid (PA-824). The most efficacious analogue also displayed outstanding in vivo activity in the stringent chronic model (up to 24-fold better than the drug delamanid and 4-fold greater than our previous best phenylpyridine candidate), with favorable pharmacokinetics, including good oral bioavailability in the rat.
