  Discovery of 3-(3-cyano-4-pyridyl)-5-(4-pyridyl)-1,2,4-triazole, FYX-051-a xanthine oxidoreductase inhibitor for the treatment of hyperuricemia

  摘要：

  Our previous study identified 2-[2-(2-methoxy-ethoxy)-ethoxy]-5-[5-(2-methyl-4-pyridyl)-1H-[1,2,4]-triazol-3-yl]-benzonitrile (2) as a safe and potent xanthine oxidoreductase (XOR) inhibitor for the treatment of hyperuricemia. Here, we synthesized a series of 3,5-dipyridyl-1,2,4-triazole derivatives and, in particular, examined their in vivo activity in lowering the serum uric acid levels in rats. As a result, we identified 3-(3-cyano-4-pyridyl)-5-(4-pyridyl)-1,2,4-triazole (FYX-051, compound 39) to be one of the most potent XOR inhibitors; it exhibited an extremely potent in vivo activity, weak CYP3A4-inhibitory activity and a better pharmacokinetic pro. le than compound 2. Compound 39 is currently being evaluated in a phase 2 clinical trial. (C) 2009 Elsevier Ltd. All rights reserved.

  structure on using isomeric ligands had a significant impact on the magnetic properties of compounds 1 and 2. Magnetic studies revealed that 1 and 2 exhibit slow magnetic relaxation behaviours under a zero direct-current field exhibiting effective energy barriers (Ueff) of 53.5 K and 132.6 K, respectively, wherein compound 2 possesses the highest Ueff in nine-coordinated Dy2 compounds.

  crucial to promote axiality to enhance easy-axis magnetic anisotropy. Two mononuclear DyIII compounds with each DyIII being nine-coordinated, namely, [(C12H10N5O)Dy(NO3)2(H2O)2]·C2H5OH (1) and [(C12H10N5O)Dy(NO3)2(C2H5OH)2]·H2O (2) (HL = N3-(2-pyridoyl)-4-pyridinecarboxamidrazone), have been prepared through controlling the amount of C2H5OH and H2O solvents. Geometry modulations were realized by interchanging

  增强轴向性以增强易轴磁各向异性至关重要。两个单核DyIII化合物，每个DyIII具有九个配位，即[（C12H10N5O）Dy（NO3）2（H2O）2]·C2H5OH（1）和[（C12H10N5O）Dy（NO3）2（C2H5OH）2]·H2O （2）（HL = N3-（2-吡啶基）-4-吡啶甲酰胺基酮），是通过控制C2H5OH和H2O溶剂的量制备的。通过交换配位溶剂和晶格溶剂来实现几何调制，因此更接近于1到2的带帽正方形反棱镜的构型。值得注意的是，磁性研究表明，化合物1的磁化强度没有缓慢的磁弛豫，而化合物2的单分子磁体（ SMM）在九个协调的DyIII SMM中没有最高能垒（203.11 K）的静态磁场的情况下的行为。进行了从头算的计算来阐明这种不同的性能，这表明沿磁轴的较大电荷分布和在赤道平面内的较低电荷分布的组合产生了较强的易轴配体场，从而增强了磁性能，这进一步与结构对称。此外，提出了一

Finally, an unusual C–H⋯Pb interaction was identified to be attractive despite its long distance (>3.7 Å).

  The isoniazid-derived hydrazones 2-pyridinecarbaldehyde-(HPCIH), 2-acetylpyridine-(HAPIH), 2-benzoylpyridine- (HBPIH), 2-pyridineformamide- (HPAmIH) and 2-pyrazineformamide-(HPzAmIH) isonicotinoyl hydrazones, as well as the pyrazinamide-derived thiosemicarbazones 2-pyrazineformamide- (HPzAm4DH), N(4)-methyl-2-pyrazineformamide- (HPzAm4M), N(4) -ethyl-2-pyrazineformamide- (HPzAm4E) and N(4)-phenyl-2-pyrazineformamide (HPzAm4Ph) thiosemicarbazones, were assayed for their action against intracellular amastigote form of Leishmania (Viannia) braziliensis strains and the glioblastoma multiforme (SF-295), colon adenocarcinoma (HCT-116), ovarian cancer (OVCAR-8) and acute myeloid leukemia (HL-60) human tumor cell lines. All compounds exhibited leishmanicidal effects, with concentrations at which 50% of parasites were inhibited (IC50) in the 10.70-18.84 mu M range. Moreover, the compounds were up to 30-fold less toxic to macrophages than to the parasites. Pyrazinamide-derived thiosemicarbazones proved to have poor activity against the tumor cell lines at 5 mu g mL(-1), whereas, in general the isoniazid-derived hydrazones presented good activity, being HAPIH and HBPIH the most potent compounds (IC50 = 0.42-1.5 mu M).
