  基于修饰的人血清白蛋白IB亚域中的His146残基开发抗癌铜（II）多靶标前药

  摘要：

  设计具有改善的体内递送和治疗效率的多靶点抗癌药物提出了巨大的挑战。因此，我们建议基于棕榈酸（PA）修饰的人血清白蛋白（HSA-PA）IB亚域中的His146残基，设计一种衍生自硫半脲的抗癌多靶标金属前药。研究了六种Cu（II）化合物与6-甲基-2-甲酰基吡啶-4 N-取代的硫代半氨基甲酮的结构-活性关系，然后证实了4b在癌细胞DNA和蛋白质中的多靶标能力。HSA–PA– 4b复合物（HSA–PA– 4b）的结构揭示了4b结合到修饰的HSA的IB子结构域，并且His146取代4b中的硝酸盐配体，与Cu 2+配位，而PA通过与Lys199和His242形成氢键的羧基与IIA子结构域复合。体内数据显示4b和HSA–PA– 4b复合物抑制肺肿瘤的生长，并且PA修饰的HSA复合物的靶向能力和治疗功效强于单独的4b。

  07 ± 0.043 µM, 2.18 ± 0.058 µM both possessed significant activity. Furthermore, molecular docking and kinetic studies were performed for the most potent inhibitors to demonstrate the binding mode of the active pyridine carbothioamide with the enzyme urease and its mode of interaction. The ADME profile also showed that all the synthesized molecules present oral bioavailability and high GI absorption

  与各种危及生命的病症例如胃癌和十二指肠癌相关的尿素分解细菌的耐药性的快速发展导致需要开发具有抗脲酶活性的新疗法。通过缩合反应合成了一系列具有新颖结构的吡啶甲酰胺和硫代甲酰胺衍生物，并研究了它们对脲酶的抑制作用。该系列中，5-氯吡啶-2基亚甲基肼硫甲酰胺(Rx-6)和吡啶2-基亚甲基肼甲酰胺(Rx-7) IC50 = 1.07 ± 0.043 µM、2.18 ± 0.058 µM均具有显着的活性。此外，对最有效的抑制剂进行了分子对接和动力学研究，以证明活性吡啶硫代甲酰胺与脲酶的结合模式及其相互作用模式。 ADME 曲线还表明，所有合成的分子均具有口服生物利用度和高胃肠道吸收。

  Magnetic and spectral data support a square-planar structure for [Cu(NNS)X] (X = Cl, Br, NO 3 , CH 3 COO) and a distorted octahedral structure for [Cu(NNS) 2 ] · 0.5H 2 O. The crystal and molecular structure of [Cu(NSS)Cl] has been determined by X-ray diffraction. This complex has a distorted square-planar geometry with the copper(II) ion lying in an approximate plane of four coordinating atoms, three of which

  Copper(II) complexes of general formula, [Cu(NNS)(H2O)(x)X]. nH(2)O (NNS- = uninegatively charged tridentate thiosemicarbazone ligand formed from 6-methyl-2-formylpyridine; X = NCS-, CH3COO-, N-3(-); x = 0,1; n = 0.5, 1) and [Cu(HNNS)(H2O)(SO4)]. H2O have been synthesized and characterized by a variety of physico-chemical techniques. Magnetic and spectroscopic evidence support a square-planar structure for the [Cu(NNS)X] (X = NCS-, N-3(-)) complexes and a five-coordinate structure for the [Cu(HNNS)(H2O)(SO4)]. H2O complex. The crystal structures of the [Cu(NNS)(CH3COO)(H2O)] and [Cu(HNNS)(H2O)(SO4)]. H2O complexes have been determined by X-ray diffraction. The acetato complex has a distorted square-pyramidal geometry with the thiosemicarbazone ligand acting as a uninegatively charged tridentate NNS chelating agent and the fourth and fifth coordination positions of the copper(II) ion are occupied by a unidentate acetate and water ligand, respectively. The sulphate-complex is also five-coordinate with the thiosemicarbazone coordinated as a neutral NNS ligand and the fourth and fifth coordination sites are occupied by a water molecule and a unidentate sulphate ligand, respectively.
