  Synthesis and evaluation of copper complexes of Schiff-base condensates from 5-substituted-2-hydroxybenzaldehyde and 2-substituted-benzenamine as selective inhibitors of protein tyrosine phosphatases

  摘要：

  Five copper complexes, [Cu(bhbb,chbb,ohbb)(H2O)(n)] (tridentate-ligands: H(2)bhbb = 2-(5-bromo-2-hydroxylbenzylideneamino)benzoic acid, 1; H(2)chbb = 2-(5-chloro-2-hydroxylbenzylideneamino)benzoic acid, 2; H(2)nhbb = 2-(5-nitro-2-hydroxyl-benzylideneamino)benzoic acid, 3) and [Cu(cpmp,npmp)(2)] (bidentate-ligands: Hcpmp = 4-chloro-2-((phenylimino)methyl)phenol, 4; Hnpmp = 4-bromo-2-((phenyl-imino)methyl)phenol, 5) have been prepared and characterized by EA, IR, EPR UV-Vis, and ESI-MS. Structure-activity relationship of copper complexes in inhibiting protein tyrosine phosphatases (protein tyrosine phosphatase 1B, PTP1B; T-cell protein tyrosine phosphatase, TCPTP; megakaryocyte protein-tyrosine phosphatase, PTP-MEG2; Src homology phosphatase 1, SHP-1 and Src homology phosphatase 2, SHP-2) is investigated. Inhibitory activities of complexes against the five PTPs indicate that they potently inhibit PTP1B, TCPTP, PTP-MEG2 and SHP-1, but do not inhibit SHP-2. In the complexes, 5 exhibits very strong inhibition (IC50, 0.059 mu M) and better selectivity against PTP1B while 1 and 2 show very strong inhibition (IC50 = 0.089 and 0.067 mu M) and a little selectivity against TCPTP. Compared with the oxovanadium(IV) complexes of same ligands, the copper complexes increase the inhibitory ability against TCPTP, PTP-MEG2 and SHP-1 but decrease the inhibition against SHP-2. For complex 5, the inhibition over PTP1B, TCPTP, PTP-MEG2 and SHP-1 are all improved about 5- to 15-fold compared with the oxovanadium(IV) complex. The results demonstrate that both the ligand structures and the center metals influence the inhibition and selectivity against different PTPs. (C) 2013 Elsevier B.V. All rights reserved.

  dimeric vanadyl(IV) complexes of Schiff bases derived from [1+1] condensation of salicylaldehyde (or its derivatives) and anthranilic acid, have been synthesized from CH3CN and were characterized by elemental analysis, FTIR, EPR, absorption, TGA, cyclic voltammetry and room temperature magnetic susceptibility measurements. These complexes were found to be oxidized by air in polar solvents like MeOH and DMF

  peptides, and metal complexes. Vanadium complexes have been applied for the treatment of diabetes since the 19th century. However, the antidiabetes mechanism remains unclear. In this work, we used four Schiff base oxidovanadium(IV) complexes, namely VO(bhbb)·H2O (1, and ligand 1 H2bhbb, 2-(5-bromo-2-hydroxylbenzylideneamino) benzoic acid), VO(nhbb)·H2O (2, and lignad 2 H2nhbb, 2-(5-nitro-2-hydroxylbenzylideneamino)

  人胰岛淀粉样多肽（hIAPP）的错误折叠和原纤维化与II型糖尿病（T2DM）的病理过程有关。hIAPP聚集的抑制剂包括芳香族有机分子，短肽和金属络合物。自19世纪以来，钒配合物已被用于治疗糖尿病。但是，抗糖尿病机制仍不清楚。在这项工作中，我们使用了四种席夫碱氧化钒（IV）配合物，即VO（bhbb）·H2O（1和配体1 H2bhbb，2-（5-溴-2-羟基苄基亚氨基）苯甲酸），VO（nhbb）· （2和Lignad 2 H2nhbb，2-（5-硝基-2-羟基苄叉亚氨基）苯甲酸），VO（cpmp）2（3和配体3 Hcpmp，4-氯-2-（苯基亚氨基）甲基）苯酚） ，VO（bpmp）2（4和配体4 Hbpmp，4-溴-2-（苯氨基）甲基）苯酚）抑制hIAPP的原纤维形成并减少肽诱导的细胞毒性。结果表明，四种席夫碱氧化钒配合物有效地阻碍了hIAPP的聚集并将成熟的原纤维分解为单体或低聚物。这
