properties with metal ions other than Zn(II) have not been reported, which might reveal similarities and differences between MBIs and the parent MBPs. To this end, [M(TPA)(MBI)]+ (M = Ni(II) and Co(II), TPA = tris(2-pyridylmethyl)amine) is presented as a bioinorganic model system for investigating picolinic acid, four heterocyclic MBIs, and 2,2′-bipyridine. These complexes were characterized by X-ray crystallography
生物电子等排物是解决药代动力学缺陷和改善类药特性的有用方法。针对开发金属酶抑制剂,金属结合药效团 (MBP) 已与生物电子等排体结合,以产生金属结合等排体 (MBI) 作为用于基于片段的药物发现 (FBDD) 的替代支架。吡啶甲酸 MBI 的金属结合能力、药代动力学特性和酶抑制活性已被报道和评估。然而,它们与 Zn(II) 以外的金属离子的结构、电子和光谱性质尚未见报道,这可能揭示了 MBI 与母体 MBP 之间的异同。为此,[M(TPA)(MBI)] +(M = Ni(II) 和 Co(II),TPA = 三(2-吡啶基甲基)胺)作为生物无机模型系统用于研究吡啶甲酸、四个杂环 MBI 和 2,2'-联吡啶。这些配合物通过 X 射线晶体学以及核磁共振、红外和紫外-可见光谱进行表征,并获取了它们的磁矩。此外,[(Tp Ph,Me )Co(MBI)] (Tp Ph,Me = hydrotris(3
