while the nonoxido VIV-compounds 2 and 3 are partly converted into their corresponding VIVO complexes, [VIVO(L2–3)(H2O)] (2′ and 3′). Interaction of these VVO2, VIVO, and VIV systems with two model proteins, ubiquitin (Ub) and lysozyme (Lyz), is investigated through docking approaches, which suggest the potential binding sites: the interaction is covalent for species 2′ and 3′, with the binding to Glu16
一种氧化乙氧基氧化钒(V)[V V O(L 1)(OEt)](1)和两种非氧化钒(IV)配合物[V IV(L 2–3)2 ](2和3)的合成和表征,据报道,其具有掺有萘基的芳酰hydr配体。通过各种物理化学技术对合成的氧化钒和非氧化钒配合物进行表征,并通过单晶X射线衍射(SC-XRD)解析其分子结构。这表明,在1中,钒原子周围的几何形状对应于扭曲的方锥,其O 4N配位球,而两个非氧化V IV配合物2和3的配位球则对应于每个“裸”钒中心周围O 4 N 2配位球的扭曲三角棱柱形排列。在水溶液中,在V V的O部分1只经历一个变化到V V Ò 2种,得到[V V ø 2(L 1)] - (1' ),而nonoxido V IV -化合物2和3被部分转化为它们相应的V IV O络合物[V IV O(L 2–3)(H 2 O)](2'和3')。通过对接方法研究了这些V V O 2,V IV O和V I
