  摘要：

  [(PyNMe3)FeII(CF3SO3)2], 1 与过量的过乙酸在 -40 °C 下反应生成高反应性中间体 2b(PAA)，这是迄今为止非血红素铁氧化环己烷的最快速度物种。它表现出强烈的 490 nm 发色团，与 S = 1/2 EPR 信号相关，g 值为 2.07、2.01 和 1.94。该物种被证明与第二个 S = 1/2 物种 2a(PAA) 处于快速平衡，分配给低自旋酰基过氧化铁 (III) 中心。不幸的是，伴随着 2(PAA) 样品的污染物阻止了穆斯堡尔光谱法对铁氧化态的测定。使用 MeO-PyNMe3（PyNMe3 的富电子版本）和环己基过氧羧酸作为氧化剂得到具有穆斯堡尔异构体位移 δ = -0.08 mm/s 的中间体 3b（CPCA），表明铁（V）氧化态。穆斯堡尔和 EPR 光谱的分析，结合 DFT 研究，表明 3b(CPCA) 的电子基态最好描述为 [(MeO-PyNMe3)FeV(O)(OC(O)R)

Finally, we synthesized a series of analogues in which the ring size of the bis-pyridyl macrocycles was varied between 12 and 16 members per ring including the py[iso-14]aneN(4) ring system, an isomer of the py[14]aneN(4) macrocycle. The p-phenylenebis(methylene)-linked dimer of the py[iso-14]aneN(4) (AMD3329) displayed the highest antiviral activity

  Bis-tetraazAMacrocycles，例如bicyclAM AMD3100，是一类有效的和选择性的抗HIV-1和HIV-2药剂，它们通过结合趋化因子受体CXCR4（X4病毒进入的共同受体）而抑制病毒复制。为了优化双氮杂双环类化合物的抗HIV-1和HIV-2活性，合成了一系列类似物，这些类似物包含中性杂原子（氧，硫）或杂芳香族（pK（a）比仲胺低）替代AMD3100的氨基。将一个或多个杂原子（例如氧或硫）引入对亚苯基双（亚甲基）连接的二聚体的大环中（生成N（3）X或N（2）X（2）双大环），得到类似物大大降低了抗HIV-1（III（B））和抗HIV-2（ROD）的效力。此外，双硫类似物对MT-4细胞也有明显的细胞毒性。然而，具有掺入大环骨架中的单个吡啶基团的双-四氮杂大环化合物显示出与其饱和的脂族对应物相当的抗HIV-1和HIV-2效能。py [14] aneN（4）大环的对亚苯基

By utilization of fragment-based drug discovery (FBDD), a new class of inhibitors for NDM-1 and two related β-lactamases, IMP-1 and VIM-2, was identified. On the basis of 2,6-dipicolinic acid (DPA), several libraries were synthesized for structure–activity relationship (SAR) analysis. Inhibitor 36 (IC50 = 80 nM) was identified

  金属-β-内酰胺酶（MBL）介导的耐药性（特别是新德里金属-β-内酰胺酶-1（NDM-1））的出现和全球传播威胁着β-内酰胺类抗生素的有效性。通过利用基于片段的药物发现（FBDD），鉴定出一类新型的NDM-1抑制剂和两种相关的β-内酰胺酶IMP-1和VIM-2。在2,6-二吡啶甲酸（DPA）的基础上，合成了多个文库用于结构-活性关系（SAR）分析。与其他Zn（II）金属酶相比，抑制剂36（IC 50 = 80 nM）被鉴定为对MBL具有高度选择性。虽然DPA显示出螯合NDM-1中金属离子的倾向，但36形成了稳定的NDM-1：Zn（II）：抑制剂三元络合物，如1所示。1 H NMR，电子顺磁共振（EPR）光谱，平衡透析，固有色氨酸荧光发射和UV-vis光谱。当与36种（对哺乳动物细胞无毒的浓度）共同给药时，亚胺培南对具有NDM-1的大肠杆菌和肺炎克雷伯菌的临床分离株的最低抑制浓度（MIC）降低至易感水平。

  Interlocked supramolecular dendrimers were spontaneously self-assembled from molecular components, metallocycles, and dumbbells bearing benzyl ether repeating units. Here, the metallocycles were in situ self-assembled from L-shaped ligands with dendritic branches, 2,3-dimethyl-2-butene and osmium tetraoxide. The supramolecular dendrimers were stabilized by hydrogen-bonding interactions between the
