  Structure−Activity Relationships of Substituted 1-Pyridyl-2-phenyl-1,2-ethanediones: Potent, Selective Carboxylesterase Inhibitors

  摘要：

  Inhibition of intestinal carboxylesterases may allow modification of the pharmacokinetics/pharmacodynamic profile of existing drugs by altering half-life or toxicity. Since previously identified diarylethane-1,2-dione inhibitors are decidedly hydrophobic, a modified dione scaffold was designed and elaborated into a > 300 member library, which was subsequently screened to establish the SAR for esterase inhibition. This allowed the identification of single digit nanomolar hiCE inhibitors that showed improvement in selectivity and measured solubility.

  ions led to the assembly of the cage. 1H and DOSY NMR spectroscopy and ESI mass spectrometry data were consistent with the quantitative formation of the cage, and the heterobimetallic structure was confirmed using single‐crystal X‐ray crystallography. The structure of the host–guest adduct with a 2,6‐diaminoanthraquinone guest molecule was determined. Addition of N,N′‐dimethylaminopyridine (DMAP) resulted

  提出了一种策略，可以定量组装异双金属[PdPtL 4 ] 4+笼。两种具有不同灵敏度的不同金属离子（Pd II和Pt II）的存在使笼子经过适当的刺激处理后可以选择性地在一端打开和关闭。惰性Pt II四吡啶基醛络合物与适当取代的吡啶胺和Pd II离子的结合导致了笼的组装。1个H和DOSY NMR光谱和ESI质谱数据与笼的定量形成一致，并且使用单晶X射线晶体学证实了异双金属结构。确定了带有2,6-二氨基蒽醌客体分子的客体-客体加合物的结构。添加N，N'-二甲基氨基吡啶（DMAP）导致形成开架式[PtL 4 ] 2+化合物和[Pd（DMAP）4 ] 2+复合物。然后，在添加对甲苯磺酸（TsOH）的情况下，通过笼子的改造，可以逆转此过程。
