number of MPTP and MPP(+) derivatives that are suitable for the comparative neurotoxicity and complexIinhibition versus dopamine metabolism perturbation studies. Structure-activity studies with bovine chromaffin granule ghosts show that 3'-hydroxy-MPP(+) is one of the best known substrates for the vesicular monoamine transporter (VMAT). A series of compounds that combine the structural features of
Encapsulation Enhanced Dimerization of a Series of 4-Aryl-<i>N</i>-Methylpyridinium Derivatives in Water: New Building Blocks for Self-Assembly in Aqueous Media
The construction of supramolecular systems in aqueousmedia is still a great challenge owing to the limited sources of buildingblocks. In this study, a series of 4‐aryl‐N‐methylpyridinium derivatives have been synthesized. They formed very stable host–guest (1:2) complexes with CB[8] in water (binding constants up to 1014 M−2) with the two guest molecules arranged in a head‐to‐tail manner and the
由于结构单元的来源有限,在水性介质中构建超分子系统仍然是一个巨大的挑战。在这项研究中,已经合成了一系列的4-芳基-N-甲基吡啶鎓衍生物。他们与水中的CB [8]形成了非常稳定的宿主-客体(1:2)配合物(结合常数高达10 14 M -2),两个客体分子以头尾相接的方式排列,并且配合物表现出很高的通过1 H NMR和UV / Vis光谱研究,ITC和晶体学分析揭示了其热稳定性。

A direct pyridinium C–H sulfonylimination has been developed for the synthesis of sulfonyl iminopyridine derivatives with high efficiency. This transformation features the direct and efficient formation of a C═N bond with a high functional group tolerance under metal-free conditions. The spectroscopic properties potentially enable these sulfonyl iminopyridine compounds to be useful new emitting materials
