A novel class of nonamphiphilic aromatic amides (T1–T3) have been designed and synthesized from naphthalene-2,7-diamine or 2-amino-naphthalene and a 5-hydroxy-isophthalic acid segment, which is revealed to selectively assemble into vesicular or tubular architectures, depending on the solvents and concentrations. T1 and T2 form vesicles in methanol, but can be converted into micro/nano-tubes when water

In this contribution, we describe the preparation and recognition characteristics of a novel tetrapodal benzene cage (). The cage can express a wide recognition range without losing selectivity for the object of appropriate size and functional groups. The key to obtaining the desired structural isomer of is the synthesis and isolation of the -bis(bromomethyl)benzene precursor (). Three distinct guests
在这篇文章中,我们描述了一种新型四足苯笼的制备和识别特性()。笼子可以表达较宽的识别范围,同时又不失去对适当大小和功能组的物体的选择性。获得所需结构异构体的关键是-双(溴甲基)苯前体()的合成和分离。选择三种不同的客体:F(极小尺寸)、-lactate(适当尺寸)和-Asp(支链形状)作为例子来展示 的识别特征。通过NMR滴定研究,它们在竞争性介质(10%DMSO/THF)中均表现出良好的结合亲和力(>10L/mol),表明具有广泛的识别范围。观察到 β 乳酸的结合常数最高,表明对 β 乳酸 F 和 -Asp 具有良好的选择性。此外,F在DMSO中的NMR滴定研究表明,对于小尺寸客体可以实现不同的结合模式(1:1和2:1客体-主体),这使得二元结合特性的进一步发展以及随后在该领域的应用成为可能。的催化作用。

Two new hydrazide-based quadruple hydrogen-bonding motifs are described. Dipodals based on these two motifs are revealed to form supramolecular polymers, which can further aggregate to form vesicles and/or organogels in hydrocarbons. The quadruple hydrogen-bonding motifs are characterized by the Xray diffraction and (2D) H-1 NMR experiments, while the vesicles and organogels are evidenced by SEM, AFM TEM, and fluorescent microscopy.

The present invention provides an amide derivative having a stilbene or 1,2-diphenylethane moiety within the molecule thereof, a process for the preparation thereof, and a pharmaceutical composition comprising the same. The amide derivative of the present invention activates glucokinase remarkably, and therefore they can be usefully applied for treating glucokinase-mediated diseases, such as hyperglycemia and diabetes.
