commercially available, was inactive in the 'tetrad' up to a 20 mg kg(-1) dose (i.v.). Like O-2093, the other four compounds exhibited low affinity in CB(1) (K(i) from 1.3 to >10 microM) and CB(2) binding assays (1.310 microM), very low potency as fatty acidamide hydrolase (FAAH) inhibitors (IC(50)>25 microM) and were inactive in the 'tetrad' up to a 30 mg kg(-1) dose (i.v.). While O-2247 and O-2248 were poor

Bis- and tris-dihydroxyaryl compounds and their methylenedioxy analogs and pharmaceutically acceptable esters, their synthesis, pharmaceutical compositions containing them, and their use in the treatment of amyloid diseases, especially Aß amyloidosis, such as observed in Alzheimer's disease, IAPP amyloidosis, such as observed in type 2 diabetes, and synucleinophathies, such as observed in Parkinson's disease, and the manufacture of medicaments for such treatment.
for templating catenane formation. Accordingly, they were subjected to dynamic covalent chemistry, resulting in a series of [n]rota[n]catenane structures (n = 2, 3, 4). In this process, the N-hetero crown ethers were installed on ammonium template sites of linear and macrocyclic components all at once by a template-directed clipping reaction. The results showed that these novel building blocks could be
由于拓扑结构的要求及其在分子机器和设备中的潜在应用,构造新型的机械互锁结构已成为当前引起人们极大关注的主题。轮烷和连环烷作为两个基本的拓扑构架,可用于构建融合结构。在目前的研究中,合成了一类新型的铵骨架。结合在分子的线性部分中的铵基团可用于模板化轮烷的形成,而分子的大环部分可用于模板化链烷的模板化。因此,它们经受了动态共价化学作用,产生了一系列[ n ] rota [ n ]环烷结构(n= 2,3,4)。在这个过程中,通过模板定向的限幅反应,将N-杂冠醚一次全部安装在线性和大环组分的铵模板位上。结果表明,这些新颖的构建基块可以高效组装。最后,这项研究为将来的研究奠定了基础,该研究旨在构建具有多个拓扑单元的复杂的集成结构或聚合物。

A one‐ and two‐dimensional NMRstudy was performed on three commercial resolphenol—formaldehyde (PF) prepolymerresins. 1H, 13C, CSCM and DQF COSY NMR spectral data, in acetone‐d6, were obtained on each resin and on PF model compounds: phenol, five methylolphenols, four diphenylmethanes, two formals, two dibenzyl ethers and two dibenzylamines. Gated‐decoupled 13C experiments, using 2,4,6‐trimethylphenol
