在这里,我们报告了两个具有非常规形状的新系列介晶同系物的设计和合成。3-(( 4- n-烷氧基苯甲酰基)氧基)-4-((4-硝基苯基)二氮烯基)苯基4-氯苯甲酸酯( I n, n = 1 to 8, 10, 12, 14 &16)和3-(( 4 - n-烷氧基苯甲酰基)氧基)-4-((4-硝基苯基)二氮烯基)苯基4-硝基苯甲酸酯( II n, n = 通过元素分析和标准光谱方法合成了 1 至 8、10、12、14 和 16) 衍生物并对其进行了表征。这些衍生物在中心含有偶氮基团以及末端酯键和侧链烷氧基链。以4-(对硝基苯偶氮)间苯二酚染料为原料,制备了对位含有氯和硝基的两种不同同源偶氮二酯系列。通过与 4-氯苯甲酸反应,在染料的酚基 -OH 基团上进行酯化,得到系列 - I n的不同衍生物和系列 - II n的 4-硝基苯甲酸. DFT 研究揭示了从甲氧基到十六烷氧基衍生物的常规形状的结
A novel, single-chained ammonium amphiphile that carries an o-hydroxyazobenzene unit at the terminus of its hydrophobic chain has been synthesized. This compound forms ordered thread-like aggregates upon dispersion in water. These aggregates exhibit a phase transition at 56 °C. The o-hydroxyazobenzene unit binds several transition-metal ions in a 2:1 stoichiometry. Binding of these metal ions results
intraannular position have been synthesized by copper(I) catalyzed 1,3 dipolar cycloaddition of the corresponding propargylic esters with various phenyl substituted aliphatic azides under mild conditions through click methodology. The 1 : 1 oligomeric triazolophanes exhibit good target binding ability and better antibacterial activity againstStaphylococcusaureus, Bacillus subtilis, Salmonella typhi and Escherichia

The present invention relates to compounds suitable as modulators of protein misfolding and/or protein aggregation. The compounds are particularly suitable as inhibitors of amyloid aggregate formation and/or modulators of amyloid surface properties, and/or as activators of degradation or reduction of amyloid aggregates.
Abstract In the present study, a series of azoderivatives (TR-1 to TR-9) have been synthesised via the diazo-coupling approach between substituted aromatic amines with phenol or naphthol derivatives. The compounds were evaluated for their therapeutic applications against alpha-glucosidase (anti-diabetic) and pathogenic bacterial strains E. coli (gram-negative), S. aureus (gram-positive), S. aureus

The first examples of photo-responsive azobenzene-containing oxacalixarenes have been synthesized via a 3+1 macrocyclization approach. Introduction of the photoresponsive unit was achieved by using 4-phenylazoresorcinol or (E)-4-(4′-nitrophenylazo)resorcinol as the nucleophilic component in the macrocyclization reaction. These novel macrocycles have been characterized by means of 1D and 2D NMR spectroscopy
