• Thermal and mechanical properties of azomethine functionalized cyanate ester/epoxy blends

  azomethine functionalized diols were synthesized by the condensation reaction of aromatic diamines with 4-hydroxy benzaldehyde. Aromatic diamines with different alkyl chain lengths have been used to prepare the bisphenols. These bisphenols were converted to their corresponding cyanate esters by treating with cyanogen bromide (CNBr) in the presence of triethyl amine (Et3N). The curing temperature was measured

  通过芳族二胺与4-羟基苯甲醛的缩合反应合成了一系列偶氮甲碱官能化的二醇。具有不同烷基链长的芳族二胺已用于制备双酚。通过在三乙胺（Et 3 N）存在下用溴化氰（CNBr）处理，将这些双酚转化为相应的氰酸酯。使用差示扫描量热法（DSC）测量固化温度。这些氰酸酯的最高固化温度为203–242°C。使用热重分析（TGA）研究了固化的氰酸酯的热性能。聚合物显示出优异的热稳定性（T 5％在358至465°C的范围内，T发现10％在508至525°C的范围内，而在800°C下的焦炭收率百分比在37.06至57.26的范围内。使用极限氧指数值（在800°C下在32.32至40.40的范围内）评估氰酸酯树脂的阻燃性。制备了氰酸酯/环氧树脂混合物，并通过扫描电子显微镜研究了混合物的形态。使用动态力学分析（DMA）研究了氰酸酯/环氧酯共混物的机械性能和玻璃化转变温度，发现T g随着氰酸酯含量的增加（1-5％）而增加。

  pillar[5]arenes with 1,ω-bis(4-isothiocyanatophenoxy)alkanes also afforded diphenoxyalkylene thiourea-bridged dipillar[5]arenes. 1H NMR and NOESY spectra clearly indicated that bis-[1]rotaxanes were formed by insertion of longer alkylene chains into the cavities of two pillar[5]arenes. On the other hand, the free-forms of dipillar[5]arenes were obtained with the shorter ethylene chains existing on the outside

• Biological properties of amidinium sulfinic and sulfonic acid derivatives: inhibition of glycolytic enzymes of Trypanosoma brucei and protective effect on cell growth

  The activity of the title compounds has been investigated on two biological targets: cultures of trypanosome and glycolytic enzymes inhibition of the parasite, and on retinal epithelium cells. In both cases, these compounds exhibit a significant activity, in some cases more selective than this for the drug suramin, with a lower toxicity. The effect of these compounds, which exist as neutral and zwitterionic forms in the case of sulfinic, only as zwitterionic in the case of sulfonic derivatives can be understood via their action on clusters of positive charges which are present at the surface of the proteins involved in the processes: glycolytic enzymes of the trypanosome in the first part, basic fibroblast growth factor in the second.
