Vascular endothelial growth factor receptor-2 (VEGFR-2) plays a crucial role in tumor angiogenesis, and inhibition of the VEGFR-2 signaling pathway has emerged as an attractive target for cancer therapy. In our effort, a novel series of picolinamide-based derivatives were designed and synthesized as potent and effective VEGFR-2inhibitors. All the newly prepared compounds were evaluated in vitro for
waxy or even insoluble stilbazoles. Moreover, the oxalicacid loading could be lowered to sub-stoichiometric amounts. When further optimizations were needed, our strategy was found to be highly flexible to identify other oligocarboxylic acids as alternative additive to improve or even overturn regioselectivity. Oxalicacid and other oligocarboxylic acids were found to be capable of orienting more than

The fabrication of a cationic nanoporous smecticliquidcrystal network (LCN) based on hydrogen bonded heterodimers is presented. The method relies on a supramolecular complex made from a pyridyl bearing reactive mesogen hydrogen bonded to a non-reactive benzoic acid template. Upon addition of a cross-linker, a smecticliquid crystalline phase is obtained that can be fixed by photopolymerization. It
介绍了一种基于氢键异二聚体的阳离子纳米多孔近晶液晶网络(LCN)的制备。该方法依赖于由带吡啶基的反应性液晶元氢与非反应性苯甲酸模板键合而成的超分子复合物。添加交联剂后,获得可以通过光聚合固定的近晶液晶相。发现当使用25wt%或更多的交联剂时,在除去模板后层状结构得以保持,从而产生纳米孔LCN。在将H 3 PO 4固定在LCN的孔中之后,获得了阳离子2D纳米多孔聚合物,该聚合物显示出高且各向异性的无水质子电导率。
Silicas with Covalently Anchored Fluorosolvatochromic Dyes Suitable for Naked-Eye Detection of Colourless Compounds
In this work, two stilbenederivatives with different substituents on the phenolic core (phenyl and dimethoxyphenyl) were prepared. The fluorosolvatochromic response of their N-propylated derivatives was studied in a solution of twelve different solvents using UV–Vis absorption and fluorescence emission spectra. Both stilbazolium dyes showed a significant negative solvatochromic effect, with a hypsochromic

of the VEGFR-2 signaling pathway has already become an attractive approach for cancer therapy. In this study, a novel pyrimidine-based derivative 7j was designed as lead compound, and three series of potent VEGFR-2 inhibitors were synthesized and biologicallyevaluated against A549 and HepG2 cell lines. Compounds 7d, 9s and 13n exhibited superior inhibitory activities against A549 cell with IC50 ranged
