Seven resveratrol-related monomeric stilbenoids were submitted to biomimetic oxidative coupling in the presence of laccase from Trametes versicolor (TvL), and gave racemic dihydrobenzofuran dehydrodimers (±)-15 to (±)-21. These products, after spectral characterization, were submitted to an antiproliferativeactivity bioassay against SW480 human colon cancer cells. Five racemates were found to be active

tools that are both sensitive and selective in detecting spermine. In this study, we presented a "supramolecular cyclization-induced emission enhancement" strategy for the sensitive and selective detection of spermine. A new pillar[5]arene probe (P1) demonstrated excellent solution/solid dual-state emission properties, and the addition of certain spermine (Spm) resulted in fluorescence enhancement due

and product diversity, we herein report the potential of some hybrid molecules with the catechol core to selectively inhibit glioma cells. The intrinsic mode of action of our lead molecule, involving caspase 6 and the quinonemethide pathway, is also reported on the basis of 1H NMR spectroscopy guided metabolomic profiling. We emphatically demonstrate the role of our hybrid molecules, analogues of salvianolic
受天然产物丹酚酸 F 的启发,羟基化苯乙烯基-肉桂酸酯杂化物(C6-C2-C6-C3 单元)的无保护基合成是通过一种步骤经济的途径实现的,该途径包括在一个步骤中形成连续的双 C-C 键锅。该方法通过在一锅中使用简单的前体(即羟基化苯甲醛、芳基乙酸和丙烯酸衍生物)进行多次反应(Perkin 缩合/脱羧-Heck 交叉偶联反应),并以不同产率产生所需的非天然小杂化分子。在微波辐射下 E 选择性为 35-65 %,而报道的合成丹酚酸 F 本身的常规路线需要六个步骤,总产率为 10.0 %,此外还需要对 Wittig 反应产生的 E/Z 异构体进行繁琐的分离. 除了经济的合成和产品多样性之外,我们在此报告了一些具有儿茶酚核心的杂化分子选择性抑制神经胶质瘤细胞的潜力。我们的先导分子的内在作用模式,包括半胱天冬酶 6 和醌甲基化物途径,也在 1H NMR 光谱引导的代谢组学分析的基础上进行了报道。我们着重证明了我们的杂合分子(丹酚酸
