Intramolecularhydrogenbond (IMHB) interactions have attracted considerable attention due to their central role in molecular structure, chemical reactivity, and interactions of biologically active molecules. Precise correlations of the strength of IMHB's with experimental parameters are a key goal in order to model compounds for drug discovery. In this work, we carry out an experimental (NMR) and

TRAP-6/IC50 Collagen) and the inhibitory capacity of platelet aggregation. Compounds 3 and 8 inhibit agonist-induced platelet aggregation in a non-competitive manner with IC50 values of 1.77 ± 2.09 μM (collagen) and 11.88 ± 4.59 μM (TRAP-6), respectively and show no cytotoxicity. Both compounds do not affect intracellular calcium levels and mitochondrial bioenergetics. Consistently, they reduce the expression
心血管疾病是世界上主要的死亡原因。血小板在心血管事件中起主要作用,因为它们与受损的内皮细胞结合并形成血栓。尽管某些含氢醌支架的化合物具有已知的抗血小板活性,但目前尚缺乏有关带有电子吸引子基团的氢醌的抗血小板活性的证据。在这项工作中,我们使用胶原蛋白和凝血酶受体激活肽6(TRAP-6)作为激动剂,评估了一系列邻羰基氢醌衍生物对人血小板的细胞毒性和功能的抗血小板作用。我们的结构-活性关系研究表明,宝石的-二乙基/甲基取代和C3的第三个环的添加/修饰邻羰基氢醌支架对选择性指数(IC 50 TRAP-6 / IC 50胶原蛋白)和血小板聚集抑制能力的影响。化合物3和8以非竞争性方式通过IC 50抑制激动剂诱导的血小板凝集胶原蛋白值分别为1.77±2.09μM和11.88±4.59μM(TRAP-6),且无细胞毒性。两种化合物均不影响细胞内钙水平和线粒体生物能。一致地,它们降低了P-选择蛋白的表达,糖蛋白IIb

selective oxidative cleavage reaction which produces ketones and formamides. The ketones can be isolated in high yield and purity by a simple workup procedure. The oxidizing agent is selective and preferentially oxidizes an enamine carbon-carbon double bond in the presence of a distal carbon-carbon double bond. Other functional groups unaffected by this reagent include nitriles, secondary alcohols, and

supported on zeolite can be used for the selective oxidation of various enamines, alkylarenes and unsaturatedalcohols to the corresponding ketones, in good yield. Arenes were selectively oxidized at the benzylic position. If the benzylic carbon is secondary, ketones are obtained, and alcohols are produced if the benzylic position is tertiary. In contrast unsaturated secondary alcohols selectively undergo
