Several new Ru(II) polypyridyl complexes of the novel tetradentate thioether 1,2-bis[3′-(2″-pyridyl)-1′-thiapropyl]benzene (Ppes) form from the dinuclear ruthenium(II) complex [Ru(Ppes)}2(µ-Cl)2]2+ via reaction with various bidentate diimines. Facile symmetrical bridge cleavage occurs, producing mononuclear complexes of the form [Ru(Ppes)(L)]2+, where L is the bidentate diimine. Redox chemistry shows single-electron

novel antagonists of adenosinereceptors (ARs) by competition experiments using humanA1, A2A, and A3 ARs. The new compounds were designed based on derivatives of 2‐(benzimidazol‐2‐yl)quinoxaline, previously reported as potent and selectiveantagonists of A1 and A3 ARs. Among these, 3‐[4‐(ethylthio)‐1H‐benzimidazol‐2‐yl]isoquinoline 4 b exhibited the best combination of potency toward the A1 AR (Ki=1
通过使用人A 1,A 2A和A 3 AR进行竞争实验,合成了许多以各种方式连接到取代的苯并咪唑-2-基系统的喹啉和异喹啉,并将其评价为新型腺苷受体(ARs)拮抗剂。新化合物是基于2-(苯并咪唑-2-基)喹喔啉的衍生物设计的,该衍生物以前被报道为A 1和A 3 AR的有效和选择性拮抗剂。其中,3- [4-(乙硫基)-1 H-苯并咪唑-2-基]异喹啉4b表现出对A 1 AR(K i = 1.4 n M)和对A 2A(K i > 10μm), A 2B(K i > 10μm)和A 3 ARs(K i > 1μM)的选择性。在分离的人结肠的圆形平滑肌制剂中的功能实验表明,4b在该肠区域的神经肌肉区室中充当A 1 AR的有效和选择性拮抗剂。生物学和药理学数据表明4b是开发具有结肠活动刺激特性的新型药物的合适起点。
2-Benzoimidazol-8-alkylquinolinylnickel(II) complexes as efficient catalysts for ethylene oligomerization and vinyl polymerization of norbornene
its derivatives, were prepared as potential catalysts for the oligomerization of ethylene. The molecular structure of a representative complex C2·CH3CH2OH was determined by single-crystal X-ray diffraction. Upon treatment with diethylaluminium chloride (Et2AlCl), all nickel complex pre-catalysts exhibited good activities in the oligomerization of ethylene. Furthermore, in the presence of methylaluminoxane
制备了一系列镍配合物 LNiCl2 (C1-C16),其中 L 代表 2-苯并咪唑-8-烷基喹啉及其衍生物,作为乙烯低聚反应的潜在催化剂。代表性配合物 C2·CH3CH2OH 的分子结构由单晶 X 射线衍射确定。用二乙基氯化铝 (Et2AlCl) 处理后,所有镍配合物预催化剂在乙烯低聚反应中都表现出良好的活性。此外,在甲基铝氧烷 (MAO) 存在下,镍预催化剂适用于降冰片烯的乙烯基聚合。图形概要
