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。
Synthesis, thermal, electrochemical and catalytic behavior toward transfer hydrogenation investigations of the half-sandwich RuII complexes with 2-(2′-quinolyl)benzimidazoles
Abstract A series ligands (L3-14) of derived from 2-(2′-quinolyl)benzimidazole (QuBim, L1) and 2-(2′-quinolyl)-5,6-dimethylbenzimidazole (QuDmBim, L2) which are an NN-type ligands have been synthesized and characterized with various techniques such as NMR, UV–vis, FT-IR spectroscopy, elemental analysis and X-ray diffraction. The substituted ligands derived from QuBim and QuDmBim have been used as sustaining
