  A series of six homoleptic bis-cyclometalated ruthenium complexes, Ru(N^N^C)2, is reported where N^N^C is a 6-(2,4-difluoro-3-R3-phenyl)-4-R2-4′-R1-2,2′-bipyridine with R3 = −H or −CF3 and R2 and R1 = −COOEt or −CF3. An effective synthesis of the ligands and the complexes is described. The UV–visible absorption studies demonstrate that these complexes are panchromatic dyes absorbing up to 900 nm. Importantly

  报道了一系列六个均一的双环金属化钌络合物Ru（N ^ N ^ C）2，其中N ^ N ^ C是6-（2,4-二氟-3-R 3-苯基）-4- R 2 -4'-R 1 -2,2'-联吡啶，其中R 3 = -H或-CF 3且R 2和R 1 = -COOEt或-CF 3。描述了配体和配合物的有效合成。紫外可见吸收研究表明，这些络合物是吸收高达900 nm的全色染料。重要的是，吸收的开始仅取决于金属化苯基上的取代，而整个光谱的吸收强度是苯基和联吡啶部分上的取代基的函数。在电化学中观察到相同的趋势，因为氧化还原间隙仅取决于金属化苯基上的取代，而氧化和还原电势是苯基和联吡啶部分上的取代基的函数。用作染料敏化太阳能电池敏化剂的初步测试表明，染料上的锚定基团数量对器件效率有重要影响。

  non-alcoholic fatty liver disease (NAFLD) generalized in the term metabolic syndrome. Adipose triglyceride lipase (ATGL) is the initial enzyme in the hydrolysis of intracellular triacylglycerol (TG) stores, liberating fatty acids that are released from adipocytes into the circulation. Hence, ATGL-specific inhibitors have the potential to lower circulating FA concentrations, and counteract the development of insulin

  高血清脂肪酸（FA）水平与胰岛素抵抗的发展存在因果关系，胰岛素抵抗最终发展为2型糖尿病和在代谢综合征中普遍存在的非酒精性脂肪肝疾病（NAFLD）。甘油三酸酯脂肪酶（ATGL）是细胞内三酰基甘油（TG）储存液水解的初始酶，可释放从脂肪细胞释放到循环中的脂肪酸。因此，ATGL特异性抑制剂具有降低循环FA浓度并抵消胰岛素抵抗和NAFLD发生的潜力。在本文中，我们报告了鼠ATGL的小分子抑制剂的结构-活性关系（SAR）研究，该研究导致Atglistatin的发展。Atglistatin是鼠ATGL的特异性抑制剂，

  The palladium-catalyzed directed C–H halogenation of bipyridine N-oxides was investigated. Using NCS or NBS (N-chloro- or N-bromosuccinimide) and 5 mol % Pd(OAc)2 in chlorobenzene (0.10 molar) at 110 °C, pyridine-directed functionalization took place and 3-chloro- or 3-bromobipyridine N-oxides were obtained in high yields. The reaction is sensitive to steric hindrance by 4- and 6′-substituents. Only
