  Imidazopyridazines as potent inhibitors of Plasmodium falciparum calcium-dependent protein kinase 1 (PfCDPK1): Preparation and evaluation of pyrazole linked analogues

  摘要：

  The structural diversity and SAR in a series of imidazopyridazine inhibitors of Plasmodium falciparum calcium dependent protein kinase 1 (PfCDPK1) has been explored and extended. The opportunity to further improve key ADME parameters by means of lowering log D was identified, and this was achieved by replacement of a six-membered (hetero)aromatic linker with a pyrazole. A short SAR study has delivered key examples with useful in vitro activity and ADME profiles, good selectivity against a human kinase panel and improved levels of lipophilic ligand efficiency. These new analogues thus provide a credible additional route to further development of the series. (C) 2013 The Authors. Published by Elsevier Ltd. All rights reserved.

  A comparative study on Co-III-catalyzed direct C-H bond alkenylation of 1-phenylpyrazole derivatives with alkynyl carboxylic acids and arylalkynylsilanes under redox-neutral conditions has been disclosed. These methods show excellent selectivity with good to excellent yields. Trimethylsilylacetylene has been utilized as a vinyl source to obtain the corresponding styrene derivatives. The major differences

  Ambient temperature ruthenium‐catalyzed C−H arylations were accomplished by visible light without additional photocatalysts. The robustness of the ruthenium‐catalyzed C−H functionalization protocol was reflected by a broad range of sensitive functional groups and synthetically useful pyrazoles, triazoles and sensitive nucleosides and nucleotides, as well as multifold C−H functionalizations.

  which the C(sp2)-18F bond is formed via a copper-mediated pathway. Copper N-heterocyclic carbene complexes serve as mediators for this transformation, using aryl halide substrates with directing groups at the ortho position. This reaction is applied to the radiofluorination of electronically diverse aryl halide derivatives, including the bioactive molecules vismodegib and PH-089.

  [18F] 标记的芳基氟化物被广泛用作正电子发射断层扫描 (PET) 成像的放射性示踪剂。芳基卤化物 (ArX) 是这些放射性示踪剂特别有吸引力的前体，因为它们易于获得、价格低廉且稳定。然而，迄今为止，从芳基卤化物直接制备 [18F]-芳基氟化物仍然仅限于高度活化的 ArX 底物和 K18F 之间的 SNAr 反应。本报告描述了一种芳基卤化物放射性氟化反应，其中 C(sp2)-18F 键是通过铜介导的途径形成的。铜 N-杂环卡宾配合物用作这种转化的介体，使用在邻位具有导向基团的芳基卤化物底物。该反应适用于电子不同的芳基卤化物衍生物的放射性氟化，
