  Leukotriene B4 (LTB4) Receptor Antagonists: A Series of (Hydroxyphenyl)pyrazoles

  摘要：

  A series of (hydroxyphenyl)pyrazoles was designed by molecular modeling comparison with the LTB(4) structure and prepared for evaluation as LTB(4) receptor antagonists, culminating in 4-ethyl-5-[[6-methyl-6-(1H-tetrazol-5-yl)heptyl]oxy]-2-(1H-pyrazol-3-yl)phenyl (2). Using an assay for inhibition of specific [H-3]LTB(4) binding to human PMN, it was found that the pyrazole ring could be methylated at N(1) with little loss of activity while methylation at N(2) reduced activity significantly. The structure-activity relationship of the terminal acid group was investigated. Good activity was found with o- and m-phenylalkanoic acids, chromane carboxylic acid, and tetrazole groups. The best in vitro activity was realized with the pyrazole nitrogen unsubstituted and with a six-carbon chain linking the phenyl ether oxygen to the tetrazole group. Compound 2, having an IC50 of 6.4 +/- 0.8 nM in the binding assay, was selected for further preclinical evaluation.

  A series of 3‐dodecanoylindole‐2‐carboxylic acid derivatives with varied carboxylic acid substituents at the indole 1‐position were synthesized and evaluated for their ability to inhibit arachidonic acid release in human platelets mediated by the cytosolic phospholipase A2. Structure‐activity relationship studies revealed that increasing the polarity of these substituents by the introduction of additional

  reactivity and selectivity control of unactivated alkyl halides. Here we report a general strategy for electrochemical cross-electrophile coupling of unactivated alkyl halides under nickel catalysis. The highly selective electrochemical cross-electrophile coupling process was carried out in an operationally simple manner with high selectivity, setting the stage for the challenging C(sp3)–C(sp3) bonds

  C( sp 3 )–C( sp 3 ) 连接在天然产物、药物和有机化合物中无疑是重要的。电化学交叉亲电子试剂与多种可用的卤代烷偶联是构建 C( sp 3 )–C( sp 3 ) 键的一种有吸引力且有用的策略，尽管在之前的报道中只能在活化的卤代烷上看到成功，由于未活化的烷基卤化物的反应性和选择性控制面临巨大挑战。在这里，我们报告了在镍催化下未活化的烷基卤化物电化学交叉亲电子偶联的一般策略。高选择性电化学交叉亲电子偶联过程以操作简单的方式进行，具有高选择性，为具有挑战性的C( sp 3 )–C( sp 3 )键结构与多功能未活化的烷基卤化物奠定了基础，包括交叉-伯-伯卤化物、伯-仲卤化物、伯-叔卤化物和仲-仲卤化物的偶联，具有高选择性和优异的官能团相容性。多样化的产品以及生物相关化合物的各种后期修饰，证明了其在有机合成和药物化学中的潜在用途。

  The first copper-catalyzed/promoted sp(3)-C SuzukiMiyaura coupling reaction of gem-diborylalkanes with nonactivated electrophilic reagents is reported. Not only 1, 1-diborylalkanes but also some other gem-diborylalkanes can be coupled with nonactivated primary alkyl halides, offering a new method for sp(3)Csp(3)C bond formation and, simultaneously, providing a new strategy for the synthesis of alkylboronic esters.
