    Benzophenone dicarboxylic acid antagonists of leukotriene B4. 2. Structure-activity relationships of the lipophilic side chain
    摘要:
    A series of lipophilic benzophenone dicarboxylic acid derivatives were found to inhibit the binding of the potent chemotaxin leukotriene B4 (LTB4) to its receptor on intact human neutrophils. Activity at the LTB4 receptor was determined by using a [3H]LTB4-binding assay. The structure-activity relationship for the lipophilic side chain was systematically investigated. Compounds with n-alkyl side chains of varying lengths were prepared and tested. Best inhibition of [3H]LTB4 binding was observed with the n-decyl derivative. Analogues with alkyl chains terminated with an aromatic ring showed improved activity. The 6-phenylhexyl side chain was optimal. Substitution on the terminal aromatic ring was also evaluated. Methoxyl, methylsulfinyl, and methyl substituents greatly enhanced the activity of the compound. For a given substituent, the para isomer had the best activity. Thus the nature of the lipophilic side chain can greatly influence the ability of the compounds to inhibit the binding of LTB4 to its receptor on intact human neutrophils. The most active compound from this series, 84 (LY223982), bound to the LTB4 receptor with an affinity approaching that of the agonist.

Markovnikov hydrofunctionalization products are obtained under mild ligand‐free conditions, with up to 99 % yield and >20:1 selectivity.

    A series of trisubstituted benzenes which demonstrate leukotriene B4 (LTB4, 1) receptor affinity was prepared. Previous trisubstituted benzenes from our laboratory showed high affinity to the LTB4 receptor but demonstrated agonist activity in functional assays. Compound 3a, the initial lead compound of this new series, showed only modest affinity (IC50 = 0.20 microM). However, 3a was a receptor antagonist

    An iron/chromium system (Fe(OAc)2, CpCr(CO)3H) catalyzes the preparation of β,γ- or γ,δ-unsaturated amides from 1,4,2-dioxazol-5-ones. An acyl nitrenoid iron complex seems likely to be responsible for C–H activation. A cascade of three H• transfer steps appears to be involved: (i) the abstraction of H• from a remote C–H bond by the nitrenoid N, (ii) the transfer of H• from Cr to N, and (iii) the abstraction

    Unsaturated amides represent common functional groups found in natural products and bioactive molecules and serve as versatile synthetic building blocks. Here, we report an iron(II)/cobalt(II) dual catalytic system for the syntheses of distally unsaturated amide derivatives. The transformation proceeds through an iron nitrenoid-mediated 1,5-hydrogen atom transfer (1,5-HAT) mechanism. Subsequently,
    不饱和酰胺代表天然产物和生物活性分子中常见的官能团,可作为多功能合成构件。在这里,我们报道了一种用于合成远端不饱和酰胺衍生物的铁(II)/钴(II)双催化系统。该转化通过铁氮烯介导的 1,5-氢原子转移 (1,5-HAT) 机制进行。随后,自由基中间体在钴肟催化剂的作用下从邻位亚甲基中夺取氢原子,在温和的条件下有效地生成β,γ-或γ,δ-不饱和酰胺衍生物。共介 HAT 的效率可以通过改变不同的辅助设备来调整,突出了该协议的通用性。值得注意的是,这种去饱和方案还适合实际的可扩展性,能够合成不饱和氨基甲酸酯和脲,它们可以很容易地转化为各种有价值的分子。
