    Synthesis and structure-activity relationships among .alpha.-adrenergic receptor agonists of the phenylethanolamine type
    摘要:
    Nineteen arylethanolamine derivatives related to norepinephrine were prepared and tested for alpha-adrenergic stimulant activity. In one series the analogues possess a p-hydroxy function, while the meta position is substituted by methyl, ethyl, isopropyl, chlohexyl, fluoro, chloro, iodo, carboxy, carbomethoxy, and methylsulfamido groups. The other series is meta hydroxylated with the para position substituted by the same groups. The influence of these groups upon the alpha-adrenergic activity is discussed, and the compounds are compared to octopamine, normetanephrine, norepinephrine, and norphenylephrine. It has been found that the introduction of an isopropyl, cyclohexyl, and fluoro group in the meta position of octopamine improves its affinity by three, five, and six times, respectively, whereas when these groups are introduced in the para position of norphenylephrine their effects are always detrimental. The most active compound, alpha-(aminomethyl)(4-fluoro-3-hydroxyphenyl)methanol (44), has about one-hundredth the affinity and the same intrinsic activity as norepinephrine.

    通过与二烷基磷酸酯的醌甲基甲烷反应提高磷酸三酯形成中的烷基化和产物稳定性
    摘要:
    对功能化对醌甲基化物的反应的研究继续推动了我们为通过磷酸二酯烷基化对DNA进行受控,原位修饰而开发的试剂的设计。先前报道的对儿茶酚衍生的对醌甲基化物的研究可用于捕获可分离的磷酸三烷基酯,以用于表征和机理信息。然而,用这些衍生物形成内酯需要较长的反应时间,导致磷酸三烷基酯和水解产物的不利混合物。为了提高磷酸三烷基酯形成和捕获的速率和功效,苯酚衍生的对-甲基苯醌已被设计为增强构象,该构象有利于磷酸二烷基酯烷基化中间体的内酯化。已通过对-醌甲基化物前体1和相应的对照1 '的UV和1 H NMR分析检查了磷酸二酯烷基化和随后捕获的磷酸三酯加合物的相对速率。甲基的在掺入元的-位1(相对于1 “)显著提高lactionization的速率,以提供高得多的产率得到所需的产品,磷酸三酯内酯5。对照反应与1′仅提供少量的相应的内酯化的磷酸三烷基酯5 ′。
