  • Antioxidant Activities of Vitamin E Analogues in Water and a Kamlet−Taft β-Value for Water<sup>1</sup>
    作者:Luca Valgimigli、K. U. Ingold、J. Lusztyk
    DOI:10.1021/ja954030r
    日期:1996.1.1
    (α-TOH, vitamin E) analogues by tert-butoxyl radicals have been measured at room temperature in four solvents, including water. The results imply that H-atom abstraction from α-TOH is 3.9 times slower in water than in benzene and yield a “reliable” Kamlet−Taft β solvent parameter for water of 0.31. Literature rate constants for H-atom abstraction by peroxyl radicals from α-TOH in SDS micelles and in
    在室温下,在四种溶剂(包括水)中测量了通过叔丁氧基自由基从两种水溶性 α-生育酚(α-TOH,维生素 E)类似物提取氢原子的速率常数。结果表明,从 α-TOH 中提取 H 原子在水中比在苯中慢 3.9 倍,并且对水产生“可靠”的 Kamlet-Taft β 溶剂参数为 0.31。在 SDS 胶束和磷脂胶束中,过氧自由基从 α-TOH 中提取 H 原子的文献速率常数分别比在苯乙烯中低约 100 倍和 1000 倍。由于观察到的速率降低中只有一小部分可归因于 α-TOH 与水的氢键结合,因此可以得出结论,在这些异质系统中,大部分 α-TOH 物理上无法被攻击自由基接触。

    The subject invention provides pharmaceutical compounds useful in the treatment of Type II diabetes. These compounds are advantageous because they are readily metabolized by the metabolic drug detoxification systems. Particularly, thiazolidinedione analogs that have been designed to include esters within the structure of the compounds are provided. This invention is also drawn to methods of treating disorders, such as diabetes, comprising the administration of therapeutically effective compositions comprising compounds that have been designed to be metabolized by serum or intracellular hydrolases and esterases. Pharmaceutical compositions of the ester-containing thiazolidinedione analogs are also taught.
    该发明提供了在治疗2型糖尿病中有用的药物化合物。这些化合物具有优势,因为它们可以被代谢药物解毒系统迅速代谢。特别地,设计了包含酯基的噻唑烷二酮类似物的化合物。该发明还涉及治疗疾病的方法,如糖尿病,包括给予经设计为能够被血清或细胞内酯酶代谢的化合物的治疗有效组合物。还教授了含酯基的噻唑烷二酮类似物的药物组合物。

    All eight stereoisomers of α-tocopheryl acetate have been synthesized in a state of high chemical and stereoisomeric purity. Key chiral side-chain intermediates were prepared from (+)-(S)-3-hydroxy-2-methylpropanoic acid. New routes to (2R, 4′ RS, 8′ RS)-α-tocopheryl acetate, a mixture of four diastereoisomers, were also developed. A sensitive gas chromatographic method was developed to determine the

    affect antioxidant activity, but methylation of the 6-hydroxy substituent resulted in compound 6f which was devoid of antioxidant activity. Although indistinguishable in antioxidant activity, the amide derivatives tended to be more potent as antiproliferative agents than the corresponding esters. The IC50's for the amide derivatives (3, 5a-e, 8) ranged from 2 to 7 microM, while the IC50's for the structurally
    非甾体抗炎药萘普生的一系列酚类抗氧化剂酯和酰胺衍生物被设计为具有抗炎和细胞保护活性。在膜脂质过氧化测定中通过硫代巴比妥酸反应性物质(TBARS)的形成间接评估了化合物的抗氧化活性,并通过抑制了人类血管内皮细胞中DNA的合成来确定其抗增殖活性。该系列化合物表现出有效的抗氧化活性,IC50值(1.6-11.63 microM)比Trolox(6-羟基-2,5,7,8-四甲基苯并二甲酸)和400的IC50值低2-6倍。比维生素E低-1300倍。酯或酰胺亚结构的结构修饰(5a和6a)不影响抗氧化活性,但是6-羟基取代基的甲基化产生了没有抗氧化活性的化合物6f。尽管抗氧化剂活性没有区别,但是酰胺衍生物作为抗增殖剂往往比相应的酯更有效。酰胺衍生物(3、5a-e,8)的IC50范围为2至7 microM,而与结构相关的酯(1、2a-c,6a-e)的IC50范围为9至22 microM。此外,对化合物6a
