    摘要:
    4-羟基噻唑已被确定为体外5-脂氧合酶的有效抑制剂,其IC50值小于1 microM。对结构活性关系的研究表明,该系列最有效的抑制剂是5-苯基衍生物。发现相应的噻唑烷丁-4-酮类似物相对没有活性。在完整的大鼠多形核白细胞和人全血中,4-羟基噻唑都是针对5-脂氧合酶的活性抑制剂。该化合物还是5-脂氧合酶的选择性抑制剂,对其他相关酶环氧合酶和12-和15-脂氧合酶的活性很弱。

    role in its antiepileptic properties. Using this novel molecular target, we initiated a drug-discovery program searching for ligands with significant affinity to LBS with the aim to characterize their therapeutic potential in epilepsy and other central nervous system diseases. We systematically investigated the various positions of the pyrrolidone acetamide scaffold. We found that (i) the carboxamide moiety

    two-step, one-pot reaction of aldehydes with the CAN/LiBr oxidation system under solvent-free conditions followed by the addition of methanol affords methyl α-bromocarboxylates. The oxidation of aldehydes with methanol using this system gives only methyl esters. A facile method, which does not require special equipment, was developed for the synthesis of 2-bromoesters from aliphatic aldehydes with carbon

  • SYNTHESIS OF 2,4-THIAZOLIDINEDIONE-2-AZINES AND 2,4-THIAZOLIDINEDIONE-2-DIMETHYLHYDRAZONES FROM THIOCYANOESTERS AND HYDRAZINES
    作者:Paul E. Gagnon、Jean-L. Boivin、Gordon M. Brown
    DOI:10.1139/v59-231
    日期:1959.9.1

    Thiocyanoesters were prepared from 2-bromoesters and potassium thiocyanate, and a series of substituted thiazolidinedione-2-azines was obtained from these thiocyanoesters using hydrazine hydrate. The structure of the thiazolidinedione-2-azines was determined by hydrolysis using hydrochloric acid in ethanol. The reaction of thiocyanoesters with dimethylhydrazine, generally speaking, was analogous to their reaction with hydrazine, but there were many differences. Only 1 mole of alcohol was eliminated rather than 2, and there was no apparent reaction for the ethyl 2-thiocyanononanoate and the methyl phenylthiocyanoacetate. Furthermore, the reaction of methyl 2-thiocyanoisobutyrate with dimethylhydrazine did not give a 2,4-thiazolidinedione-2-dimethylhydrazone but rather an addition product, N-dimethylamino-S-(1-methyl-1-carbomethoxy) ethylisothiourea. To illustrate the reactivity of the thiocyano group, benzyl thiocyanate was treated with hydrazine and the product was found to be dibenzyldisulphide, and ammonia was evolved. Similarly, trimethylene dithiocyanate gave the dimer of trimethylene disulphide. Finally, benzyl thiocyanate formed an addition product with dimethylhydrazine which was N-dimethylamino-S-benzylthiourea.

    硫氰酸酯由2-溴酯和硫氰酸钾制备,并通过硫氰酸酯与水合肼反应获得一系列取代的噻唑烷二酮-2-嗪。噻唑烷二酮-2-嗪的结构通过在乙醇中使用盐酸水解确定。硫氰酸酯与二甲基肼的反应,一般来说,类似于它们与肼的反应,但存在许多差异。只有1摩尔的醇被消除而不是2摩尔,并且乙基2-硫氰基壬酸酯和甲基苯基硫氰基乙酸酯没有明显的反应。此外,甲基2-硫氰基异丁酸酯与二甲基肼的反应没有生成2,4-噻唑烷二酮-2-二甲基脒,而是生成了加成产物,N-二甲氨基-S-(1-甲基-1-羰基甲氧基)乙基异硫脲。为了说明硫氰酸基团的反应性,苯基硫氰酸酯与肼反应,产物被发现是二苯基二硫化物,并释放出氨。同样,三甲基二硫氰酸酯生成了三甲基二硫化物的二聚体。最后,苯基硫氰酸酯与二甲基肼形成了一个加成产物,即N-二甲氨基-S-苯基硫脲。
