  摘要：

  制备一系列新颖的1，4-取代的氨基脲5a-g，其具有在位置1的羰基桥接的伯氨喹部分和在位置4的环烷基，芳基，苄氧基或羟基取代基，并进行了生物学评估。用于制备标题化合物的合成途径涉及苯并三唑作为合成助剂。评估了伯氨喹氨基脲5a-g及其合成前体苯并三唑羰基氨基脲4的抑制细胞生长，抗病毒和抗氧化活性。第5系列的所有化合物均对MCF-7细胞（乳腺癌）表现出高选择性，IC（50）值在低微摩尔范围内，而活性最高的是苄基衍生物5c（IC（50）1±0.2 µM）。苯甲酰基衍生物5e对所有测试的细胞系（IC（50）4-18 µM）均显示出显着的细胞抑制活性。同样的化合物也是最强的脂氧合酶抑制剂（51％）。羟基衍生物5g和苯并三唑羰基氨基脲4b，c（61.2-68.5％）的抗氧化剂活性最高。没有观察到针对多种DNA和RNA病毒的抗病毒活性。

  Semicarbazone-based inhibitors of cathepsin K, are they prodrugs for aldehyde inhibitors?

  摘要：

  Starting from potent aldehyde inhibitors with poor drug properties, derivatization to semicarbazones led to the identification of a series of semicarbazone-based cathepsin K inhibitors with greater solubility and better pharmacokinetic profiles than their parent aldehydes. Furthermore, a representative semicarbazone inhibitor attenuated bone resorption in an ex vivo rat calvarial bone resorption model. However, based on enzyme inhibition comparisons at neutral pH, semicarbazone hydrolysis rates, and 13C NMR experiments, these semicarbazones probably function as prodrugs of aldehydes.

  As part of an ongoing program on the chemistry and biological activity of N-oxide-containing molecules, a number of novel 1,2, 5-oxadiazole N-oxide, benzo[1,2-c]1,2,5-oxadiazole N-oxide, and quinoxaline N,N'-dioxide derivatives were synthesized and evaluated for their herbicidal activity. Many of these compounds exhibited moderate to good herbicidal pre-emergence activity against Triticum aestivum

  作为正在进行的有关含氮氧化物分子化学和生物学活性的计划的一部分，许多新型的1,2,5-恶二唑N-氧化物，苯并[1,2-c] 1,2,5-恶二唑合成了N-氧化物和喹喔啉N，N'-二氧化物衍生物，并对其除草活性进行了评估。这些化合物中有许多对普通小麦表现出中等至良好的除草前出苗活性。在更具代表性的化合物（12、20和26）上进行了剂量反应研究。活性最强的丁基氨基甲酰基苯并[1,2-c] 1,2,5-恶二唑N-氧化物26在低至24 g / ha的浓度下表现出除草活性。

  Several novel semicarbazones derivatives were prepared from 5-nitro-2-furaldehyde or 5-nitrothiophene-2-carboxaldehyde, and tested in vitro as potential anti trypanosomal agents. The compounds were prepared in good to excellent yields in 2-3 steps from readily available starting materials. Some derivatives were found to be active against Trypanosoma cruzi with an activity similar to that of Nifurtimox. (C) 1998 Elsevier Science S.A. All rights reserved.
