  摘要：

  新型纤细且形状丰富的富含sp3的氮杂环系统是在铅发现中扩展分子多样性的广受欢迎的平台。本工作描述了迄今为止未知的3-甲基硫基-5,6,7,8-四氢-1H- [1,2,4]三唑并[1,2-a]哒嗪2的一系列衍生物的合成和表征。此方法由一项计算研究指导，旨在优化先前报道的已知抑制诱导型一氧化氮合酶（iNOS）的[1,2,4]三唑并[1,2-a]哒嗪-1-硫酮1。在温和条件下通过化合物1的甲基化可得到标题化合物。使用RINm5F细胞，通过与应用于1型先前产品相同的基于细胞的分析，对产品进行了生物学评估，在促炎细胞因子IL-1β和IFN-γ的作用下刺激它们产生NO。化合物2在所选测定中未显示出预期的iNOS抑制活性的改善，但有助于该领域的SAR。另外，已经研究了通过氧化前所未有地形成副产物3。新颖的支架代表了构建各种分子的有吸引力的起点，这些分子与基于扁平和亲脂性芳族支架的已知化合物有很大不同。

  Investigations on synthesis and structure elucidation of novel [1,2,4]triazolo[1,2-a]pyridazine-1-thiones and their inhibitory activity against inducible nitric oxide synthase

  摘要：

  The inducible nitric oxide synthase (iNOS) is a target of great research interest due to its importance in a number of diseases, for example, septic shock and inflammatory lung diseases. A variety of 3-substituted [1,2,4]triazolo[1,2-a]pyridazine derivatives was synthesized by ring closure with hexahydropyridazinel-1-carbothioamide by using aliphatic and aromatic aldehydes. The activity of the new substances was tested on the insulin-secreting rat insulinoma cell line RINm5F. iNOS was expressed through exposure to interleukin-1 beta (IL-1 beta) and interferon-gamma (IFN-gamma). A number of the investigated compounds were more active than the reference inhibitor aminoguanidine (AG). Structure-activity relationships showed that a phenyl substituent in position 3 is apparently essential for inhibition. (C) 2013 Elsevier Ltd. All rights reserved.

  Novel slim and shapely sp3-rich nitrogen containing heterocyclic ring systems are sought-after platforms for the expansion of molecular diversity in lead discovery. The present work describes the synthesis and characterization of a series of derivatives of hitherto unknown 3-methylsulfanyl-5,6,7,8-tetrahydro-1H-[1,2,4]triazolo[1,2-a]pyridazines 2. This approach was guided by a computational study,
