    Cinnoline derivatives as human neutrophil elastase inhibitors
    摘要:
    Compounds that can effectively inhibit the proteolytic activity of human neutrophil elastase (HNE) represent promising therapeutics for treatment of inflammatory diseases. We present here the synthesis, structure-activity relationship analysis, and biological evaluation of a new series of HNE inhibitors with a cinnoline scaffold. These compounds exhibited HNE inhibitory activity but had lower potency compared to N-benzoylindazoles previously reported by us. On the other hand, they exhibited increased stability in aqueous solution. The most potent compound, 18a, had a good balance between HNE inhibitory activity (IC50 value = 56 nM) and chemical stability (t(1/2) = 114 min). Analysis of reaction kinetics revealed that these cinnoline derivatives were reversible competitive inhibitors of HNE. Furthermore, molecular docking studies of the active products into the HNE binding site revealed two types of HNE inhibitors: molecules with cinnolin-4(1H)-one scaffold, which were attacked by the HNE Ser195 hydroxyl group at the amido moiety, and cinnoline derivatives containing an ester function at C-4, which is the point of attack of Ser195.

    三氮烯掩盖的重氮离子的Richter环化和共环​​化反应
    摘要:
    常规的Richter环化涉及将2-炔基苯胺与HX(aq)(X = Br或Cl)和NaNO 2重氮化,然后自发闭环,得到4-卤代辛啉和4-cinnolinone产物的混合物。不同的产品来自竞争X的攻击导致-和H 2中的环化步骤分别O,中,在中间-2-炔基苯基重氮离子。为了提高该反应的化学选择性,我们利用三氮烯作为掩蔽的重氮离子。这些可以使用MeSO 3进行屏蔽在无水溶剂中的氢和所得的2-炔基苯基重氮鎓离子通过掺入专门添加的亲核试剂进行化学选择性环化。此过程已扩展到拴系的亲核试剂,导致Richter诱导的共环化过程产生环稠合的cinnolines。
