    The present invention relates to compounds of Formula I or II, or a pharmaceutically acceptable salt, ester, or prodrug, thereof: 1 which inhibit serine protease activity, particularly the activity of hepatitis C virus (HCV) NS3-NS4A protease. Consequently, the compounds of the present invention interfere with the life cycle of the hepatitis C virus and are also useful as antiviral agents. The present invention further relates to pharmaceutical compositions comprising the aforementioned compounds for administration to a subject suffering from HCV infection. The invention also relates to methods of treating an HCV infection in a subject by administering a pharmaceutical composition comprising the compounds of the present invention.
    本发明涉及式I或II的化合物,或其药学上可接受的盐、酯或前药:1,其抑制丝氨酸蛋白酶活性,特别是乙型肝炎病毒(HCV)NS3-NS4A蛋白酶的活性。因此,本发明的化合物干扰乙型肝炎病毒的生命周期,并且也可用作抗病毒剂。本发明还涉及含有上述化合物的药物组合物,用于治疗患有HCV感染的受试者。该发明还涉及通过给受试者投予含有本发明化合物的药物组合物来治疗HCV感染的方法。

    4-dihydroquinoxalin-2(1H)-one regioselectivity in a predictable manner. For comparison, all regioselective cyclocondensations were performed with the same standardized conditions (DMF, rt, 3 days), differing only by the additives p-TsOH or HOBt/DIC (hydroxybenzotriazole/N,N'-diisopropylcarbodiimide). Both selected methods are simple, general and highly regioselective (72-97%). A mechanism for the regioselectivity was
    3-酰基亚甲基-3,4-二氢喹喔啉-2(1H)-1是具有广泛的物理和药物应用的化合物。这些化合物可以通过邻苯二胺和芳酰基丙酮酸酯的环缩反应容易地制备。不对称取代的邻苯二胺可以从3,4-二氢喹喔啉-2(1H)-一的区域异构体混合物中获得。在不控制反应选择性和利用复杂的NMR技术(HSQC,NOESY,HMBC)的情况下,获得纯的区域异构体并确定其结构通常非常困难。本文研究了我们研究的六个单取代的邻苯二胺(-OMe,-F,-Cl,-COOH,-CN,-NO2)与对氯苯甲酰基丙酮酸(酯或酸)衍生物之间的环缩反应的区域选择性。六个区域异构体3 选择性地制备并表征了4-二氢喹喔啉-2(1H)-对。根据我们的经验,提出了一种用于确定区域异构体结构的简化方法。我们从相同的邻苯二胺和活化的4-氯苯甲酰基丙酮酸酯(酯或酸)开发了两种通用且高度选择性的方法,从而能够以可预测的方式切换3,4-二氢喹喔啉-2(1
