    • &agr;,&bgr;-Unsaturated amides and esters are converted to &agr;,&bgr;-substituted amino amides, esters, and acids. An &agr;,&bgr;unsaturated amide or ester is first converted to an &agr;,&bgr;-hydroxysulfonamide or hydroxycarbamate amide or ester using an osmium-catalyzed aminohydroxylation. The &agr;,&bgr;-hydroxysulfonamide or hydroxycarbamate amides or esters is then cyclodehydrated to produce a &agr;,&bgr;-N-sulfonyl- or the &agr;,&bgr;-N-carbamoylaziridine amide or ester. The ring of aziridine intermediate is then nucleophilically opened in a regioselective manner with a variety of nucleophiles to give the $g(&agr;,&bgr;-substituted amino- amides or esters. Preferred nucleophiles include sulfur, oxygen, carbon, and nitrogen nucleophiles.
    • α,β-不饱和酰胺和酯转化为α,β-取代的氨基酰胺,酯和酸。 首先使用锇催化的氨基羟基化将α,β-不饱和酰胺或酯转化为α,β-羟基磺酰胺或羟基氨基甲酸酯酰胺或酯。 然后将α,β-羟基磺酰胺或羟基氨基甲酸酯酰胺或酯环化脱水以产生α,β-N-磺酰基或α,β-N-氨基甲酰基氮丙啶酰胺或酯。 然后将氮丙啶中间体环以区域选择性方式用各种亲核试剂进行亲核打开,得到$ g(α,β-取代的氨基酰胺或酯)。优选的亲核试剂包括硫,氧,碳和氮亲核试剂。

    • The invention is based on new methods for making and using compounds and arrays of novel &agr;-ketoamides, and the arrays and compounds made by these methods. These novel compounds are potential inhibitors of proteolytic enzymes, particularly cysteine proteases such as cruzain. Application of the new methods has led to the identification of a number of new inhibitors, from amongst an array of about 38,000 &agr;-ketoamide derivatives, having specific activity against three cysteine proteases: cruzain, papain, and cathepsin B. These compounds and other compounds identified by the methods described herein can be useful, for example, in developing pharmaceutical agents for the treatment of diseases (e.g., Chagas' disease) associated with these proteases. Although the disclosed compounds have specific activity for cruzain, papain, cathepsin B, the methods described herein can also be used to identify inhibitors of other proteases.
    • 本发明基于制备和使用新型α-酮酰胺的化合物和阵列的新方法,以及通过这些方法制备的阵列和化合物。 这些新型化合物是蛋白水解酶的潜在抑制剂,特别是半胱氨酸蛋白酶如克鲁津。 新方法的应用已经导致了一系列新的抑制剂的鉴定,其中有大约38,000个α-酮酰胺衍生物,具有针对三个半胱氨酸蛋白酶:克鲁津,木瓜蛋白酶和组织蛋白酶B的比活性。这些化合物和其它化合物 通过本文所述的方法鉴定可用于例如开发用于治疗与这些蛋白酶相关的疾病(例如恰加斯病)的药剂。 虽然所公开的化合物对克鲁津,木瓜蛋白酶,组织蛋白酶B具有比活性,但本文所述的方法也可用于鉴定其它蛋白酶的抑制剂。
