    • 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。

    • The invention provides spiro[pyrrolidine-2,3′-oxindole] compounds and libraries of these compounds produced by the stereo- and regio-selective reaction of variously substituted isatins, &agr;-amino acids, and dipolarophiles (e.g., trans-chalcones, acrylate esters, or vinyl oxindoles). The new libraries can be assayed using any of many known screening procedures for activity, e.g., biological activity. For example, the libraries can be screened for activity as drugs (e.g., anticancer drugs, antibiotics, antiviral drugs, antiinflammatory drugs, analgesics, immunomodulators, neuroleptics, sedatives, stimulants, or diagnostic aids), bioseparation agents, or pesticides (e.g., herbicides, insecticides, or rodenticides).
    • 本发明提供了螺[吡咯烷-2,3'-羟吲哚]化合物和这些化合物的文库,其通过各种取代的异头ins素,α-氨基酸和dipolarophicity的立体和区域选择性反应(例如反式查尔酮,丙烯酸酯 酯或乙烯基羟吲哚)。 可以使用许多已知的活性筛选方法(例如生物活性)来测定新的文库。 例如,图书馆可以作为药物(例如,抗癌药物,抗生素,抗病毒药物,抗炎药,止痛剂,免疫调节剂,精神安定药,镇静剂,兴奋剂或诊断辅助剂),生物分离剂或杀虫剂(例如除草剂 ,杀虫剂或杀鼠剂)。
