This invention is directed generally to proteinase (also known as “protease”) inhibitors, and, more particularly, to piperidinyl- and piperazinyl-sulfonylmethyl hydroxamic acids that, inter alia, inhibit matrix metalloproteinase (also known as “matrix metalloprotease” or “MMP”) activity and/or aggrecanase activity. Such hydroxamic acids generally correspond in structure to the following formula:
(wherein A

are as defined in this specification), and further include salts of such compounds. This invention also is directed to compositions of such hydroxamic acids, intermediates for the syntheses of such hydroxamic acids, methods for making such hydroxamic acids, and methods for treating conditions (particularly pathological conditions) associated with MMP activity and/or aggrecanase activity.
这项发明通常涉及蛋白酶抑制剂(也称为“蛋白酶”),更具体地涉及哌啶基和哌嗪基磺酰甲基羟肟酸,该类化合物在结构上抑制基质金属蛋白酶(也称为“基质金属蛋白酶”或“MMP”)活性和/或聚集素酶活性。这类羟肟酸通常对应以下结构式:
(其中A1、A2、Y、E1、E2、E3和Rx如本说明书中所定义),还包括这类化合物的盐。这项发明还涉及这类羟肟酸的组合物、合成这类羟肟酸的中间体、制备这类羟肟酸的方法,以及治疗与MMP活性和/或聚集素酶活性相关的疾病(特别是病理性疾病)的方法。
