The present invention relates to compounds that exhibit inhibitory activity against matrix metalloproteases ("MMPs"). Because MMPs are known to play a role in tissue degradation, the compounds of the present invention may be useful in preventing or treating diseases associated with excess MMP activity. In particular, the compounds have a structure according to Formula (I) ##STR1## wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are various substituents as described in the specification; and Q is an alkyl chain, an alkenyl chain, a heteroalkyl chain, or a heteroalkenyl chain, wherein said chain has 2, 3, or 4 chain atoms and is unsubstituted or substituted with one or more alkyl moieties; or a pharmaceutically-acceptable salt, or biohydrolyzable alkoxyamide, acyloxyamide, or imide thereof. Preferred are those compounds where Q is an alkyl chain having 2, 3 or 4 chain atoms. The invention also relates to pharmaceutical compositions comprising these compounds, and methods for preventing or treating diseases associated with unwanted MMP activity using the compounds and compositions.
本发明涉及一种对基质
金属
蛋白酶(“MMPs”)具有抑制活性的化合物。由于MMPs已知在组织降解中发挥作用,本发明的化合物可能有助于预防或治疗与过量MMP活性相关的疾病。特别地,该化合物具有如下结构公式(I):##STR1## 其中R.sup.1、R.sup.2、R.sup.3和R.sup.4是如说明书中所述的各种取代基;Q是烷基链、烯基链、杂原子烷基链或杂原子烯基链,其中该链具有2、3或4个链原子,未取代或取代有一个或多个烷基基团;或其药学上可接受的盐、
生物水解的烷氧酰胺、酰氧酰胺或
酰亚胺。优选的是Q是具有2、3或4个链原子的烷基链。本发明还涉及包含这些化合物的药物组合物,以及使用这些化合物和组合物预防或治疗与不需要的MMP活性相关的疾病的方法。
