  activity with sub-nanomolar potency for some enzymes. Modifications of the P1' portion of the molecule played a key role in affecting both potency and selectivity within the MMP family. Longer-chain aliphatic substituents in this region of the molecule tended to increase potency for MMP-3 and decrease potency for MMP-1, as exemplified by compounds 48-50, while aromatic substituents, as in compound 52, generated

  从氨基脯氨酸支架制备了一系列异羟肟酸酯，并测试了其作为基质金属蛋白酶（MMP）抑制剂的功效。据报道该系列的详细SAR是针对MMP家族中的5种酶，许多抑制剂（例如化合物47）具有广谱活性，某些酶具有亚纳摩尔的效力。分子P1'部分的修饰在影响MMP家族内的效能和选择性方面起着关键作用。如化合物48-50所示，在分子的该区域中的长链脂族取代基倾向于增加对MMP-3的效力而降低对MMP-1的效力，而如化合物52中的芳族取代基产生广谱抑制作用。该数据基于X射线晶体数据也被合理化。虽然体外经口吸收似乎不太可预测，但随着更长和更多亲水性取代基的出现，吸收率往往会降低。最后，使用骨关节炎的大鼠模型评估这些化合物的功效，并在它们的药代动力学和体内功效之间建立了直接联系。
