A series of biphenylsulfonamide derivatives of (S)-2-(biphenyl-4-sulfonylamino)-3-methylbutyric acid (5) were prepared and evaluated for their ability to inhibit matrix metalloproteinases (MMPs). For this series of compounds, our objective was to systematically replace substituents appended to the biphenyl and alpha-position of 5 with structurally diverse functionalities to assess the effects these
制备了一系列(S)-2-(联苯基-4-磺酰基氨基)-3-甲基丁酸(5)的联苯磺酰胺衍生物,并评估了它们抑制基质金属蛋白酶(MMPs)的能力。对于这一系列化合物,我们的目标是用结构上不同的功能性系统取代取代基上5的联苯和α-位置的取代基,以评估这些变化对生物学和药代动力学活性的影响。随后的结构活性关系(SAR)研究表明,在4'-位(11c)处被溴取代的联苯磺酰胺显着提高了体外活性,并显示出优异的药代动力学(C(max),t(1/2),AUCs,相对于化合物5而言,可以通过用各种取代基取代11c的异丙基来改变α位的亲脂性,一般而言,与MMP-2,-3和-13相比,药效保持不变,但口服系统利用率较低。随后对其对映异构体11c'的评估表明,两种化合物都是同等有效的MMP抑制剂。相反,相应的异羟肟酸对映体对16a(S-异构体)和16a'(R-异构体)立体选择性抑制了MMP。在该系列中,16a'首次提
