Abstract

A series of bis-(arylsulfonamide) hydroxamate inhibitors were synthesized. These compounds exhibit good potency against MMP-7 and MMP-9 depending on the nature, steric bulk, and substitution pattern of the substituents in the benzene ring. In general, the preliminary structure-activity relationships (SAR) suggest that among the DAPA hydroxamates (i) electron-rich benzene rings of the sulfonamides may produce better inhibitors than electron-poor analogs. However, potential H-bond acceptors can reverse the trend depending on the isozyme; (ii) isozyme selectivity between MMP-7 and -9 can be conferred through steric bulk and substitution pattern of the substituents in the benzene ring, and (iii) the MMP-10 inhibition pattern of the compounds paralleled that for MMP-9.

摘要

合成了一系列双(芳基磺酰胺)异羟肟酸酯抑制剂。根据苯环上取代基的性质、空间位阻和取代模式,这些化合物对基质金属蛋白酶-7(MMP-7)和基质金属蛋白酶-9(MMP-9)表现出良好的活性。一般来说,初步的构效关系(SAR)表明,在二氨基苯丙氨酸异羟肟酸酯中:(i)磺酰胺的富电子苯环比缺电子类似物可能产生更好的抑制剂。然而,潜在的氢键受体可根据同工酶逆转这一趋势;(ii)MMP-7和MMP-9之间的同工酶选择性可通过苯环上取代基的空间位阻和取代模式来赋予,并且(iii)这些化合物对MMP-10的抑制模式与对MMP-9的抑制模式相似。
