A series of sulfonyl amino acyl hydroxamates incorporating alkyl/arylsulfonyl-N-2-nitrobenzyl-L-alanine was prepared. Related compounds were obtained by reaction of N-2-nitrobenzyl-L-Ala with aryl isocyanates, arylsulfonyl isocyanates, or benzoyl isothiocyanate, followed by the conversion of the COOH into the CONHOH moiety. The new compounds were assayed as inhibitors of the Clostridium histolyticum
制备了一系列掺入烷基/芳基磺酰基-N-2-硝基苄基-L-丙氨酸的磺酰基氨基酰基异羟肟酸酯。通过N-2-硝基苄基-L-Ala与芳基异氰酸酯,芳基磺酰基异氰酸酯或苯甲酰基异硫氰酸酯反应,然后将COOH转化为CONHOH部分,得到相关化合物。这些新化合物被测定为溶组织梭状芽孢杆菌胶原酶(ChC)的抑制剂,梭状芽胞杆菌胶原酶是一种参与细胞外基质降解的细菌蛋白酶。许多获得的异羟肟酸酯被证明是有效的细菌胶原酶抑制剂,活性的主要贡献者是磺酰胺基部分的取代模式。最好的ChC抑制剂是那些含有五氟苯基磺酰基以及3-和4-保护的氨基苯基磺酰基P(1)(')基团的抑制剂,亲和力在低纳摩尔范围内。这项研究还证明,与以前研究的4-硝基苯甲基类似(Scozzafava,A .; Supuran,CTJ Med.Chem.2000,43,1858-1865),2-硝基苄基-部分是有效的P(2)( ')用于获得有效的细菌胶原酶抑制剂的锚定部分。
