6-APA derivatives were considered as selective labels for the construction of bifunctional linkers dedicated to the oriented immobilization of proteins on materials. Sulbactam-like compounds (i.e., 6-β-sulfonamido-penam sulfones) and penicillin G—like compounds (i.e., para-substituted 6-β-phenylacetamido-penams) were prepared and tested as irreversible inhibitors of representative β-lactamases and
6-APA衍生物被认为是构建双功能接头的选择性标记,该接头专门用于将蛋白质定向固定在材料上。制备了类似舒巴坦的化合物(即6-β-磺酰胺基-penam砜)和青霉素G的化合物(即对位取代的6-β-苯基乙酰胺基-penams),并作为代表性的β-内酰胺酶和D的不可逆抑制剂进行了测试。 ,D-肽酶,分别。尽管被各种锚定臂取代,但修饰的抗生素的活性得以保留。由于(2-硝基-4,5-二甲氧基)-苄基酯能够酰化BlaR-CTD而不脱保护的能力,因此引起了人们的特别关注。
