Ribosomal protein synthesis is an important target in antibacterial drug discovery. Numerous natural products have served as starting points for the development of antibiotics. We report here the total synthesis of xenocoumacin 1, a natural product that binds to 16S ribosomal RNA at a highly conserved region, as well as analogues thereof. Preliminary structure–activity relationship studies were aimed
核糖体蛋白合成是抗菌药物发现的重要目标。许多天然产物已成为抗生素开发的起点。我们在此报告异香豆素 1 的全合成,这是一种在高度保守的区域与 16S 核糖体 RNA 结合的天然产物及其类似物。初步的构效关系研究旨在了解和调节真核和原核核糖体之间的选择性。修饰主要在芳香区域被容忍。对革兰氏阴性菌的全细胞活性受到外排和渗透的限制,正如在大肠杆菌的转基因菌株中所证明的那样. 鉴定了对真核生物核糖体具有高选择性的类似物,但不可能获得对细菌蛋白质合成具有选择性的抑制剂。尽管真核和原核核糖体在结合区具有高度同源性,但实现高选择性(尽管不是理想的)是可能的。
