solid phase peptide synthesis and acid-labile groups such as trityl (Trt) and tBu, which empowers the solid phase synthesis of sulfonamides of various peptides. To illustrate this, the syntheses of three sulfonamide derivatives of the peptide GAILG-NH2, which is relevant in the context of drug design against type 2 diabetes, are demonstrated by using Fmoc-based solid-phase peptide synthesis (SPPS).
报道了一种通过将磺酸基活化为相应的 2-氰基-2-(羟基亚氨基)乙酸乙酯 (Oxyma) 磺酸酯来合成磺胺类药物的更温和、更有效的方法。为此,此方法比所有其他现有协议更环保。其他重要优势在于 (a) 在环境和温和条件下适用于亲核性较低的苯胺,以及 (b) 与固相肽合成和酸不稳定基团如三苯甲基 (Trt) 和 tBu 的相容性,这使固相合成成为可能各种肽的磺胺类药物。为了说明这一点,使用基于 Fmoc 的固相肽合成 (SPPS) 证明了肽 GAILG-NH2 的三种磺酰胺衍生物的合成,这与治疗 2 型糖尿病的药物设计相关。
