tryptophan or its derivatives, and Trp residues in peptides. As demonstrated on several peptides, the aromatic amino acid residues of Trp, Tyr, Phe, and His are targeted with high selectivity to Trp. The functionalization method is biocompatible, mild, rapid, and transition-metal-free. The proteins myoglobin, ubiquitin, and human carbonic anhydrase I were also successfully functionalized.
制备了一系列氟代烷基化的环状λ3-碘化物及其盐酸盐,并与抗坏血酸钠在缓冲液或甲醇水溶液混合物中组合使用,以对一系列取代的吲哚,吡咯,色氨酸或其衍生物以及肽中的Trp残基进行自由基氟代烷基化。 。如在几种肽上所证明的,Trp,Tyr,Phe和His的芳香族氨基酸残基以对Trp的高选择性为目标。该功能化方法具有生物相容性,温和,快速且不含过渡金属。蛋白质肌红蛋白,泛素和人碳酸酐酶I也已成功功能化。
