We report an efficient and versatile solid-phase synthesis through which two series of chlorofusin analogues, one bearing varying chromophores and the other with various amino acid substitutions in the cyclic peptide, were synthesized. These peptides were prepared using a strategy involving side-chain immobilization, on-resin cyclization, and postcyclization modification. The success of these syntheses
我们报告了一种有效而通用的固相合成方法,通过该方法合成了两个系列的氯夫西林类似物,一个带有变化的生色团,另一个带有环状肽中的多种氨基酸取代基。使用涉及侧链固定,树脂上环化和环化后修饰的策略制备这些肽。这些合成方法的成功证明了该方法的广泛实用性。评价了两个系列的类似物对p53 / MDM2相互作用的抑制活性,但显示在所测试的浓度范围内是无活性的。这表明活性可能需要完整的生色团结构。
