The present invention relates to a method of forming a macrocyclic peptide bearing a pharmacophore and said produced macrocyclic peptide, wherein the method comprises the steps of: reacting a peptide with two thiol groups of cysteine side chains with the reactive compound 1,5 -dichloropentanedion-2,4. The reaction between the reactive compound and the peptide produces an 1,3 -diketone-containing macrocyclic polypeptide. The macrocycle with a 1,3 -diketone group is then modified by reaction of said macrocycle with an alkyl or aryl hydrazine group bearing a pharmacophore in benign aqueous conditions. The macrocycles may be displayed in a library, such as a phage display library, and used to biopan for affinity against a selected target.
本发明涉及一种制备带有药效团的大环肽的方法以及所制备的大环肽,其中该方法包括以下步骤:将含有两个半胱氨酸侧链巯基的肽与反应性化合物1,5-二氯戊二酮-2,4反应。反应生成含有1,3-二酮的大环多肽。然后,在良性水溶液条件下,将带有药效团的烷基或芳基肼基与该大环化合物反应,以修饰带有1,3-二酮基团的大环。这些大环化合物可以在库中展示,例如噬菌体展示库中,用于对所选目标进行亲和力生物筛选。
