isomerase that specifically catalyzes cis–trans isomerization of phosphorylated Thr/Ser-Pro peptide bonds in substrate proteins and peptides. Pin1 is involved in many important cellular processes, including cancer progression, so it is a potential target of cancer therapy. We designed and synthesized a novel series of Pin1 inhibitors based on a glutamic acid or aspartic acid scaffold bearing an aromatic
Pin1是一种肽基脯氨酰异构酶,可特异性催化顺式-反式底物蛋白和肽中磷酸化的Thr / Ser-Pro肽键的异构化 Pin1参与许多重要的细胞过程,包括癌症进展,因此它是癌症治疗的潜在靶标。我们设计和合成了一系列新型的Pin1抑制剂,它们是基于带有芳香族部分的谷氨酸或天冬氨酸支架,以提供疏水表面和对Pin1的脯氨酸结合位点具有亲和力的环状脂肪胺部分。具有环烷基氨基和苯基噻唑基团的谷氨酸衍生物显示出与已知抑制剂VER-1相当的有效的Pin1抑制活性。结果表明,环烷基胺部分与结合位点残基的空间相互作用在增强Pin1抑制活性中起关键作用。
