Pin1 (protein interacting with never in mitosis A-1) is a member of the peptidyl prolyl isomerase (PPIase) family, and catalyzes cis-trans isomerization of pThr/Ser-Pro amide bonds. Because Pin1 is overexpressed in various cancer cell lines and promotes cell growth, it is considered a target for anticancer agents. Here, we designed and synthesized a covalently binding Pin1 inhibitor (S)-2 to target
Pin1(在有丝分裂A-1中从未相互作用的蛋白质)是肽基脯氨酰异构酶(PPIase)家族的成员,并催化pThr / Ser-Pro酰胺键的顺反异构化。因为Pin1在各种癌细胞系中过表达并促进细胞生长,所以它被认为是抗癌药物的靶标。在这里,我们设计并合成了共价结合Pin1抑制剂(S)-2靶向Pin1的活性位点。如通过ESI-MS测定的,该化合物在蛋白酶偶联测定中抑制Pin1,并与Pin1的Cys113形成共价键。(S)-2的乙酰氧基甲酯,即6,在人前列腺癌PC-3细胞中抑制了细胞周期蛋白D1的表达,并表现出细胞毒性。Pin1-nockdown实验表明,细胞毒性为6的靶标是Pin1。
