Defective in cullin neddylation 1(DCN1) is a co-E3 ligase that is important for cullin neddylation. Dysregulation of DCN1 highly correlates with the development of various cancers. Herein, from the initial high-throughput screening, a novel hit compound 5a containing a phenyltriazole thiol core (IC50 value of 0.95 μM for DCN1-UBC12 interaction) was discovered. Further structure-based optimization leads
cullin neddylation 1(DCN1)中的缺陷是co-E3连接酶,对cullin neddylation很重要。DCN1的失调与各种癌症的发生高度相关。在此,从最初的高通量筛选中,发现了含有苯基三唑硫醇核(对于DCN1-UBC12相互作用的IC 50值为0.95μM)的新型命中化合物5a。进一步的基于结构的优化导致了SK-464的发展(IC 50值为26 nM)。我们发现SK-464不仅在体外直接与DCN1结合,但也参与细胞DCN1,抑制cullin3的二联化,并阻碍了两个DCN1过表达的鳞状癌细胞系(KYSE70和H2170)的迁移和侵袭。这些发现表明,SK-464可能是靶向DCN1-UBC12相互作用的新型先导化合物。
