Discovery of cell-permeable OGT inhibitors is significant to clarify the function and regulatory mechanism of O-GlcNAcylation. This will establish the foundation for the development of therapeutic drugs for relevant diseases. Here, we report two cell-permeable OGT inhibitors (APNT and APBT), developed from low-activity precursors (IC50 > 1 mM) via “tethering in situ click chemistry (TISCC)”. Both of them were
O- GlcNAc转移酶(OGT)是一种关键酶,与磷酸化相似,参与核蛋白和细胞质蛋白的动态O -GlcNAcy环化。发现细胞可渗透的OGT抑制剂对于阐明O- GlcNAcylation的功能和调节机制具有重要意义。这将为开发相关疾病的治疗药物奠定基础。在这里,我们报告了通过“束缚原位点击化学(TISCC)”从低活性前体(IC 50 > 1 mM)开发的两种可渗透细胞的OGT抑制剂(APNT和APBT)。他们俩都能够抑制O-GlcNAcylation在细胞中对细胞活力没有明显影响。OGT的非竞争性非常规抑制作用有助于发现新型抑制剂并探索OGT的调节机制。这些分子的发展证实,TISCC可用于从与靶标结合力很弱的组分中发现新的先导化合物。
