  摘要：

  流感感染中的抗病毒药物耐药性已成为对公共卫生的主要威胁。为了开发广谱的流感抑制剂来解决耐药性问题，我们之前确定了高度保守的核蛋白三聚体E339 ... R416盐桥为靶标，化合物1为通过EC50破坏盐桥的抑制剂甲型流感病毒= 2.7μM（A / WSN / 1933）。我们通过基于结构的方法进一步修饰了该化合物，并进行了抗病毒活性筛选，以鉴定化合物29和30的EC50值分别为110和120 nM，并且没有可测量的宿主细胞毒性。与临床使用的神经氨酸酶抑制剂相比，这两种化合物对耐药性A型流感病毒株和B型流感病毒显示出更好的活性，

  Ethyl 2-((4-Chlorophenyl)amino)thiazole-4-carboxylate and Derivatives Are Potent Inducers of Oct3/4

  摘要：

  The octamer-binding transcription factor 4 (Oct3/4) is a master gene in the transcriptional regulatory network of pluripotent cells. Repression of Oct3/4 in embryonic stem cells (ESCs) is associated with cell differentiation and loss of pluripotency, whereas forced overexpression in cooperation with other transcriptional factors, such as Nanog, Sox2, and Lin28, can reprogram somatic cells back into pluripotent cells, termed induced pluripotent stem cells (iPSCs). However, random integration and potential tumorigenic transformation caused by viral transduction limit the clinical application of iPSCs. By performing a cell-based high throughput screening (HTS) campaign, we identified several potential small molecules as inducers of Oct3/4 expression. Here we report a lead structure ethyl 2-((4-chlorophenyl)amino)- thiazole-4-carboxylate, termed O4I2, showing high activity in enforcing Oct3/4 expression. On the basis of chemical expansion, we further identified derivatives having increased activities toward Oct3/4 induction. Thus, O4I2 and its derivatives should provide a new class of small molecules suitable for iPSC generation.

To develop a broad-spectrum inhibitor of influenza to combat the problem of drug resistance, we previously identified the highly conserved E339...R416 salt bridge of the nucleoprotein trimer as a target and compound 1 as an inhibitor disrupting the salt bridge with an EC50 = 2.7 μM against influenza A (A/WSN/1933). We have further modified this compound via a structure-based
