Description: O4I2 is a potent inducers of Oct3/4. O4I2 showed high activity in enforcing Oct3/4 expression. O4I2 is a new class of small molecules suitable for iPSC generation. 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).

| Biological target: | O4I2 is a potent Oct3/4 inducer that induces the expression of pluripotent-associated genes Lin28, Sox2 and Nanog, and suppresses Rex1. |
| In vitro activity: | 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, several potential small molecules were identified as inducers of Oct3/4 expression. A lead structure ethyl 2-((4-chlorophenyl)amino)-thiazole-4-carboxylate, termed O4I2 was reported, showing high activity in enforcing Oct3/4 expression. On the basis of chemical expansion, further derivatives having increased activities toward Oct3/4 induction have been identified. Thus, O4I2 and its derivatives should provide a new class of small molecules suitable for iPSC generation. J Med Chem. 2015 Aug 13;58(15):5742-50. https://pubmed.ncbi.nlm.nih.gov/26143659/ |
