| 产品描述: | SU0268 is a potent and specific inhibitor of 8-Oxoguanine DNA glycosylase 1 (OGG1). SU0268 regulates inflammatory responses during Pseudomonas aeruginosa infection |
| 体外研究: |
mth1缺失的细胞对 ogg1 特异性抑制剂 SU0268 (5-10 μM) 的敏感性低于对照 shGFP。 SU0268 /IACS-4759 (5- 20 μM,48h) 共同处理的细胞比相应处理的 IACS-4759 或 SU0268 处理的细胞更有活力。 不结合DNA,因此与 OGG1 特异性反应而不是其底物相互作用。 SU0268 诱导线粒体 DNA-cGAS-STING-IRF3-IFN-β 轴释放 I 型干扰素,从而减少细菌负荷和阻止疾病进展 Cell Viability Assay Cell Line: A549 shGFP and shMTH1 (2000 cells per well). Concentration: 0.1 μM, 0.5 μM, 1 μM, 2.5 μM, 5 μM, 7.5 μM, 10 μM. Incubation Time: 24 or 48 h. Result: The shGFP cells were more susceptible to OGG1 inhibition via increasing SU0268 doses than the shMTH1 cells, especially at the 48 time-point. |
| 体内研究: |
与未进行 SU0268 预处理的对照组相比,SU0268 预处理 (10 mg/kg,鼻内处理) 可提高 MH-S 细胞和 C57BL/6N 小鼠的存活率。 Animal Model: Anesthetized C57BL/6N mice. Dosage: 10 mg/kg. Administration: Intranasally treated. Result: Significantly inhibits inflammatory responses and mitigates P. aeruginosa infection. |
