Description
CAS NO.：2210228-45-6 Product Name：SU0268 Synonyms：SU0268; SU 0268; SU-0268 EINECS: Molecular Formula：C26H25N3O4S Molecular Weight：475.1566
Target:
In Vivo
SU0268 pretreatment (10 mg/kg, intranasally treated) increases survival rates compared with controls without SU0268 pretreatment in MH-S cells and C57BL/6N mice[3]. Animal Model: Anesthetized C57BL/6N mice[3]. Dosage: 10 mg/kg. Administration: Intranasally treated. Result: Significantly inhibits inflammatory responses and mitigates P. aeruginosa infection.
In Vitro
MTH1-depleted cells are less sensitive to the OGG1-specific inhibitor, SU0268 (5-10 μM), than their control shGFP counterparts[1]. SU0268/IACS-4759 (5-20 μM, 48h) co-treated cells are more viable than the correspondingly-treated IACS-4759- or SU0268-treated cells[1]. SU0268 does not bind DNA and thus interacts with OGG1 specifically rather than its substrate[2]. SU0268 induces the release of type I IFN by the mitochondrial DNA-cGAS-STING-IRF3-IFN-β axis, which decreases bacterial loads and halts disease progression[3]. Cell Viability Assay[1] 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.
