SU0268 is a potent inhibitor of 8-oxoguanine DNA glycosylase 1 (OGG1), an enzyme essential for repairing 8-oxoguanine DNA lesions generated by oxidative stress. By inhibiting OGG1 enzymatic activity, SU0268 impairs base excision repair pathways and disrupts OGG1-mediated transcriptional regulation. Downstream, target engagement reduces the expression of pro-inflammatory genes and attenuates inflammatory signaling responses in cellular models of oxidative damage. [1]

Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
- Preheat media/saline to 37°C.
- Mix rapidly (pipette/vortex) upon addition.
- For complex mixes, always add the aqueous phase last.
- Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
