UNC0646 is a potent and selective histone lysine methyltransferase inhibitor targeting G9a and GLP. By inhibiting G9a and GLP enzymatic activity, UNC0646 reduces cellular levels of histone H3 lysine 9 dimethylation (H3K9me2). This selective target inhibition alters chromatin structure and regulates epigenetic gene expression, resulting in suppressed cell proliferation in various cancer cell models while demonstrating a favorable functional potency window over general cellular toxicity.

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).
