How to use
In Vitro:
OSMI-4 reduces O-GlcNAc levels almost completely by 5 μM. A decrease in HCF-1 cleavage products and the appearance of uncleaved HCF-1 is observed in cells treated with OSMI-4. OSMI-4 is a kind of structure-based evolution of small molecule OGT inhibitors with low nanomolar binding affinities. OSMI-4 exhibits a ~3 μM EC50 in cells, making it especially attractive for probing OGT’s complex biology.
