Biological Activity
| Description | OSMI-4 is an inhibitor of O-linked N-acetylglucosamine transferase (O-GlcNAc transferase, OGT) with EC50 of 3 μM in cells. | ||

| 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.[1] |
