OSMI-3
Based on 1 Customer Validation
OSMI-3 (Compound 2b) is a potent, long-lasting, and cell-permeable O-linked N-acetylglucosamine transferase (OGT) inhibitor. Cells contain a large nuclear pool of partially spliced OGT transcript, and OSMI-3 increases detained intron splicing in cells.

Biological Activity
O-linked N-acetylglucosamine transferase (OGT)[1]
OSMI-3 (Compound 2b; 20-50 μM; 4-24 hours; HCT116 cells) treatment significantly reduces O-GlcNAc levels, and has more sustained cellular effects than OSMI-2[1].
A decrease in HCF-1 cleavage products and the appearance of uncleaved HCF-1 in cells treated with OSMI-3 (Compound 2b) is observed. Because OGT knockdown is known to decrease cell proliferation, the effects of OSMI-3 on cell growth in culture over 96h is also monitored. Although there is no evidence of apoptosis, the reduced growth of cells over time is observed, consistent with the knockdown results[1].
