OSMI-1

Research use only, not for human use.

OSMI-1 inhibits protein O-linked N-acetylglucosamine (O-GlcNAcylation) in several mammalian cell lines without qualitatively altering cell surface N- or O-linked glycans.

OSMI-1 inhibits protein O-linked N-acetylglucosamine (O-GlcNAcylation) in several mammalian cell lines without qualitatively altering cell surface N- or O-linked glycans. OSMI-1 is a cell-permeable O-GlcNAc transferase (OGT) inhibitor (IC50: 2.7 μM).

OSMI-1 (50 μM; 24 hours; CHO cells) treatment decreases the viability by about 50% after 24 hours.OSMI-1 (10-100 μM; 24 hours; CHO cells) treatment reduces global O-linked N-acetylglucosamine (O-GlcNAcylation) a dose-dependent manner. OSMI-1 inhibits OGT activity in cells. Cell Viability Assay Cell Line:CHO cells Concentration:50 μM Incubation Time:24 hours Result:Viability decreased by about 50% after 24 hours.Western Blot Analysis Cell Line:CHO cells Concentration:10 μM, 25 μM, 50 μM, 100 μM Incubation Time:24 hours Result:Reduced global OGlcNAcylation in a dose-dependent manner.

Mammalian and zebrafish toxicity profiles are strikingly similar, and zebrafish can usually serve as an intermediate step between cell-based evaluation and conventional animal testing. The zebrafish model is used to investigate OSM1-1 acute toxicity in vivo. The LC50 of OSM1-1 is 0.031?mg/mL (56?μM, 12?h) and 0.025?mg/mL (45?μM, 24?h) in zebrafish model.
