OSMI-2 (Compound 1b; 20-50 μM; 4-24 hours; HCT116 cells) treatment reduces O-GlcNAc levels at short treatment times (<8h). However, O-GlcNAc levels begins to recover at longer treatment times with OSMI-2[1].A decrease in HCF-1 cleavage products and the appearance of uncleaved HCF-1 in cells treated with OSMI-2 (Compound 1b) is observed. Because OGT knockdown is known to decrease cell proliferation, the effects of OSMI-2 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].
A time course performed with 20 μM OSMI-2 (Compound 1b) shows reciprocal changes in the abundance of OGT and OGA, with a particularly large increase in OGT; this may explain the recovery in O-GlcNAc levels with OSMI-2. At 24h where O-GlcNAc levels fully recovered[1].

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL saline, mix and clarify.
Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.
Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
