体内（毎回新しく調製した物を用意してください）

Homogeneous suspension	CMC-NA	≥5mg/ml	Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.
Clear solution	5% DMSO 1 20% PEG300 2 3%Tween80 3 72%ddH2O この製剤はselleckのラボで検証済みです。上記の溶解方法がご要望を満たさない場合、selleckの営業担当までお問い合わせ頂ければ、個別の試験を行います。	5.000mg/ml (8.28mM)	Taking the 1 mL working solution as an example, add 50 μL of 100 mg/ml clarified DMSO stock solution to 200 μL of PEG300, mix evenly to clarify it; add 30 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 720 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明	OSMI-4は、細胞におけるEC50が3 μMのO-結合型N-アセチルグルコサミントランスフェラーゼ（O-GlcNAcトランスフェラーゼ、OGT）の阻害剤です。
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 this compound. This chemical is a kind of structure-based evolution of small molecule OGT inhibitors with low nanomolar binding affinities. It exhibits a ~3 μM EC50 in cells, making it especially attractive for probing OGT’s complex biology.

細胞アッセイ	細胞株	HEK293T cells
	濃度	5 μM, 10 μM, 20 μM
	反応時間	2 h, 8 h, 16 h, 24 h
	実験の流れ	For quantitative analysis of the proteome, HEK293T cells in fresh media (changed 3 hours before treatment) are treated with 5 and 20 μM OSMI-4 in triplicates, and 10 μM in duplicates (11-plex) or DMSO for 8 hours, 16 hours or 24 hours. At the indicated time point, cells are lysed in lysis buffer (2 % SDS 50 mM Tris-HCl and 150 mM NaCl), sonicated and protein concentration determined with the BCA assay.
