≥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.
* <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 Thiamet G is a potent, selective O-GlcNAcase inhibitor with Kiof 21 nM, while exhibiting 37,000-fold selectivity over human lysosomal –hexosaminidase.
in vitro In NGF-differentiated PC-12 cells, inhibition of O-GlcNAcase by Thiamet G increases the cellular levels of O-GlcNAc with EC50 of approximately 30 nM. This compound (100 mM) reduces tau phosphorylation by approximately 2.1-fold, 2.7-fold, 1.2-fold and 1.3-fold for Ser396, Thr231, Ser422 and Ser262, respectively. [1] It (12.5 nM and 25 nM) significantly enhances p38 phosphorylation by increasing O-GlcNAcylation in mesangial cells. [2] In O-GlcNAc transferase or O-GlcNAcase gain of function cells, this compound restores the assembly of the spindle and partially rescues histone phosphorylation. [3]
in vivo In rats, thiamet G (50 mg/kg) administrated by i.v. crosses the blood brain barrier and then results in increase in brain O-GlcNAc levels in a dose- and time-dependent manner, and reduction of tau phosphorylation in rat brain. This compound is also orally bioavailable. [1] O-GlcNAc accumulation induced by this chemical stimulates chondrogenic differentiation in C57/bl mice by increasing the gene expression of differentiation markers, as well as the activity of MMP-2 and -9.

キナーゼアッセイ Kinetic Analysis with O-GlcNAcase
All assays are carried out in triplicate at 37 °C using para-nitrophenyl β-2-acetamido-2-deoxy-D-glucopyranoside (pNP-GlcNAc) as a substrate in a continuous assay procedure in which the linear rate of liberation of 4-nitrophenolate is monitored by measuring the absorption at 400 nm using a Varian Cary 3E UV-VIS spectrophotometer equipped with a Peltier temperature controller. Reactions (final volume of 50 μL) are initiated by the addition, via syringe, of enzyme (3 μL, 0.27 μg/mL final concentration) and monitored for 5 minutes. Recombinant human O-GlcNAcase is stable in the assay buffer (50 mM NaPi, 100 mM NaCl, 0.1% BSA, pH 7.4) over the time period of the assay. Thiamet G is tested at six concentrations ranging from 0 to 160 nM. The Ki value is determined by linear regression of data from a Dixon plot.
