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.

* <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	PluriSIn #1 is an inhibitor of the stearoyl-coA desaturase 1 (SCD1), which is able to selectively eliminate hPSCs.
in vitro	PluriSIn #1 (NSC 14613) has a robust, rapid, and selective cytotoxic effect toward hPSCs, with apoptosis as the central cell death mechanism it activates. This compound leads to ER stress in hPSCs, induces a ~30% decrease in protein synthesis at 20 μM, and causes a ~65% decrease in stearoyl-coA desaturase (SCD1) activity. It also prevents teratoma formation from undifferentiated hPSCs at 20 μM. PluriSIns inhibit mPSCs and hinder mouse embryonic development. ^[1]

キナーゼアッセイ	SCD1 activity assays
キナーゼアッセイ	Cells are plated in 6-well plates at a density of 50k to 100k cells per well. 24 h later, 20 μM of PluriSIn #1 (NSC 14613) or 0.2% DMSO-control are added to the cells. After 12 h of incubation at 37 ℃, 5% CO₂, the old medium is removed, cells are washed with PBS, and new medium containing 2.3 μM of 0.75 UCi [1-¹⁴C] Stearic Acid is added. The cells are incubated for up to 4 h at 37 ℃, 5% CO₂. After the incubation period, the medium is discarded and the cells are washed 3 times with 2 mL of PBS. 2 mL of the mixture n-hexane: isopropanol (3:2 v:v) are added, and the cells are incubated for 30 min at 37 ℃, 5% CO₂. 2 mL Folch solution (chloroform: methanol,2:1,v:v) are subsequently added. The liquid is transferred to tubes for phase partition by adding 1 mL water. The lower organic phase is evaporated and used for lipid saponification and TLC separation of the free [1-¹⁴C] Stearic Acid (substrate) and [1-¹⁴C] Oleic Acid (formed product). Lipids extracted from the cells are applied to TLC plates previously immersed in 10% NO₃ Ag and activated at 120℃x60 min. Unlabeled stearic and oleic acid are added to each application point as carriers and as internal standards for identification. The plates are run with a solvent mixture of Chloroform:MeOH:AcH:DDW (90:8:1:0.8). The free fatty acids are detected by U.V. after spraying the TLC with a 2',7',dichlorofluorescein solution. The spots corresponding to stearic and oleic acid are scraped and the radioactivity counted in a sc intillating counter. SCD1 desaturase activity is calculated from the percent conversion of substrate to product and the conversion to pmol/min/10⁶ cells.

	実験の流れ	PluriSIn #1 (NSC 14613) relative cell numbers are determined by fixating the cells with 0.5% glutardialdehyde and staining with methylene blue dissolved in 0.1 M boric acid (pH 8.5). Color extraction is performed using 0.1 M hydrochloric acid, and the staining (which is proportional to cell number) is quantitated by measuring absorbance at 650 nM.
