0.4mg/ml

Taking the 1 mL working solution as an example, add 50 μL of 8 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to make it clear; then continue to add 500 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	BPTES is a potent and selective Glutaminase GLS1 (KGA) inhibitor with IC50 of 0.16 μM. It has no effect on glutamate dehydrogenase activity and causes only a very slight inhibition of γ-glutamyl transpeptidase activity.
in vitro	BPTES inhibits glutaminase activity expressed in human kidney cells with IC50 of 0.18 μM, and inhibits glutamate efflux by microglia with IC50 of 80-120 nM. ^[1] BPTES preferentially slows cell growth in D54 cells with mutant IDH1. BPTES also inhibits glutaminase activity, lowers glutamate and α-KG levels, and increases glycolytic intermediates. ^[2] BPTES (10 μM) inhibits cell growth of mHCC 3–4 cells derived from LAP/MYC tumors. BPTES also inhibits growth of a MYC-dependent P493 cells by blocking DNA replication, leading to cell death and fragmentation. ^[3]
in vivo	In LAP/MYC mice, BPTES (12.5 mg/kg, i.p.) prolongs survival with no significant effects on MYC, GLS, or GLS2 levels. BPTES (200 μg/mouse, i.p.) also inhibits tumor cell growth in mice harboring P493 tumor xenografts. ^[3]

キナーゼアッセイ	Glutaminase Inhibition: Cell Free Assay
キナーゼアッセイ	Assay plates are prepared containing 2 μL test compound in DMSO/well. The enzyme is diluted to 1 unit (liver) or 0.8 unit (kidney)/100 μL in glutaminase assay buffer, and 100 μL diluted enzyme is added to each well of the assay plate by Multidrop. The contents are mixed by shaking at full speed for 1 min on TiterMix 100. The plates are preincubated at room temperature (RT) for 20 min to allow binding of test compounds to glutaminase, and 50 μL glutamine solution (7 mM in assay buffer) is added to each well by Multidrop. The contents are shaken at full speed for 30 sec on TiterMix 100, and the plates are then incubated at RT for 60 min (liver) or 90 min (kidney). To stop the reactions, 20 μL HCl (0.3 N) is added to each well by Multidrop and mixed immediately by shaking for 30 sec on TiterMix 100. For quantification, glutamate (formed by glutaminase-catalyzed hydrolysis of glutamine) is oxidized to 2-oxoglutarate by a second enzyme, glutamate dehydrogenase (GDH), with the concomitant production of the reduced form of nicotinamide adenine dinucleotide (NADH). Reduction of nitro blue tetrazolium (NBT) in the assay solution by NADH, catalyzed by phenazine methosulphate (PMS), results in the formation of a blue-purple formazan. The absorption of formazan at 540 nm is linearly proportional to the concentration of glutamate up to 200 μM. NBT/GDH reagent (50 μL) is added to each well by Multidrop and mixed by shaking for 30 sec on TiterMix 100, and the plates are incubated at RT for 20 min to allow color formation by the GDH reaction. Glutamate concentration is determined from formazan concentration as determined by reading OD540 nm on a SpectraMax 340.

	実験の流れ	Cell growth assays are carried out using alamarBlue. Cells are plated at a density of 500 cells/well in a 96-well black clear bottom plate. At 24 hrs, media is changed to the appropriate media (DMEM with 4.5 g/L, 1.5 g/L or 0.1 g/L glucose, 10% FBS, pencillin/streptomycin, and 4 mM glutamine with or without doxycyline. 48 hours after plating, compounds or DMSO are added. Media and alamarBlue is added to a volume of 200 礚 in each well. Fluorescence is measured at 48 hrs (AOA, BPTES) using a Victor3 plate-reader.
