Technical Data

Formula

C15H11F2N3
Molecular Weight 271.26 CAS No. 1262888-28-7
Solubility (25°C)* In vitro DMSO 54 mg/mL (199.07 mM)
Ethanol 7 mg/mL (25.8 mM)
Water Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
5.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 100 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.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description Spautin-1 is a potent and specific autophagy inhibitor, and inhibits the deubiquitinating activity of USP10 and USP13 with IC50 of ∼0.6-0.7 μM. Spautin-1 enhances apoptosis.
Targets
USP10 [1]
(Cell-free assay)		 USP13 [1]
(Cell-free assay)
0.5779 μM 0.6916 μM
In vitro

Spautin-1 promots the degradation of Vps34 complexes by regulating the deubiquitination activity of USP10 and USP13, and reduces the levels of PtdIns3P. [1] In PDGF-treated cells, spautin-1 stabilizes α-smooth muscle cell actin and calponin, prevents actin filament disorganization, diminishes production of extracellular matrix, and abrogates VSMC hyperproliferation and migration. [2] In CML cells, spautin-1 markedly inhibits IM-induced autophagy by downregulating Beclin-1, and enhances IM-induced apoptosis by inactivating PI3K/AKT and activating downstream GSK3β. [3] Spautin-1 also specifically reduces infectious dengue virus titers in BHK-21 cells. [4]
