Taking the 1 mL working solution as an example, add 50 μL of 80 mg/ml clarified DMSO stock solution to 300 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 600 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	Dynasore is a cell-permeable, reversible non-competitive dynamin inhibitor of GTPase activity of dynamin 1/2, with IC50 of 15 μM in a cell-free assay, also inhibits the mitochondrial dynamin Drp1, with no effect against other small GTPase. Dynasore suppresses mTORC1 activity and induces autophagy. Dynasore inhibits the entry of several viruses, including herpes simplex virus (HSV).
in vitro	Dynasore acts as a potent inhibitor of endocytic pathways known to depend on dynamin by rapidly blocking coated vesicle formation within seconds of dynasore addition. Two types of coated pit intermediates accumulate during dynasore treatment, U-shaped, half formed pits and O-shaped, fully formed pits, captured while pinching off. Dynasore at concentration of 80 μM, also inhibits the enzymatic activity of the mitochondrial dynamin Drp1. Dynasore strongly blocks the uptake, trafficking, and intracellular accumulation of transferrin in HeLa cells with IC50 of ~15 μM. Dynasore also prevents the endocytosis of low-density lipoprotein and cholera toxin. Dynasore (80 μM) strongly interferes with the spread of freshly plated cells, and inhibits BSC1 cells migration by about 50%. ^[1] Dynasore completely and reversibly blocks endocytosis in cultured hippocampal neurons after sustained or brief action potentials stimuli with full inhibition at 80 μM and a half-maximal inhibition at ~30 μM. In the presence of Dynasore, low-frequency stimulation leads to sustained accumulation of synaptopHluorin and other vesicular proteins on the surface membrane at a rate predicted from net exocytosis, as well as a reduction in the density of synaptic vesicles and the presence of endocytic structures only at synapses. ^[2] Dynasore can block human epithelial cell HEK 293 infection of human papillomavirus type 16 and bovine papillomavirus type 1 pseudovirions with equal IC50 of ~80 μM, which is partly reversible. ^[3]

キナーゼアッセイ	GTPase activity assay
キナーゼアッセイ	GTPase activity is measured by using a radioactive charcoal-based assay. Proteins dynamin, human Drp1 at the indicated concentrations are incubated in 10 mM Tris (pH 7.2), 2 mM MgCl₂, and 20 μM GTPγP³² (2000 dpm/pmol) alone or, when appropriate, with lipid nanotubes for the indicated times and temperatures; the final NaCl concentration is 150 mM NaCl for the high-salt condition and between 10 and 20 mM for the low-salt conditions depending on the protein concentration in the stock solution. GTP hydrolysis is ended by transferring 10 μL aliquots of the reaction into a 500 μL slurry containing acid-washed charcoal, followed by a 10 min centrifugation (20000 × g, 4 ℃) and final counting of the liberated P³²O₄ contained in 250 μL supernatant.
