| Description | Mdivi-1 (Mitochondrial division inhibitor 1) is a mitochondrial division inhibitor that inhibits DRP1 and Dynamin I (IC50=1-10 μM). Mdivi-1 inhibits mitochondrial autophagy. |
| Targets & IC50 | POP92:15 µM, Dnm1 GTPase:1 μM-10 μM, MDA-MB-231 cells:55.93 ± 1.92 μM |
| In vitro | In the ganglion cell layer (GCL), Mdivi-1 exhibits strong immunoreactivity. Twelve hours following ischemic induction, Mdivi-1 significantly increases protein expression within the GCL. It notably reduces the expression of GFAP protein without altering Drp1 protein expression. In the normal murine retina, Mdivi-1 primarily localizes to the inner plexiform layer, ganglion cell layer, outer plexiform layer, and inner nuclear layer. Early in the development of the ischemic murine retina, there is a marked increase in the protein expression of Mdivi-1 and glial fibrillary acidic protein (GFAP). Mdivi-1 inhibits apoptosis in the ischemic retina and significantly increases the survival rate of retinal ganglion cells (RGC) two weeks post-ischemia. |
| In vivo | Mdivi-1 inhibits the ATPase activity and self-assembly of Dnm1 by inducing a conformational change (IC50<10 μM). It effectively suppresses C8-Bid and STS-induced mitochondrial outer membrane permeabilization (MOMP) in HeLa cells and extracellular mouse liver mitochondria. Mdivi-1 blocks the divisionof Dynamin-related GTPases, yeast Dnm1, and human Drp1, facilitating efficient and reversible mitochondrial fusion into a net-like structure. Intracellularly, it prevents apoptosis by inhibiting mitochondrial outer membrane permeabilization. Mdivi-1 represents a potential therapeutic class for treating stroke, myocardial infarction, and neurodegenerative diseases. |

| Kinase Assay | All GTPase assay reactions are started in a 200 μL volume, of which 150 μL is placed into the well of a 96-well plate. Depletion of NADH, as monitored by reading the A340 of the reaction, is measured every 20 s for a total of 40 min using a SpectraMAX 250 96-well plate reader. Spectrophotometric data are transferred to Excel and the measured steady state depletion of NADH over time is converted to protein activity. |
| Cell Research | Mdivi-1 is dissolved in DMSO. YPGlycerol plates are topped with 10 mL YPGlycerol containing 1% low melt agar and 75 μM mdivi-1, and cells are spotted 12 hours later using a 48 well pinning device. After pinning cells, plates are incubated at 24°C or 37°C and imaged using an Eagle Eye II imaging system. |

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, and a total of 10 animals are to be administered, using a formulation of 
10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH2O , the resulting working solution concentration would be 2 mg/mL.Dissolve 2 mg of the compound in 100 μL DMSO to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
1) Add 100 μL of the DMSO stock solution to 400 µL PEG300 and mix thoroughly until the solution becomes clear.
2) Add 50 µL Tween 80 and mix well until fully clarified.
3) Add 450 µL Saline,PBS or ddH2O and mix thoroughly until a homogeneous solution is obtained.
