Biological Activity

Description Mdivi-1 is a selective cell-permeable inhibitor of mitochondrial division DRP1 (dynamin-related GTPase) and mitochondrial division Dynamin I (Dnm1) with IC50 of 1-10 μM.
Features The first selective inhibitor of mitochondrial division dynamins.
Dynamin1 [1]
1 μM-10 μM
In vitro

Mdivi-1 is a cell-permeable quinazolinone compound that inhibits yeast (Dnm1) and mammalian (Drp1) division DRPs (dynamin-related GTPases) and effectively induces mitochondrial fusion into net-like structures in a reversible manner. Cell-free studies indicate that mdivi-1 blocks Dnm1 ATPase activity (IC50<10 μM) and self-assembly by an allosteric modulation-based mechanism. Mdivi-1 is shown to effectively suppress STS- as well as C8-Bid-induced MOMP (Mitochondrial Outer Membrane Permeabilization) in HeLa cultures and in cell-free murine liver mitochondria preparations, respectively, as assessed by cytochrome C release. In cells, mdivi-1 retards apoptosis by inhibiting mitochondrial outer membrane permeabilization. In principle, mivi-1 represents a class of therapeutics for stroke, myocardial infarction, and neurodegenerative diseases. [1]

In vivo Drp1 and GFAP protein expression is significantly increased in the early neurodegenerative events of ischemic mouse retina. Mdivi-1 treatment blocks apoptotic cell death in ischemic retina, and significantly increases RGC survival at 2 weeks after ischemia. In the normal mouse retina, Drp1 is expressed in the ganglion cell layer (GCL) as well as the inner plexiform layer, the inner nuclear layer (INL), and the outer plexiform layer (OPL). In the GCL, Drp1 immunoreactivity is strong in RGCs. While Drp1 protein expression is increased in the GCL of vehicle-treated ischemic retina at 12 hours. Mdivi-1 treatment does not change this increase of Drp1 protein expression but significantly decreased GFAP protein expression. [2]

Bio Calculators

Molarity Calculator

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
