Dynasore Structural

What is Dynasore?

Description

Dynasore (304448-55-3) is a noncompetitive inhibitor of dynamin GTPase activity and blocks dynamin-dependent endocytosis in cells, including neurons. It inhibits the GTPase activity of dynamin1, dynamin2, and Drp1 (mitochondrial dynamin). It is cell permeable, fast acting (seconds) and reversible.1,2 Dynasore is a extremely useful tool for studying endocytosis and other cellular events which are dependent on dynamin.3-5

The Uses of Dynasore

Dynasore is a cell-permeable, reversible inhibitor of dynamin 1, dynamin 2, and mitochondrial dynamin, Drp1 GTPase activity (IC50 = 15 μM). Through this action, dynasore inhibits clathrin-dependent vesicle formation and endocytosis, which is necessary for internalization of certain parasites and viruses, as well as particles and receptor ligands. In some cases, dynasore can also augment the release of neurotransmitters and secreted cytokines.[Cayman Chemical]

The Uses of Dynasore

Dynamin Inhibitor I, Dynasore is an inhibitor of Dynamin I and Dynamin II.

Definition

ChEBI: A carbohydrazide resulting from the formal condensation of the hydrazone moiety of 3,4-dihydroxybenzaldehyde hydrazone with the carboxy group of 3-hydroxy-2-naphthoic acid. It is a cell-permeable, reversible noncompetitive inhibitor of the GTPase activity f dynamin 1 and 2 and Drp1 (mitochondrial), while exhibiting no significant effect against two other small GTPases, MxA and Cdc42.

What are the applications of Application

Dynamin Inhibitor I, Dynasore is a non-competitive, cell-permeable semicarbazone compound inhibitor of Dynamin I and Dynamin II.

What are the applications of Application

Dynasore monohydrate is a reversible noncompetitive dynamin 1 and 2 GTPase activity inhibitor

Biological Activity

Non-competitive inhibitor of dynamin 1, dynamin 2 and mitochondrial dynamin (Drp1) GTPase activity. Does not inhibit other small GTPases. Blocks endocytic pathways dependent on dynamin and inhibits cell spreading and migration of BSC1 cells.
