Tetradecyltrimethylammonium bromide

Description

MiTMAB (1119-97-7) is a dynamin I/II inhibitor targeting the dynamin-phospholipid interaction and inhibiting dynamin GTPase activity with a Ki=940nM.1 Rapidly and reversibly inhibits multiple forms of endocytosis with no acute cellular damage1. A useful pharmacological tool for studying dynamin-mediated trafficking events.2 Induces cytokinesis failure and apoptosis in human cancer cells.3 Induces cytoprotective autophagy in human Jurkat T cells.4

The Uses of Tetradecyltrimethylammonium bromide

Disinfectant; deodorant; laboratory reagent.

The Uses of Tetradecyltrimethylammonium bromide

Myristyltrimethylammonium has been used in a study to assess a surfactant-controlled synthetic method to obtain a nanophase of mesoporous ceria-zirconia solid solution containing cationic defects in the crystalline structure.??It has also been used in a study to determine the low molecular weight of organic acids in soils and plants by capillary zone electrophoresis.

Definition

Myristyltrimethylammonium bro-mide.

General Description

Myristyltrimethylammonium bromide is a cationic/zwitterionic type of surfactant.

Purification Methods

Crystallise the bromide from acetone or a mixture of Me2CO and >5% MeOH or Me2CO/EtOH. Wash it with diethyl ether and dry it in a vacuum oven at 60o. It is a cationic detergent. Its solubility is 1g/5g H2O. [Dearden & Wooley J Phys Chem 91 2404 1987, Shelton et al. J Am Chem Soc 68 754 1946, Beilstein 4 III 419, 4 IV 813.]
