VALINOMYCIN Usage And Synthesis

Chemical Properties

white crystalline powder

Uses

Insecticide, nematocide, Patterson, Wright, US 3520973 (1970 to Am. Cyanamid).

Uses

antibiotic; LD50 (rat, po) 4 mg/kg

Uses

K+-selective ionophoric cyclodepsipeptide; potassium ionophore which uncouples oxidative phosphorylation, induces apoptosis in murine thymocytes, inhibits NGF-induced neuronal differentiation and anta gonizes ET-induced vasoconstriction. Used as insecticide, nematocide.

Uses

Valinomycin is a hydrophobic cyclodepsipeptide with potent antitumour activity. Valinomycin is a highly selective potassium ionophore and this action leads to a diverse range of profound cell membrane effects. More recently, valinomycin has found application as a biosensor to detect to detect potassium efflux.

Definition

ChEBI: A twelve-membered cyclodepsipeptide composed of three repeating D-alpha-hydroxyisovaleryl-D-valyl-L-lactoyl-L-valyl units joined in sequence. An antibiotic found in severa Streptomyces strains.

General Description

Shiny crystalline solid. Used as an insecticide and nematocide. Not registered as a pesticide in the U.S.

Reactivity Profile

VALINOMYCIN is an amide. Amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx).

Health Hazard

VALINOMYCIN is highly toxic orally.

Fire Hazard

When heated to decomposition, VALINOMYCIN emits toxic fumes of nitrogen oxides.

Biological Activity

Selective K + ionophore (K 0.5 values are 48, 73, 75, 93 and 246 mM for K + , Rb + , Cs + , Na + and Li + respectively) that transports K + across biological and artificial lipid membranes. Inhibits Ca 2+ -ATPase activity and induces apoptosis through mitochondrial membrane depolarization, caspase-3 activation and phosphatidylserine translocation in vitro .

Purification Methods

Recrystallise valinomycin from dibutyl ether or Et2O. It is dimorphic: modification A crystallises from n-octane, and modification B crystallises from EtOH/H2O. It is soluble in pet ether, CHCl3, AcOH, BuOAc and Me2CO. [Smith et al.
