Description

General description

Chemical structure: peptide

Valinomycin is a cyclic peptide, which contains d-valine, d-α-hydroxyvaleric acid, l-valine, and l-lactic acid in the sequential order of cyclo-[(l-Val-d-Hyv-d-Val-l-Lac)₃].

Valinomycin, a nonribosomal peptide (NRP), is proposed to have a structure of a 24-membered cyclic peptide cyclo-(d-α-hydroxyisovaleryl-d-valyl-l-lactyl-l-valyl)2. It exhibits antitumor properties and plays a major role as a mitophagy activator. Initially isolated as an antibiotic compound, valinomycin has demonstrated antibacterial activity against Mycobacterium tuberculosis. Moreover, it has been identified as a potent antiviral agent against a wide spectrum of viruses, including human coronavirus, bunyavirus, enterovirus, and flavivirus.

Application

Valinomycin has been used:

• to equilibrate intracellular pH and extracellular pH of 5 (and 6-)-carboxyfluorescein succinimidyl ester (cFSE) in Escherichia coli strain B23
• as an ionophore to equilibrate intracellular pH and extracellular pH of lactic acid bacteria (LAB) strains
• to establish the desired pH for acid-base transition and formation of K⁺-valinomycin diffusion potential

Biochem/physiol Actions

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

Valinomycin selectively transfers alkali metal ions via biological and synthetic membranes. The formation of a metal ion-peptide complex contributes to this ion-transporting. Valinomycin can create stable complexes with potassium, rubidium, and cesium (K⁺, Rb⁺, and Cs⁺) .
