Valinomycin
D000890 - Anti-Infective Agents > D000900 - Anti-Bacterial Agents D049990 - Membrane Transport Modulators D007476 - Ionophores 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 several Streptomyces strains. C274 - Antineoplastic Agent > C186664 - Cytotoxic Chemotherapeutic Agent > C259 - Antineoplastic Antibiotic Valinomycin is a potassium-specific ionophore, the valinomycin-K+ complex can be incorporated into biological bilayer membranes with the hydrophobic surface of valinomycin, destroys the normal K+ gradient across the membrane, and as a result kills the cells, incorporating into liposomes can significantly reduces the cytotoxicity and enhances the targeting effect. Valinomycin exhibits antibiotic, antifungal, antiviral, antitumor and insecticidal efficacy, thus can be used for relevant research[1][2]. Valinomycin (NSC 122023), a cyclic depsipeptide antibiotic, act as a potassium selective ionophore. Valinomycin (NSC 122023) inhibits lymphocyte proliferation by its effects on the cell membrane, and induces apoptosis in CHO cells[1]. Valinomycin induces activation of PINK1 leading to Parkin Ser65 phosphorylation[2].
Candicidin
Candicidin is only found in individuals that have used or taken this drug. It is an antibiotic obtained from a streptomyces (Streptomyces griseus) and active against some fungi of the genus Candida (C. albicans). Candicidin is administered intravaginally in the treatment of vulvovaginal candidiasis.Ergosterol, the principal sterol in the fungal cytoplasmic membrane, is the target site of action of Candicidin. Candicidin binds irreversibly to ergosterol, resulting in disruption of membrane integrity and ultimately cell death. There is some evidence that the binding site in the cell wall may be to fatty acids or fatty acid esters and that this binding capacity must be satisfied before candicidin can bring about its lethal effect by binding to sterol in the cell membrane.
