General description

Chemical structure: peptide


Valinomycin is a cyclic dodecadepsipeptides with potassium ionophoric properties. It is used to study ion transport in biological systems. It is used to study its inhibitory effect on intact cells and the growth of bacteria and yeast. It is used to induce apoptosis.

Biochem/physiol Actions

Valinomycin is a K+-selective ionophoric cyclodepsipeptide. It is a potassium ionophore which uncouples oxidative phosphorylation, induces apoptosis in murine thymocytes, inhibits NGF-induced neuronal differentiation and antagonizes ET-induced vasoconstriction. It is reported to be insecticidal, nematicidal and antiviral.

Cereulide and valinomycin are highly similar cyclic dodecadepsipeptides with potassium ionophoric properties. Cereulide, produced by members of the Bacillus cereus group, is known mostly as emetic toxin, and no ecological function has been assigned. A comparative analysis of the antimicrobial

Since its discovery, the light-gated cation channel Channelrhodopsin-2 (ChR2) has proven to be a long-sought tool for the noninvasive, light-activated control of neural cells in culture and in living animals. Although ChR2 is widely used in neurobiological applications, little is

Compounds containing cyanoguanidine and 3-amino-1,2,4-benzothiadiazine-1,1-dioxide have been studied as anion receptors and transporters. Significant affinity for oxo-anions was observed in organic solution and the receptors were found to function as transmembrane chloride/nitrate antiporters with transport rates enhanced in the presence
