描述

一般說明

Chemical structure: peptide

Valinomycin is a neutral cyclic dodecadepsi-peptide antibiotic, that has a 36-member ring.Valinomycin consists of twelve stereogenic centers that are made of three repeating sequences of a tetramer of D-α-hydroxyisovalericacid-D-valine-L-lactate-L-valine. It shows antibacterial, antitumor, antifungal, antiviral, and insecticidal properties. Valinomycin exerts its antiviral activity against human coronavirus OC43 (HCoV-OC43), severe acute respiratory syndrome coronavirus (SARS-CoV), and middle-east respiratory syndrome coronavirus (MERS-CoV).

應用

Valinomycin has been used as an internal standard in the cytotoxicity assay for the detection of cereulide produced by emetic Bacillus cereus. It has also been used in the measurement of the electrogenicity of bile salt/H⁺ antiport in Escherichia coli.
