In vitro inhibition of bacterial DNA gyrase by cinodine, a glycocinnamoylspermidine antibiotic.

abstract：:Antimicrobial peptides (AMPs) are effective antibiotic agents commonly found in plants, animals, and microorganisms, and they have been suggested as the future of antimicrobial chemotherapies. It is vital to understand the molecular details that define the mechanism of action of resistance to AMPs for a rational plann...
