Abstract: The present disclosure discloses use of incyclinide synergized with colistin in preparation of a bactericidal drug for an Enterobacteriaceae bacterium carrying an mcr gene. Incyclinide (Ini) is a chemically modified tetracycline derivative. The present disclosure demonstrates that Ini can restore the bactericidal effect of colistin against the Enterobacteriaceae bacterium carrying the mcr gene in vitro and in animal models. Mechanism analysis shows that Ini restores the pharmaceutical effect of colistin by inhibiting lipid A modification, inducing oxidative damage, and dissipating proton motive forces (PMF). Ini, as a colistin adjuvant, has great potential in combating the Enterobacteriaceae bacterium carrying the mcr gene.
