The development of resistance against most of the available antibiotics has made Acinetobacter baumannii(A. baumannii) a pathogen of high risk. In this study, thirty novel berberine derivatives are rationally designed, synthesized, and evaluated for their synergistic antibacterial activities against A. *** them, compound 2d shows the most potent synergetic effect to aztreonam against A. baumannii,including carbapenem-resistant and extended-spectrum β-lactamases-producing strains. Moreover, synergistic effects were observed for the combinations of 2d and different antibacterial used in clinical practices, indicating its potent broad-spectrum antibiotic-sensitizing effects against A. baumannii. The combination of 2d and aztreonam significantly improves the survival rates of G. mellonella larvae compared with aztreonam treatment alone. Mechanism studies indicate that 2d inhibits the drug efflux and iron acquisition of the bacteria by targeting the AdeB transporter protein, thus achieving a synergistic antimicrobial efficacy with different antibacterial agents. Therefore, berberine derivatives represent a new family of antimicrobial adjuvants against A. baumannii, with the advantage of dual-function antibacterial effect,and are worthy of further investigation.

Objective This study aimed to compare the current Essen rabies post-exposure immunization schedule(0-3-7-14-28)in China and the simple 4-dose schedule(0-3-7-14)newly recommended by the World Health Organization in terms of their safety,efficacy,and *** Mice were vaccinated according to different immunization schedules,and blood was collected for detection of rabies virus neutralizing antibodies(RVNAs)on days 14,21,28,35,and 120after the first ***,different groups of mice were injected with lethal doses of the CVS-11 virus on day 0,subjected to different rabies immunization schedules,and assessed for morbidity and death *** a clinical trial,185 rabies-exposed individuals were selected for post-exposure vaccination according to the Essen schedule,and blood was collected for RVNAs detection on days 28and 42 after the first *** A statistically significant difference in RVNAs between mice in the Essen and 0-3-7-14 schedule groups was observed on the 35th day(P0.05)in RVNAs levels at any time *** post-exposure immune protective test showed that the survival rate of mice in the control group was 20%,whereas that in the immunization groups was 40%.In the clinical trial,the RVNAs positive conversion rates on days 28(14 days after 4 doses)and 42(14 days after 5 doses)were both 100%,and no significant difference in RVNAs levels was observed(P>0.05).Conclusion The simple 4-dose schedule can produce sufficient RVNAs levels,with no significant effect of a delayed fourth vaccine dose(14–28 d)on the immunization potential.
