Novel antimicrobial compositions and strategy to combat bacterial resistance in a variety of bacterial strains are disclosed. The antimicrobial compositions comprise a combination of mitomycin C, or other reductively activated compounds, and ABPI and/or imino-ABPI. The unique strategy involves exposing microorganisms to a first antimicrobial agent, such as mitomycin C, which can induce the expression of at least one protein which confers resistance to mitomycin C, i.e., inactivates mitomycin C. Simultaneously or soon thereafter, the microorganisms are exposed to a second antimicrobial agent, such as ABPI and/or imino-APBI, which is activated by the same protein which inactivates the first antimicrobial agent.
本研究公开了新型抗菌组合物和对抗各种细菌菌株耐药性的策略。抗菌组合物包括丝裂霉素 C 或其他还原活化化合物与 ABPI 和/或亚氨基 ABPI 的组合。这种独特的策略包括将微生物暴露于第一种抗菌剂,如丝裂霉素 C,丝裂霉素 C 可诱导至少一种蛋白质的表达,这种蛋白质可赋予微生物对丝裂霉素 C 的抗性,即使丝裂霉素 C 失活;同时或随后不久,微生物暴露于第二种抗菌剂,如 ABPI 和/或亚胺-APBI,ABPI 和/或亚胺-APBI 被使第一种抗菌剂失活的相同蛋白质激活。
