Abstract

Aim: To evaluate the action of promethazine, fluoxetine and carbonyl cyanide 3-chlorophenylhydrazone as efflux pump inhibitors (EPIs) against multidrug-resistant Pseudomonas aeruginosa. Methods: The effect of the compounds was evaluated in planktonic cells and bacterial biofilms. Accumulation tests were performed with ethidium bromide to prove their action as EPIs. Then, they were associated with antimicrobials. Results: Effect on planktonic cells and biofilms was found. Assays with ethidium bromide indicate their action as EPIs. Significant reductions in the metabolic activity of biofilms were observed after the association with the antimicrobials, especially for meropenem. Conclusion: It is possible to prove the action of these compounds as EPIs for P. aeruginosa and demonstrate the relevance of efflux pumps in antimicrobial resistance.

将已获批准的药物作为潜在的外排泵抑制剂重新用于耐多药铜绿假单胞菌。

目的：评估丙咪嗪、氟西汀和 3-氯苯基腙作为外排泵抑制剂（EPIs）对耐多药铜绿假单胞菌的作用。方法：在浮游细胞和细菌生物膜中评估了这些化合物的效果。用溴化乙锭进行了蓄积试验，以证明其作为 EPIs 的作用。然后，将这些化合物与抗菌剂结合起来。结果发现它们对浮游细胞和生物膜都有影响。用溴化乙锭进行的检测表明它们具有 EPIs 的作用。生物膜与抗菌素（尤其是美罗培南）结合后，其代谢活性显著降低。结论可以证明这些化合物对铜绿假单胞菌具有 EPI 作用，并证明了外排泵与抗菌药耐药性的相关性。
