Antimicrobial resistance arises due to several adaptation mechanisms, being the overexpression of efflux pumps (EPs) one of the most worrisome. In bacteria, EPs can also play important roles in virulence, quorum-sensing (QS) and biofilm formation. To identify new potential antimicrobial adjuvants, a library of diarylpentanoids I [X = CH2CH2, CH2CH2CH2, CH2OCH2, CH2SCH2; R = 2-BrC6H4, 3-MeOC6H4, 4-F3CC6H4, 2,3-(MeO)2C6H3, etc.] and chalcones II [X = CH2, CH2CH2, SCH2; R = 2-MeOC6H4, 2,4,5-(MeO)3C6H2] was synthesized and tested. These compounds presented encouraging results in potentiating the activity of antimicrobials, with diarylpentanoid I [X = CH2OCH2; R = 2,3-(MeO)2C6H3] being the most promising. The compounds I [X = CH2OCH2; R = 4-BrC6H4, 2,3-(MeO)2C6H3, 3,4-(MeO)2C6H4], I (X = CH2CH2CH2; R = 2-MeOC6H4), II (X = CH2CH2; R = 2-MeOC6H4) and II [X = SCH2; R = 2,4,5-(MeO)3C6H2] displayed EP inhibitory effect, mainly in Staphylococcus aureus 272123. Compounds I [X = CH2OCH2; 2,3-(MeO)2C6H3], I (X = CH2CH2CH2; R = 2-MeOC6H4), II (X = CH2CH2; R = 2-MeOC6H4) and II [X = SCH2; R = 2,4,5-(MeO)3C6H2] exhibited inhibitory effect on biofilm formation in S. aureus 272,123 while I [X = CH2OCH2; R = 2,3-(MeO)2C6H3] and II (X = CH2CH2; R = 2-MeOC6H4) inhibited QS in the pair Sphingomonas paucimobilis Ezf 10-17 and Chromobacterium violaceum CV026. The overall results demonstrated that diarylpentanoid I [X = CH2OCH2; R = 2,3-(MeO)2C6H3] and chalcone II (X = CH2CH2; R = 2-MeOC6H4) were active against all the resistance mechanisms tested, suggesting their potential as antimicrobial adjuvants.
