Abstract

species have become resistant to commonly used anti-fungal drugs like fluconazole and echinocandins. In our screen, a series of quaternary ammonium compounds (QACs) emerged as an alternative treatment choice for drug-resistant infections.

Medium alkyl chain cationic lipo-oxazoles comprising six to thirteen twin carbon chains and a quaternary ammonium unit were synthesized and evaluated for their anti- and biofilm inhibition activity. SEM was performed to visualize membrane distortion.

Heptyl and octyl chain analogues (5c, 6b and 6c) showed promising anti-fungal activity. Compound 5c was active against both fluconazole-sensitive and resistant clinical isolates of as well as non- strains. 5c also inhibited the adhesion of cells to a polystyrene surface and restricted biofilm formation. SEM further confirmed cell membrane distortion by 5c.

A novel class of QACs, called cationic lipo-oxazoles, was tested and found to exhibit anti-fungal activity against planktonic cells as well as biofilms of .
