AbstractA set of crown ethyl acyl derivatives based on 18-crown-6 moiety was synthesized and evaluated for biological activity. In vitro antiproliferative profiling demonstrated significant activities against HBL-100, HeLa, SW1573 and WiDr human cell lines. The most active compound exhibited GI50 values in the range of 3.7–5.6 μM. Antimicrobial evaluation showed that three polyaromatic compounds were active against Staphylococcus aureus (MIC90 values from 8.3 μM to 50 μM), whereas a (decyloxy)benzene substitution exhibited moderate activity against Candida albicans (MIC90 values 36 μM). According to SAR evaluation, the size of the crown ether and the acyl side chain had a significant effect on the bioactivity. Aromatic moieties close to the acyl group led to improved bioactivity as exemplified by some of the tested compounds. These results provide further evidence on the potential of crown ethyl structure as a scaffold for developing new biological probes and lead candidates for drug development.
