Insights into biological activity of ureidoamides with primaquine and amino acid moieties
Primaquine (PQ) ureidoamides 5a–f were screened for antimicrobial, biofilm eradication and antioxidative activities. Susceptibility of the tested microbial species towards tested compounds showed species- and compound-dependent activity. N-(diphenylmethyl)-2-[({; ; ; 4-[(6-methoxyquinolin-8-yl)amino]pentyl}; ; ; carbamoyl)amino]-4-methylpentanamide (5a) and 2-(4-chlorophenyl)-N-(diphenylmethyl)-2-[({; ; ; 4-[(6-methoxyquinolin-8-yl)amino]pentyl}; ; ; carbamoyl)amino]acetamide (5d) showed antibacterial activity against S. aureus strains (MIC = 6.5 µg/ml). Further, compounds 5c and 5d had weak antibacterial activity against Escherichia coli and Pseudomonas aeruginosa. None of the tested compounds showed a wide spectrum of antifungal activity. In contrast, most of the compounds exerted strong activity in a biofilm eradication assay against E. coli, P. aeruginosa and Candida albicans, comparable to or even higher than gentamycin, amphotericin B or parent PQ. The most active compounds were 5a and 5b. Tested compounds were inactive against biofilm formation by C. parapsylosis, Enterococcus faecalis, C. tropicalis and C. krusei. Compounds 5b–f significantly inhibited lipid peroxidation (80–99%), whereas compound 5c presented interesting LOX inhibition.
