Abstract Undenicylic acid (10:1) is known as an antifungal agent and an active
ingredient of many topical medicines [1–6]. The present research investigates the preparation of aliphatic esters of 10-undecylic acid with butanol and i-amyl alcohol by
the conventional and ultrasound-assisted syntheses as well as the structural elucidation of the resulting compounds, by FTIR and NMR spectroscopy. The antimicrobial
properties of the obtained 10-undecylenic esters were tested against Gram-positive
bacteria (Staphylococcus aureus; Enterococcus faecalis; Listeria monocytogenes),
Gram-negative bacteria (Escherichia coli; Salmonella sp.) and filamentous fungi
(Penicillium sp.; Aspergillus niger; Fusarium moniliforme) using the conventional
agar-well diffusion assay. The results demonstrated that… More >
