The natural product dihydroferulic acid (DFA, 1) and the synthesized DFA methyl (4a), ethyl (4b), propyl (4c), hexyl (4d), octyl (4e), and decyl (4f) esters were examined for antifungal activity. Test fungi included Saccharomyces cerevisiae (wild type, and deletion mutants slt2 Delta and bck1 Delta), Aspergillus fumigatus, and A. flavus. Growth inhibition of S. cerevisiae treated with 5 mM DFA or the corresponding esters was 4a, 4b, and 4c >98%; 4d 18.8%; 1 6.4%; 4e 6.2%; and 4f 2.8%, relative to the control. The 50% minimum inhibitory concentrations for the more active propyl, methyl, and ethyl esters were 1.5, 2.1, and 4.0 mM, respectively. Compound 4c inhibited 100% growth of both aspergilli at 6.4 mM.

UI	MeSH Term	Description	Entries
D003373	Coumaric Acids	Hydroxycinnamic acid and its derivatives. Act as activators of the indoleacetic acid oxidizing system, thereby producing a decrease in the endogenous level of bound indoleacetic acid in plants.

D000935	Antifungal Agents	Substances that destroy fungi by suppressing their ability to grow or reproduce. They differ from FUNGICIDES, INDUSTRIAL because they defend against fungi present in human or animal tissues.

D012441	Saccharomyces cerevisiae	A species of the genus SACCHAROMYCES, family Saccharomycetaceae, order Saccharomycetales, known as "baker's" or "brewer's" yeast.
