Antifungal Activities of trans-Cinnamaldehyde Derivatives

Antifungal activities of trans-cinnamaldehyde (CA) derivatives including commercial CA derivatives as well as synthesized CA derivatives against various human pathogenic fungi were investigated. Among the derivatives tested, α- chlorocinnamaldehyde, α-bromocinnamaldehyde and α-phenyl-2,4,6-heptatrienal were more potent than CA in antifungal activity α-Bromocinnamaldehyde was the most effective in inhibiting the growth of representative fungi of dermatomycosis with minimum inhibitory cocentration (MIC) of 0.61∼9.76μg/ml. In the structure-activity relationship, introduction of the chlorine and bromine group into the C-2 of CA resulted in the decrease of MIC. Derivative with more double bands exhibited the increase of antifungal activity against various pathogenic fungi.
