We reported the synthesis, antifungal evaluation and study on substituent effects of 21 chalcones. A lot of genetically defined strains belonging to different yeast genera and species, namely Saccharomyces cerevisiae, Hansenula polymorpha and Kluyveromyces lactis, were used as test organisms. Concerning the mode of the antifungal action of chalcones it was shown that DNA was probably not the main target for the chalcones. It was revealed that the yeast's intracellular glutathione and cysteine molecules play significant role as defence barrier against the chalcone action. It was also shown that chalcones may react with some proteins involved in cell separation.

A large series of chalcones were synthesized and studied for activity against Candida albicans. The SAR analysis showed that the antifungal activity was highly dependent on the substitution pattern of the aryl rings and correlated to a large extent with the ability of compounds to interact with sulfhydryl groups. The most active were the hydroxylated chalcones as their activity related to the location of the phenolic group in the aryl ring B as follows: o-OH > p-OH ～ 3,4-di-OH > m-OH. These and other correlations obtained strongly contribute to the knowledge for design of anticandidal chalcones.
