Chalcones are synthesized by conventional and microwave assisted synthesis methods. By microwave assisted synthesis, a considerable increase in the reaction rate has been observed and that too, with better yields. We have reported the synthesis and antifungal activity study on substituent effects of 5 chalcones. A lot of genetically defined strains belonging to different yeast genera and species, namely Aspergillus niger and Candida albicans, were used as test organisms. Inhibition of chitin biosynthesis was responsible for fungistatic activity, while the fungicidal effect was a consequence of disturbance of β (1→3) glucan synthase function. The chalcone derivatives may be a useful lead compound for the development of novel antifungal agents.
