In a wide search program towards new and efficient biological active agents, a series of chalcone and flavone derivatives holding allylic substitutions have been synthesized and tested for their in vitro antibacterial and antifungal activities. The synthesized compounds were tested in vitro against Gram-positive, Gram-negative bacteria, and the yeast Candidia kefir in comparison with control drugs (Sulfamethoxazole and Fluconazole). The antioxidant activity of the synthesized allylic chalcones and flavones was also assessed using two methods, including, 1,1-biphenyl-2-picrylhydrazyl (DPPH) radical scavenging, and reducing power assays and compared to reference drug Trolox.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
