Objective: The principal objective of the study was to synthesize and evaluate the biological activities of a novel class of 5-benzylidene substituted rhodanine derivatives as antimicrobial agents.Methods: All the synthesized compounds (D1-D10) were screened for their antimicrobial activities using microdilution methods as per the reported procedure.All compounds were evaluated as potential antimicrobial agents against gram-positive bacteria: Bacillus cereus, Staphylococcus aureus, gram negative bacteria: Escherichia coli Pseudomonas aeruginosa and Klebsiella pneumoniae Fungal cultures used in the study were Aspergillus niger, Candida albicans, Candida parapsilosis, Candida tropicalis and Candida glabrata.Results: Compound D6 showed good antifungal activity in the MIC range 16μg/mlagainst Candida tropicalisand Compound D10 showed good antifungal activity in the MIC range 16μg/mlagainst Candida glabrata. Compounds D2 and D5 showed good antibacterial activity at 32μg/ml. all the other compounds showed moderate antibacterial activity. Conclusion: Based on the above results, it can be concluded that the compounds may leadto the development of more potent antimicrobial drug candidates in the near future.
