Novel bis cyclohexenone ester derivatives 14-19 were synthesized and characterized by their spectral data. In vitro microbiological evaluations were carried out for all the novel compounds 14-19 against clinically isolated bacterial and fungal strains. Compounds 15, 16, 18 against Staphylococcus aureus, 14, 15 against beta-Haemolytic streptococcus, 15, 19 against Micrococcus luteus, 17, 18 against Salmonella typhii, 14, 17 against Shigella flexneri, 15 against Escherichia coli, 16 against Pseudomonas aeruginosa, 15, 18, 19 against Klebsiella pneumonia exhibited potent antibacterial activity at an minimum inhibitory concentration (MIC) value of 6.25 mu g/ml, whereas compound 16 against Aspergillus flavus, 17 against A. niger, 16, 18 against Mucor indicus, 15, 17-19 against Microsporum gypseum revealed excellent antifungal activity at an MIC value of 6.25 mu g/ml.
