INTRODUCTION: Chalcone compounds exhibit diverse bioactivities, attracting significant interest. Morpholine is a heterocycle commonly used in medicinal chemistry. It could enhance the potency, pharmacokinetics, and bioactivities of its compounds.
METHODS: Adding morpholine into the chalcone scaffold could help create new compounds with favorable bioactivities. In this study, a new parallel synthesis procedure has been developed. Using this procedure, 18 novel morpholinoalkoxychalcones have been successfully synthesized. They had chains with morpholine appended on ring A or ring B. All the synthesized compounds were evaluated for the antibacterial and antifungal activities by agar diffusion method on 5 bacteria and 2 fungi strains.
RESULTS: The compounds with good inhibition were determined with respect to the MIC values by the agar dilution method. Among the tested compounds, B.21 was found to be the best against E. faecalis, with an MIC value of 0.6 mM. B.43 with an MIC value of 2.04 mM has displayed its potential in inhibiting A. niger and C. albicans the best among other compounds.
CONCLUSION: The in silico study has revealed two targets to align with the in vitro results. Longer alkyl chains have enhanced the activity, along with the presence of OH, NH2, and halogen groups on both rings A and B.
