This might come from the strongest mesomeric effect, which produced from the delocalization of the unshared electrons of oxygen throw the furan ring into the [alpha], [beta]-unsaturated carbonyl system to accommodate a negative charge on the oxygen of the carbonyl group Scheme 2, which might make the compound less antibacterial active compared with other substituted [alpha], [beta]-unsaturated carbonyl compounds.
