The relationship between the chemical structure and antibacterial activity of alkoxyacetophenone amidinohydrazones was studied. m- or p-Alkoxy compounds showed maximum antibacterial activities with carbon atoms in the alkoxy group, and o-alkoxy compounds with 8-10 carbon atoms. Substitution of -NH2 with -[chemical formula], -[chemical formula] or -[chemical formula] in amidino moiety generally lowered the activity. Antibacterial potency of these compounds against gram-positive bacteria (G+), gram-negative bacteria (G-), and fungi. (F) decreased in this order but compounds having -[chemical formula] or -[chemical formula] at amidino moiety showed the order of G+>F>G-.
