Naturally occurring diallyldihydroxybiphenyl compounds, magnolol and honokiol were reported to have potent antibacterial activities against most of Gram positive bacteria (1-4). To developmore potent antibacterial agents, some allyhydroxybiphenyl derivatives were synthesized from the starting compounds, p-phenyl-phenol (I) p-phenylphenol (IV), o, o-biphenol (VII) and p. p'-biphenol (XII). Among the newly synthesized compounds (III, VI, IX, XI, XIV and XVI), the antibacterial activities of 2-allyl-p-phenylphenol (VI), 6-ally-o, 0'-biphenol (IX), 2, 2'-diallyl-o, o'-biphenol (XIV) and 2, 2', 6-triallyl-p, p'-biphenol (XIV) were more potent than those of magnolol and bonokiol against a cariogenic bacterium, Stroptococcus matans ATCC OMZ 176.
