标 题 :Nonanol/nonene antimicrobial compositions
发明人：BURKE BASIL A; NAIR MURALEEDHARAN
权利人:PCRI INC
摘要:Substituted 5'-nonanol/5'-nonene compounds which exhibit important antimicrobial and antifungal activity, compositions and methods of delivery against pathovars and pathogens, and methods of synthesis from commonly available reactants. The antimicrobial composition active ingredient is one or more substituted 1,2-alkylidenedioxybenzene compounds of the formula: where R3 is selected from 5'-nonanol and 5'-nonene, and R1 and R2 are selected from H and C1-C5 alkyl, alkenyl and alkynyl groups. The preferred compounds are 5-(5'-hydroxy- 5'- nonanyl)-1,1-methylenedioxybenzene and 4-(5'-non-4'-enyl)-1,2-methylenedioxybenzene. Compositions including these compounds exhibit antimicrobial activity against a variety of pathogens and pathovars, e.g., Xanthomonas campestris spp. bacteria, antifungal activity against a variety of fungi and bacteria, and are highly specific, e.g., having antifungal activity against wheat powdery mildew and cucumber downy mildew, but do not affect seed germination or have appreciable herbicidal or insecticidal activity. Methods and compositions for delivery of these agents against such pathogens, and methods of chemical synthesis of the compounds are disclosed.
