  • Patent number: 8906915
    Abstract: The invention relates to substituted 2-aminoimidazoles and their imidazo[1,2-a]pyrimidinium salts precursors being active against biofilm formation. The invention also relates to imidazo[1,2-a]pyrimidinium salts bearing an azidoalkyl substituent, and to substituted 2-aminoimidazoles wherein the amino group bears a terminal heterocyclic group such as a triazolyl group which are formed through azide-alkyne Huisgen cycloaddition starting from said imidazo[1,2-a]pyrimidinium salts bearing an azidoalkyl substituent. The invention also relates to a class of N-(azidoalkyl)pyrimidin-2-amines useful as starting materials for the synthesis of said imidazo[1,2-a]pyrimidinium salts bearing an azidoalkyl substituent. The invention also relates to antimicrobial compositions that include a microbial biofilm formation inhibiting amount of such substituted 2-aminoimidazoles or imidazo[1,2-a]pyrimidinium salts in combination with excipients.

  • Patent number: 6521590
    Abstract: Biocidal proteins capable of isolation from seeds have been characterized. The proteins have an amino acid sequence containing the common cysteine/glycine domain of Chitin-binding Plant Proteins but show substantially better activity against pathogenic fungi, a higher ratio of basic amino acids to acidic amino acids, and/or antifungal activity which results in increased hyphal branching. Antimicrobial proteins isolated from Amaranthus, Capsicum, Briza and related species are provided. The proteins show a wide range of antifungal activity and are active against Gram-positive bacteria. DNA encoding the proteins may be isolated and incorporated into vectors. Plants may be transformed with this DNA. The proteins find agricultural or pharmaceutical application as antifungal or antibacterial agents. Transgenic plants expressing the protein will show increased disease resistance.

  • Patent number: 6492176
    Abstract: The present invention relates to a new mutant Rhizobium etli CNPAF 512 strain, having an inactivated raiI gene. Inactivation of the raiI gene leads to increased nodule number in beans upon inoculation thereof with the mutant strain. Based on this specific strain other strains can be mutated in the similar gene(s) in order to enable nodule increase and nitrogen fixation in other Leguminosae species.

  • Publication number: 20010014732
    Abstract: Biocidal proteins isolated from seeds have been characterized, in particular proteins isolated from members of the Brassicaceae, Compositae and Leguminosae families including Raphanus, Brassica, Sinapis, Arabidopsis, Dahlia, Cnicus, Lathyrus and Clitoria. The proteins show a wide range of antifungal activity and some are active against Gram-positive bacteria. All share a common amino acid sequence. DNA encoding the proteins has been isolated and incorporated into vectors. Plants transformed with this DNA may be produced. The proteins find commercial application as antifungal or antibacterial agents; transformed plants will show increased disease-resistance.
