  • Patent number: 9616116
    Abstract: The present invention provides an immunogenic composition of a lipopolysaccharide vaccine and a non-alum adjuvant. The immunogenic composition may be detoxified J5 core lipopolysaccharide of Escherichia coli non-covalently complexed with group B meningococcal outermembrane protein. Also provided are methods for preventing an infection caused by a Gram-negative bacteria in an individual via administering the immunogenic compositions to the individual.
    Type: Grant

  • Patent number: 7897162
    Abstract: Disclosed herein is a pharmacophore model for arthropod repellent activity and methods of making and using thereof. The pharmacophore comprises two hydrophobic aliphatic functions, one aromatic function and one hydrogen bond acceptor function. The pharmacophore model was made using a test set of arthropod repellent compounds. Also disclosed are arthropod repellent compounds identified by screening databases with the pharmacophore model. Also disclosed are methods of repelling arthropods from a surface or area. Compositions and formulations comprising the compounds of the present invention as well as objects having the compounds of the present invention are disclosed.

  • Publication number: 20090220522
    Abstract: The present invention describes a detoxified Gram negative J5 core lipopolysaccharide/group B meningococcal outer membrane protein complex vaccine given in conjunction with CpG 7909 adjuvant. This vaccine composition can be used for either active or passive immunization of mammals for the prevention or treatment of sepsis and infection with Gram negative bacteria. The addition of CpG to the vaccine was shown to markedly increase the antibody response in mice. Furthermore, the ability of the endotoxin vaccine in protecting against Gram-negative bacteria such as Francisella tularensis in vivo is also demonstrated herein.

  • Patent number: 7259167
    Abstract: Disclosed herein is a pharmacophore model for antimalarial activity and methods of making and using thereof. The pharmacophore comprises two hydrogen bond acceptor (lipid) functions and two hydrophobic (aromatic) functions. The pharmacophore model was made using a test set of tryptanthrin compounds which exhibit antimalarial activity. Also disclosed are tryptanthrin compounds having greater solubility and bioactivity as compared to prior art tryptanthrin compounds and methods of making and using thereof. Also disclosed are methods of treating malaria in a subject.

  • Patent number: 7084132
    Abstract: A stable form of artemisinin wherein an artelinic acid or artesunic acid is complexed with cyclodextrin analogs, preferably, ?-cyclodextrin. The complexed cyclodextrin artemisinin formulation shields the peroxide portion of the artemisinin backbone from hydrolytic decomposition rendering it stable in solution. Artelinic acid and cyclodextrin are placed into contact with one another to yield a 2:1 molecular species. Artesunic acid and cyclodextrin yield a 1:1 molecular species. The complexed cyclodextrin artemisinin formulation is effective for the treatment of malaria and is stable in solution for long periods of time.
