  • Adjuvants for vaccines
    Patent number: 6340464
    Abstract: Vaccine adjuvants comprising a liquid medium contain polymers with anionic constitutive repeating units and hydrophobic constitutive repeating units. Advantageously, the adjuvants are aqueous solutions of partially esterified polyacrylic acids. The novel adjuvants are highly stable, effective and have a relatively low level of local toxicity. Further, vaccines comprising such adjuvants and a process for producing them are described.

  • N-hydroxy-2-(alkyl, aryl, or heteroaryl sulfanyl, sulfinyl or sulfonyl)-3-substituted alkyl, aryl or heteroarylamides as matrix metalloproteinase inhibitors
    Publication number: 20020006922
    Abstract: Matrix metalloproteinases (MMPs) are a group of enzymes that have been implicated in the pathological destruction of connective tissue and basement membranes. These zinc containing endopeptidases consist of several subsets of enzymes including collagenases, stromelysins and gelatinases. TNF converting enzyme (TACE), a pro-inflammatory cytokine, catalyzes the formation of TNF-&agr; from membrane bound TNF-&agr; precursor protein. It is expected that small molecule inhibitors of MMPs and TACE therefore have the potential for treating a variety of disease states.

  • Vaccine adjuvants
    Patent number: 6328965
    Abstract: Vaccine adjuvants comprising a sulpholipid polysaccharide in combination with an interface-forming constituent. The invention also provides a method for preparing a vaccine by emulsifying an aqueous solution of an antigen and a sulpholipid polysaccharide. The adjuvants are stable at high temperatures, and are at least as effective as conventional adjuvants. Their local toxicity, i.e. their reactogenicity, is generally lower than that of conventional adjuvants.

  • Recombinant BHLH-PAS/JHR polypeptide and its use to screen potential insecticides
    Patent number: 6326165
    Abstract: Promising groups of environmentally-safe insecticides consist of analogues of insect hormones, such as juvenile hormone, and antagonists of such hormones. The traditional bioassay approach for screening potential juvenile hormone analogs and antagonists is slow, expensive and inefficient. A recombinant bHLH-PAS-juvenile hormone receptor, isolated from methoprene-tolerant locus on Drosophila, provides the basis of in vitro and in vivo binding assays that can be used to discover new juvenile hormone-type targeted insecticides. Moreover, the nucleotide sequence of the Drosophila bHLH-PAS/JHR polypeptide provides tools for isolating juvenile hormone receptor genes from other insect species.

  • Valve assembly for use with containers in a closed application system
    Patent number: 6305444
    Abstract: A container for use in a closed application system includes a valve mounted to a discharge opening of the container and rotatable with the container for controlling the discharge of material from the container. The valve includes an element for engaging corresponding structure in a receptacle for receiving the contents of the container. The element engages and locks the valve in the receptacle when the valve is opened and the contents are being discharged from the container into the receptacle. The valve element and the corresponding structure on the receptacle cooperate so that the container can only be received in and removed from the receptacle when the valve is closed. In this manner, the contents in the container can be discharged only when the container is received within the receptacle and the container is rotated in a direction to open the valve.
