  • Patent number: 9370557
    Abstract: The invention relates to the use of bacterial cytolysin proteins, such as pneumolysin, as adjuvants for stimulating or enhancing immune responses against co-administered target antigens. Desirably, the target antigen is provided as a fusion protein with the cytolysin. The inventors have found that cytolysins may be particularly effective for stimulation of mucosal immune responses against the target antigen.

  • Patent number: 8877750
    Abstract: The use of a compound comprising formula (I): or a salt, ester, amide or prodrug thereof in the inhibition of an enzyme whose preferred mode of action is to catalyse the hydrolysis of an ester functionality, e.g. in the control and inhibition of unwanted enzymes in products and processes. The compounds are also useful in medicine e.g. in the treatment of obesity and related conditions. The invention also relates to novel compounds within formula (I), to processes for preparing them and pharmaceutical compositions containing them. In formula (I) A is a 6-membered aromatic or heteroaromatic ring; and R1 is a branched or unbranched alkyl (optionally interrupted by one or more oxygen atoms), alkenyl, alkynyl, cycloalkyl, cycloalkenyl, aryl, arylalkyl, reduced arylalkyl, arylalkenyl, heteroaryl, heteroarylalkyl, heteroarylalkenyl, reduced aryl, reduced heteroaryl, reduced heteroarylalkyl or a substituted derivative of any of the foregoing groups.

  • Patent number: 7820789
    Abstract: The invention relates to immunogenic compositions comprising mutant Streptococcus pneumoniae pneumolysin proteins. The invention further relates to such proteins and nucleic acids encoding these proteins. In particular embodiments, the invention is directed to an isolated mutant pneumolysin (PLY) protein, wherein the mutant PLY protein differs from the wild-type PLY protein of SEQ ID NO:1 presence of a mutation within the region of amino acids 144 to 161 of the wild type such that the toxicity of the mutant is reduced relative to that of the wild-type protein. In particular embodiments, the mutant PLY protein differs from the wild-type protein by the substitution or deletion of amino acids including the deletion of two adjacent amino acids within the region of amino acids 144 to 151 of the wild-type sequence.

  • Patent number: 6716432
    Abstract: Mutants of pneumolysin that are non-toxic by reason of amino acid substitutions have been constructed. These mutants elicit an immune response in animals that is reactive to wild-type pneumolysin. The invention also encompasses vaccines for humans based on these mutants, including vaccines comprising conjugates with pneumococcal capsular polysaccharides.
