摘要:
There is provided an electrochemical assay method for detecting a target molecule, for example a protein, in a sample, which involves the use of a protective monolayer and a redox polymer to form a bilayer immobilized on an electrode. The monolayer protects the electrode from non-specific adherence of reagents, particular proteins, to the electrode while simultaneously providing a surface that can be functionalized to immobilize a capture molecule and that can interact with the redox polymer.
摘要:
Peptides that have potent PLA2-inhibitory activity are disclosed. Homology searches of known PLA inhibitory molecules were used to identify and subsequently design potent peptide molecules that can induce neuroprotective as well as anti-inflammatory effect. These peptides were shown to protect against degeneration of joints in transgenic mouse model prone to arthritis. Protection from kainate-induced excitotoxic neuronal injury was also observed using these peptides. These peptides, their analogs and derivatives have potential as neuroprotective and/or anti-inflammatory agents in a clinical setting.
摘要:
The present invention provides a new 18-residue homodimerized peptide, designated PIP [59-67] dimer (SEQ ID NO: 1), which is a mutant of the optimized anti-inflammatory peptide P-NT.II, the patent for which has recently been filed [1]. P-NT.II has the potential to modulate both the inflammatory and bone damaging components of rheumatoid arthritis, and was originally designed on the basis of the primary structure of the anti-inflammatory protein termed ‘Phospholipase Inhibitor from Python (PIP)’ [2]. Using solid phase chemistry, variants of P-NT.II were designed and examined for inhibitory activity against secretory phospholipase A2 (sPLA2), a key enzyme involved in the inflammatory pathway, and matrix metalloproteinases (MMPs) that are involved in the remodeling and degradation of the extracellular matrix in rheumatoid arthritis (RA) and cancer. Among the family of mutants tested, the dimerized peptide was found to be the most potent inhibitor against sPLA2 as well as the human recombinant MMP-1. This invention provides the utility of the peptide analogue PIP [59-67] dimer as a potential therapeutic agent for modulation of inflammatory diseases such as rheumatoid arthritis, and cancer. This invention relates to all the polypeptide analogues (SEQ ID NO: 1 to 3) and polynucleotides (SEQ ID NO: 4), and to the use of those polypeptides and polynucleotides, their synthetic chemical analogues or variants that inhibit activity and synthesis of sPLA2 and MMPs, in the diagnosis, study, prevention and treatment of rheumatoid arthritis and/or cancer.

摘要:
A phospholipase A2 inhibitor protein designated “Phospholipase Inhibitor from Python” (PIP)—formerly designated “Python Antitoxic Factor” (PAF)—is given by SEQ ID NO:2. The partial amino acid sequence for PIP was initially determined from the native protein purified from the blood serum of a non-venomous snake, Python reticulatus. The complete PIP polynucleotide sequence was obtained from a cDNA clone encoding PIP, given by SEQ ID NO:1, along with the full amino acid sequence deduced from it. Also disclosed is a recombinant protein PIP, which shows strong lethal toxin neutralizing activity similar to the native PIP, and has potent anti-inflammatory activity. Both the native and the functionally equivalent recombinant PIP are useful for the prevention or treatment of conditions such as snakebites, insect stings, and inflammatory diseases. Also, phospholipase A2 (PLA2) inhibitory polypeptides designated P-0029, P-0009, and P-0006, the sequences of which are given as SEQ ID NO:10, SEQ ID NO:11, and SEQ ID NO:12, respectively, are disclosed. Those polypeptides, and their synthetic chemical analogues and polypeptide variants that inhibit PLA2 activity and alleviate inflammation, may also be used in the diagnosis, study, prevention, and treatment of PLA2-related human inflammatory diseases.
