摘要:
The present invention provides novel ruthenium based catalysts, and a process for preparing amines, by reacting a primary alcohol and ammonia in the presence of such catalysts, to generate the amine and water. According to the process of the invention, primary alcohols react directly with ammonia to produce primary amines and water in high yields and high turnover numbers. This reaction is catalyzed by novel ruthenium complexes, which are preferably composed of quinolinyl or acridinyl based pincer ligands.
摘要:
The present invention relates to a drug delivery device that is useful for topical treatment of various infections such as skin and nail, or vaginal infections. More specifically, the invention provides a device for topical administration of allicin to an infection site, comprising either one solid carrier or two adjacent solid carriers, dry alliin and dry alliinase, wherein either a mixture of said dry alliin and dry alliinase is contained within said one solid carrier or dry alliin and dry alliinase are each separately contained within each one of said two adjacent solid carriers, whereby in contact with the infection site and a wetting agent, the alliinase acts on the alliin and allicin is produced in situ and administered to the infection site
摘要:
A method of monitoring amount of milk consumed by an infant being breastfed by a breast is disclosed. The method comprises: determining variations in electric capacitance of the breast during breastfeeding, and correlating the electric capacitance variations to an amount of milk consumed by the infant.
摘要:
A novel process of preparing allyl-containing asymmetric disulfides, and particularly therapeutically active allyl-containing asymmetric disulfides such as allylmercaptocaptopril (CPSSA) is disclosed.
摘要:
The present invention provides IFNα2 mutants and active fragments, analogs, derivatives, and variants thereof that have improved specific agonist or antagonist activity as compared to wild-type IFNα2. The present invention further provides pharmaceutical compositions comprising IFNα2 mutants useful for treating or preventing cancer, autoimmune diseases, infectious diseases or disorders associated with increased expression of IFNα2.
摘要:
A method of analyzing a blood-brain barrier of a subject is disclosed. A detectable dose of an MRI contrast agent is administered to the subject, and a plurality of magnetic resonance images of the subject's brain are acquired over a predetermined time-period. Two or more of the magnetic resonance images are compared thereamongst so as to determine variations in concentration of the contrast agent in the brain, and blood-brain barrier function is assessed based on the variations.
摘要:
The present invention provides anti-angiogenic variants of pigment epithelium derived factor (PEDF) comprising at least one altered phosphorylation site, polynucleotides encoding same and uses thereof. Particularly, the present invention provides variants of human PEDF comprising at least one amino acid substitution at serine residues (24), (114), and (227). The PEDF variants are potent anti-angiogenic factors, and thus useful in treating diseases or disorders associated with neovascularization.
摘要:
Peptides corresponding partially to positions 55-64 of the sequence of the complement component peptide C3a are capable of preventing and treating mast cell- and basophil-mediated disorders by inhibiting IgE- or IgG-mediated triggering and/or by inhibiting the FcεRI- and/or FcγR-induced secretory response, while obviating the anaphylatoxic response. These peptides are useful for prevention and/or treatment of allergic disorders where mucosal-type and/or serosal-type mast cells and/or basophils are involved such as asthma, allergic dermatosis, and gastrointestinal allergies.
摘要:
The present invention provides improved vaccines comprising an isolated viral antigenic peptide and a synthetic peptide derived from a T cell epitope of HSP60. The invention includes mixtures where the peptide serves as an adjuvant as well as conjugates where the peptide is covalently linked to the viral antigen. The known synthetic peptide carrier, p458, provides significantly improved immunogenicity for synthetic viral epitopes and analogs. Ec27 is a novel peptide derived from HSP60 which increases the immunogenicity substantially of the viral antigen both as a mixture or a covalent conjugate. Some of the isolated viral epitopes are novel and are claimed for diagnostic as well as therapeutic or prophylactic uses.
摘要:
Compositions comprising nucleic acids encoding the α chain of IL-2 receptor (IL-2Ra, CD25), homologs and fragment thereof, are effective in the treatment and prevention of T cell mediated pathologies. Methods are provided for enhancing anti-ergotypic T cell activity in a subject in need thereof, and for treating or preventing T cell mediated pathologies, such as autoimmune disease, inflammatory diseases and graft rejection.
