392 results about "Mast cell" patented technology

Compounds represented by general formula (I) (all of the symbols in the formula conform to the definitions in the Description) are compounds that, in addition to having a Btk-selective inhibitory activity, exhibit an excellent metabolic stability and can avoid hepatotoxicity or the like, and as a consequence can provide safe therapeutic agents for diseases in which B cells or mast cells participate.

The purinone derivative 6-amino-9-[(3R)-1-(2-butynoyl)-3-pyrrolidinyl]-7-(4-phenoxyphenyl)-7,9-dihydro-8H-purin-8-one hydrochloride has Btk-selective inhibitory activity and, in addition to having excellent metabolic stability, it is a compound that exhibits a high level of solubility and absorption with respect to the free base and can be crystallized, hence it can serve as a therapeutic agent for diseases involving B cells and mast cells.

Liquid aqueous pharmaceutical solutions, containing a mast cell stabilizing active agent for application to the upper and lower respiratory tract or in the eye are provided. The solutions comprise both a non-ionic and an ionic tonicity-adjusting excipient. They are particularly useful for the aerosol treatment of respiratory diseases such as asthma. Furthermore, methods for nebulization of these solutions and methods of packaging the solutions are provided.

Methods for agents useful for treating asthma are disclosed. The methods include screening for agents that inhibit the production of a PKC-θ protein, as well as for agents that inhibit the kinase activity of a PKC-θ protein, or a functional fragment thereof, wherein such agents are useful for treating asthma. The methods also include screening for agents that inhibit the production of a reporter gene product encoded by a nucleic acid sequence operably linked to a PKC-θ promoter. Also disclosed are methods of treating asthma that include administering an agent that inhibits the production of a functional PKC-θ protein or the kinase activity of a PKC-θ protein or a functional fragment thereof. An isolated mast cell lacking expression of endogenous PKC-θ is also disclosed.

The present invention provides novel purine and imidazopyridine derivatives useful for the prevention and treatment of autoimmune diseases, inflammatory disease, mast cell mediated disease and transplant rejection. The compounds are of the general formulas:

Compositions with synergistic anti-inflammatory effects in inflammatory diseases resulting from activation and consequent degranulation of mast cells and followed by secretion of inflammatory biochemicals from the activated mast cells, the compositions containg one or more of a flavone or flavonoid glycoside a heavily sulfated, non-bovine proteoglycan, an unrefined olive kernel extract that increases absorption of these compositions in various routes of administration, a hexosamine sulfate such as D-glucosamine sulfate, S-adenosylmethionine, a histamine-1 receptor antagonist, a histamine-3 receptor agonist, an antagonist of the actions of CRH, a long-chain unsaturated fatty acid, a phospholipid, Krill oil, a polyamine, glutiramer acetate and interferon. Certain of the present compositions are useful in protecting against the neuropathological components of multiple sclerosis and similar inflammatory neurological diseases.

Methods for the treatment of systemic disorders treatable with mast cell stabilizers, including mast cell related disorders, are provided.

The invention provides methods of delivering pharmacologic agents linked to an internalization peptide, in which an inflammatory response inducible by the internalization peptide is inhibited by co-administration of an anti-inflammatory or by linking the internalization peptide to biotin or similar molecule. Such methods are premised in part on the results described in the examples whereby administration of a pharmacological agent linked to tat high dosages is closely followed by an inflammatory response, which includes mast cell degranulation, histamine release and the typical sequelae of histamine release, such as redness, heat, swelling, and hypotension.

The invention provides methods of treating a disease selected from systemic sclerosis, rheumatoid arthritis, mastocytosis, and chronic eosinophilic leukemia comprising administering biaryl meta-pyrimidine compounds having the general structure (A) to a subject in need thereof. The pyrimidine compounds of the invention are capable of inhibiting kinases, such as members of the JAK kinase family, and various other specific receptor and non-receptor kinases.

Compositions with synergistic anti-inflammatory effects in inflammatory diseases resulting from activation and consequent degranulation of mast cells and followed by secretion of inflammatory biomolecules from the activated mast cells, composed of a heavily sulfated, non-bovine proteoglycan such as shark cartilage chondroitin sulfate C, an unrefined olive kernel oil/extract that increases absorption of these compositions in various routes of administration, and one or more of a hexosamine sulfate such as D-glucosamine sulfate, a flavone such as quercetin, S-adenosylmethionine, a histamine-1 receptor antagonist, a histamine-3 receptor agonist, an antagonist of the actions of CRH, caffeine, and a polyamine.

Novel activating receptors of the Ig super-family expressed on human myeloid cells, called TREM(s) (triggering receptor expressed on myeloid cells) are provided. Specifically, two (2) members of TREMs, TREM-1 and TREM-2 are disclosed. TREM-1 is a transmembrane glycoprotein expressed selectively on blood neutrophils and a subset of monocytes but not on lymphocytes and other cell types and is upregulated by bacterial and fungal products. Use of TREM-1 in treatment and diagnosis of various inflammatory diseases is also provided. TREM-2 is also a transmembrane glycoprotein expressed selectively on mast cells and peripheral dendritic cells (DCs) but not on granulocytes or monocytes. DC stimulation via TREM-2 leads to DC maturation and resistance to apoptosis, and induces strong upregulation of CCR⁷ and subsequent chemotaxis toward macrophage inflammatory protein 3-β. TREM-2 has utility in modulating host immune responses in various immune disorders, including autoimmune diseases and allergic disorders.

The present invention provides novel purine and imidazopyridine derivatives useful for the prevention and treatment of autoimmune diseases, inflammatory disease, mast cell mediated disease and transplant rejection. The compounds are of the general formulas:

Compounds and methods for the treatment of asthma are disclosed. The methods involve mast cell stabilization together with selective inhibition of iNOS. The compounds are combinations of a mast cell inhibiting moiety and an inhibitor of iNOS. An example is:

Compositions suitable for reducing symptoms of an allergic response to environmental allergens comprising molecules that specifically inhibit the ability of the allergen to bind to mast cells in an animal predisposed to having an allergic response to the allergen and methods for reducing such symptoms comprising contacting a source of the environmental allergen with such compositions. Kits, packages, medicaments, and means of communicating about the compositions and methods are also provided.
