The present invention relates to a compound represented by formula (I-0):wherein symbols in formula have the same meanings as described in the present specification, a salt thereof, an N-oxide thereof or a solvate thereof or a prodrug thereof, and medical use thereof. The compound of the present invention has an antagonistic activity against CXCR4 and is therefore useful as a preventive and / or therapeutic agent for CXCR4-mediated diseases, for example, inflammatory and immune diseases (for example, rheumatoid arthritis, arthritis, retinopathy, pulmonary fibrosis, transplanted organ rejection, etc.), allergic diseases, infections (for example, human immunodeficiency virus infection, acquired immunodeficiency syndrome, etc.), psychoneurotic diseases, cerebral diseases, cardiovascular disease, metabolic diseases, and cancerous disease (for example, cancer, cancer metastasis, etc.), or an agent for regeneration therapy.

The present invention relates to an injectable nanoparticulate immunosuppressant composition for the formation of a subcutaneous or intramuscular depot. The invention is also directed to an injectable composition of nanoparticulate tacrolimus and / or sirolimus which eliminates the need to use polyoxyl 60 hydrogenated castor oil (HCO-60) and / or polysorbate 80 as a solubilizer. This invention further discloses a method of making an injectable nanoparticulate tacrolimus and / or sirolimus composition and is also directed to methods of treatment using the injectable nanoparticulate formulations comprising tacrolimus, sirolimus, or combination thereof for a subcutaneous or intramuscular depot for the prophylaxis of organ rejection and for the treatment of psoriasis or other immune diseases.

The present invention relates to methods of diagnosing and predicting organ transplant rejection. In particular, the present invention relates to the detection and prediction of kidney transplant rejection by detection of CXCR3 and CCL chemokines in urine. The present invention provides improved methods of diagnosing organ rejection and determining the efficacy of anti-rejection drugs.

The invention relates to the inhibition of blood coagulation, especially during organ rejection, and in particular the inhibition of delayed vascular rejection. The invention provides anticoagulant proteins which are anchored to cell membranes. The anticoagulant function preferably provided by heparin, antithrombin, hirudin, TFPI, tick anticoagulant peptide, or a snake venom factor. These anticoagulant proteins are preferably prevented from being constitutively expressed at the cell surface. In particular, expression at the cell surface is regulated according to cell activation, for instance by targeting the protein to a suitable secretory granule. Expression of these proteins renders cells, tissues and organs less vulnerable to rejection after transplantation (e.g. after xenotransplantation).

Novel Amino Acid Derivatives and Pharmaceutical Uses Thereof Provided are novel compounds of Formula I:wherein ‘X’ represents an amino acid group, ‘n’ is an integer between 1 and 4, ‘R1’ represents benzyl, t-butyl or 9-fluorenylmethyl and ‘R2’ represents a tetramethylmercaptoimidazole derivative or —S+R3R4, wherein R3 and R4 each independently represent lower alkyl, or a pharmaceutically and / or veterinarily acceptable derivative thereof. Further provided are pharmaceutical formulations of the compounds and the use thereof in the preparation of a medicament for inhibiting diseases in which transglutaminase has been implicated. Advantageously, the medicament is for treating fibrosis, scarring and / or cancer. Additionally provided are methods, of inhibiting autoimmune diseases such as coeliac disease, neurodegeneration and chronic inflammatory diseases (e.g. of the joints including rheumatoid arthritis and osteoarthritis in a subject) and a method for preventing or treating rejection of a transplanted organ.

The present invention relates to a method of suppressing organ rejection in a patient receiving an organ transplant by initiating oral treatment with a once-daily extended release tacrolimus dosage form, for example, at an initial dose of from about 0.15 to about 0.20 mg / kg / day within 24 or 48 hours following transplantation. The once-daily extended release tacrolimus dosage form (i) provides low fluctuation and / or swing of tacrolimus, (ii) provides a significantly lower Cmax than an immediate release formulation of tacrolimus while providing the same or greater area under the curve (AUC), (iii) releases the tacrolimus substantially in the colon and / or the lower ileum, (iv) releases at most 63.5% of the tacrolimus in the dosage form at the 12 hour time point, or (v) any combination of any of the foregoing.

The present invention, at least in part, relates to the discovery of efficacious delivery of an RNAi agent (e.g., an siRNA) to a transplantable tissue. The agent may be used to minimize organ rejection, transplantation-mediated transmission of viral infection, and triggering of apoptosis in transplanted tissues. The RNAi agent(s) can be delivered as “naked” molecules, or using liposomal and other modes of delivery, to transplantable tissues. Such delivery can occur via perfusion of the RNAi agent in solution through the vasculature of a whole or partial organ; or tissues including transplantable cells and cell lines may be bathed, injected or otherwise treated with RNAi agents. Preferred transplantable tissues include, for example, pancreas, liver, kidney, heart, lung, and all cells and cell lines derived from such tissues (e.g., pancreatic islet cells that may, e.g., be transplanted as a treated population).

The invention refers to an FLT3 inhibitors for immune suppression. New methods are provided for suppressing the immune system and for treating immune related disorders. Therapies of the invention include administration of an FLT3 inhibitor compound to a subject in need thereof, such as a subject suffering from organ rejection, bone marrow transplant rejection, acquired immune deficiency syndrome, arthritis, aplastic anemia, graft-versus-host disease, Graves' disease, established experimental allergic encephalitomyelitis, multiple sclerosis, lupus, or a neurological disorder. Methods are also provided for screening therapeutic agents for treating immune disorders, including the use of a mouse having an elevated level of FLT3 receptor activity.
