Abstract: Novel mutant A1 adenosine receptor cDNA sequences and plasmids. Novel mutant A1 adenosine receptor cDNA sequences and plasmids which can improve immune cells ability to kill cancer cells.

Abstract: The present inventions relates to methods of producing an antigenic response in which an antigen is contacted to an antigen-presenting cell, wherein the improvement comprises contacting the antigen-presenting cell with an A1 adenosine receptor activating agent in an amount sufficient to increase the antigenic response of the antigen-presenting cell to the antigen. The present invention further provides methods, compositions, combination therapies, imaging techniques, and diagnostic kits that may improve the diagnosis, prognosis, and/or survival of cancer patients, pathogen-infected patients, and infectious or non-infectious immune-deficient patients.

Abstract: This invention relates to a diagnostic probe comprising a compound of formula (I): such as 3-[2-[4-(5-aminopentyl-3-amidocarboxypropanoyl)]aminophenyl]ethyl]-8-benzyl-7-[2-ethyl(2-hydroxyethyl)amino]ethyl-1-propylxanthine, with one or more label moieties attached thereto. The compounds of the present invention are useful as diagnostic probes, including probes for diagnostic assays and imaging. Accordingly, the invention provides A1 adenosine receptor antagonist compounds with radioactive or non-radioactive labels suitable for executing such assays and imaging measurements. Labeled compounds are useful to obtain quantitative measurements of the A1 adenosine receptor antagonist compounds. They may be employed as an imaging agent in diagnostic procedures such as MRI and PET as well as cell or receptor based assays.

Abstract: wherein R3 is Alk14ArR16, and wherein Alk14 is C1-8 straight or branched alkylene or alkenylene. The present invention provides novel adenosine receptor antagonists, more particularly, A1 adenosine receptor antagonists of formula (I). Pharmaceutical compositions comprising an A1 adenosine receptor antagonist of formula (I) and a pharmaceutically acceptable carrier are further provided. Compositions also include diagnostic assay-type probes comprising a novel A1 adenosine receptor antagonist of formula (I) that is labeled or conjugated with radioactive or non-radioactive material. Methods for treating A1 adenosine receptor related disorders comprising administering an A1 adenosine receptor antagonist of formula I are also disclosed. The novel A1 adenosine receptor antagonist compositions of formula (I) find further use in diagnostic and imaging methods.

Abstract: Methods and compositions for treating and preventing sepsis are provided. The methods of the invention comprise administering to a subject a therapeutically effective amount of an A1 adenosine receptor antagonist in combination with an antibiotic agent. The invention further encompasses pharmaceutical compositions comprising a combination of an A1 adenosine receptor antagonist and an antibiotic agent in a pharmaceutically acceptable carrier. The pharmaceutical compositions of the invention find use in methods for treating and preventing sepsis.

Abstract: Methods for treating and preventing tissue injury and sepsis associated with a Yersinia pestis infection, particularly pneumonic plague, are provided. The methods of the invention comprise administering to a subject a therapeutically effective amount of an A1 adenosine receptor antagonist alone or in combination with at least one additional therapeutic agent, including an antibiotic agent. The present methods find use in biodefense as a means of preventing and treating tissue injury and sepsis associated with Y. pestis infection, particularly pneumonic plague, in the event of a bioterrorist attack with this deadly bacterium.
