Abstract: The present invention discloses therapeutic compositions and methods for treating a patient having a tumor disease. Methods, and dietary compositions thereof, for determining a diet regime for a patient with a tumor disease include the steps of: providing a sample of the patient; profiling at least one biochemical parameter of the sample using a biochemical analyzer to obtain a profile; identifying a biologically-active molecular feature of the profile; correlating the feature with a biochemical pathway related to the tumor's metabolism or proliferation; determining the diet regime specific to the patient, wherein the diet regime includes at least one biologically-active molecule corresponding to the feature of the profile; and administering the diet regime to the patient in a therapeutically-effective dosage. Preferably, the sample is selected from the group consisting of: a tumor sample, biological tissue, an organ sample, blood, blood serum, blood plasma, and urine.

Abstract: Provided are methods for detecting the presence or absence of a pathogen, disease, or medical condition, or biomarker thereof, using an enzymatic activity assay. In one embodiment, the method provided utilizes competitive inhibition of an enzyme for detecting a pathogen, disease, or medical condition, or biomarker thereof, in a subject. The method comprises providing a biological sample from the subject that may or may not contain an endogenous substrate. A test reaction is provided by contacting the biological sample with an enzyme indicative of the biomarker of a pathogen, disease, or medical condition and a substrate comprising a signaling moiety. The enzyme modifies the endogenous substrate and the substrate comprising the signaling moiety. Modification of the substrate comprising the signaling moiety by the enzyme produces a signal from the signaling moiety. Data from a control reaction comprising the enzyme and the substrate comprising the signaling moiety is further provided.

Abstract: Compounds having quinone and quinone analogs useful for pharmaceutical preparations have now been found which inhibit cysteine proteases, in particular, caspases and 3C-cysteine proteases. The cysteine protease inhibitors of the present invention can be identified by their mode of action in disrupting the ability of cysteine proteases and, in particular, caspases to cleave a peptide chain. These compounds are useful in inhibiting cysteine protease or cysteine protease-like proteins and for treating infections diseases or physiopathological diseases or disorders attributed to the presence of excessive or insufficient levels of cysteine proteases.
