    Abstract: Preparations comprising a capsule, tablet or other dosage form containing a core of different types of DFMO are provided. These preparations are capable of providing for the direct and constant delivery of DFMO to the entire GI tract or just the colon and rectum. The DFMO-containing granules include granules specially formulated to achieve rapid DFMO release, and granules formulated to achieve slower DFMO release and/or granules formulated for gastric, enteric or colorectal release. Methods of using the preparations to flood the GI tract with relatively constant levels of DFMO may thus be provided. The ratio of the (+) to the (-)-enantiomeric forms of DFMO in the granules will be controlled so as to enhance the pharmacological profile and reduce toxicity of the preparation relative to racemic DFMO. Preparations and methods for achieving systemic delivery as well as direct colon delivery of DFMO are also described.

    Abstract: Dual indicator agents having synergistically enhanced fluorescent properties are provided that include a nitroxide moiety and a nitroxide free radical center. The indicator molecule may include any variety of chemical or biochemical marking agents, such as a fluorescent molecule. The dual agent may further include a spacer molecule or linker, that will function to attach the indicator molecule, such as a fluorescent moiety, to the nitroxide moiety. These may be used to measure the redox potential in living cells, as well as to determine redox potentials in diagnostics, as well as in many other applications.

    Abstract: Preparations comprising a single enantiomer or defined non-racemic ratio of enantiomers of alpha-difluoromethylornithine (DFMO) are provided for treating, preventing, controlling the growth of and/or reducing the risk of cancers, tumors and other related neoplastic disorders. The preparations containing a substantially pure preparation of (-)-DFMO or a defined non-racemic ratio of DFMO enantiomers will provide an enhanced pharmacological activity relative to a preparation comprising racemic DFMO.

    Abstract: Compositions of fluorescent amplifier molecules are provided, as well as synthetic methods for their preparation. The procedures provide for the preparation of gram quantities of fluorescent molecules from available precursors. The fluorescent amplifier molecules include a multi-dimensional, rigid core (C), to which at least two fluorescent moieties are attached by way of a linker (L). Amplifier molecules that further include a "targeting" molecule (a molecule that functions to direct the fluorescent amplifier to a particular binding site) are also presented, the targeting molecule being attached to the rigid, multi-dimensional core. Signal amplification without steric restrictions of fluorophore mobility is provided, hence reducing and/or avoiding interactions between moieties as well as fluorescence quenching. The advantage of the derivatives of the present invention, in addition to other things, over conventional fluorescent labels is due to the ability to amplify signal upon accumulation of the fluorescent moieties. The new amplified molecules are further disclosed to have the capability to quantitate the fluorescence signal. the compositions may also be employed as nucleic acid fluorescent -in-situ-hybridization probes.
