    Abstract: The present disclosure provides contrast photoacoustic probes, and compositions comprising such probes, designed to non-invasively detect and monitor various disease states, or targets within a subject human or animal. The probes are designed to be optically excited in tissue, ultimately generating thermal energy, which is transformed into acoustic energy by the response of the aqueous environment in the subject to the thermal emissions. The acoustic energy (sound) can then be detected by suitably applied transducers and digitally transformed into images indicating the location of the probe in the subject. One aspect of the disclosure encompasses photoacoustic probes that comprise: a carbon nanotube and a plurality of dye molecules bound to the carbon nanotube. The probes may further comprise a targeting moiety for localizing the probe at the site of a specific target.

  • Patent number: 7169611
    Abstract: The compositions and methods disclosed herein provide heterobifunctional programmable genotoxic compounds that can be designed to kill selected cells present in a heterogenous cell population. The present compounds comprise a first agent that inflicts damage on cellular DNA, and a second agent that attracts a macromolecular cell component such as a protein, which in turn shields genomic lesions from repair. Unrepaired lesions therefore persist in the cellular genome and contribute to the death of selected cells. In contrast, lesions formed in nonselected cells, which lack the cell component, are unshielded and thus are repaired. As a result, compounds described herein are less toxic to nonselected cells. Compounds of this invention can be designed to cause the selective killing of transformed cells, viral-infected cells and the like.

More particularly, this invention pertains to a novel group of dammarane sapogenins, PAM-120, PBM-110 and PBM-100 (the dammarance sapogenine structure is specifically clean of any sugar moieties (glycons) at any position and hydroxyl at C-20) and PAN-20 and PAN-30 (the dammarance sapogenin structure has sugar moieties but is free of hydroxyl at C-20), obtained by chemical cleavage of dammarane saponins. The invention also includes a novel application of the said sapogenins for anti-cancer treatment by using them separately or together, and/or jointly with other drugs, as well as to the process of producing these novel sapogenins. Said novel dammarane sapogenins show surprising anti-cancer effect when applied, particularly against multi-drug resistant cancers.

  • Patent number: 6844456
    Abstract: The present invention is directed to modified, hydroxy-bearing aromatic ring structures having cytoprotective activity. More specifically, in a first embodiment the present invention is directed to phenolic compounds, and in particular steriods (e.g., estrogens), wherein a non-fused polycyclic, hydrophobic substituent is attached to the hydroxy-substituted A-ring thereof. The present invention is further directed to a process for conferring cytoprotection to a population of cells involving the administration of the compound.

  • Patent number: 6670348
    Abstract: Compounds having an ansamycin anitibiotic, or other moiety which binds to hsp90, coupled to a targeting moiety which binds specifically to a protein, receptor or marker can provide effective targeted delivery of the ansamycin antibiotic leading to the degradation of proteins and death of the targeted cells. These compositions may have different specificity than the ansamycin alone, allowing for a more specific targeting of the therapy, and can be effective in instances where the ansamycin alone has no effect. Thus, these compounds provide an entirely new class of targeted chemotherapy agents with application, depending on the nature of the targeting moiety, to treatment of a variety of different forms of cancer. Such agents can further be used to promote selective degradation of proteins associated with the pathogenesis of others diseases, including antigens associated with autoimmune disorders and pathogenic proteins associated with Alzheimer's disease.

  • Patent number: 6610866
    Abstract: A method is described for stereoselectively reducing an unsaturated alkyl ketone substituent attached to a fused ring base. In this method, the unsaturated alkyl ketone reacts with a chiral oxazaborolidine reagent. This reaction stereoselectively reduces the unsaturated alkyl ketone to an unsaturated alkyl alcohol. The unsaturated alkyl alcohol can be further reduced, if desired, to produce a saturated alkyl alcohol. The fused ring base can be, for example, a steroid ring base or a base of a vitamin D analog. The process in accordance with the invention can be used with an alkeneone substituent (e.g., a 22-ene-24-one substituent) or an alkyneone substituent (e.g., a 22-yne-24-one substituent) on a steroid ring base to make squalamine or other useful aminosterol compounds and intermediates for making aminosterol compounds.
