    摘要: The fluorinated curcuminoid (3,5-bis-(2-fluorobenzylidene)-piperidin-4-one-acetate is about ten times more effective at arresting the growth of tumor cells than cisplatin. The present invention provides methods to deliver a cytotoxic compound, such as a curcuminoid, specifically to cancer cells and to the vascular endothelial cells that nourish solid tumors. The method involves tethering the drug to a protein such as in factor VIIa that retains high affinity for the surface protein tissue factor. Upon complexation, the resulting heterodimer is endocytosed and the drug is subsequently liberated inside the target cell via proteolytic cleavage. The present invention further provides for the synthesis of novel curcuminoid-tether-linker-factor VIIa compositions and for methods of delivery of effective doses of the novel compositions to target tumor or endothelial cells in a patient

    摘要: The invention provides sulfur-linked and nitrogen-linked peptidic conjugates of curcumin analogs that can provide increased water solubility and photostability as compared to the corresponding unmodified curcumin analogs without sacrificing therapeutic efficacy. The conjugates, which are believed to act as prodrugs, can be used therapeutically in the same manner as the unmodified curcumin analogs, such as in the treatment or prevention of cancer, diabetes, or inflammatory diseases. One conjugate comprises 3,5-Bis-(2-fluorobenzylidene)-piperidin-4-one, or a salt thereof, covalently attached through a sulfur linkage to a thiol-containing peptide such as glutathione.

    摘要: Compositions and methods are provided for delivering cytotoxic compounds, such as natural curcumoids and synthetic curcumin analogs, specifically to cancer cells and to blood vessels that nourish solid tumors. The compositions include a cytotoxic drug tethered to a protein, such as factor VIIa, which can bind with high affinity to a receptor, such as tissue factor, expressed on the surface of cancer cells and vascular endothelial cells within the tumor microenvironment. Upon binding, the drug-protein-receptor complex is endocytosed and the drug is subsequently liberated inside the target cell via proteolytic cleavage. The compositions and methods may increase the efficacy of the cytotoxic agets and decrease their side effects by delivering the agents to specific target cells, such as cancer cells, vascular endothelial cells in a tumor, and metastatic foci anywhere in the body, providing the target cells express surface bound tissue factor. Additionally, methods of synthesis of cytotoxic compound-protein conjugates are provided, for example, curcuminoid-tether-linker-factor VIIa composition, as well as pharmaceutically acceptable compositions and methods for delivering a therapeutically-effective amount of a cytotoxic compound-protein conjugate together with one or more pharmaceutically acceptable carriers (additives) and/or diluents to an animal or human patient.

    摘要: The fluorinated curcuminoid (3,5-bis-(2-fluorobenzylidene)-piperidin-4-one-acetate is about ten times more effective at arresting the growth of tumor cells than cisplatin. Conjugates for delivering a cytotoxic compound, such as a curcuminoid, specifically to cancer cells and to the vascular endothelial cells that nourish solid tumors, and methods of making and using thereof are described herein. The conjugate contains a cytotoxic compound bound to a protein such as in factor VIIa that retains high affinity for the surface protein tissue factor. The cytotoxic compound is bound to the protein via a linker and a hydrolyzable bond. Upon complexation, the resulting heterodimer is endocytosed and the drug is subsequently liberated inside the target cell via proteolytic cleavage.
