  • Publication number: 20090011975
    Abstract: The invention provides a method of inhibiting cell death in a mammal. The method comprises administering to a mammal an effective amount of a composition comprising a cell protection factor covalently linked to a bone targeting agent via a linkage that is cleaved under physiological conditions, whereby the cell protection factor is released from the bone targeting agent in vivo to inhibit cell death. The invention further provides a compound comprising a cell protection factor covalently attached to a bone targeting agent via a linker that is cleaved under physiological conditions.

  • Publication number: 20080292714
    Abstract: This invention provides a method of modifying a cellular response in a mammal. The method comprises administering to the mammal an effective amount of biodegradable nanoparticles, each of said nanoparticles comprising an active agent, a biodegradable polymer, and a bone targeting agent administering to a mammal an effective amount of a composition comprising a compound absorbed in a biodegradable nanoparticle which is attached to a bone targeting agent. The invention also provides a method for modifying a cellular response in a mammalian cell comprising contacting the mammalian cell with biodegradable nanoparticles. The invention further provides a method of delivering an exogenous substance to a mammal. The method comprises administering to the mammal a composition comprising the exogenous substance absorbed into a biodegradable nanoparticle, wherein the biodegradable nanoparticle is covalently attached to a bone targeting agent.

  • Patent number: 6991788
    Abstract: Described herein are methods for producing recombinant forms of asparaginase derived from Wolinella succinogenes. In addition, methods for covalent modification of proteins, including asparaginases, by acylation are also provided. Certain embodiments provide for epitopic-labeling of the amino terminus of W. succinogenes asparaginase. Additional embodiments concern methods for the therapeutic utilization of the native, homotetrameric form of W. succinogenes asparaginase, as well as the use of epitopically-labeled or non-epitopically-labeled recombinant W. succinogenes asparaginase (or a covalently modified analog thereof) in the therapeutic treatment of malignant and non-malignant hematological disease and other diseases where asparagine depletion or deprivation would be efficacious or which respond to asparagine depletion or deprivation, as well as their potential utilization in the therapeutic treatment of autoimmune diseases such as rheumatoid arthritis, AIDS, and SLE.
