  • Patent number: 7045543
    Abstract: This invention herein describes a method of facilitating the entry of drugs into cells and tissues at physiologically protected sites at pharmacokinetically useful levels and also a method of targeting drugs to physiologically protected sites in vivo. Also provided are drug conjugates with an amino acid or derivative thereof for facilitating such targeted drug delivery. The conjugates and methods of this invention provide an advance over other drug targeting methods known in the prior art, because the invention provides drug concentrations in such physiologically protected sites that can reach therapeutically-effective levels after administration of systemic levels much lower than are currently administered to achieve a therapeutic dose. This technology is appropriate for use with psychotropic, neurotropic, neurological, antibiotic, antibacterial, antimycotic, antiviral, antiproliferative or antineoplastic drugs, agents and conjugates, for rapid and efficient introduction of such agents across, e.g.

  • Patent number: 6455073
    Abstract: This invention provides reagents and methods for specifically delivering antibiotic, antimicrobial and antiviral compounds, drugs and agents to phagocytic mammalian cells. The invention also relates to specific delivery to and uptake of such compounds by phagocytic cells. The invention specifically relates to reagents and methods for facilitating the entry of antibiotic, antimicrobial and antiviral compounds, drugs and agents into phagocytic cells. The invention specifically provides compositions of matter and pharmaceutical embodiments of such compositions comprising such antibiotic, antimicrobial or antiviral compounds, drugs and agents conjugated to, impregnated with or coated onto particulate carriers generally termed microparticles. In particular embodiments, the antibiotic, antimicrobial and antiviral compounds, drugs and agents are covalently linked to a microparticle via a specifically-degradable linker molecule which is the target of a microorganism-specific protein having enzymatic activity.
