THERAPEUTIC DELIVERY USING COMPOUNDS SELF-ASSEMBLED INTO HIGH AXIAL RATIO MICROSTRUCTURES

摘要

Therapeutic complexes comprising plural therapeutic compounds self assembled into high axial ratio microstructures are described. The therapeutic complexes satisfy the formula HARM-Th, wherein HARM is a high axial ratio forming material and Th is a therapeutic coupled to or associated with the HARM. The therapeutic complexes also can satisfy the formula HARM- S- Th, wherein S is a spacer. Release of the therapeutic by the complex generally follows either 0-order kinetics or pseudo-first order kinetics. A method for delivering therapeutics to organisms, particularly humans, also is described. The method comprises administering an effective amount of (1) a ligand, such as a therapeutic, self-assembled into a HAR microstructure, or (2) a ligand, such as a therapeutic, coupled to or associated with a material capable of thereafter self-assembling into a high axial ratio microstructure, to the mammal. Nucleic acids are an example of a ligand that can be administered effectively according to this method through noncovalent attachment to the HARM-forming materials.
