摘要:
The present invention discloses a drug-carrying contact lens and a method for fabricating the same. The drug-carrying contact lens comprises a contact lens containing at least one amphiphatic hybrid nanocarrier carrying drug molecules. According to the heat or light sensitivity of the drug molecule, the present invention respectively fabricates an encapsulation-type drug-carrying contact lens and a drug-soaking type drug-carrying contact lens. The present invention uses a highly-biocompatible amphiphatic hybrid nanocarriers having superior drug encapsulation capability to wrap the drug molecules. Thereby, the drug molecules are uniformly distributed in the contact lens and can be gradually and locally released to the eye of the user wearing the contact lens. Therefore, the present invention can prevent or cure ocular diseases with the loss and side effects of the drug being reduced.

Provided is a polymersome composition that has skin disorder remedying effects, that is safe, that provides a pleasant feel upon use and a fresh feel without any stickiness, and that has excellent base-agent stability. The disclosed polymersome contains, as a membrane component, a block-type alkylene oxide derivative represented by the following formula (I): R1O-[(EO)l(AO)m(EO)n]-R2. (In the formula, AO represents an oxyalkylene group having 3 or 4 carbons; EO represents an oxyethylene group; m represents an average addition mole number of the oxyalkylene group and satisfies 1=m=70; and 1+n represents an average addition mole number of the oxyethylene group and satisfies 1=1+n=70. The percentage of the oxyethylene group to the sum of the oxyalkylene group having 3 or 4 carbons and the oxyethylene group is 20% to 80% by mass. The oxyalkylene group having 3 or 4 carbons and the oxyethylene group are added blockwise. R1 and R2 each represent a hydrocarbon group having 1 to 4 carbons, which may be the same or different from each other.)

摘要:
The present invention provides for the development of endocytosis-sensitive probes, and a remote method for measuring cellular endocytosis. These probes are based on the reduced water permeability of a nanoparticle or liposomal delivery system, and inherent degradability or disruption of barrier integrity upon endocytosis. The invention also provides for liposomes having combined therapeutic and diagnostic utilities by co-encapsulating ionically coupled diagnostic and therapeutic agents, in one embodiment, by a method using anionic chelators to prepare electrochemical gradients for loading of amphipathic therapeutic bases into liposomes already encapsulating an imaging agent. The invention provides for imaging of therapeutic liposomes by inserting a lipopolymer anchored, remotely sensing reporter molecules into liposomal lipid layer. The invention allows for an integrated delivery system capable of imaging molecular fingerprints in diseased tissues, treatment, and treatment monitoring.

Described are amphiphilic polymers that are provided with chelating moieties. The amphiphilic polymers are block copolymers comprising a hydrophilic block and a hydrophobic block, with the chelating moieties linked to the end-group of the hydrophilic block. The disclosed polymers are capable of self-assembly into structures such as micelles and polymersomes. With suitable metals present in the form of coordination complexes with the chelating moieties, the chelating amphiphilic polymers of the invention are suitable for use in various imaging techniques requiring metal labeling, such as MRI (T 1 /T 2 weighted contrast agents or CEST contrast agents) SPECT, PET or Spectral CT.

摘要:
The present invention provides an amphiphilic molecule having a plurality of zwitterionic functional groups in its hydrophilic moiety and a molecular assembly comprising the amphiphilic molecule as a constituent lipid. According to a preferred embodiment of the present invention, the molecular assembly of the present invention forms a stable vesicular structure under a physiological pH environment to carry a substance of interest in the vesicular structure, and can release the substance of interest to the outside of the vesicular structure when it is deformed under an acidic pH environment. The molecular assembly of the present invention can be used as a carrier for a drug, a probe, a nucleic acid, a protein or the like.
摘要:
There is provided targeting drug delivery system (DDS) nanoparticles that can be accumulated in target tissues such as inflammatory sites of inflammatory diseases and can thus be utilized in a therapeutic or diagnostic DDS for locally delivering drugs or genes to the affected parts. The present invention provides a pharmaceutical composition for the medical treatment or diagnosis of an inflammatory disease comprising a sugar-modified liposome having a sugar chain bound to the membrane of the liposome.
