  • Patent number: 10233277
    Abstract: Synthesis and characterization of starch based pH-responsive nanoparticles for controlled drug delivery are described. Polymethacrylic acid grafted starch (PMAA-g-St) nanoparticles with various molar ratio of starch to MAA were synthesized by a new one-pot method that enabled simultaneous grafting of PMAA and nanoparticle formation in an aqueous medium. NMR data showed that polysorbate 80 was polymerized into the graft polymer. Nanoparticles were relatively spherical with narrow size distribution and porous surface morphology and exhibited pH-dependent swelling in physiological pH range. The particle size and magnitude of volume phase transition were dependent on PMAA content and formulation parameters such as surfactant levels, cross-linker amount, and total monomer concentration. The results showed that the new pH-responsive nanoparticles possessed useful properties for controlled drug delivery.

  • Patent number: 9919059
    Abstract: Nanoparticles for a selective, two stage delivery to tumors have been developed. The nanoparticles are initially sized so that they preferentially accumulate in the tumor tissue as a result of leakage through the defective vascular in the solid tumors. Once in the tumor tissue, the nanoparticles are cleaved hydrolytically and/or by enzymatic cleavage over time to release smaller nanoparticles carrying therapeutic, prophylactic or diagnostic agents into the necrotic interior of the tumors. This provides a simple, elegant and highly effective means of delivery drug selectively not just to tumors generally, but, more importantly, into the poorly vascularized necrotic interiors which drugs are normally unable to penetrate. The nanoparticles have a number of advantages: less toxicity due to selective accumulation only in the tumors; access into the poorly vascularized necrotic interiors of the tumor; and sustained release over a period of time within the tumor.

  • Patent number: 9663565
    Abstract: The present invention relates to an insulinotropic peptide derivative with a modified N-terminal charge and a pharmaceutical composition including the same. Specifically, the insulinotropic peptide derivative is characterized in that the N-terminal positive charge of the insulinotropic peptide is modified to a neutral or net negative charge at neutral pH. The insulinotropic peptide derivative according to the present invention is rapidly dissociated from the GLP-1 receptor owing to the above modification in the N-terminal charge, and exhibits enhanced insulinotropic ability and blood glucose-lowering activity compared to the native insulinotropic peptide while maintaining its stability in blood. Accordingly, the insulinotropic peptide derivative of the present invention is very useful for the treatment of type 2 diabetes.

  • Patent number: 9629923
    Abstract: A CDDP complex is formed by complexation of CDDP and a polymer having a structure of Formula (I). The CDDP complex has good biocompatibility and is degradable. A side chain of the polymer is grafted with polyethylene glycol, which gives the CDDP complex good dissolvability. When dissolved in an aqueous medium, the CDDP is protected by a hydrophilic polyethylene glycol chain segment and a hydrophobic amino acid chain segment, which can effectively avoid a sudden release of the CDDP due to the influence of the blood circulation system after intravenous injection, thus improving the stability of the CDDP complex. A carboxyl group contained in the CDDP complex has pH value sensitivity and tends to be deprotonated in a low pH environment, which is advantageous for promoting the release of a drug, and improving the efficiency of the drug.

  • Patent number: 9040019
    Abstract: A method and a kit for detecting myelin basic protein are provided. The method comprises administering an agent, which binds to myelin basic protein (MBP), to a subject at risk of or diagnosed with a myelin-associated neuropathy, and determining myelination by detecting the agent resided in the subject. The amount of the agent present in the subject is indicative of a myelin-associated neuropathy. A method of quantifying an amount of MBP present in a tissue sample is also provided, wherein the method comprises contacting the tissue sample with the same agent, detecting the agent present in the tissue sample; and quantifying an amount of the agent present in the tissue sample.

  • Patent number: 9034298
    Abstract: 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 5 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.

  • Patent number: 9028800
    Abstract: The present application discloses compositions and methods of synthesis and use of 18F or 19F-labeled molecules of use in PET, SPECT and/or MR imaging. Preferably, the 18F or 19F is conjugated to a targeting molecule by formation of a complex with a group IIIA metal and binding of the complex to a bifunctional chelating agent, which may be directly or indirectly attached to the targeting molecule. In other embodiments, the 18F or 19F labeled moiety may comprise a targetable construct used in combination with a bispecific antibody to target a disease-associated antigen. The disclosed methods and compositions allow the simple and reproducible labeling of molecules at very high efficiency and specific activity in 30 minutes or less. In preferred embodiments, the labeled molecule may be used for imaging in a subject without purification after labeling.

  • Publication number: 20150125388
    Abstract: The invention relates to novel multi-modality probes for imaging, tracking and analyzing stem cells and related biological samples, and methods of preparation and use thereof. The molecular probes of the invention are constructed, for example, by utilizing (a) the high selectivity of long hydrocarbon chains for binding to plasma membranes of cells, (b) a near-infrared (NIR) dye for optical imaging, and (c) a radionuclide for PET or SPECT imaging. The in vitro and in vivo data of the optical and radiolabeled probes demonstrated their utility for detecting the presence of stem cells with multiple imaging modalities.
