METHOD OF PREPARING A THIN FILM COMPOSITE LAYER
The present disclosure relates to a method of preparing a thin film composite layer immobilizing vesicles incorporating a transmembrane protein on a porous substrate membrane, comprising providing an aqueous solution comprising the vesicles and a di-amine or tri-amine compound, covering the surface of a porous support membrane with the aqueous solution, applying a hydrophobic solution comprising an acyl halide compound, and allowing the aqueous solution and the hydrophobic solution to perform an interfacial polymerization reaction to form the thin film composite layer.
Chitosan-pluronic complex and nano-carrier comprising same
The present invention relates to a transdermal nano-carrier and, more specifically, to a nano-carrier having a chitosan-based nano-sponge structure. According to the present invention, as a nano-carrier having enhanced transdermal delivery on the basis of a complex containing chitosan is provided, it is possible to effectively deliver drugs, cosmetic materials, etc. into the skin.
Methods & Systems for Controlled Release of Drug Cargo via ATP- Responsive Liposomes
Dimer and monomer molecules according to general formulas (I) or (II) are useful as lipid switch molecules when incorporated into a membrane of a liposome.
##STR00001##
wherein R.sup.1 is a hydrophobic tail having at least 6 carbons and wherein R.sup.2 is selected from the group consisting of —NH.sub.2,
##STR00002##
wherein, for the dimer, the linker is a saturated carbon chain having 2 to 6 carbons or is a para-xylene linker; and when R.sup.2 is charged anions are present to render the charge neutral. These molecules can bind ATP or similar small phosphorylated molecules between R.sup.2 groups, which changes the shape of the molecule or the molecules orientation within the membrane thereby acting as a “switch” to release a therapeutic agent from the liposome.
NANODRUG PARTICLES, THE USE THEREOF, AND PREPARATION METHOD THEREOF
A nanodrug particle includes alginate and a camptothecin compound. The camptothecin compound is grafted onto the alginate, and the alginate and the camptothecin compound self-assemble and form a nanosphere. The disclosure also provides a method for preparing a nanodrug particle; the method includes: modifying alginate to form alginate having amine groups; modifying a camptothecin compound to form a camptothecin compound having a carboxyl group; forming a camptothecin-alginate polymer by reacting the alginate having amine groups with the camptothecin compound having a carboxyl group, wherein the camptothecin-alginate polymer self-assembles in an aqueous solution and forms a nanosphere.
Nano composite material aiming at acidic sealing zone in osteoclasts and preparation method thereof
A nano composite material aiming at an acidic sealing zone in osteoclasts and a preparation method thereof are provided. The nano composite material aiming at the acidic sealing zone in the osteoclasts includes a nano material, bone-targeting molecules, and a compound able to react with the acidic sealing zone in the osteoclasts, wherein: after being modified by the bone-targeting molecules, the nano material is loaded with the compound able to react with the acidic sealing zone in the osteoclasts. Through accurate mature osteoclast targeting and chemically regulated biocascade effects, the osteoclasts are inhibited, which provides a new idea and a new tool for drug therapy of abnormal osteoclast activation.

Liposomic drug-delivery vehicles
A liposome for use in delivering a therapeutically active agent to a subject in need thereof is disclosed herein. The liposome comprises: a) at least one bilayer-forming lipid; b) a polymeric compound having the general formula I: ##STR00001## wherein m, n, L, X, Y, and Z are as defined herein; and c) a therapeutically active agent, incorporated in the liposome and/or on a surface of the liposome.
Compositions and Methods for Inducing Nanoparticle Mediated Microvascular Embolization of Tumors
Nanoparticle mediated microvascular embolization (NME) of tumor tissue may occur after systemic administration of PEM, leading to widespread shutdown of vascular flow, hemorrhage, and necrosis. PEM constructs are developed that incorporate large amounts of iron-containing protein, possess high oxygen affinities, and demonstrate delayed nitric oxide binding. Such properties induce selective NME of tumors after extravasation, and will likely enhance the effect of VEGFR TKIs and/or mTOR inhibitors.
