The present invention is generally directed to core/shell nanoparticles, wherein such core/shell nanoparticles comprise a nanoparticle core and a nanoshell disposed about the nanoparticle core such that, in the aggregate, they form a core/shell nanoparticle that is operable for use as an imaging agent in X-ray/computed tomography (CT). Typically, such core/shell nanoparticle-based X-ray CT imaging agents further comprise a targeting species for targeting the imaging agent to diseased sites.

The invention provides an active targeting type amphipathic polypeptide nano-drug carrier and preparation and application thereof, and belongs to the technical field of biological medicines. According to an amphipathic polypeptide, an alkyl chain serves as the hydrophobic end, a polypeptide chain with active targeting functional and side chain modification fluorescent functional molecules serves as the hydrophilic end, and an anti-tumor drug is wrapped in a hydrophobic cavity of a micelle formed by self-assembling the amphipathic polypeptide. The nano-carrier can actively target tumor cells and enter the tumor cells through receptor-mediated endocytosis, the amphipathic polypeptide and phospholipid molecules have strong interaction, and the phagocytosis of a nano-drug by tumor cells is promoted. In the process, tracing can be conducted through fluorescent imaging of fluorescent functional molecules modified on the polypeptide chain, and the tumor imaging aim is realized. Finally, the anti-tumor drug is slowly released to kill tumor cells and restrain the growth of tumors. The amphipathic polypeptide nano-carrier is free of toxin, high in biocompatibility and remarkable in anti-tumor efficiency, and the tumor diagnosis and treatment can be integrated.

Typically, such core/shell nanoparticle-based X-ray CT imaging agents further comprise a targeting species for targeting the imaging agent to diseased sites. Included herein are methods for forming such agents, comprising forming an ensemble of core/shell nanoparticles, wherein the mean diameter of the ensemble of core/shell nanoparticles is selected so as to render the nanoparticles in the ensemble substantially clearable by a mammalian kidney.

The present invention relates to a long-acting single-chain insulin analog, a conjugate thereof, and uses of the same. In addition, the present invention relates to a method for preparing a long-acting single-chain insulin analog and a conjugate thereof.

The present invention relates to a pharmaceutical composition for the prevention and treatment of non-alcoholic fatty liver disease (NAFLD), including a conjugate prepared by covalently linking an insulinotropic peptide, a non-peptidyl polymer and an immunoglobulin Fc region. The composition of the present invention maintains the in-vivo activity of the peptide at a relatively high level, and remarkably increases the blood half-life, thereby preventing triglyceride accumulation which is a typical feature of non-alcoholic fatty liver disease. Ultimately, it can be desirably employed for the prevention and treatment of non-alcoholic fatty liver disease.

The present invention relates to a pharmaceutical composition for the prevention or treatment of non-alcoholic fatty liver disease including a long-acting GLP-1/glucagon receptor dual agonist, and a method for preventing or treatment of non-alcoholic fatty liver disease including administering the composition. The composition of the present invention either has no side effect of weight gain or reduces the side effect of weight gain, which is a side-effect of conventional therapeutic agents for non-alcoholic fatty liver disease, and reduces the amount of administrations of a long-acting GLP-1/glucagon receptor dual agonist, thus greatly improving patient's convenience. In addition, the long-acting GLP-1/glucagon receptor dual agonist of the present invention improves in vivo sustainability and stability.
