The present disclosure provides recombinantly manufactured ultra-long acting insulin-Fe fusion proteins for use in treating canine and feline diabetes. The insulin-Fe fusion proteins comprise an insulin polypeptide linked via a peptide linker to an Fe-fragment of canine or feline origin. Based on the results obtained, creating a treatment that is amenable to low cost manufacturing, exhibits sufficient in vivo bioactivity, displays extended duration of bioactivity, does not induce anti-dmg antibodies, and substantially retains is potency over multiple administrations, requires a non-obvious com- bination of insulin polypeptide, peptide linkers, and species-specific Fe fragment, in addition to selective mutations on one or more of these components. Exemplary ultra-long acting insulin-Fe fusion proteins, polynucleotides encoding these insulin-Fe fusion proteins, and pharmaceutical formulations of exemplary insulin-Fe fusion proteins are provided, in addition to methods of use and preparation. 20 24 28 71 86 23 D ec 2 02 4 1 0 0 5 6 8 8 4 5 4 A B S T R A C T 2 0 2 4 2 8 7 1 8 6 2 3 D e c 2 0 2 4

This disclosure provides a recombinantly prepared ultralong-acting insulin-Fc fusion protein for the treatment of diabetes. The insulin-Fc fusion protein comprises an insulin polypeptide linked to a human Fc fragment via a peptide linker. Based on the results obtained, a therapeutically appropriate combination of insulin polypeptide, peptide linker, and Fc fragment, exhibiting adequate in vivo biological activity, demonstrating an extended duration of biological activity, and not exhibiting immunogenicity, is created, requiring a non-obvious combination of these components, including the insulin polypeptide, peptide linker, and Fc fragment, and selective mutations in one or more of these components. In addition to the uses and methods of preparation, exemplary ultralong-acting insulin-Fc fusion proteins, polynucleotides encoding these insulin-Fc fusion proteins, and pharmaceutical formulations of exemplary insulin-Fc fusion proteins are also provided.

Providing modified insulin and glucokinase nucleic acids for treating diabetes SOLUTION: Reducing hyperglycaemia and maintaining euglycaemia are the goals of all therapeutic approaches to the T1DM and T2DM. Current therapy for most diabetics is based on regular subcutaneous injections of both short-acting and long-acting insulin preparations. The present disclosure relates to modified nucleic acid sequences encoding insulin and glucokinase, expression cassettes and delivery vectors comprising the same, and methods for their delivery to treat diabetes.SELECTED DRAWING: None

A liquid composition comprising a GLP-1 agonist or / and a pharmacologically tolerable salt thereof and, optionally, at least one pharmaceutically acceptable excipient, wherein the composition comprises methionine, as add-on therapy with metformin and / or with long-acting insulin / insulin derivates where appropriate.

The application relates to an aqueous pharmaceutical formulation comprising 200-1000 U / mL [equimolar to 200-1000 IU human insulin] of insulin glargine.

This invention relates to the field of cell culture technology, and more particularly to a culture medium additive for mesenchymal stem cells and its application. The culture medium additive of this invention, using water as a solvent, comprises the following components at the following concentrations: 0.5-1.5 mg / L rhTXNDC5 protein, 10-20 mg / L vascular endothelial cadherin 5, 10-20 mg / L vascular endothelial cadherin 11, 10-20 mg / L recombinant human long-acting insulin-like growth factor-1, 400-600 mg / L dextran, 200-400 mg / L riboflavin, 300-500 IU / L superoxide dismutase, 10-20 mg / L ethanolamine, and 1-3 mg / L progesterone. Adding this culture medium additive to serum-free culture medium can increase the yield of mesenchymal stem cells and accelerate the emergence time of umbilical cord mesenchymal stem cells.

The application discloses an amphoteric ion polymer-insulin conjugate and a preparation method and application thereof. 2-bromoisobutyric acid N-hydroxysuccinimide ester is reacted with INS to introduce an ATRP reaction site at the Lys B29 position of the INS, so that INS-Br is obtained; the INS-Br, MPC and a catalyst are mixed, deoxygenated, CuBr is further mixed, and full polymerization reaction is carried out, so that CuBr and PMDETA are used as a catalytic system, INS-Br is used to initiate polymerization of the amphoteric ion monomer MPC, and through dialysis and cation chromatographic column purification technology, INS-PMPC is obtained. Compared with INS and INS-PEG, the INS-PMPC has a longer blood glucose control time under the same dose, and can significantly reduce the risk of hypoglycemia, has high stability under room temperature and mechanical stirring, is resistant to storage, is suitable for areas where cold chain facilities are lacking, and is a long-acting insulin drug with higher safety.

The invention relates to a preparation method of amino acid selectively protected Fmoc-His (Mmt) containing side chain amino groups, and belongs to the technical field of polypeptide synthesis. The preparation method comprises the following steps: protecting carboxyl of amino acid, a main chain and amino groups of side chains, removing under specific conditions to obtain a corresponding product with protected amino groups of the side chains, and protecting amino groups of the main chain to realize synthesis of the high-purity histidine derivative. According to the method, the total yield can reach 78%, the product purity is larger than 99.8%, the chiral integrity is larger than 99.95%, the COD value of process wastewater is reduced by 62% compared with that of a traditional method, and the method is suitable for industrial production of polypeptide drugs such as long-acting insulin analogues. The amino acid preparation method provided by the invention is also suitable for lysine / histidine / ornithine / 2.3-diaminopropionic acid / tryptophan and the like.

The present disclosure provides methods for lowering the blood glucose of a target subject, including for treating diabetes, by administering recombinantly manufactured ultra-long acting insulin-Fc fusion proteins.

The present invention provides long-acting insulin-Fc fusion proteins, which have reduced insulin receptor affinity, increased growth factor receptor selectivity, and a prolonged half-life in the body, which can extend the duration of blood glucose reduction in the body, shorten the interval between insulin doses, and reduce side effects such as the risk of hypoglycemia.
