Conjugate for obesity treatment with oxyntomodulin and immunoglobulin
A recently granted patent (Publication Number: US11872283B2) discloses a novel conjugate designed for the treatment of obesity. The conjugate comprises an oxyntomodulin derivative with specific amino acid sequences, an immunoglobulin Fc region, and a non-peptidyl polymer that links the two components via covalent bonds. The oxyntomodulin derivative in the conjugate is capable of activating glucagon-like peptide-1 receptor, glucagon receptor, or both, thereby exhibiting anti-obesity effects. The non-peptidyl polymer used in the conjugate includes options such as polyethylene glycol, polysaccharides like dextran, and other polymers like hyaluronic acid.
Furthermore, the patent claims cover various aspects of the conjugate, including the specific amino acid sequences of the oxyntomodulin derivative, the types of non-peptidyl polymers that can be used, and the methods of preparing the conjugate. The patent also extends to pharmaceutical compositions containing the conjugate along with a pharmaceutically acceptable carrier. Additionally, methods for treating obesity using the conjugate, either alone or in combination with other specified agents like receptor agonists and enzyme inhibitors, are also included in the patent claims. This innovative approach to combating obesity through a unique conjugate opens up new possibilities for therapeutic interventions in this prevalent health condition.
