    摘要: The present invention relates to a compound comprising a PYY peptide or a functional derivative thereof, which is coupled to a reactive group. Such a reactive group is capable of reacting on a blood component so as to form a stable covalent bond therewith. The present invention also relates to a conjugate comprising such a compound which is covalently bonded to a blood component. Moreover, the invention also relates to a method of enhancing, in a patient, the anti-obesity activity of a PYY peptide or functional derivative thereof.

    摘要: A method for protecting a peptide from peptidase activity in vivo, the peptide being composed of between 2 and 50 amino acids and having a C-terminus and an N-terminus and a C-terminus amino acid and an N-terminus amino acid is described. In the first step of the method, the peptide is modified by attaching a reactive group to the C-terminus amino acid, to the N-terminus amino acid, or to an amino acid located between the N-terminus and the C-terminus, such that the modified peptide is capable of forming a covalent bond in vivo with a reactive functionality on a blood component. In the next step, a covalent bond is formed between the reactive group and a reactive functionality on a blood component to form a peptide-blood component conjugate, thereby protecting said peptide from peptidase activity. The final step of the method involves the analyzing of the stability of the peptide-blood component conjugate to assess the protection of the peptide from peptidase activity.
