摘要:
The present invention provides processes for the production of preformed albumin conjugates. In particular, the invention provides processes for the in-vitro conjugation of a therapeutic compound to recombinant albumin, wherein a therapeutic compound comprising a reactive group is contacted to recombinant albumin in solution to form a conjugate. The processes provide for conjugation to albumin species of increasing homogeneity. The resulting conjugate is purified by chromatography, in particular hydrophobic interaction chromatography comprising phenyl sepharose and butyl sepharose chromatography.
摘要:
The present invention relates to a method for separating albumin conjugate from unconjugated albumin in a solution comprising albumin conjugate and unconjugated albumin by loading the solution onto a hydrophobic support equilibrated in aqueous buffer having a high salt content; applying to the support a gradient of decreasing salt concentration; and collecting the eluted albumin conjugate.
摘要:
The present invention relates to C34 peptide derivatives that are inhibitors of viral infection and/or exhibit antifusogenic properties. In particular, this invention relates to C34 derivatives having inhibiting activity against human immunodeficiency virus (HIV), respiratory syncytial virus (RSV), human parainfluenza virus (HPV), measles virus (MeV), and simian immunodeficiency virus (SIV) with long duration of action for the treatment of the respective viral infections.
摘要:
The present application relates to a compound having a formula 1: B—R1-R2-M wherein B is a binding element for recognizing and binding a target; R1 is a first group of atoms for reacting with a functionality of the target so as to form a covalent bond with the target; R2 is a second group of atoms; R1 and R2 being such that the formation of the covalent bond between R1 and the target generates cleavage of the bond between R1 and R2 so as to free R2-M; and M is selected from the group consisting of a hydrogen atom and a pharmaceutically acceptable moiety. Alternatively, R1 and R2 can be inverted to form the formula II: B—R2-R1-M and being such that the formation of the covalent bond between R1 and the target generates cleavage of the bond between R1 and R2 so as to free R2-B.
摘要:
Modified insulinotropic peptides are disclosed. The modified insulinotropic peptides are capable of forming a peptidase stabilized insulinotropic peptide. The modified insulinotropic peptides are capable of forming covalent bonds with one or more blood components to form a conjugate. The conjugates may be formed in vivo or ex vivo. The modified peptides are administered to treat humans with diabetes and other related diseases.
