Process for the manufacture of degarelix and its intermediates

The present invention relates to a liquid (or solution)-phase manufacturing process for preparing the decapeptide Degarelix, its protected precursor, and other useful intermediates. The invention further relates to polypeptides useful in the solution-phase manufacturing process and to the purification of Degarelix itself. Degarelix can be obtained by subjecting a Degarelix precursor according to formula II: (P.sub.1)AA.sub.1-AA.sub.2-AA.sub.3-AA.sub.4(P.sub.4)-AA.sub.5-AA.sub.6(P.sub.6)-AA.sub.7-AA.sub.8(P.sub.8)-AA.sub.9-AA.sub.10-NH.sub.2 (II) or a salt or solvate thereof, to a treatment with a cleaving agent in an organic solvent, wherein P.sub.1 is an amino protecting groups; preferably acetyl; P.sub.4 is hydrogen or a hydroxyl protecting group, preferably a hydroxyl protecting group; P.sub.6 is hydrogen or an amino protecting groups; preferably an amino protecting groups; and P.sub.8 is an amino protecting group.

METHOD FOR ENHANCING EXTRACELLULAR VESICLE PRODUCTION
20170233766 · 2017-08-17 ·

A method for enhancing extracellular vesicle production is described. A peptide that induces polymer formation is incubated with a cell culture which results in enhanced EV production. The peptide penetrates the cells and subsequently polymerizes upon exposure to enzymes (e.g. phosphatase) within the cell. The cells that contain the newly formed polymers have an increased production of EVs. These EVs can be harvested using centrifugation techniques.

20220267372 · 2022-08-25 ·

Peptide-based compounds including heteroatom-containing, three-membered rings efficiently and selectively inhibit specific activities of N-terminal nucleophile (Nn) hydrolases. The activities of those Ntn having multiple activities can be differentially inhibited by the compounds described. For example, the chymotrypsin-like activity of the 20S proteasome may be selectively inhibited with the inventive compounds. The peptide-based compounds include an epoxide or aziridine, and functionalization at the N-terminus. Among other therapeutic utilities, the peptide-based compounds are expected to display anti-inflammatory properties and inhibition of cell proliferation.
