Method for cleavage of solid phase-bound peptides from the solid phase

The invention relates to a method for the cleavage of a solid phase-bound polypeptide from the solid phase, the method comprising contacting the solid phase, to which the polypeptide is bound, with a composition consisting essentially of trifluoroacetic acid and 1,2-ethanedithiol, at a temperature in the range of about 23° C. to about 29° C.

Method for producing dual function proteins and its derivatives

A method for producing a dual function protein includes a biologically active protein and an FGF21 mutant protein. The method allows stable production of a target protein by effectively preventing decomposition of the target protein, and thus has a high potential for commercial usage.

GLYCOPEPTIDE ANALOGS OF SECRETIN FAMILY PEPTIDES

Glycopeptide analogs of secretin family peptides, including PACAP and VIP, are described herein. These glycopeptides analogs can have neuroprotective properties and enhanced ability to cross the blood brain barrier (BBB) and/or enhanced stability. These glycosylated peptides can be used as drugs for treatment of CNS disorders, such as Parkinson's disease.

PEPTIDES COMPRISING NON-NATURAL AMINO ACIDS AND METHODS OF MAKING AND USING THE SAME
20230080520 · 2023-03-16 ·

This invention relates to novel compositions comprising analogs of naturally occurring polypeptides, wherein the analog comprises an α-amino acid and at least one β-amino acid. Administration of the compositions may be used for effecting treatment or prevention of a plurality of disease states caused by dysfunctional biochemical or biological pathways. The compositions and methods of this invention are particularly useful to identify novel therapeutic modulators of in-vivo receptor activity with extended half-lives and relevant bioactivity as compared to the naturally translated polypeptides upon which the analogs are derived.

PEPTIDE IMMUNOGENS TARGETING PITUITARY ADENYLATE CYCLASE-ACTIVATING PEPTIDE (PACAP) AND FORMULATIONS THEREOF FOR PREVENTION AND TREATMENT OF MIGRAINE
20230146694 · 2023-05-11 ·

The present disclosure is directed to peptide immunogen constructs targeting portions of Pituitary adenylate cyclase-activating polypeptide (PACAP), compositions containing the constructs, antibodies elicited by the constructs, and methods for making and using the constructs and compositions thereof. The disclosed peptide immunogen constructs have more than about 20 amino acids and contain (a) a B cell epitope having about more than about 9 contiguous amino acid residues from the PACAP receptor binding or activation regions of the full-length PACAP protein; (b) a heterologous Th epitope; and (c) an optional heterologous spacer. The disclosed PACAP peptide immunogen constructs stimulate the generation of highly specific antibodies directed PACAP for the prevention and/or treatment of migraine.

Coiled coil immunoglobulin fusion proteins and compositions thereof

Disclosed herein are immunoglobulin fusion proteins comprising a first antibody region, a first therapeutic agent, and a first connecting peptide; wherein the first therapeutic agent is attached to the first antibody region by the connecting peptide; and wherein the connecting peptide does not comprise a region having beta strand secondary structure. The connecting peptide may comprise an extender peptide. The extender peptide may have an alpha helical secondary structure. The connecting peptide may comprise a linker peptide. The linker peptide may not comprise any secondary structure. Also disclosed herein are compositions comprising the immunoglobulin fusion proteins and methods for using the immunoglobulin fusion proteins for the treatment or prevention of a disease or condition in a subject.

Anti-PACAP antibodies

The present invention is directed to antagonistic antibodies and antigen binding fragments thereof having binding specificity for PACAP. These antibodies inhibit, block or neutralize at least one biological effect associated with PACAP, e.g., vasodilation. In exemplary embodiments these antibodies and antigen binding fragments thereof may comprise specific V.sub.H, V.sub.L, and CDR polypeptides described herein. In some embodiments these antibodies and antigen binding fragments thereof bind to and/or compete for binding to specific epitope(s) on human PACAP. The invention is further directed to using these antagonistic anti-PACAP antibodies, and binding fragments thereof, for the diagnosis, assessment, and treatment of diseases and disorders associated with PACAP and conditions where antagonism of PACAP-related activities, such as vasodilation, mast cell degranulation, and/or neuronal activation, are therapeutically beneficial, e.g., headache and migraine indications.
