STh, also known as Escherichia coli heat-stable toxin, is a 19 amino acid polypeptide containing three disulfide bridges. It serves as an antigen of significance in the quest for a comprehensive enterotoxigenic Escherichia coli (ETEC) vaccine.

Matrixyl Acetate(214047-00-4 free base) (Palmitoyl pentapeptide) is a matrikine used in anti-wrinkle cosmetics.

Angiopeptin is a synthetic octapeptide analog of somatostatin; suppresses accelerated transplant atherosclerosis in rabbit heart arteries.

Felypressin (Octapressin) is a synthetic analog of LYPRESSIN with a PHENYLALANINE substitution at residue 2. Felypressin is a vasoconstrictor with reduced antidiuretic activity.

Felypressin acetate (PLV-2) is an agonist of vasopressin 1 and acts on all arginine vasopressin receptors 1AS. Felypressin acetate can be used in dental procedures.

st-Ht31, a cell-permeable stearated peptide derived from the amphipathic helix domain of A-kinase anchoring proteins (AKAPs), effectively binds protein kinase A (PKA), impacting PKA's cellular interactions without altering its activity. Specifically, at a 50 µM concentration, it reduces PKA's membrane anchoring in BHK-21 fibroblast reporter assays. Moreover, st-Ht31 at concentrations of 1 and 3 µM decreases both capacitance and hyperactivation in mouse sperm, thereby inhibiting in vitro fertilization. Additionally, at 50 µM, this compound facilitates cholesterol export in BHK-21 cells and RAW 264.7 macrophages expressing ATP-binding cassette transporter 1 (ABCA1), showcasing its multifaceted cellular impacts.

Stearated form of the peptide Ht-31. Inhibits the interaction between the RII subunits of cAMP-dependent PKA and A-kinase anchoring protein (AKAP) in cell extracts. Cell permeable.

Lys-arg-ala-lys-ala-lys-thr-thr-lys-lys-arg is a protein kinase C substrate.
