Phalloidin, a bicyclic heptapeptide found in Gooseberry, is involved in F-actin staining. Phalloidin is a compound that irreversibly polymerizes actin into microfilaments.Phalloidin interferes with cell motility and growth, and can be used to label cerebral blood vessels.

Amyloid-Forming peptide GNNQQNY, a biologically active heptapeptide derived from the N-terminal prion-determining domain of yeast Sup35, is instrumental in amyloid fibril formation. Its atomic oligomeric structure has been detailed, serving as an excellent model for investigating early-stage aggregation. The peptide can form three stable β-sheet structures: in-register parallel, off-register parallel, and anti-parallel. Notably, the in-register parallel dimer aligns closely with amyloid β-sheet architecture, relying on fewer interpeptide hydrogen bonds and emphasizing hydrophobic interactions, which enhances conformational entropy relative to the anti-parallel arrangement.

Unguisin B is a cyclic heptapeptide originally isolated from the marine fungus E. unguis whose structure is comprised of amino acids and GABA.

Dermorphin is agonist of μ-opioid receptor (MOR) agonist.

Alamandine can be formed from angiotensin A by action of ACE-2 or directly from angiotensin-(1-7) by decarboxylation of its aspartate residue. The angiotensin A analog produces effects resembling those of Ang II (1-7). However, it acts independently of the two known vasodilators receptors of the RAS (Mas and angiotensin II type 2). To produce its effects, alamandine binds to the Mas-related receptor, MrgD. A novel orally active formulation of alamandine produced a long-term antihypertensive effect in spontaneously hypertensive rats and cardioprotective effects. These novel findings will be helpful for developing a new understanding of the RAS, a key regulator of blood pressure and fluid balance. The heptapeptide could serve as a model peptide, e.g. in the development and evaluation of analytical methods.

PapRIV, a quorum-sensing heptapeptide derived from B. cereus, undergoes synthesis as a 48-amino acid polypeptide. This compound is secreted and then extracellularly processed by NprB proteases into its active form. At concentrations ranging from 1-25 µM, PapRIV triggers the production of IL-6 and TNF-α, as well as NF-κB translocation, specifically in BV-2 microglia cells.

Super-tdu (1-31) TFA is an endogenous ligand of heptapeptide receptor and has a strong anti-analgesic effect.

Alexamorelin Met 1 is one of the metabolites of alexamorelin. The heptapeptide Ala-His-D-2-methyl-Trp-Ala-Trp-D-Phe-Lys-NH2 (Alexamorelin) is a synthetic molecule which inhibits growth hormone secretagogue binding in vitro.

Dermorphin Analog is an analog of Dermorphin. Dermorphin is a natural heptapeptide μ-opioid receptor agonist found in amphibian skin. The dermorphin-derived peptide [Dmt1] dermorphin analog labels m-opioid receptors with high affinity and selectivity in r

Eptifibatide (Eptifibatide Acetate), an antiplatelet drug of the glycoprotein IIb/IIIa inhibitor class, is a cyclic heptapeptide constructed from 6 amino acids and a mercaptopropionyl residue.

Lagatide is a synthetic heptapeptide that has antisecretory activity.

Substance P (5-11), the C-terminal heptapeptide derived from Substance P, functions as a neuropeptide. It specifically interacts with the NK-1 tachykinin receptor [1].

LH-RH (4-10), a heptapeptide, represents one of the primary degradation products of luteinising-hormone releasing hormone (LHRH), occurring through the pathways of the pituitary and hypothalamus. It is produced in macrophages and type II pneumocytes [1].

Angiotensin (1-7) (ASP-ARG-VAL-TYR-ILE-HIS-PRO) is a synthetic heptapeptide identical to endogenous angiotensin-(1-7) , inhibits purified canine ACE activity (IC50=0.65 μM) with vasodilator and antiproliferative activities.

Angiotensin 1-7 (Ang-(1-7)) acetate, an endogenous heptapeptide from the renin-angiotensin system (RAS), exhibits cardioprotective effects through its anti-inflammatory and anti-fibrotic activities in cardiac cells. It effectively inhibits purified canine ACE activity (IC 50 =0.65 μM) and serves as a local synergistic modulator of kinin-induced vasodilation by hindering ACE and facilitating nitric oxide release. Additionally, this compound prevents Ang II-induced proliferation and hypertrophy in smooth muscle cells, alongside demonstrating antiangiogenic and growth-inhibitory effects on the endothelium [1] [2] [3].
