Leupeptin hemisulfate is a protease inhibitor with cell membrane-permeable, reversible, competitive, and oral activities. Leupeptin hemisulfate inhibits the activity of Cathepsin B, Cathepsin H, and Cathepsin L, and blocks fusion of amphipathic lysosomes. Leupeptin hemisulfate also has anti-inflammatory activity.

Angiotensin II is a major biologically active vasoconstrictor peptide that regulates blood pressure by binding to AT1R and AT2R receptors. It stimulates the sympathetic nervous system, promotes aldosterone synthesis, and enhances renal function. Additionally, it induces vascular smooth muscle cell proliferation and increases collagen synthesis, leading to vascular and myocardial hypertrophy and fibrosis. It also promotes apoptosis and endothelial capillary formation. Angiotensin II is commonly used to induce hypertension and cardiac hypertrophy animal models.

Bombesin acetate is a 14-amino acid peptide originally isolated from the skin of the European fire-bellied toad (Bombina bombina). It has two known homologs in mammals called neuromedin B and gastrin-releasing peptide.

Leu-Leu-OH is a derivative dipeptide of leucine that can be used to study the function of the double leucine motif, is present as a metabolite in the human body, and is also detected in certain bacteria (e.g. Mycoplasma genitalium).

Gluten exorphin C is an opioid peptide derived from wheat gluten, with IC50 values of 40 μM for μ opioid and 13.5 μM for δ opioid activities in the GPI and MVD assays, respectively. Isolated from the pepsin-trypsin-chymotrypsin digest of wheat gluten, it is considered a δ-opioid receptor-selective ligand.
