Angiotensin II

Angiotensin II human (Angiotensin II) is a vasoconstrictor that mainly acts on the AT1 receptor. Angiotensin II human stimulates sympathetic nervous stimulation, increases aldosterone biosynthesis and renal actions. Angiotensin II human induces growth of vascular smooth muscle cells, increases collagen type I and III synthesis in fibroblasts, leading to thickening of the vascular wall and myocardium, and fibrosis. Angiotensin II human also induces apoptosis.

Terlipressin

Terlipressin is a synthetic triglycyllysine derivative of vasopressin with vasoconstrictive, antihemorrhagic, and antidiuretic properties. Upon intravenous administration, terlipressin, an inactive prodrug, is biotransformed to its active moiety, lysine vasopressin (LVP), a nonselective vasopressin analogue with affinity for vasopressin receptors V1 (V1a), V2 and V3 (V1b). As a V1 agonist, terlipressin increases systemic vascular resistance, particularly in the splanchnic area, resulting in a decrease of portal pressure. V1 binding also promotes platelet aggregation and glycogenolysis, while V3 binding induces adrenocorticotropic hormone (ACTH) secretion. Compared to vasopressin, terlipressin has a minimal effect on V2 receptors, which are responsible for promotion of water reabsorption in the collecting ducts of the kidney via stimulation of cyclic AMP production.

Cetrorelix Acetate

Cetrorelix Acetate is a potent gonadotropin-releasing hormone (GnRH) receptor antagonist (IC50 = 1.21 nM). It can suppress production of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) from the pituitary gland which inhibits ovulation, exhibit antiproliferative effects and display efficacy against hormone-sensitive cancers in vivo. It is often used to treat hormone-sensitive cancers of the prostate and breast.

Terlipressin Acetate

Terlipressin acetate is a vasopressin analogue with potent vasoactive properties. Terlipressin acetate is a highly selective vasopressin V1 receptor agonist that reduces the splanchnic blood flow and portal pressure and controls acute variceal bleeding. Terlipressin acetate exerts anti-inflammatory and anti-oxidative effects. Terlipressin acetate has the potential for hepatorenal syndrome and norepinephrine-resistant septic shock research.

Abarelix

Abarelix is a synthetic decapeptide antagonist to gonadotropin releasing hormone (GnRH). It directly and competitively binds and blocks the gonadotropin releasing hormone receptors in the anterior pituitary, which inhibits the secretion and release of the luteinizing hormone (LH) and follicle stimulating hormone (FSH). For men, the inhibition of LH secretion prevents the release of testosterone. Therefore, it can relieve symptoms associated with prostate hypertrophy or prostate cancer.

Thymosin β4 Acetate

Thymosin β4 is a 43 amino acid peptide which is regarded as the main intracellular G-actin sequestering peptide. Extracellular thymosin β4 may contribute to physiological processes such as angiogenesis, wound healing and regulation of inflammation.

Icatibant

Icatibant (Firazyr) is a synthetic peptidomimetic drug consisting of ten amino acids, and acts as an effective and specific antagonist of bradykinin B2 receptors. It has been approved in the EU for use in hereditary angioedema, and is under investigation for a number of other conditions in which bradykinin is thought to play a significant role.

Aviptadil Acetate

Aviptadil, also known as vasoactive intestinal polypeptide (VIP), is a 28 amino acid neuropeptide that belongs to the glucagon-growth hormone-releasing factor secretion superfamily. Aviptadil acts as a potent systemic vasodilator and bronchodilator. It inhibits the proliferation of vascular and bronchial smooth muscle cells and decreases platelet aggregation. These biological effects are mediated by specific VIP receptors.

Exenatide Acetate

A 39-amino acid peptide originally isolated from the salivary glands of the Gila monster (Heloderma suspectum), differs from exendin-3 only in two positions close to the N-terminus. Application of exenatide causes an increase in acinar cAMP without stimulating amylase release. As an incretin mimetic, exenatide acts as agonist of the glucagon-like peptide-1 (GLP-1) receptor.

Pramlintide Acetate

Pramlintide acetate is a polypeptide analogue of human amylin. Pramlintide acetate, an antidiabetic agent, is antineoplastic in colorectal cancer.
