Pramlintide

Pramlintide is an analogue of amylin, a small peptide hormone that is released into the bloodstream by the β-cells of the pancreas along with insulin, after a meal. Like insulin, amylin is completely absent in individuals with Type I diabetes.

Nafarelin Acetate

Nafarelin acetate is a potent LHRH agonist. After a transient increase, continuous administration results in downregulation of LH and FSH levels followed by a suppression of ovarian and testicular steroid biosynthesis.

Enfuvirtide

Enfuvirtide is a 36 amino acid peptide corresponding to a region of gp41, the transmembrane subunit of HIV-1 envelope protein. It belongs to the therapeutic class of fusion inhibitors and acts by binding to gp41 and impeding the conformational changes in gp41 necessary for fusion of the virus with the cell.

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.

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.

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.

Thymopentin Acetate

Thymopentin, also known as TP-5, is a synthetic derivative of thymopoietin, a thymic hormone, and has immunoregulatory properties. Thymopentin interacts with T cells, reduces endocrine and behavioral responses to experimental stress. It is also found to increase the number of cells undergoing apoptosis in irradiated cells and selectively bind to apoptotic cells.

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.

Somatostatin

Somatostatin is a tetradecapeptide which can suppress the growth hormone (GH) secretion and control the pituitary hormone secretion in human CNS.

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.
