GLP-1 (7-36) amide Acetate

Glucagon-like peptide-1 (GLP-1) is an incretin derived from the transcription product of the proglucagon gene. The major source of GLP-1 in the body is the intestinal L cell that secretes GLP-1 as a gut hormone. Its physiological functions include promoting insulin sensitivity, decreasing food intake by increasing satiety in brain and increasing insulin secretion from the pancreas in a glucose-dependent manner.

Fertirelin Acetate

Fertirelin 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.

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.

Octreotide Acetate

Octreotide is a somatostatin analog that binds to the somatostatin receptor, mainly subtypes 2, 3, and 5, increases Gi activity, and reduces intracellular cAMP production.

Bivalirudin

Bivalirudin, a peptide anticoagulant, is a direct thrombin inhibitor for anticoagulation in the setting of invasive cardiology, particularly percutaneous coronary intervention.

Exenatide

Exendin-4 (exenatide), 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. As GLP-1, though with prolonged activity, exenatide augments the postprandial production of insulin and suppresses secretion of glucagon. For this reason, exenatide has found use as a medication of diabetes II.

Glucagon

Glucagon (Porcine glucagon) is a peptide hormone, produced by pancreatic α-cells. Glucagon stimulates gluconeogenesis. Glucagon decreases the activity of HNF-4. Glucagon increases HNF4α phosphorylation.

Gonadorelin Acetate

Gonadorelin is a trophic peptide hormone responsible for the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary. GnRH is synthesized and released from GnRH neurons within the hypothalamus. The peptide belongs to gonadotropin-releasing hormone family. It constitutes the initial step in the hypothalamic–pituitary–gonadal axis.

Elcatonin Acetate

Elcatonin acetate inhibits the absorption and autolysis of bones, thus leads to blood calcium descending. In addition, it inhibits the bone salts dissolving and transferring and promotes the excretion of calcium and phosphorus in urine.

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.
