PYLa/PGLa precursor

Teriparatide Acetate

Teriparatide(recombinant human parathyroid hormone) /PTH (1-34) (human) corresponds to the N-terminal part of human parathyroid hormone, a peptide consisting of 84 amino acids.

Atosiban

Atosiban is a nonapeptide, desamino-oxytocin analogue, and a competitive vasopressin/oxytocin receptor antagonist (VOTra). Atosiban is indicated to delay imminent pre-term birth in pregnant adult women. Atosiban is useful in improving the pregnancy outcome of in vitro fertilization-embryo transfer (IVF-ET) in patients with repeated implantation failure (RIF). The pregnancy rate improved from zero to 43.7%.

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.

Angiotensin II Acetate

Angiotensin II is an octapeptide that produced from angiotensin I after the removal of two amino acids at the C-terminal by angiotensin-converting enzyme (ACE). Angiotensin II is mediated by AT1 and AT2 receptors, which are seven transmembrane glycoproteins with 30% sequence similarity.

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.

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.

GLP-1 (7-37) 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-2 as a gut hormone.

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.

Antide

Antide acetate (Ac-AA10-NH2) is an LHRH antagonist and represses LH and FSH release from the pituitary gland. It shows a high antiovulatory activity and releases negligible histamine.

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.
