  • 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.

  • Carbetocin

    Carbetocin is a long-acting synthetic agonist analogue of human oxytocin, with antihemorrhagic and uterotonic activities. Upon administration, carbetocin targets, binds to and activates peripheral oxytocin receptors that are present on the smooth musculature of the uterus. This causes uterus contractions and prevents excessive bleeding after childbirth, particularly following Cesarean section, and may be used to decrease blood loss during hysteroscopic myomectomy.

    Inquiry
  • 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.

  • Teduglutide

    Teduglutide is a polypeptide consisting of 33 amino acids. It is glucagon-like peptide-2 (GLP-2) analogue that is used for the treatment of short bowel syndrome.

  • Buserelin Acetate

    Buserelin Acetate is an agonist of gonadotropin-releasing hormone receptor(GnRHR). Buserelin is a synthetic luteinizing hormone–releasing hormone (LHRH) analog.

  • 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.

    Inquiry
  • Argipressin

    Vasopressin, also known as arginine vasopressin (AVP), antidiuretic hormone (ADH), or argipressin, is a neurohypophysial hormone found in most mammals. Its two primary functions are to retain water in the body and to constrict blood vessels.

    Inquiry
  • 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.

    Inquiry
  • 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.
