  • 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%.

  • Deslorelin

    Deslorelin is a gonadotropin releasing hormone super-agonist (GnRH agonist) also known as an LHRH agonist. It stops the production of sex hormones (testosterone and oestrogen). It is currently approved for use in veterinary medicine and is used to induce ovulation in mares as part of the artificial insemination process. It is also used to stabilize high-risk pregnancies, mainly of livestock. Unlike other GnRH agonists, which are mainly used to inhibit luteinizing hormone and follicle-stimulating hormone by their ultimate downregulation of the pituitary gland.

  • Alarelin acetate

    Alarelin acetate is a synthetic LH-RH agonist, and stimulates the release of FSH and LH from the pituitary gland. It is known for its induction of ovulation and used to treat endmometriosis.

    Inquiry
  • 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.

  • Carperitide

    Atrial Natriuretic Peptide (ANP) (1-28), human, porcine is a 28-amino acid hormone, that is normally produced and secreted by the human heart in response to cardiac injury and mechanical stretch. ANP (1-28) inhibits endothelin-1 secretion in a dose-dependent way.

  • 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.

  • 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.

  • 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.

  • Somatostatin

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

  • 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.
