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%.

Hot Products
  • 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.

    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.

    Inquiry
  • 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.

    Inquiry
  • 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.

    Inquiry
  • 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.

    Inquiry
  • Somatostatin

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

    Inquiry
  • 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.

    Inquiry
  • Buserelin Acetate

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

    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.
