Brain Natriuretic Peptide, Human

Brain natriuretic peptide, uretic peptide or Ventricular Natriuretic Peptide (still BNP), is a 32-amino acid polypeptide secreted by the ventricles of the heart in response to excessive stretching of heart muscle cells (cardiomyocytes). BNP is named as such because it was originally identified in extracts of porcine brain, although in humans it is produced mainly in the cardiac ventricles.

Labeling TargetAtrial natriuretic peptide receptor
ApplicationBrain natriuretic peptide (BNP) decreases the systemic vascular resistance and central venous pressure as well as increases the natriuresis. Thus, the net effect of BNP and atrial natriuretic peptide (ANP) is a decrease in blood volume, which lowers systemic blood pressure and afterload, yielding an increase in cardiac output, partly due to a higher ejection fraction.

Higher BNP concentrations early after first myocardial infarction are associated with adverse left ventricular remodelling characteristics. This may help explain why BNP is such a strong predictor of outcome after myocardial infarction.

Subtle cardiac abnormalities have been described in patients with cirrhosis. Natriuretic peptide hormones have been reported to be sensitive markers of early cardiac disease. We postulate that plasma levels of N-terminal pro-atrial natriuretic peptide and brain natriuretic peptide could be used as markers of cardiac dysfunction in cirrhosis.

  • 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.

  • 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.

  • 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%.

  • Somatostatin

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

  • 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.

  • 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
  • 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.

  • 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.
