• Beschreibung

  IBMX (28822-58-4) is a pan-specific inhibitor of phosphodiesterases (IC50=2-50 μM). Inhibition of PDEs leads to increased concentration of intracellular cAMP which activates PKA.2?IBMX does not inhibit PDE8 or PDE9.3?Weak adenosine receptor antagonist.4

• Chemische Eigenschaften

  White Needles with Yellow Cast

• Verwenden

  3-Isobutyl-1-methylxanthine is used in inhibition of phenylephrine-induced release of 5-hydroxytryptamine from neuroendocrine epithelial cells of the airway mucosa (IC50 = 1.3 uM). Also inhibits ion channels in the neuromuscular junction, GH3 cells, and vascular smooth muscle cells. Inhibits the growth of carcinoma cells both in vivo and in vitro in mice.

• Verwenden

  phosphodiesterase inhibitor

• Verwenden

  A nonspecific inhibitor of phosphodiesterases

• Definition

  ChEBI: 3-isobutyl-1-methyl-9H-xanthine is a 3-isobutyl-1-methylxanthine. It is functionally related to a 9H-xanthine. It is a tautomer of a 3-isobutyl-1-methyl-7H-xanthine.

• Allgemeine Beschreibung

  3-isobutyl-1-methylxanthine/IBMX is a non-selective, non-specific inhibitor of cAMP and cGMP phosphodiesterases. IBMX can induce melanogenesis, and can be used as a positive control in melanogenesis research. In oocyte research, IBMX assists in maintaining the germinal vesicle (GV) arrest of prophase I oocytes.

• Biologische Aktivität

  Phosphodiesterase inhibitor (IC 50 values are 13, 18, 19, 32 and 50 μ M for PDE4, PDE3, PDE1, PDE5 and PDE2 respectively). Suppresses α -adrenoceptor-mediated 5-HT release from neuroendocrine epithelial cells (IC 50 = 1.3 μ M).

• Biochem/physiol Actions

  The increase in cAMP level as a result of phosphodiesterase inhibition by IBMX activates PKA, leading to decreased proliferation, increased differentiation, and induction of apoptosis. IBMX inhibits phenylephrine-induced release of 5-hydroxytryptamine from neuroendocrine epithelial cells of the airway mucosa (IC50: 1.3 μM). IBMX also serves as an adenosine receptor antagonist. IBMX has been shown to inhibit ion channels in the neuromuscular junction, GH3 cells, and vascular smooth muscle cells. IBMX induces calcium release from intracellular stores in sensory neurons.
