描述:
IBMX
Crystalline
Inhibits cyclic-AMP phosphodiesterase.
Ref.: 1. Beavo, J.A., et al., Molec. Pharmacol., 6: 597, (1970). 2. Montague, W. and Cook, J.R., Biochem. J., 122: 115, (1971).
Description: IBMX has been shown to be a potent, non-specific inhibitor of adenosine 3',5'-cyclic monophosphate phosphodiesterase (cAMP PDE)4, significantly more effective than theophylline.1,2,14,15,21 Also inhibits cGMP phosphodiesterases. IBMX inhibits cyclic nucleotide PDE with subsequent inhibition of cyclic nucleotide hydrolysis, resulting in accumulation of cyclic AMP and guanosine 3',5'-cyclic monophosphate.11,20 In a study of cyclic AMP and insulin release by islets of Langerhans, IBMX at 1 mM caused a marked increase in the intracellular concentration of cyclic AMP in the presence of glucose.14
IBMX, when used at 0.05 mM, was 20-fold more effective than theophylline at stimulating lipolysis in fat cells.2 It has been shown to promote the conversion of fibroblast cells into adipose cells, apparently without altering the amount of bromodeoxyuridine (BrdU) present in the DNA of the cells.16
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.5,7,18
Other actions of IBMX:
-
-
Inhibition of phenylephrine-induced release of 5-hydroxytryptamine from neuroendocrine epithelial cells of the airway mucosa (IC50 = 1.3 uM).9
-
An adenosine receptor antagonist.7,12
-
Inhibits ion channels in the neuromuscular junction, GH3 cells, and vascular smooth muscle cells.8
-
Inhibits the growth of carcinoma cells both in vivo and in vitro in mice.10
3-异丁基-1-甲基黄嘌呤
用途: cAMP 和 cGMP 磷酸二脂酶的非专一性抑制剂。IBMX抑制了磷酸二脂酶,cAMP的增加激活了PKA ,其结果是减少增殖,增加分化和诱发凋亡。 IBMX抑制由苯肾上腺素诱导的色胺(来自于神经内分泌上皮细胞的减少粘液IC50: 1.3 μM)的减少 。也作为腺苷受体拮抗剂。
