产品名称
Ro 19-6327 hydrochloride
产品介绍
Lazabemide hydrochloride (Ro 19-6327 hydrochloride) 是单胺氧化酶 B (MAO-B) 的选择性的可逆抑制剂(IC50=0.03 μM),但对 MAO-A (IC50>100 μM) 活性较低。高浓度 Lazabemide 具有抑制单胺摄取的作用,抑制去甲肾上腺素、血清素和多巴胺摄取的 IC50值分别为 86 μM、123 μM 和 >500 μM。Lazabemide 可用于帕金森和阿尔茨海默病的研究。
生物活性

Lazabemide hydrochloride (Ro 19-6327 hydrochloride) is a selective, reversible inhibitor ofmonoamine oxidaseB (MAO-B)(IC50=0.03 μM) but less active forMAO-A(IC50>100 μM). Lazabemide inhibits monoamine uptake at high concentrations, the IC50values are 86 μM, 123 μM and >500 μM for noradrenalin, serotonin and dopamine uptake, respectively. Lazabemide can be used for the research of parkinson and alzheimer′s disease[1].

IC50& Target[1]

MAO-B

0.4 nM (IC50)

体外研究
(In Vitro)

The in vitro binding characteristics of both radiolabeled inhibitors revealed them to be selective, high-affinity ligands for the respective enzymes. KDand Bmaxvalues for3H-Ro 19-6327 in rat cerebral cortex are 18.4 nM and 3.45 pmol/mg protein, respectively[1].
The IC50values for lazabemide are: 86 μM for NA uptake; 123 μM for 5HT uptake; >500 μM for DA uptake, respectively[1].
. Lazabemide (5 μM) inhibits human MAO-B and MAO-A with IC50of 6.9 nM and >10 nM, respectively. And it inhibits rat MAO-B and MAO-A with IC50of 37 nM and >10 μM, respectively ina enzymatic assay[2].
Lazabemide differs from L-deprenyl in their ability to induce release of endogenous monoamines from synaptosomes. Thus, Lazabemide (500 μM) induces a greater 5 HT release than does L-deprenyl, but is less effective than L-deprenyl in releasing DA. On the contrary, lazabemide was almost completely inactive on either 5 HT and DA release[2].
Lazabemide (250 nM) results in a clear inhibition of DOPAC formation, while does not increase the accumulation of newly-formed DA in those tubular epithelial cells loaded with 50 microM L-DOPA[3].

体内研究
(In Vivo)

Lazabemide (3 mg/kg) attenuates ichemia reperfusion-induced hydroxyl radical generation and pretreatment with Lazabemide showed decreased DOPAC levels in comparison with those of their respective vehicle-treated control groups[4].
