KD and Bmax values for 3H-Ro 19-6327 in rat cerebral cortex are 18.4 nM and 3.45 pmol/mg protein, respectively. The IC50 values for lazabemide are: 86μM for NA uptake; 123μM for 5HT uptake; > 500μM for DA uptake, respectively. Lazabemide (5μM) inhibits human MAO-B and MAO-A with IC50 of 6.9nM and >10nM, respectively. And it inhibits rat MAO-B and MAO-A with IC50of 37nM and >10μM, respectively ina enzymatic assay. Lazabemide differs from L-deprenyl in their ability to induce release of endogenous monoamines from synaptosomes. Thus, Lazabemide (500μM) 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. Lazabemide (250nM) results in a clear inhibition of DOPAC formation, while does not increase the accumulation of newlyformed DA in those tubular epithelial cells loaded with 50microM L-DOPA. 体内研究 Lazabemide (3mg/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.
