KD and Bmax values for 3H-Ro 41-1049 in rat cerebral cortex were 10.7 nM and 7.38 pmol/mg protein, respectively, and for 3H-Ro 19-6327 were 18.4 nM and 3.45 pmol/mg protein, respectively [1]. The IC50 values for lazabemide and Ro 16-6491, respectively, were: 86 microM and 90 microM for NA uptake; 123 microM and 90 microM for 5HT uptake; > 500 microM and > 1000 microM for DA uptake. Lazabemide and Ro 16-6491 also differed from L-deprenyl in their ability to induce release of endogenous monoamines from synaptosomes. Thus, Ro 16-6491 (500 microM) induced a greater 5 HT release than did L-deprenyl, but was less effective than L-deprenyl in releasing DA. On the contrary, lazabemide was almost completely inactive on either 5 HT and DA release [2]. a clear inhibition of DOPAC formation was observed with Ro 41-1049 (250 nM), while 250 nM lazabemide was found not to increase the accumulation of newly-formed DA in those tubular epithelial cells loaded with 50 microM L-DOPA [3].in vivo: The ischemia reperfusion-induced hydroxyl radical generation was attenuated by 3 mg/kg of clorgyline and lazabemide. Furthermore, mice pretreated with these MAO inhibitors showed decreased DOPAC levels in comparison with those of their respective vehicle-treated control groups; recovery of the reduced DOPAC level was also delayed [4].
