Mofegiline Hcl (MDL72974A) is a potent and selective enzyme-activated irreversible inhibitor of MAO-B; shows marked selectivity for the B form (IC50 = 680 and 3.6 nM for MAO-A and MAO-B).IC50 value: 3.6 nM [1]Target: MAO-Bin vitro: MDL72974 inhibits rat brain mitochondrial MAO in a concentration and time-dependent fashion and shows marked selectivity for the B form (IC50 = 680 and 3.6 nM for MAO-A and MAO-B, respectively) [1]. is also capable of inhibiting semicarbazide-sensitive amine oxidases (SSAOs) obtained from vascular tissues and sera of different species. The inhibition of SSAO by MDL-72974A was irreversible and time dependent. It was competitive without preincubation of the enzyme with the inhibitor and demonstrated a mixed-type of inhibition when the enzyme was preincubated with the inhibitor. The IC50 values were estimated to be 2 x 10(-9) M, 5 x 10(-9) M, 8 x 10(-8) M and 2 x 10(-8) M for SSAO from dog aorta, rat aorta, bovine aorta and human umbilical artery, respectively [2]. in vivo: After oral administration to rats, the compound shows preferential inhibition of brain MAO-B with ED50 values of 8 and 0.18 mg/kg p.o. for the A and B forms, respectively. Selectivity is retained on repeat dosing. MDL 72,974 did not significantly potentiate the cardiovascular effects of intraduodenually-administered tyramine in anaesthetized rats and had only minor indirect sympathomimatic effects in the pithed rat [1]. Male beagle dogs were given single p.o. (20 mg/kg) and i.v. (5 mg/kg) doses of [14C]-Mofegiline. Total radioactivity excreted in urine and feces over 96 hr was, respectively, 75.5 +/- 3.8 and 6.3 +/- 3.4% of the dose after p.o. and 67.9 +/- 0.5 and 3.9 +/- 2.4% after i.v. administration. Unchanged drug in urine represented 3% of the dose after po and less than 1% after i.v. administration. Mofegiline was thus extensively metabolized in dogs, and urinary excretion was the major route of elimination of metabolites [3].

Ro 41-1049 hydrochloride is a selective, reversible, orally-active MAO-A inhibitor.Target: MAOin vivo: Ro 41-1049 is an inhibitor of the enzyme monoamine oxidase type A (MAO-A) to rats and monitored extracellular catecholamine levels in the corpus striatum before and after the intraperitoneal (IP) administration of a bolus of L-dopa. Acute administration of Ro 41-1049 (1-50 mg/kg IP) produced a dose-dependent decrease in basal levels of the dopamine metabolites 3,4-dihydroxyphenylacetic acid (DOPAC) and homovanillic acid (HVA) and an increase in basal levels of dopamine. In rats treated with Ro 41-1049 (20 mg/kg IP), L-dopa administration (100 mg/kg IP) produced a greater increase in striatal levels of dopamine than it did in controls, while DOPAC and HVA formation was attenuated. We conclude that inhibition of central MAO-A activity promotes synaptic accumulation of dopamine following administration of pharmacological doses of L-dopa.

Rasagiline Mesylate is a new MAO-B inhibitor for the treatment of idiopathic Parkinson's disease. Target: Monoamine Oxidase (MAO)-BRasagiline (N-propargyl-1-(R)-aminoindan) is a novel, highly potent irreversible monoamine oxidase (MAO)-B inhibitor, anti-Parkinsonian drug. Rasagiline is effective as monotherapy or adjunct to L-Dopa for patients with early and late Parkinson's disease (PD) [1]. Rasagiline inhibits MAO-B more potently than selegiline and has the advantage of once-daily dosing. In several large, randomized, placebo-controlled trials, rasagiline has demonstrated efficacy as monotherapy in early PD and as adjunctive therapy in advanced PD. In addition, rasagiline has been shown to have neuroprotective effects in in vitro and in vivo studies. The recently completed delayed-start ADAGIO (Attenuation of Disease Progression with Azilect Given Once-daily) trial suggests a potential disease-modifying effect for rasagiline 1 mg/day, though the clinical import of this finding has yet to be established [2]. Rasagiline has been found to be well tolerated and effective in the treatment of early PD and as adjunctive treatment in motor fluctuations. Whether rasagiline is associated with clinically significant neuroprotection (ie, disease modification) in PD is the subject of ongoing clinical trials [3].
