MDL-72274 HCl CAS 85278-24-6 is selective and potent inhibitors of SSAO for treatment of Parkinson diseases. MDL-72974 is a potent (IC50 = 10(-9) M) inhibitor of both MAO-B and SSAO, with 190-fold lower affinity for MAO-A. In clinical studies, oral doses as low as 100 micrograms produced substantial inhibition of platelet MAO-B. One or 4 mg MDL-72274 HCl given daily for 28 days to 40 Parkinson's patients treated with L-dopa produced statistically significant reductions in the Unified Parkinson's Disease Rating Scale. MAO-B inhibitors, such as MDL 72974A and L-deprenyl, offer the potential of being neuroprotective in Parkinson's Disease and other neurogenerative disorders
