Fármacos multifuncionais: monoamina oxidase e α-sinucleína como alvos terapêuticos na doença de Parkinson

Abstract: Recebido em 28/4/12; aceito em 7/8/12; publicado na web em 6/2/13 MULTIFUNCTIONAL DRUGS: MONOAMINE OXIDASE AND α-SYNUCLEIN AS TARGETS FOR THE TREATMENT OF PARKINSON´S DISEASE. Parkinson's disease (PD) is a neurodegenerative disorder associated to selective degeneration of dopaminergic neurons caused by an intricate relationship among dopamine metabolism, oxidative stress and a-synuclein fibrillation. Most therapies for PD have focused on dopamine replacement through the use of both monoamine oxidase inhibitors… Show more

“…The inhibition of MAO-B can prevent ROS formation from dopamine metabolism. Some studies have described a neuroprotective effect of this drug independent of its inhibitory action on MAO (Boll, Zubeldia, Rios, 2011;Follmer, 2013;Singh, Pillay, Choonara, 2007). Takahata et al (2006) described that selegiline can decrease oxidative stress in nigrostriatum by augmenting the antioxidant capacity, i.e., increasing the activity of antioxidant enzymes (superoxide dismutase and catalase) and the level of glutathione in specific brain regions.…”

“…Além disso, o extrato etanólico bruto das folhas de N. brasiliensis, coletadas no Estado do Rio de Janeiro, apresentou atividade inibitória antifúngica, por método de difusão, para Chalara paradoxa (De Seynes) Moreau, com halo de 12 mm (SALES et al, 2016). Fialho et al (2016), ao investigarem o extrato bruto etanólico das folhas e as frações diclorometano, acetato de etila e butanólica, constataram que o extrato bruto de N. brasiliensis apresentou o melhor efeito antiviral, in vitro, para o vírus da dengue (DENV)-2 e regulação negativa da secreção de TNF-α (tumor necrosis fator -Fator de necrose tumoral), IL-6 (interleucina 6), IL-10 (interleucina 10) e IFN-α (interferon alfa), carga viral antigênica celular e redução da proteína NS1 secretada (proteína não estrutural do vírus da dengue), enquanto a fração diclorometano apresentou um efeito imunomodulador no processo inflamatório e de sua ação nos neurônios pós-sinápticos (FOLLMER; BEZERRA NETTO, 2013;WHALEN;FINKEL;PANAVELIL, 2016).…”

“…Os autores incluem os antidepressivos tetracíclicos na classe dos ADTs, sendo que os mais famosos são a maprotilina e amoxapina. Os inibidores da enzima monoamina oxidase (IMAO) ligam-se covalentemente à enzima e a inativam, propiciando o aumento da concentração dessas monoaminas no corpo (Follmer & Bezerra Netto, 2013).…”
