Monoaminorum oxidasis B

Monoamini oxydasis B

Monoaminorum oxidasis B (abbreviatura MAO-B) est unum ex duobus isoenzymis monoaminorum oxidasis (OMIM: 309860). Nomen chromosomate X locati geni est MAOB.

Natura MAO-BRecensere

Genum MAOB in chromosomate X (Xp11.3) locatum est. In cerebro humano MAO-B praecipue in cellulis nervorum systematis serotonergici atque nucleis raphes (et dorsalibus et medianis) inventum est[1]. Enzymum MAO-B in thrombocytis quoque exprimuntur.

Effectus MAO-BRecensere

Enzym hoc decompositionem dopamini perficit. Inhibito igitur enzymi multitudinem dopamini augeat.

Inhibitores MAO-BRecensere

Inhibitores sunt Rasagilinum, Safinamidum[2], Selegilinum. Fumatio quoque MAO-B inhibit[3].

Medicamentum
Rasagilinum 3 h
Selegilinum 10 h
Safinamidum 20-30 h
