meta-Tiramin

(Preusmjereno sa M-tiramin)

meta-Tiramin, poznat i kao m-tiramin i 3-tiramin, je endogeni amin u tragovima neuromodulator i strukturni analog fenetilamina.[1][2][3] To pozicijski izomer para -tiramina i, slično njemu, ima učinke na adrenergične i dopaminergične sisteme.[4][5]

Kod ljudi, meta-tiramin se proizvodi posredstvom metabolizma meta-tirozina uz katalizu enzimom dekarboksilaza aromatskih aminokiselina.[6] Također kod ljudi, ovaj spoj može se metabolizirati i u dopamin, preko perifernog ili moždanog CYP2D6 enzima.[7]
