Biochem/physiol Actions
1-Methyl-1,2,3,4-tetrahydroisoquinoline (1MeTIQ) is an endogenous antidepressant and parkinsonism-preventing substance that demonstrates neuroprotectiveactivity.
1-Methyl-1,2,3,4-tetrahydroisoquinoline (1MeTIQ) is an endogenous antidepressant and parkinsonism-preventing substance that demonstrates neuroprotectiveactivity. Following systemic administration in rats, 1-Methyl-1,2,3,4-tetrahydroisoquinoline produces antidepressant-like effect similar to the effect of imipramine. 1MeTIQ is a reversible short-acting moderate inhibitor of MAO A/B.

The aim of this paper was to investigate whether rotenone, a pesticide causing experimental parkinsonism, causes direct damage to dopaminergic structure when injected intracerebrally and whether this action may be prevented by peripheral administration of 1-methyl-1,2,3,4-tetrahydroisoquinoline (1MeTIQ), an endogenous compound
