Tetrahydropapaveroline, also known as norlaudanosoline, is a tetrahydroisoquinoline alkaloid. It is also classified as a benzylisoquinoline alkaloids.^[1]

Brain biochemistry

Tetrahydropapaveroline is relevant to brain pathologies.^[2]

It can be formed in trace amounts in the brain by a condensation reaction of dopamine and dopaldehyde (a metabolite of dopamine).^[2]^[3]

It inhibits dopamine uptake within the cerebral cortex.^[4]
