7,8-Dichloro-1,2,3,4-tetrahydroisoquinoline (compound 11), a tetrahydroisoquinoline (THIQ) derivative, is a selective phenylethanolamine N-methyltransferase (PNMT) inhibitor with a Ki value of 0.3 μM. 7,8-Dichloro-1,2,3,4-tetrahydroisoquinoline can be used in research on psychiatric disorders related to Alzheimer's disease and Parkinson's disease[1].

ChEBI: A 1,2,3,4-tetrahydroisoquinoline hacing chloro substituents at the 7- and 8-positions.
