Carnegine, also known as pectenine, DMMM-4, or 6,7-dimethoxy-1,2-dimethyl-1,2,3,4-tetrahydroisoquinoline, is a tetrahydroisoquinoline and cyclized phenethylamine alkaloid found in Carnegiea gigantea, Pachycereus pringlei, and other cacti.^[1]^[2]^[3]^[4]^[5]^[6]^[7]

It is known to be pharmacologically active, including acting as a relatively potent monoamine oxidase inhibitor (MAOI), specifically of monoamine oxidase A (MAO-A) (K_i = 2 μM for the (R)-enantiomer) but not of monoamine oxidase B (MAO-B), producing strychnine-like convulsions in animals, and having other actions and effects.^[2]^[3]^[8] Carnegine and similar alkaloids might potentiate the effects of mescaline and related compounds like N-methylmescaline via their MAOI activity.^[3]^[2]^[9]

The compound was first isolated in 1901 and its structure and synthesis were established in 1929.^[4]^[3]
