Description

1-Benzylisoquinoline is the structural backbone of many alkaloids with a wide variety of structures, including papaverine, noscapine, codeine, morphine, apomorphine, berberine, protopine and tubocurarine.

Biosynthesis

Plants producing benzylisoquinoline alkaloids have a common biosynthetic pathway, making use of two units of L-tyrosine. One tyrosine molecule is metabolised to dopamine which constitutes the isoquinoline part, while the benzylic part is mostly formed from tyramine, itself the decarboxylation product of tyrosine.

Many benzylisoquinolines have a methylated nitrogen atom as well as functional groups containing oxygen (-OH, -OCH₃, -OCH₂O-) in positions 6, 7, 3' and 4'. The latter come from the precursors mentioned above, namely tyrosine, dopamine and their derivatives.
