Biosynthesis of Isoquinoline Alkaloids [PDF]
Planta Medica, 1979 The isoquinoline alkaloids and their biosynthetic relatives include many compounds which show important physiological properties in animals: dopamine, mescaline, morphine, papaverine, and narcotine are pertinent examples. The biosynthetic routes to the members of this family start from the essential aminoacids tyrosine or phenylalanine. Decarboxylation
