There is no uniform classification. This classification is now considered obsolete. This group also includes some alkaloids that besides the nitrogen heterocycle contain terpene e.
The piperidine alkaloids coniine and coniceine may be regarded as true alkaloids rather than pseudoalkaloids: see below  although they do not originate from amino acids. Second, the introduction of a new branch into the pathway has been shown to produce novel metabolites.
Finally, the possibility of accumulating a pathway intermediate by the knock-down of a key step is examined. Further metabolic modification is also discussed, since the latter two modifications may lead to the production of novel compound s from an accumulated intermediate through metabolic activation.

Clin Exp Immun All the enzymes identified that appear to participate in gaudichaudianic acid biosynthesis in Piper gaudichaudianum are presented in Table 3 , and a proposed scheme for this pathway is shown in Figure 5.
Conclusions This study presents for the first time the transcriptome analysis of Piper gaudichaudianum using a next-generation sequencing approach. This approach allowed for the identification of the main active biosynthetic pathways in this species, such as those involved in the formation of terpenoids, phenylpropanoids, flavonoids, and isoquinoline alkaloids. These data corroborate and complement previous studies performed on Piper gaudichaudianum.
However, the main contribution of this work concerns the biosynthesis of p-hydroxybenzoic acid-derived benzopyrans. Despite the advent of sequencing technologies that facilitate the elucidation of plant secondary metabolism, many genes in the benzoic acid derivative biosynthetic network remain to be discovered.
Moreover, the transcriptome analysis revealed the presence of prenyltransferases and tocopherol cyclase enzyme genes, which may be responsible for the prenylation and cyclization that yield the 2H-pyran moiety.I, — a.
