Alkaloid
Alkaloid — A class of naturally occurring nitrogen-containing organic compounds, some of which interact with the same biological targets as bioactive peptides.
What Is an Alkaloid?
An alkaloid is a nitrogen-containing natural product typically derived from plants. While alkaloids are not peptides, several important alkaloid-peptide hybrids exist in nature, and alkaloid chemistry intersects with peptide research through coupling reagent chemistry, protecting group strategies, and natural product-inspired peptidomimetic design.
Peptide Connections
- Ergot peptides: Ergotamine contains a tripeptide linked to lysergic acid (alkaloid-peptide hybrid)
- Cyclopeptide alkaloids: Macrocyclic compounds bridging peptide and alkaloid chemistry
- Non-ribosomal peptides: Some contain alkaloid-derived building blocks
