Alkaloids are traditionally defined as basic (alkali‐like), nitrogen‐containing organic constituents that occur mainly in plants. The nitrogen in the alkaloid molecule is derived from amino acid metabolism. Since the amino acid skeleton is often largely retained in the alkaloid structure, alkaloids originating from the same amino acid show similar structural features and can be classified according to their biosynthetic origin. The biosynthesis of alkaloids often follows complex pathways and includes stereospecific steps. Alkaloids often have pronounced bioactivities and are therefore thought to play an important role in the interaction of plants with their environment. Alkaloids and extracts of alkaloid‐containing plants have been used throughout human history as remedies, poisons and psychoactive drugs.

Alkaloids are defined as basic compounds derived from amino acids, often with heterocyclically bound nitrogen. Pseudoalkaloids are nitrogen‐containing natural products that do not arise from an amino acid core and acquire their nitrogen by transamination of a precursor derived from other biosynthetic pathways.

AB - The prodiginine family of bacterial alkaloids is a diverse set of heterocyclic natural products that have likely been known to man since antiquity. In more recent times, these alkaloids have been discovered to span a wide range of chemical structures that possess a number of interesting biological activities. This review provides a comprehensive overview of research undertaken toward the isolation and structural elucidation of the prodiginine family of natural products. Additionally, research toward chemical synthesis of the prodiginine alkaloids over the last several decades is extensively reviewed. Finally, the current, evidence-based understanding of the various biosynthetic pathways employed by bacteria to produce prodiginine alkaloids is summarized.
