Metabolite Identification
Common NameTerrequinone A
DescriptionTerrequinone A is a bis-indolylquinone natural product known for its antitumor activity. It has been identified as a metabolite with moderate inhibitory effects on acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE), with IC50 values of 11.10 ± 0.38 µg/mL and 5.06 ± 0.15 µg/mL for AChE, and 15.63 ± 1.27 µg/mL and 8.02 ± 0.08 µg/mL for BuChE, respectively (PMID:36985531 ). The biosynthesis of terrequinone A has been successfully engineered in Escherichia coli, utilizing L-tryptophan and prenol as starting materials. A synthetic pathway incorporating the tdiA-tdiE genes was constructed and activated by the phosphopantetheinyl transferase gene sfp, resulting in the production of 1.54 mg/L of terrequinone A, which was further optimized to yield up to 106.3 mg/L under specific culture conditions (PMID:36859334 ). This metabolic engineering approach not only enhances the synthesis of terrequinone A but also provides a framework for producing other bis-indolylquinones with asymmetric quinone cores, highlighting its potential for biotechnological applications in drug development (PMID:36859334 ).
