Biotransformation Of l‐Tryptophan To Produce Arcyriaflavin A With Pseudomonas putida KT2440
ChemBioChem, Volume 24, Issue 23, December 1, 2023., 2023 Arcyriaflavin A was produced in Pseudomonas putida KT2440 using genes from Lentzea aerocolonigenes. Cultivation conditions and supply of the precursor l‐tryptophan were optimized. Genetic engineering of outer membrane vesicle release and cultivation with polyurethane adsorbent resulted in product enrichment in the supernatant.

Antemitotic activity of strychnopentamine, a bisindolic alkaloid
Journal of Ethnopharmacology, 1984 Strychnopentamine has been tested for its cytotoxic and antitumor activities and compared with two other bisindolic alkaloids that possess an usambarane skeleton. The presence of a N-methylpyrrolidine group increases the antimitotic activity of this type of alkaloids.
