Chapter Iv: Production of (r, S)-reticuline and Downstream Benzylisoquinoline Alkaloids in Saccharomyces Cerevisiae
The benzylisoquinoline alkaloids (BIAs) are a diverse class of plant secondary metabolites that exhibit a broad range of pharmacological activities and are synthesized through biosynthetic pathways that exhibit complex enzyme activities and regulatory strategies. We have engineered yeast to produce the major branch point intermediate reticuline and downstream BIA metabolites from a commercially...
متن کاملSynthesis of Morphinan Alkaloids in Saccharomyces cerevisiae
Morphinan alkaloids are the most powerful narcotic analgesics currently used to treat moderate to severe and chronic pain. The feasibility of morphinan synthesis in recombinant Saccharomyces cerevisiae starting from the precursor (R,S)-norlaudanosoline was investigated. Chiral analysis of the reticuline produced by the expression of opium poppy methyltransferases showed strict enantioselectivit...
متن کاملGreen Routes for the Production of Enantiopure Benzylisoquinoline Alkaloids
Benzylisoquinoline alkaloids (BIAs) are among the most important plant secondary metabolites, in that they include a number of biologically active substances widely employed as pharmaceuticals. Isolation of BIAs from their natural sources is an expensive and time-consuming procedure as they accumulate in very low levels in plant. Moreover, total synthesis is challenging due to the presence of s...
متن کاملStructure-antioxidative activity relationships in benzylisoquinoline alkaloids.
The antioxidative properties of the aporphines boldine, glaucine and apomorphine, and of the benzyltetrahydroisoquinolines (+/-)-coclaurine and (+/-)-norarmepavine were compared in the brain homogenate autoxidation model. The IC50 values found lay in the 16-20 microM range for the aporphines and were 131.7 microM, and 79.3 microM for coclaurine and norarmepavine, respectively. These results ind...
متن کاملBIAdb: A curated database of benzylisoquinoline alkaloids
BACKGROUND Benzylisoquinoline is the structural backbone of many alkaloids with a wide variety of structures including papaverine, noscapine, codeine, morphine, apomorphine, berberine, protopine and tubocurarine. Many benzylisoquinoline alkaloids have been reported to show therapeutic properties and to act as novel medicines. Thus it is important to collect and compile benzylisoquinoline alkalo...
