Article
New drugs introduced to the market are privileged structures that have affinities for biological targets implicated in human diseases and conditions. These new chemical entities (NCEs), particularly small molecules and antibody-drug conjugates (ADCs), provide insight into molecular recognition and simultaneously function as leads for the design of...
Article
Biocatalysis has become an important aspect of modern organic synthesis, both in academia and across the chemical and pharmaceutical industries. Its success has been largely due to a rapid expansion of the range of chemical reactions accessible, made possible by advanced tools for enzyme discovery coupled with high-throughput laboratory evolution t...

Article
Sickle cell disease (SCD) is a genetic disorder caused by a single point mutation (β6 Glu → Val) on the β-chain of adult hemoglobin (HbA) that results in sickled hemoglobin (HbS). In the deoxygenated state, polymerization of HbS leads to sickling of red blood cells (RBC). Several downstream consequences of polymerization and RBC sickling include va...
Article
Enantiopure α-aryl propionic acids are useful building blocks for pharmaceutical research and can be accessed enzymatically using arylmalonate decarboxylases (AMDases) from the corresponding malonic acids. However, the intrinsic instability of malonic acids is a major drawback to this approach in which spontaneous decarboxylation can occur, subsequ...
Article
Ene-reductases (EREDs) catalyse the reduction of electron-deficient C=C bonds. Herein, we report the first example of ERED-catalysed net reduction of C=C bonds of enimines (α,β-unsaturated imines). Preliminary studies suggest their hydrolysed ring-open ω-amino enones are the likely substrates for this step. When combined with imine reductase (IRED)...
Article
Carboxylic acid reductases (CARs) are an emerging biocatalyst platform for the synthesis of a diverse array of aldehydes from carboxylic acids, operating chemoselectively and under mild aqueous conditions. As such, there is growing interest in the industrial application of these enzymes, both for the synthesis of aldehyde end-products, which are pa...
Article
Reductive Aminases (RedAms) catalyze the asymmetric reductive amination of ketones with primary amines to give secondary amine products. RedAms have great potential for the synthesis of bioactive chiral amines, however, insights into their mechanism are currently limited. Comparative studies on reductive amination of cyclohexanone with allylamine i...
Chapter
Synthesis of the chiral amine moiety is a key challenge for synthetic organic chemistry due to its prevalence in many biologically active molecules. Imine reductase and amine oxidase enzymes have enabled the biocatalytic synthesis of a host of chiral amine compounds. In this chapter, procedures for the synthesis of chiral amines using imine reducta...
Article
Biocatalytic retrosynthetic analysis of dibenz[c,e]azepines has highlighted the use of imine reductase (IRED) and w-transaminase (w-TA) biocatalysts to establish the key stereocentres of these molecules. Several enantiocomplementary IREDs were identified for the synthesis of (R)- and (S)-5-methyl-6,7-dihydro-5H-dibenz[c,e]azepine with excellent ena...

Article
The NADP(H)-dependent reductive aminase from Aspergillus oryzae (AspRedAm) has been combined with an NADPH oxidase (NOX) to develop a redox system that recycles the co-factor. The AspRedAm-NOX system has been applied initially for the kinetic resolution of a variety of racemic secondary and primary amines to yield (S)-configured amines with enantio...
Article
Reductive amination of carbonyl compounds constitutes one of the most efficient ways to rapidly construct chiral and achiral amine frameworks. Imine reductase (IRED) biocatalysts represent a versatile family of enzymes for amine synthesis via NADPH mediated imine reduction. The reductive aminases (RedAms) are a sub-family of IREDs which have recent...
Article
Reductive amination is one of the most important methods for the synthesis of chiral amines. Here we report the discovery of an NADP(H)-dependent reductive aminase from Aspergillus oryzae (AspRedAm, Uniprot code Q2TW47) which can catalyse the reductive coupling of a broad set of carbonyl compounds with a variety of primary and secondary amines with...
Article
Imine reductases (IREDs) have emerged as a valuable new set of biocatalysts for the asymmetric synthesis of optically active amines. The development of bioinformatics tools and searchable databases has led to the identification of a diverse range of new IRED biocatalysts that have been characterised and employed in different synthetic processes. Th...
Article
The increasing diversity of reactions mediated by biocatalysts has led to development of multi-step in vitro enzyme cascades, taking advantage of generally compatible reaction conditions. The construction of pathways within single whole cell systems is much less explored, yet has many advantages. Herein we report the generation of a successful whol...
Article
The combination of sequential biocatalytic reactions, via non-natural synthetic cascades, is a rapidly developing field and leads to the generation of complex valuable chemicals from simple precursors. As the toolbox of available biocatalysts continues to expand, so do the options for biocatalytic retrosynthesis of a target molecule, leading to alt...
Article
The imine reductase AoIRED from Amycolatopsis orientalis (Uniprot R4SNK4) catalyzes the NADPH-dependent reduction of a wide range of prochiral imines and iminium ions, predominantly with (S)-selectivity and with e.e.s of up to >99%. AoIRED displays up to 100-fold greater catalytic efficiency for 2-methyl-1-pyrroline (2MPN) compared to other IREDs,...
Article
Access to enantiomerically pure chiral mono- and disubstituted piperidines and pyrrolidines has been achieved using a biocatalytic cascade involving carboxylic acid reductase (CAR), ω-transaminase (ω-TA), and imine reductase (IRED) enzymes. Starting from keto acids or keto aldehydes, substituted piperidine or pyrrolidine frameworks can be generated...
Article
Although the range of biocatalysts available for the synthesis of enantiomerically pure chiral amines continues to expand, few existing methods provide access to secondary amines. To address this shortcoming, we have over-expressed the gene for an (R)-imine reductase [(R)-IRED] from Streptomyces sp. GF3587 in Escherichia coli to create a recombinan...
Article
The ability of urea-linked oligomers of achiral diamines (achiral analogues of the well-established chiral oligourea foldamers) to adopt helical conformations was explored spectroscopically. Up to four achiral units were ligated either to a well-formed helical trimer or to a single chiral diamine, and the extent to which they adopted a screw-sense...
