Simultaneous engineering of an enzyme’s entrance tunnel and active site: The case of monoamine oxidase MAO-N

A new directed evolution approach is presented to enhance the activity of an enzyme and to manipulate stereoselectivity by focusing iterative saturation mutagenesis (ISM) simultaneously on residues lining the entrance tunnel and the binding pocket. This combined mutagenesis strategy was applied successfully to the monoamine oxidase from Aspergillus Niger (MAO-N) in the reaction of sterically demanding substrates which are of interest in the synthesis of chiral pharmaceuticals based on the benzo-piperidine scaffold. Reversal of enantioselectivity of Turner-type deracemization was achieved in the synthesis of (S)-1,2,3,4-tetrahydro-1-methyl-isoquinoline, (S)-1,2,3,4-tetrahydro-1-ethylisoquinoline and (S)-1,2,3,4-tetrahydro-1-isopropylisoquinoline. Extensive molecular dynamics simulations indicate that the altered catalytic profile is due to increased hydrophobicity of the entrance tunnel acting in concert with the altered shape of the binding pocket.

Highly efficient and recyclable magnetic nanoparticles-supported gold(III)-bipy catalyst for oxidative alpha-cyanation of tertiary amines

Oxidative alpha-cyanation of tertiary amines with trimethylsilyl cyanide was achieved by using a magnetic nanoparticles-supported gold(III)-bipy complex as catalyst to afford the corresponding alpha-aminonitriles in good to excellent yields in the presence of tert-butyl hydroperoxide under acid-free conditions. The new heterogeneous gold catalyst can easily be separated from the reaction mixture by using an external magnet and can be recycled for at least 10 times without any loss of activity.

Free radical-mediated aryl amination and its use in a convergent [3 + 2] strategy for enantioselective indoline alpha-amino acid synthesis

The scope of aryl radical additions to the nitrogen of azomethines is described. Aryl, trifluoromethyl alkyl, and alpha,beta-unsaturated ketimines engage in regioselective aryl-nitrogen bond formation via 5-exo cyclizations of an aryl radical to azomethine nitrogen. Selectivity for carbon-nitrogen over carbon-carbon bond formation is generally high (>95:5) and competes only with direct aryl radical reduction by stannane (0-10%). alpha-Ketoimines are a promising new class of carbon radical acceptors for which no competitive aryl radical reduction is observed. The reaction conditions are pH-neutral and are therefore among the mildest methods available for amination of an aromatic ring. The ketimines examined did not suffer from competitive reduction by stannane, offering an advantage over the use of diazo and azide functional groups as nitrogen sources for carbon radicals. The free radical-mediated aryl amination was sequenced with the O’Donnell phase transfer-catalyzed enantioselective alkylation strategy of glycinyl imine to provide either enantiomer of indoline alpha-amino acids with high ee. These new constrained phenyl alanine derivatives are now readily available for evaluation across a variety of applications.

Chiral, thermal-responsive hydrogels containing helical hydrophilic polyacetylene: Preparation and enantio-differentiating release ability

In this contribution, a chiral N-propargylamide monomer (R and S) was synthesized and used as a comonomer to prepare hydrophilic polyacetylene (HPA) bearing polymerizable vinyl groups in the presence of (nbd)Rh+B-(C6H5)4. The obtained HPA chains could form a single-handed helical structure in water and showed intense optical activity. Taking advantage of the hydrophilic and polymerizable moieties, HPA was further used as a macromer to prepare hydrogels in deionized water via free radical polymerization, using N-isopropylacrylamide (NIPAm) as a co-monomer, N,N-methylenebisacrylamide (BIS) as a crosslinker, and ammonium persulphate (APS) and N,N,N,N-tetramethylethylenediamine (TEMEDA) as redox initiators. The as-prepared hydrogels exhibited optical activity, thermal responsivity and biocompatibility. More interestingly, the hydrogels showed enantio-differentiating release ability towards mandelic acid enantiomers, demonstrating the potential applications of these novel optically active hydrogels in chiral drug delivery fields.

Pyridinylimidazoles as dual glycogen synthase kinase 3beta/p38alpha mitogen-activated protein kinase inhibitors

Compounds simultaneously inhibiting two targets that are involved in the progression of the same complex disease may exhibit additive or even synergistic therapeutic effects. Here we unveil 2,4,5-trisubstituted imidazoles as dual inhibitors of p38alpha mitogen-activated protein kinase and glycogen synthase kinase 3beta (GSK3beta). Both enzymes are potential therapeutic targets for neurodegenerative disorders, like Alzheimer’s disease. A set of 39 compounds was synthesized and evaluated in kinase activity assays for their ability to inhibit both target kinases. Among the synthesized compounds, potent dual-target-directed inhibitors showing IC50 values down to the low double-digit nanomolar range, were identified. One of the best balanced dual inhibitors presented in here is N-(4-(2-ethyl-4-(4-fluorophenyl)-1H-imidazol-5-yl)pyridin-2-yl)cyclopropanecarboxamide (20c) (p38alpha, IC50 = 16 nM; GSK3beta, IC50 = 35 nM) featuring an excellent metabolic stability and an appreciable isoform selectivity over the closely related GSK3alpha. Our findings were rationalized by computational docking studies based on previously published X-ray structures.

Catalytic asymmetric ¡À-acylation of tertiary amines mediated by a dual catalysis mode: N-heterocyclic carbene and photoredox catalysis

Cross-coupling reactions are among the most widely utilized methods for C-C bond formation; however, the requirement of preactivated starting materials still presents a major limitation. Methods that take direct advantage of the inherent reactivity of the C-H bond offer an efficient alternative to these methods, negating the requirement for substrate preactivation. In this process, two chemically distinct activation events culminate in the formation of the desired C-C bond with loss of H2 as the only byproduct. Herein we report the catalytic asymmetric ¡À-acylation of tertiary amines with aldehydes facilitated by the combination of chiral N-heterocyclic carbene catalysis and photoredox catalysis.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! Read on for other articles about 141-30-0!, 3340-78-1
