Structural biology of proline catabolic enzymes

Significance: Proline catabolism refers to the 4-electron oxidation of proline to glutamate catalyzed by the enzymes proline dehydrogenase (PRODH) and l-glutamate gamma-semialdehyde dehydrogenase (GSALDH, or ALDH4A1). These enzymes and the intermediate metabolites of the pathway have been implicated in tumor growth and suppression, metastasis, hyperprolinemia metabolic disorders, schizophrenia susceptibility, life span extension, and pathogen virulence and survival. In some bacteria, PRODH and GSALDH are combined into a bifunctional enzyme known as proline utilization A (PutA). PutAs are not only virulence factors in some pathogenic bacteria but also fascinating systems for studying the coordination of metabolic enzymes via substrate channeling. Recent Advances: The past decade has seen an explosion of structural data for proline catabolic enzymes. This review surveys these structures, emphasizing protein folds, substrate recognition, oligomerization, kinetic mechanisms, and substrate channeling in PutA. Critical Issues: Major unsolved structural targets include eukaryotic PRODH, the complex between monofunctional PRODH and monofunctional GSALDH, and the largest of all PutAs, trifunctional PutA. The structural basis of PutA-membrane association is poorly understood. Fundamental aspects of substrate channeling in PutA remain unknown, such as the identity of the channeled intermediate, how the tunnel system is activated, and the roles of ancillary tunnels. Future Directions: New approaches are needed to study the molecular and in vivo mechanisms of substrate channeling. With the discovery of the proline cycle driving tumor growth and metastasis, the development of inhibitors of proline metabolic enzymes has emerged as an exciting new direction. Structural biology will be important in these endeavors.

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.

Synthesis of Functionalized Cyclopropanes from Carboxylic Acids by a Radical Addition?Polar Cyclization Cascade

Herein, we describe the development of a photoredox-catalyzed decarboxylative radical addition?polar cyclization cascade approach to functionalized cyclopropanes. Reductive termination of radical?polar crossover reactions between aliphatic carboxylic acids and electron-deficient alkenes yielded carbanion intermediates that were intercepted in intramolecular alkylations with alkyl chlorides appended to the alkene substrate. The mild conditions, which make use of a readily available organic photocatalyst and visible light, were demonstrated to be amenable to a broad range of structurally complex carboxylic acids and a wide variety of chloroalkyl alkenes, demonstrating exquisite functional group tolerance.

Photo-induced Decarboxylative Heck-Type Coupling of Unactivated Aliphatic Acids and Terminal Alkenes in the Absence of Sacrificial Hydrogen Acceptors

1,2-Disubstituted alkenes such as vinyl arenes, vinyl silanes, and vinyl boronates are among the most versatile building blocks that can be found in every sector of chemical science. We herein report a noble-metal-free method of accessing such olefins through a photo-induced decarboxylative Heck-type coupling using alkyl carboxylic acids, one of the most ubiquitous building blocks, as the feedstocks. This transformation was achieved in the absence of external oxidants through the synergistic combination of an organo photo-redox catalyst and a cobaloxime catalyst, with H2 and CO2 as the only byproducts. Both control experiments and DFT calculations supported a radical-based mechanism, which eventually led to the development of a selective three-component coupling of aliphatic carboxylic acids, acrylates, and vinyl arenes. More than 90 olefins across a wide range of functionalities were effectively synthesized with this simple protocol.

Remote Effects Modulating the Spin Equilibrium of the Resting State of Cytochrome P450cam – An Investigation Using Active Site Analogues

The crystal structure of the resting state of cytochrome P450 cam (CYP101), a heme thiolate protein, shows a cluster of six water molecules in the substrate binding pocket, one of which is coordinating to iron(III) as sixth ligand. The resting state is low-spin and changes to high-spin when substrate camphor binds and H2O is removed. In contrast to the protein, previously synthesised enzyme models such as H 2O-FeIII(porph)(ArS-) were shown to be purely high-spin. Iron(S-)porphyrins with different distal sites mimicking proposed remote effects have been prepared and studied by cw-EPR. The results indicate that the low-spin of the resting state of P450cam is due to the fact that the water molecule coordinating to iron has an OH –like character because of hydrogen bonding and polarisation of the water cluster, respectively.
