Abstract
Intramolecular hydroarylation-redox cross-dehydrogenative coupling of N-propargylanilines with phosphite diesters proceeded in the presence of Cu(I)-catalysts (20 mol%) to selectively give 2-phosphono-1,2,3,4-tetrahydroquinolines in good yields with 100% atomic utilization. P-H and two C-H bonds are activated at once and these hydrogen atoms are trapped by a propargylic triple bond in the molecule.

Abstract
Due to their structural similarity with natural α-amino acids, α-aminophosphonic acid derivatives are known biologically active molecules. In view of the relevance of tetrasubstituted carbons in nature and medicine and the strong dependence of the biological activity of chiral molecules into their absolute configuration, the synthesis of α-aminophosphonates bearing tetrasubstituted carbons in an asymmetric fashion has grown in interest in the past few decades. In the following lines, the existing literatures for the synthesis of optically active tetrasubstituted α-aminophosphonates are summarized, comprising diastereoselective and enantioselective approaches.

Abstract
Proteases catalyze the hydrolysis of peptide bonds. Products of this breakdown mediate signaling in an enormous number of biological processes. Serine proteases constitute the most numerous group of proteases, accounting for 40%, and they are prevalent in many physiological functions, both normal and disease-related functions, making them one of the most important enzymes in humans. The activity of proteases is controlled at the expression level by posttranslational modifications and/or endogenous inhibitors. The study of serine proteases requires specific reagents not only for detecting their activity but also for their imaging. Such tools include inhibitors or substrate-related chemical molecules that allow the detection of proteolysis and visual observation of active enzymes, thus facilitating the characterization of the activity of proteases in the complex proteome. Peptidyl activity-based probes (ABPs) have been extensively studied recently, and this review describes the basic principles in the design of peptide-based imaging agents for serine proteases, provides examples of activity-based probe applications and critically discusses their strengths, weaknesses, challenges and limitations.

Abstract
Serine proteases comprise about one-third of all proteases, and defective regulation of serine proteases is involved in numerous diseases. Therefore, serine protease inhibitors are promising drug candidates. Aminomethyl diphenyl phosphonates have been regularly used as scaffolds for covalent serine protease inhibition and the design of activity-based probes. However, they cannot make use of a protease's primed site. Therefore, we developed a facile two-step synthesis toward a set of phenyl phosphinates, which is a related scaffold but can interact with the primed site. We tested their inhibitory activity on five different serine proteases and found that a phenyl group directly attached to the phosphorus atom leads to superior activity compared with phosphonates.

Abstract
Human neutrophil elastase (HNE) is a potent serine protease belonging to the chymotrypsin family and is involved in a variety of pathologies affecting the respiratory system. Thus, compounds able to inhibit HNE proteolytic activity could represent effective therapeutics. We present here the synthesis of new thiazol-2-(3H)-ones as an elaboration of potent HNE inhibitors with an isoxazol-5-(2H)-one scaffold that we recently identified. Two-dimensional NMR spectroscopic techniques and tandem mass spectrometry allowed us to correctly assign the structure of the final compounds arising from both tautomers of the thiazol-2-(3H)-one nucleus (N-3 of the thiazol-2-(3H)-one and 3-OH of the thiazole). All new compounds were tested as HNE inhibitors, and no activity was found at the highest concentration used (40 µM), demonstrating that the thiazol-2-(3H)-one is not a good scaffold for HNE inhibitors. Molecular modelling experiments indicate that the low-energy pose might limit the nucleophilic attack on the endocyclic carbonyl group of the thiazolone-based compounds by HNE catalytic Ser195, in contrast to isoxazol-5-(2H)-one analogues.![]()

Abstract
Proteases are enzymes that hydrolyze the peptide bond of peptide substrates and proteins. Despite significant progress in recent years, one of the greatest challenges in the design and testing of substrates, inhibitors and activity‐based probes for proteolytic enzymes is achieving specificity toward only one enzyme. This specificity is particularly important if the enzyme is present with other enzymes with a similar catalytic mechanism and substrate specificity but completely different functionality. The cross‐reactivity of substrates, inhibitors and activity‐based probes with other enzymes can significantly impair or even prevent investigations of a target protease. In this review, we describe important concepts and the latest challenges, focusing mainly on peptide‐based substrate specificity techniques used to distinguish individual enzymes within major protease families.

Bifunctional Cinchona alkaloid thioureas efficiently catalyze asymmetric nucleophilic addition of nitromethane to ketimines derived from α-aminophosphonic acids to afford tetrasubstituted α-amino-β-nitro-phosphonates. Catalytic hydrogenation of (S)-α-amino-β-nitro-phosphonate 2d gives enantiopure (S)-α,β-diaminophosphonate 3.

Abstract
Neutrophils are a type of granulocyte important in the "first line of defense" of the innate immune system. Upon activation, they facilitate the destruction of invading microorganisms by the production of superoxide radicals, as well as the release of the enzymatic contents of their lysozymes. These enzymes include specific serine proteases: cathepsin G, neutrophil elastase, proteinase 3, as well as the recently discovered neutrophil serine protease 4 (NSP4). Under normal conditions, the proteolytic activity of neutrophil proteases is tightly regulated by endogenous serpins; however, this mechanism can be subverted during tissue stress, thereby resulting in the uncontrolled activity of serine proteases, which induce chronic inflammation and subsequent pathology. Herein, we describe the development of low-molecular-weight activity-based probes that specifically target the active sites of neutrophil proteases.

Abstract
Staphylococcus aureus is responsible for a variety of human infections, including life-threatening, systemic conditions. Secreted proteome, including a range of proteases, constitutes the major virulence factor of the bacterium. However, the functions of individual enzymes, in particular SplA protease, remain poorly characterized. Here, we report development of specific inhibitors of SplA protease. The design, synthesis, and activity of a series of α-aminoalkylphosphonate diaryl esters and their peptidyl derivatives are described. Potent inhibitors of SplA are reported, which may facilitate future investigation of physiological function of the protease. The binding modes of the high-affinity compounds Cbz-Phe(P) -(OC6 H4 -4-SO2 CH3 )2 and Suc-Val-Pro-Phe(P) -(OC6 H5 )2 are revealed by high-resolution crystal structures of complexes with the protease. Surprisingly, the binding mode of both compounds deviates from previously characterized canonical interaction of α-aminoalkylphosphonate peptidyl derivatives and family S1 serine proteases.
