Facile Synthesis of Aminomethyl Phosphinate Esters as Serine Protease Inhibitors with Primed Site Interaction.

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.

Phosphinate esters as novel warheads for activity-based probes targeting serine proteases.

Project description:Activity-based protein profiling enables the specific detection of the active fraction of an enzyme and is of particular use for the profiling of proteases. The technique relies on a mechanism-based reaction between small molecule activity-based probes (ABPs) with the active enzyme. Here we report a set of new ABPs for serine proteases, specifically neutrophil serine proteases. The probes contain a phenylphosphinate warhead that mimics the P1 amino acid recognized by the primary recognition pocket of S1 family serine proteases. The warhead is easily synthesized from commercial starting materials and leads to potent probes which can be used for fluorescent in-gel protease detection and fluorescent microscopy imaging experiments.

Macrocyclic Inhibitors Targeting the Prime Site of the Fibrinolytic Serine Protease Plasmin.

Project description:Two series of macrocyclic inhibitors addressing the S1 pocket and the prime site of the fibrinolytic serine protease plasmin have been developed. In the first series, a P1 tranexamoyl residue was coupled to 4-aminophenylalanine in P1' position, which provided moderately potent inhibitors with inhibition constants around 1 μM. In the second series, a substituted biphenylalanine was incorporated as P1' residue leading to approximately 1000-fold stronger plasmin inhibitors, the best compounds possess subnanomolar inhibition constants. The most effective compounds already exhibit a certain selectivity as plasmin inhibitors compared to other trypsin-like serine proteases such as trypsin, plasma kallikrein, thrombin, activated protein Ca, as well as factors XIa and Xa. For inhibitor 28 of the second series, the co-crystal structure in complex with a Ser195Ala microplasmin mutant revealed that the P2' residue adopts multiple conformations. Most polar contacts to plasmin and surrounding water molecules are mediated through the P1 tranexamoyl residue, whereas the bound conformation of the macrocycle is mainly stabilized by two intramolecular hydrogen bonds.

Alkylation of H-phosphinate esters under basic conditions.

Project description:An efficient and general procedure was developed for the direct alkylation of H-phosphinate esters with LHMDS at low temperature. The simplicity of the reaction allows the use of various H-phosphinate esters and takes place with a wide range of electrophiles. The approach can be employed to access some GABA analogues or precursors to GABA analogues. The isolated yields are moderate to good. This is the first report of an alkylation with a secondary iodide or a primary chloride.

Virtual Screening of Transmembrane Serine Protease Inhibitors.

Project description:The human family of type II transmembrane serine proteases includes 17 members. The defining features of these proteases are an N-terminal transmembrane domain and a C-terminal serine protease of the chymotrypsin (S1) fold, separated from each other by a variable stem region. Recently accumulated evidence suggests a critical role for these proteases in development of cancer and metastatic capacity. Both the cancer relevance and the accessibility of the extracellularly oriented catalytic domain for therapeutic and imaging agents have fueled drug discovery interest in the type II class of transmembrane serine proteases. Typically, the initial hit discovery processes aim to identify molecules with verifiable activity at the drug target and with sufficient drug-like characters. We present here protocols for structure-based virtual screening of candidate ligands for transmembrane serine protease hepsin. The methods describe use of the 3D structure of the catalytic site of hepsin for molecular docking with ZINC, which is a molecular database of > 30 million purchasable compounds. Small candidate subsets were experimentally tested with demonstrable hits, which provided meaningful cues of the ligand structures for further lead development.

Schistosome serine protease inhibitors: parasite defense or homeostasis?

Project description:Serpins are a structurally conserved family of macromolecular inhibitors found in numerous biological systems. The completion and annotation of the genomes of Schistosoma mansoni and Schistosoma japonicum has enabled the identification by phylogenetic analysis of two major serpin clades. S. mansoni shows a greater multiplicity of serpin genes, perhaps reflecting adaptation to infection of a human host. Putative targets of schistosome serpins can be predicted from the sequence of the reactive center loop (RCL). Schistosome serpins may play important roles in both post-translational regulation of schistosome-derived proteases, as well as parasite defense mechanisms against the action of host proteases.

Palladium-Catalyzed Allylation/Benzylation of H-Phosphinate Esters with Alcohols.

Project description:The Pd-catalyzed direct alkylation of H-phosphinic acids and hypophosphorous acid with allylic/benzylic alcohols has been described previously. Here, the extension of this methodology to H-phosphinate esters is presented. The new reaction appears general, although its scope is narrower than with the acids, and its mechanism is likely different. Various alcohols are examined in their reaction with phosphinylidene compounds R¹R²P(O)H.

Alanine serine cysteine transporter (ASCT) substrate binding site properties probed with hydroxyhomoserine esters.

Project description:The glutamine transporter ASCT2 is highly overexpressed in cancer cells. Block of glutamine uptake by ASCT2 is a potential strategy to inhibit growth of cancer cells. However, pharmacology of the ASCT2 binding site is not well established. In this work, we report the computational docking to the binding site, and the synthesis of a new class of ASCT2 inhibitors based on the novel L-hydroxyhomoserine scaffold. While these compounds inhibit the ASCT2 leak anion conductance, as expected for competitive inhibitors, they did not block leak conductance in glutamate transporters (EAAT1-3 and EAAT5). They were also ineffective with respect to subtype ASCT1, which has >57% amino acid sequence similarity to ASCT2. Molecular docking studies agree very well with the experimental results and suggest specific polar interactions in the ASCT2 binding site. Our findings add to the repertoire of ASCT2 inhibitors and will aid in further studies of ASCT2 pharmacology.

Structure-activity relationships of heteroaromatic esters as human rhinovirus 3C protease inhibitors.

Project description:Human rhinovirus 3C protease (HRV 3C(pro)) is known to be a promising target for development of therapeutic agents against the common cold because of the importance of the protease in viral replication as well as its expression in a large number of serotypes. To explore non-peptidic inhibitors of HRV 3C(pro), a series of novel heteroaromatic esters was synthesized and evaluated for inhibitory activity against HRV 3C(pro), to determine the structure-activity relationships. The most potent inhibitor, 7, with a 5-bromopyridinyl group, had an IC(50) value of 80nM. In addition, the binding mode of a novel analog, 19, with the 4-hydroxyquinolinone moiety, was explored by molecular docking, suggesting a new interaction in the S1 pocket.

Autologous Paracrine Prostasin-Matriptase Serine Protease Interaction in Lymphoid Cancer Cells.

Project description:The serine protease prostasin on the surface of the exosomes released from epithelial cells can interact with ectopically over-expressed cell-surface serine protease matriptase in cancerous B cells to initiate the prostasin-matriptase proteolytic activation cascade. Matriptase activation and the ensuing self-activation result in its removal from cancer cells, reducing cell proliferation and migration. In this study, we tested the hypothesis that the matriptase in the lymphoid cells could be removed by the prostasin-initiated activation and self-activation using genetically engineered autologous cells carrying prostasin. In co-cultures with the prostasin-positive cells, the matriptase on the prostasin-negative vector-control cells was removed in a dose-dependent manner, as determined by flow cytometry. This paracrine phenotype requires the active sites of both proteases. In silico analysis of the RNA-seq profiles indicated an imbalanced expression of high matriptase and low prostasin, and their cognate protease inhibitors in B-cell lymphoma patient specimens. The impact of exosomal prostasin on the cluster of differentiation molecules in activated human peripheral blood mononuclear cells was investigated by flow cytometry, revealing candidate mechanisms for prostasin's role in regulating cellular adaptive immunity. This autologous paracrine prostasin-matriptase interaction could be exploited as a method for targeting over-expressed matriptase in diseases such as B-cell lymphoma.

Canonical or noncanonical? Structural plasticity of serine protease-binding loops in Kunitz-STI protease inhibitors.

Project description:The Kunitz-Soybean Trypsin Inhibitor (Kunitz-STI) family is a large family of proteins with most of its members being protease inhibitors. The versatility of the inhibitory profile and the structural plasticity of these proteins, make this family a promising scaffold for designing new multifunctional proteins. Historically, Kunitz-STI inhibitors have been classified as canonical serine protease inhibitors, but new inhibitors with novel inhibition mechanisms have been described in recent years. Different inhibition mechanisms could be the result of different evolutionary pathways. In the present work, we performed a structural analysis of all the crystallographic structures available for Kunitz-STI inhibitors to characterize serine protease-binding loop structural features and locations. Our study suggests a relationship between the conformation of serine protease-binding loops and the inhibition mechanism, their location in the β-trefoil fold, and the plant source of the inhibitors. The classical canonical inhibitors of this family are restricted to plants from the Fabales order and bind their targets via the β4-β5 loop, whereas serine protease-binding loops in inhibitors from other plants lie mainly in the β5-β6 and β9-β10 loops. In addition, we found that the β5-β6 loop is used to inhibit two different families of serine proteases through a steric blockade inhibition mechanism. This work will help to change the general perception that all Kunitz-STI inhibitors are canonical inhibitors and proteins with protease-binding loops adopting noncanonical conformations are exceptions. Additionally, our results will help in the identification of protease-binding loops in uncharacterized or newly discovered inhibitors, and in the design of multifunctional proteins.
