Acylpeptide hydrolase is a serine protease, which, together with prolyl oligopeptidase, dipeptidyl peptidase IV and oligopeptidase B, belongs to the prolyl oligopeptidase family. Its primary function is associated with the removal of N-acetylated amino acid residues from proteins and peptides. Although the N-acylation occurs in 50-90 % of eukaryotic proteins, the precise functions of this modification remains unclear. Recent findings have indicated that acylpeptide hydrolase participates in various events including oxidized proteins degradation, amyloid beta-peptide cleavage, and response to DNA damage. Considering the protein degradation cycle cross-talk between acylpeptide hydrolase and proteasome, inhibition of the first enzyme resulted in down-regulation of the ubiquitin-proteasome system and induction of cancer cell apoptosis. Acylpeptide hydrolase has been proposed as an interesting target for the development of new potential anticancer agents. Here, we present the synthesis of simple derivatives of (1-aminoethyl)phosphonic acid diaryl esters, phosphonic analogs of alanine diversified at the N-terminus and ester rings, as inhibitors of acylpeptide hydrolase and discuss the ability of the title compounds to induce apoptosis of U937 and MV-4-11 tumor cell lines.

NLRP3 inflammasomes have recently emerged as an attractive drug target for neurodegenerative disorders. In our continuing studies, a new chemical scaffold was designed as selective inhibitors of NLRP3 inflammasomes. Initial characterization of the lead HL16 demonstrated improved, however, nonselective inhibition on the NLRP3 inflammasome. Structure-activity relationship studies of HL16 identified a new lead, 17 (YQ128), with an IC50 of 0.30 +/- 0.01 mu M. Further studies from in vitro and in vivo models confirmed its selective inhibition on the NLRP3 inflammasome and its brain penetration. Furthermore, pharmacokinetic studies in rats at 20 mg/kg indicated extensive systemic clearance and tissue distribution, leading to a half-life of 6.6 h. However, the oral bioavailability is estimated to be only 10%, which may reflect limited GI permeability and possibly high first-pass effects. Collectively, these findings strongly encourage development of more potent analogues with improved pharmacokinetic properties from this new chemical scaffold.

In this work, we present a simple, two-stage method for the preparation of new and efficient antimicrobial hybrid systems, based on isoniazid and pyrazine-2-carbohydrazide tuberculostatic agents covalently linked to graphene oxide. In the first step, the carboxyl groups of graphene oxide are activated by transforming them into the corresponding acid chloride groups, which, in the second step, will react with the amino groups of the two drugs. Pyrazine-2-carbohydrazide was obtained from pyrazinoic acid and hydrazine hydrate and was confirmed by nuclear magnetic resonance spectroscopy. The materials have been characterized by elemental analysis, infrared spectroscopy, Raman spectroscopy, scanning electron microscopy, and X-ray photoelectron spectroscopy. Their antimicrobial activity was tested on mycobacterial (Mycobacterium terrae), as well as on Gram-negative bacteria (Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATCC 27853), Gram-positive bacteria (Staphylococcus aureus ATCC 6538, Staphylococcus aureus ATCC 25923) and fungal (Candida albicans ATCC 10231), in planktonic and biofilm growth state. The biocompatibility of the tested compounds was assessed in vitro by live-dead fluorescence staining and flow cytometry. The results of this study have shown that the functionalization of graphene oxide with isoniazid and pyrazine-2-carbohydrazide both enhanced the anti-mycobacterial activity of the respective drugs and extended their antimicrobial spectrum towards other microbial strains, in planktonic and biofilm growth state, showing a promising potential for mitigating the impact of antimicrobial resistance and the deleterious effects of microbial biofilms. At the active tuberculostatic concentrations, the tested compounds exhibit very low cytotoxicity and do not interfere with the cellular cycle of Hep-2 cells. The flow cytometry and live/dead fluorescence staining proved that the tested compounds exhibit a microbicidal effect through induction of cellular lesions, consecutive to membrane depolarization.

Discovery and development of new therapeutic options for the treatment of Mycobacterium tuberculosis (Mtb) infection, particularly drug-resistant strains, are urgently required to tackle the global burden of this disease. Herein, we reported the synthesis of a novel series of N-substituted amino acid hydrazides, utilising a scaffold hopping approach within a library of anti-tubercular agents. Efficacy and selectivity were evaluated against three strains of Mtb (wild-type, isoniazid-resistant and rifampicin-resistant), and cytotoxicity against macrophages in vitro. The antibacterial activity and therapeutic index of these molecules were significantly affected by modifications with the N-substituents. Introduction of a 3,5-dinitroaryl moiety demonstrated enhanced antibacterial activity against all three strains of Mtb. In contrast, the inclusion of an imidazo [1,2-a]pyridine-3-carboxy moiety resulted in enhanced activity towards isoniazid mono-resistant Mtb relative to wild-type Mtb. Consequently, this scaffold hopping approach showed significant promise for exemplification of novel molecules with specific activity profiles against drug-resistant tuberculosis.

The Yamaguchi reaction is widely and generally applied to synthesize esters and lactones. It involves 2,4,6-trichlorobenzoyl chloride as the Yamaguchi reagent, 4-dimethylaminopyridine, and triethylamine. Pyrazinamide is a crucial first-line drug for tuberculosis treatment, therefore their analogues are interesting in organic synthesis. In general, the synthesis pyrazinamide analogues involve reaction of pyrazine-2-carboxylic acids with thionyl chloride to yield the corresponding acyl chlorides, which on treatment with amines gave pyrazine-2-carboxamides. However, thionyl chloride is listed under the Chemical Weapons Convention and releases toxic sulfur oxide when react with carboxylic acid. We successfully synthesized series of pyrazinamide analogues using the Yamaguchi reaction. The synthesis involved reaction of pyrazine-2-carboxylic acid with various aliphatic and aromatic amines in the presence of Yamaguchi reagent and 4-dimethylaminopyridine. The yield of the pyrazine-2-carboxamides and the reaction time depended on the type of the amine (aliphatic vs aromatic), substitution pattern, and number of substituents on the aromatic amines.N-(4-chlorophenyl)pyrazine-2-carboxamides can be prepared by this method in 81% yield;N-(2-ethylhexyl)pyrazine-2-carboxamide andN-(4-fluorobenzyl)pyrazine-2-carboxamide showed the best activity againstMycobacterium tuberculosisH37Rv (<6.25 mu g/mL). This result could lead to find more active pyrazinamide analogues.

The P2Y(14) receptor (P2Y(14)R) plays a key role in the modulation of inflammatory process, but very few classes of antagonists have been reported. A series of 3-amide benzoic acid derivatives were identified as novel and potent P2Y(14)R antagonists. The most potent antagonist, 16c, showed comparable activity (IC50 = 1.77 nM) to PPTN, the most potent P2Y(14)R antagonist reported. Compound 16c demonstrated dramatically improved aqueous solubility and excellent metabolic stability in rat and human microsomes. Investigation of the anti-inflammatory effect of 16c was performed in MSU treated THP-1 cells by flow cytometry, Western Blot and immunofluorescence labeling technology, which exhibited that 16c might be a promising candidate for further research.

Caseinolytic protease P (ClpP) is considered as a promising target for the treatment of Staphylococcus aureus infections. In an unbiased screen of 2632 molecules, a peptidomimetic boronate, MLN9708, was found to be a potent suppressor of SaClpP function. A time-saving and cost-efficient strategy integrating in silico position scanning, multistep miniaturized synthesis, and bioactivity testing was deployed for optimization of this hit compound and led to fast exploration of structure-activity relationships. Five of 150 compounds from the miniaturized synthesis exhibited improved inhibitory activity. Compound 43Hf was the most active inhibitor and showed reversible covalent binding to SaClpP while did not destabilize the tetradecameric structure of SaClpP. The crystal structure of 43Hf-SaClpP complex provided mechanistic insight into the covalent binding mode of peptidomimetic boronate and SaClpP. Furthermore, 43Hf could bind endogenous ClpP in S. aureus cells and exhibited significant efficacy in attenuating S. aureus virulence in vitro and in vivo.

The B3NO2 six-membered heterocycle (1,3-dioxa-5-aza-2,4,6-triborinane = DATB), comprising three different non-carbon period 2 elements, has been recently demonstrated to be a powerful catalyst for dehydrative condensation of carboxylic acids and amines. The tedious synthesis of DATB, however, has significantly diminished its utility as a catalyst, and thus the inherent chemical properties of the ring system have remained virtually unexplored. Here, a general and facile synthetic strategy that harnesses a pyrimidine-containing scaffold for the reliable installation of boron atoms is disclosed, giving rise to a series of Pym-DATBs from inexpensive materials in a modular fashion. The identification of a soluble Pym-DATB derivative allowed for the investigation of the dynamic nature of the B3NO2 ring system, revealing differential ring-closing and -opening behaviors depending on the medium. Readily accessible Pym-DATBs proved their utility as efficient catalysts for dehydrative amidation with broad substrate scope and functional-group tolerance, offering a general and practical catalytic alternative to reagent-driven amidation.

Although pyrazinamide (PZA) is a key component of first- and second-line tuberculosis treatment regimens, there is no gold standard to determine PZA resistance. Approximately 50% of multidrug-resistant tuberculosis (MDR-TB) and over 90% of extensively drug-resistant tuberculosis (XDR-TB) strains are also PZA resistant. pncA sequencing is the endorsed test to evaluate PZA susceptibility. However, molecular methods have limitations for their wide application. In this study, we standardized and evaluated a new method, MODS-Wayne, to determine PZA resistance. MODS-Wayne is based on the detection of pyrazinoic acid, the hydrolysis product of PZA, directly in the supernatant of sputum cultures by detecting a color change following the addition of 10% ferrous ammonium sulfate. Using a PZA concentration of 800 mu g/ml, sensitivity and specificity were evaluated at three different periods of incubation (reading 1, reading 2, and reading 3) using a composite reference standard (MGIT-PZA, pncA sequencing, and the classic Wayne test). MODS-Wayne was able to detect PZA resistance, with a sensitivity and specificity of 92.7% and 99.3%, respectively, at reading 3. MODS-Wayne had an agreement of 93.8% and a kappa index of 0.79 compared to the classic Wayne test, an agreement of 95.3% and kappa index of 0.86 compared to MGIT-PZA, and an agreement of 96.9% and kappa index of 0.90 compared to pncA sequencing. In conclusion, MODS-Wayne is a simple, fast, accurate, and inexpensive approach to detect PZA resistance, making this an attractive assay especially for low-resource countries, where TB is a major public health problem.

Thorium (Th) exposure to the human beings is a radiochemical hazard and the chelation therapy by suitable drugs is the major prevention approach to deal with. The present studies aimed at usage of pyrazinoic acid (PCA), which is a prodrug to treat tuberculosis, for its usage as decorporating agent for thorium from human body. The present studies provide a comprehensive knowledge on the chemical interaction and biological efficacy of pyrazinoic acid (PCA) for decorporation of Thorium from the human body. The thermodynamic parameters for Th-PCA speciation are determined by both experiment and theory. The potentiometric data analysis and Electro-Spray Ionization Mass Spectrometry (ESI-MS) studies revealed the formation of MLi (i = 1-4) species with the decrease in stepwise stability constants. All the species formations are endothermic reactions and are predominantly entropy-driven. Biological experiments using human erythrocytes, whole blood and normal human lung cells showed cytocompatibility and decorporation ability of PCA for Thorium. Density functional calculations have been carried out to get insights on interaction process at molecular level. The experimental results and theoretical predictions found to be in line with each other. Present findings on complexation of Th by PCA and its evaluation in human cells and blood would further motivate determination of its safety levels and decorporation efficacy in animal models.
