Diazinecarboxylic acids (pyridazine-3-carboxylic, pyridazine-4-carboxylic, pyrimidine-2-carboxylic, pyrimidine-4-carboxylic, pyrimidine-5-carboxylic and pyrazine-2-carboxylic acids) were characterized by means of spectroscopic (FT-Raman, FTIR, UV, (HNMR)-H-1, (CNMR)-C-13) and thermogravimetric analysis as well as antimicrobial and cytotoxic tests. The structures of diazinecarboxylic acids were calculated by the DFT method (B3LYP/6-311G(d, p). For the most stable conformers, the energy of HOMO and LUMO molecular orbitals, the geometric (HOMA, GEO, EN, I6) and magnetic (NICS) aromaticity indices, NBO electronic charge distribution, sEDA and pEDA indexes, Wiberg Bond Order, Wiberg Index and theoretical IR and NMR spectra have been calculated. The energies of protonating and deprotonating acids were also calculated. The effect of the nitrogen heteroatom position in the aromatic ring in relation to the position of the carboxyl group on the electronic charge distribution, thermal stability, antimicrobial and cytotoxicity activities of the examined acids was determined. Antimicrobial activity of tested acids against of Escherichia coli, Bacillus subtilis, Pseudomonas aeruginosaand Candida albicanswas calculated based on MTT colorimetric assay (MCA). The cytotocic effect of diazynecarboxylic acids was examined in A375 melanoma cell line and DLD-1 cell line. A biplot analysis was performed in order to determine the correlations between selected parameters of the tested compounds and relative cell viability of E. coli, B. subtilis, P. aeruginosa, C. albicans, A375 and DLD-1 cell lines. Thermal behaviour of all investigated carboxylic acids was investigated using thermogravimetry (TG) and differential scanning calorimetry (DSC) techniques in flowing air atmosphere. All compounds are stable in room temperature. (C) 2021 Elsevier B.V. All rights reserved.

Myocardial infarction (MI) injury is a highly lethal syndrome that has, until recently, suffered from a lack of clinically efficient targeted therapeutics. The cardiac troponin I interacting kinase (TNNI3K) exacerbates ischemia-reperfusion (IR) injury via oxidative stress, thereby promoting cardiomyocyte death. In this current study, we designed and synthesized 35 novel TNNI3K inhibitors with a pyrido[4,5]thieno [2,3-d] pyrimidine scaffold. In vitro results indicated that some of the inhibitors exhibited sub-micromolar TNNI3K inhibitory capacity and good kinase selectivity, as well as cytoprotective activity, in an oxygen-glucose deprivation (OGD) injury cardiomyocyte model. Furthermore, investigation of the mechanism of the representative derivative compound 6o suggested it suppresses pyroptosis and apoptosis in cardiomyocytes by interfering with p38MAPK activation, which was further confirmed in a murine myocardial infarction injury model. In vivo results indicate that compound 6o can markedly reduce myocardial infarction size and alleviate cardiac tissue damage in rats. In brief, our results provide the basis for further development of novel TNNI3K inhibitors for targeted MI therapy. (C) 2020 Elsevier Masson SAS. All rights reserved.

A universally applicable method for the prediction of the isobaric heat capacities of the liquid and solid phase of molecules at 298.15 K is presented, derived from their true volume. The molecules’ true volume in A(3) is calculated on the basis of their geometry-optimized structure and the Van-der-Waals radii of their constituting atoms by means of a fast numerical algorithm. Good linear correlations of the true volume of a large number of compounds encompassing all classes and sizes with their experimental liquid and solid heat capacities over a large range have been found, although noticeably distorted by intermolecular hydrogen-bond effects. To account for these effects, the total amount of 1303 compounds with known experimental liquid heat capacities has been subdivided into three subsets consisting of 1102 hydroxy-group-free compounds, 164 monoalcohols/monoacids, and 36 polyalcohols/polyacids. The standard deviations for Cp(liq,298) were 20.7 J/mol/K for the OH-free compunds, 22.91 J/mol/K for the monoalcohols/monoacids and 16.03 J/mol/K for the polyols/polyacids. Analogously, 797 compounds with known solid heat capacities have been separated into a subset of 555 OH-free compounds, 123 monoalcohols/monoacids and 119 polyols/polyacids. The standard deviations for Cp(sol,298) were calculated to 23.14 J/mol/K for the first, 21.62 J/mol/K for the second, and 19.75 J/mol/K for the last subset. A discussion of structural and intermolecular effects influencing the heat capacities as well as of some special classes, in particular hydrocarbons, ionic liquids, siloxanes and metallocenes, has been given. In addition, the present method has successfully been extended to enable the prediction of the temperature dependence of the solid and liquid heat capacities in the range between 250 and 350 K.

Pyrazinecarboxylic acid (PCA) was examined as a potential corrosion inhibitor for mild steel (MS) in 0.5 M HCl environment. The methods of electrochemical impedance spectroscopy (EIS), linear polarization resistance (LPR), as well potentiodynamic (PD) polarization were utilized. Furthermore, atomic force microscopy (AFM) and quantum chemical calculations were utilized. PD polarization curves demonstrated that PCA exhibited mixed inhibitor behavior. Scanning electron microscopy (SEM) offered the creation of an adsorptive layer on the surface of MS which prevented the steel against corrosive specimens. Furthermore, density functional theory (DFT) presented good agreement with electrochemical experimental results. The adsorption equilibrium constant (k(ads)) value was calculated to be 3.704 x 10(4) M-1 which was related to a high proportion of inhibitor on the surface. In the presence of 1.0 mM PCA, inhibition efficiency was determined as 95.2% from EIS results.

A number of pantoprazole derivatives were synthesized and screened for their urease inhibitory properties. Some of them showed potent inhibitions against jack bean urease. All compounds showed varying degree of IC50 in the range of 25.85 to 181 mu Mol as compared to standard acetohydroxamic acid (AHA) (100 +/- 2.02 mu Mol). Derivatives bearing 5-aryl-1,3,4-oxadiazole ring substitutions (aryl= pyrazyl, pyridyl and phenyl) were found to be more potent inhibitors than AHA and pantoprazole. The most promising compound, 2-((3,4-dimethoxypyridin-2-yl)methylthio)-5-(pyrazin-2-yl)-1,3,4-oxadiazole 12, with IC50 value of 25.85 +/- 1.21 showed remarkable urease inhibition activity. In silico molecular modeling investigation performed to rationalize the possible binding interaction and ADME properties of compounds over the active site of urease enzyme. The induced fit docking study showed that compound 12 interacted with conserved residues His593 and Arg609 located at the mouth of the urease active site flap and are essential for enzyme catalytic activity. These target compounds could be further studied as a lead skeleton for discovery of novel urease inhibitors.

Background and ObjectivesPyrazinamide, a drug used in the regimen for the treatment of drug-sensitive tuberculosis, is also used for the treatment of multidrug-resistant tuberculosis (MDR-TB). We aimed to describe the population pharmacokinetics of pyrazinamide and its major metabolite, pyrazinoic acid, in patients with MDR-TB and characterise the effects of demographic variables.MethodsThis was a non-randomised clinical study involving 51 adult patients admitted for the intensive phase of MDR-TB treatment. Blood samples were collected at pre-dose and at 0.5, 1, 1.5, 2, 3, 4, 8, 16 and 24h after drug administration. Plasma concentrations of pyrazinamide and pyrazinoic acid were analysed using a validated LC-MS/MS method. Nonlinear mixed-effects modelling using Monolix 2018R1 software was employed to estimate population pharmacokinetic parameters.ResultsA one-compartment pharmacokinetic model with transit compartment absorption process and first-order elimination best described the pyrazinamide and pyrazinoic acid concentration-time data. The estimated population pharmacokinetic parameters were 0.7h, 3.38h(-1), 57.1l, 4.37L/h and 10.5L/h for mean transit time, absorption rate constant, apparent distribution volume for pyrazinamide, and apparent clearance for pyrazinamide and pyrazinoic acid (CLm/F), respectively. These parameters were not affected by patient age, HIV status or sex. The parameter variability in CLm/F was the highest (83.5%), while the rest of the parameters ranged from 16.2 to 58%.ConclusionsThe developed population pharmacokinetic model adequately described the disposition of pyrazinamide and pyrazinoic acid and can be useful for dose determination of pyrazinamide in patients with MDR-TB.

Pyrazinamide has been a mainstay in the multidrug regimens used to treat tuberculosis. It is active against the persistent, non-replicating mycobacteria responsible for the protracted therapy required to cure tuberculosis. Pyrazinamide is a pro-drug that is converted into pyrazinoic acid (POA) by pyrazinamidase, however, the exact target of the drug has been difficult to determine. Here we show the enzyme PanD binds POA in its active site in a manner consistent with competitive inhibition. The active site is not directly accessible to the inhibitor, suggesting the protein must undergo a conformational change to bind the inhibitor. This is consistent with the slow binding kinetics we determined for POA. Drug-resistant mutations cluster near loops that lay on top of the active site. These resistant mutants show reduced affinity and residence time of POA consistent with a model where resistance occurs by destabilizing the closed conformation of the active site. The important tuberculosis drug pyrazinamide (PZA) is converted to its active form pyrazinoic acid (POA) in Mycobacterium tuberculosis (Mtb). Here the authors identify the pantothenate biosynthesis pathway enzyme aspartate decarboxylase (PanD) as the target of PZA and determine the POA bound Mtb PanD crystal structure.

Pyrazinamide is an important first-line drug used in shortening TB therapy. In our current work, a series of novel substituted-N-(6-(4-(pyrazine-2-carbonyl)piperazine/homopiperazine-1-yl)pyridin-3-yl)benzamide derivatives were designed, synthesized, and evaluated for their anti-tubercular activity against Mycobacterium tuberculosis H37Ra. Among the tested compounds, five compounds (6a, 6e, 6h, 6j and 6k) from Series-I and one compound (7e) from Series-II exhibited significant activity against Mycobacterium tuberculosis H37Ra with 50% inhibitory concentrations (IC50) ranging from 1.35 to 2.18 mu M. To evaluate the efficacy of these compounds, we examined their IC90 values. Five of the most active compounds were found to be more active with IC(90)s ranging from 3.73 to 4.00 mu M and one compound (6e) showed an IC90 of 40.32 mu M. Moreover, single crystals were developed for 6d, 6f and 6n. In addition, most active compounds were evaluated for their cytotoxicity on HEK-293 (human embryonic kidney) cells. Our results indicate that the compounds are nontoxic to human cells. The molecular interactions of the derivatised conjugates in docking studies reveal their suitability for further development.
