Pyrazinamide (PZA) susceptibility testing in Mycobacterium tuberculosis (Mtb) is a current area of development and PZA-resistant strains are increasingly prevalent. Previous studies have demonstrated that the detection of pyrazinoic acid (POA), the metabolite produced by the deamidation of PZA, is a good predictor for PZA resistance since a resistant strain would not convert PZA into POA at a critical required rate, whereas a susceptible strain will do, expelling POA to the extracellular environment at a certain rate, and allowing for quantification of this accumulated analyte. In order to quantify POA, an indirect competitive ELISA (icELISA) test using hyperimmune polyclonal rabbit serum against POA was developed: for this purpose, pure POA was first covalently linked to the highly immunogenic Keyhole Limpet Hemocyanine, and inoculated in rabbits. A construct made of bovine serum albumin (BSA) linked to pure POA and fixed at the bottom of wells was used as a competitor against spiked samples and liquid Mtb culture supernatants. When spiked samples (commercial POA alone) were analyzed, the half maximal inhibitory concentration (IC50) was 1.16 mg/mL, the limit of detection 200 mu g/mL and the assay was specific (it did not detect PZA, IC50 > 20 mg/mL). However, culture supernatants (7H9-OADC-PANTA medium) disrupted the competition and a proper icELISA curve was not obtainable. We consider that, although we have shown that it is feasible to induce antibodies against POA, matrix effects could damage its analytical usefulness; multiple, upcoming ways to solve this obstacle are suggested.

A set of new salts containing benzimidazole and pyrazine groups, namely, [HPZBI]X-+(-) nH(2)O (X = Cl (n = 1) (1), NO3 (n = 1) (2), ClO4 (n = 0) (3) and H2PO4 (n = 0) (4)) [PZBI = 2-(pyrazin-2-yl)-1H-benzimidazole], were obtained by the reaction of PZBI and a set of inorganic acid, respectively. The emission maxima can be found at 444, 472, 471, 432 and 443 nm for PZBI and its compounds 1-4 in the solid state at room temperature, respectively. Compared with the free PZBI, the emission maxima of compounds 1-4 are obviously blue/red-shifted for 1-4, indicating that the emission maxima are relative to the intermolecular packing distances. Their photoluminescent lifetime and quantum yield are 1.10 ns and 24.5% for 1, 0.99 ns and 26.4% for 2, 0.94 ns and 21.65% for 3, 2.86 ns and 20.57% for 4, respectively. Compounds 1-4 were structurally characterized by X-ray single crystal diffraction, FT-IR, and UV-Vis spectra. Single crystal X-ray diffraction reveals that pi center dot center dot center dot pi packing interactions and a set of hydrogen bonds can be observed. The shortest distances of pi center dot center dot center dot pi stacking interactions are 3.613, 3.534, 3.731 and 3.492 angstrom in compounds 1-4, respectively. Additionally, the thermal stabilities of compounds 1-4 were investigated in detail.

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 tuning effect of C3-ester groups on the glycosylation stereochemistry of L-rhamnopyranose (L-Rha) ethyl thioglycoside donors is described. On one hand, the L-Rha thioglycoside donors carrying 3-O-arylcarbonyl or levulinoyl group undergo highly alpha-selective glycosylation to afford a wide variety of alpha-L-rhamnoside products in high chemical yields. On the other hand, the glycosylation of the 3-O-4-nitropicoloyl and 2-pyrazinecarbonyl group substituted L-Rha thioglycosides displays beta-stereoselectivity. Only or predominant beta anomeric products are obtained when these L-Rha donors couple with the primary or reactive secondary acceptors, while the beta-selectivity may decrease significantly when these donors react with less reactive secondary alcohols. The synthetic utility of the newly developed alpha- and beta-directing L-Rha donors 1h and 1e has been demonstrated by the efficient synthesis of a structurally unique trisaccharide 9, which is derived from the cell wall polysaccharide of Sphaerotilus natans.

We utilized synthetic photochemistry to generate novel sp 3 -rich scaffolds and report the design, synthesis, and biological testing of a diverse series of amides based on the 1-(amino-methyl)-2-benzyl-2-azabicyclo[2.1.1]hexane scaffold. Preliminary antimalarial screening of the library provided promising compounds with activity in the 1-5 mu M range with an enhanced hit rate. Further evaluation (solubility, drug metabolism and pharmacokinetics (DMPK), and toxicity) of a selected compound (9) suggested that this series represents an excellent opportunity for further optimization with the framework offering multiple opportunities for the addition of uniquely vectorally positioned extra functionality.

I found the field of Chemistry very interesting.

The nature of the attractive intermolecular C-H horizontal ellipsis H-C interaction, which could affect the crystal packing and solid-state molecular structure, is yet unknown. Here, a novel mercury (II) complex including N-(2-biphenyl)pyrazine-2-carboxamide ligand, one such system, has been synthesized and characterized by a single crystal X-ray diffraction. The existence of attractive intermolecular C-HMIDLINE HORIZONTAL ELLIPSISH-C interaction (-2.64 to -9.30 kj/mol depending on computational levels) is a notable feature in the crystal packing of this complex, which is the first observation of intermolecular C-HMIDLINE HORIZONTAL ELLIPSISH-C interaction in a metal complex. From crystallographic data, this contact has a distance of 2.172 angstrom which is 9.5% shorter than the sum of the van der Waals radii of two hydrogen atoms, which is the primary condition of having intermolecular interactions. We study the nature C-H horizontal ellipsis H-C interaction in the synthesized mercury (II) complex using periodic/non-periodic density functional theory in conjunction with quantum theory of atoms in molecules, non-covalent interaction reduced density gradient method, natural bond orbital, and energy decomposition analysis tools. Our results suggest that C-HMIDLINE HORIZONTAL ELLIPSISH-C interaction has closed-shell, donor-acceptor, and van der Waals nature.

A series of heteroleptic, neutral iridium(III) complexes of the form [Ir(L)(2)(N boolean AND O)] (where L = cyclometalated 2,3-disubstituted quinoxaline and N boolean AND O = ancillary picolinate or pyrazinoate) are described in terms of their synthesis and spectroscopic properties, with supporting computational analyses providing additional insight into the electronic. properties. The 10 [Ir(L)(2)(N boolean AND O)] complexes were characterized using a range of analytical techniques (including H-1, C-13, and F-19 NMR and IR spectroscopies and mass spectrometry). One of the examples was structurally characterized using X-ray diffraction. The redox properties were determined using cyclic voltammetry, and the electronic properties were investigated using UV-vis, time-resolved luminescence, and transient absorption spectroscopies. The complexes are phosphorescent in the red region of the visible spectrum (lambda(em) = 633-680 nm), with lifetimes typically of hundreds of nanoseconds and quantum yields ca. 5% in aerated chloroform. A combination of spectroscopic and computational analyses suggests that the long-wavelength absorption and emission properties of these complexes are strongly characterized by a combination of spin-forbidden metal-to-ligand charge-transfer and quinoxaline-centered transitions. The emission wavelength in these complexes can thus be controlled in two ways: first, substitution of the cyclometalating quinoxaline ligand can perturb both the highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital levels (LUMO, Cl atoms on the ligand induce the largest bathochromic shift), and second, the choice of the ancillary ligand can influence the HOMO energy (pyrazinoate stabilizes the HOMO, inducing hypsochromic shifts).

Several dehydroabietylamine derivatives containing heterocyclic moieties such as thiophene and pyrazine ring were successfully synthesized. The antiproliferative activities of these thiophene-based Schiff-bases, thiophene amides, and pyrazine amides were investigated in vitro against Hela (cervix), MCF-7 (breast), A549 (lung), HepG2 (liver), and HUVEC (umbilical vein) cells by MTT assay. The toxicity of L-1-L-10 (IC50 = 5.92- >100 mu M) was lower than L-0 (1.27 mu M) and DOX (4.40 mu M) in every case. Compound L-1 had higher anti-HepG2 (0.66 mu M), anti-MCF-7 (5.33 mu M), and anti-A549 (2.11 mu M) and compound L-3 had higher anti-HepG2 (1.63 mu M) and anti-MCF-7 (2.65 mu M) activities. Both of these compounds were recognized with high efficiency in apoptosis induction in HepG2 cells and intercalated binding modes with DNA. Moreover, with average IC50 values of 0.66 and 5.98 mu M, L-1 was nine times more effective at suppressing cultured HepG2 cells viability than normal cells (SI = 9). The relative tumor proliferation rate (T/C) was 38.6%, the tumor inhibition rate was up to 61.2%, which indicated that L-1 had no significant toxicity but high anti-HepG2 activity in vivo. Thus, it may be a potential antiproliferation drug with nontoxic side effects.

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.
