A high-nuclearity nickel-substituted polyoxotungstate, Na6K5.5H4.5{[Ni-8(OH)(6)(H2O)(2)](CO3)(3)(SiW9O34)(2)}center dot 22H(2)O (1), has been obtained by the reaction of Na-10[alpha-SiW9O34]center dot 18H(2)O, Ni(NO3)(2)center dot 6H(2)O and K(2)CO(3)in aqueous solution and characterized by IR spectroscopy, single crystal X-ray diffraction, thermal gravimetric analysis and elemental analysis. Carbonate is not only used to adjust the pH of the solution, but also is a structure-stabilizing agent. The polyoxoanion {[Ni-8(OH)(6)(H2O)(2)](CO3)(3)(SiW9O34)(2)}(16-)(1a) can be regarded as two {[Ni-4(OH)(3)(H2O)](SiW9O34)} subunits connected by three carbonate groups, which represents the first polyanion containing an octanuclear nickel cluster based on trivacant Keggin-type polyoxotungstate {XW9} (X = heteroatom). The subunit {[Ni-4(OH)(3)(H2O)](SiW9O34)} can be viewed as a tetranuclear nickel cluster linked to a trivacant Keggin-type polyoxotungstate {SiW9O34}. Furthermore, magnetic measurements show that1exhibits antiferromagnetic interactions.

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.

TB continues to be a leading health threat despite the availability of powerful anti-TB drugs. We report herein the design and synthesis of various hybrid molecules comprising pyrazine scaffold and various formerly identified anti-mycobacterial moieties. Thirty-one compounds were screened in vitro for their activity against Mycobacterium tuberculosis H37Rv strain using MABA assay. The results revealed that six compounds (8a, 8b, 8c, 8d, 14b and 18) displayed significant activity against Mtb with MIC values <= 6.25 mu g/ml versus 6.25 mu g/ml for pyrazinamide. The most active compounds were then assessed for their in vitro cytotoxicity against PBMC normal cell line using MTT assay and showed SI > 200. Several in silico studies have been carried out for target fishing of the novel compounds such as shape-based similarity, pharmacophore mapping and inverse docking. Based on this multi-step target fishing study, we suggest that pantothenate synthetase could be the possible target responsible for the action of these compounds. The most active compounds were then successfully docked into the active site of pantothenate synthetase enzyme with favorable binding interactions. In addition, in silico prediction of physicochemical, ADMET and drug-like properties were also determined indicating that compounds 8b, 8c and 8d are promising candidates for the development of new anti-TB agents with enhanced activity and better safety profile.

Name: Pyrazine-2-carboxylic acid. I found the field of Chemistry very interesting. Saw the article Factors affecting the metal-enhanced luminescence of lanthanide complexes by Ag@SiO2 nanoparticles published in 2020, Reprint Addresses Zhang, HX; Zhao, YL (corresponding author), Inner Mongolia Univ, Coll Chem & Chem Engn, Hohhot 010021, Peoples R China..

Metal-enhanced luminescence (MEL) via Ag@SiO2 nanoparticles provides a promising strategy for the superior luminescence of lanthanide complexes. However, because of the delicate structure of the composites of Ag@SiO2 and complexes, it remains a great challenge to achieve the ideal MEL effect. Herein, five types of Ag@SiO2 nanoparticles with distinct core sizes (100 and 46 nm) and varied silica shell thickness (3, 24, 32, 52 and 55 nm) were prepared. Four kinds of lanthanide complexes RE(BA)(3)center dot H2O and RE(pyca)(3)center dot 2H(2)O (RE = Eu and Tb, BA = benzoate, pyca = 2-pyrazine carboxylate) were synthesized. A series of REL3-Ag@SiO2 (L = BA(-), pyca(-)) composite nanoparticles were prepared through the interaction of the Ag@SiO2 nanoparticles and the complexes. The adsorption of the complexes on the surface of Ag@SiO2 nanoparticles was confirmed by transmission electron microscope and energy dispersive X-ray spectroscopy. Luminescence property investigation showed that the factors affecting the MEL effect included the excitation and emission wavelength of lanthanide complexes, the kinds of lanthanide ions and organic ligands, as well as the core size and shell thickness of Ag@SiO2. Among these factors, the excitation wavelength of lanthanide complexes and the SiO2 shell thickness were found to play decisive roles. Finally, 25.92 times enhancement in luminescent intensity and 7.4 times increase in luminescence quantum yield can be achieved on Tb(BA)(3)center dot H2O by Ag@SiO2 with core size of 46 nm and shell thickness of 24 nm.

A series of novel 2-substituted benzimidazole and benzoxazole derivatives as a potential antimicrobial and antioxidant agent were synthesized via coupling of N-methyl-o-phenylenediamine or 2-amino-phenol with aromatic aldehyde and acid in the presence of polyphosphoric acid as an efficient catalyst as well as solvent by conventional method in short reaction times with excellent yield. The newly synthesized benzimidazole and benzoxazole derivatives were evaluated for antimicrobial and antioxidant activity and exhibited excellent to good activities compared to the standard drugs. Furthermore, the theoretical predictions based on molecular docking against microbial DNA gyrase could provide an insight into the plausible mechanism of action and establish a link between the observed antimicrobial activity and the binding affinity shedding light on specific thermodynamic (bonded and nonbonded) interactions governing the activity. Furthermore, the synthesized compounds were analyzed for absorption, distribution, metabolism, and excretion properties and exhibited potential properties to build up as good oral drug candidates.

Directed C-H functionalization has been realized as a complementary tool to the traditional approaches for a straightforward access of non-proteinogenic amino acids; albeit such a process is restricted mostly up to the gamma-position. In the present work, we demonstrate the diverse (hetero) arylation of amino acids and analogous aliphatic amines selectively at the remote delta-position by tuning the reactivity controlled by ligands. An organopalladium delta-C(sp(3))-H activated intermediate has been isolated and crystallographically characterized. Mechanistic investigations carried out experimentally in conjunction with computational studies shed light on the difference in the mechanistic picture depending on the substrate structure.

Leishmaniasis being one of the six major tropical diseases that affects nearly 0.7-1.3 million people annually, has so far limited and high toxic therapeutic options. Herein, we report the synthesis, in silico, and in vitro evaluations of novel coumarin-incorporated isatin hydrazones (Spf-1 – Spf-10) as highly potent and safe antileishmanial agents. Molecular docking was initially carried out to decipher the binding confirmation of lead molecules towards the active cavity of the target protein (Leishmanolysin gp63) of Leishmania tropica. Among all the docked compounds, only Spf-6, Spf-8, and Spf-10 showed high binding affinities due to a pattern of strong conventional hydrogen bonds and hydrophobic pi-interactions. The molecular dynamics simulations showed the stable pattern of such bonding and structure-based confirmation with a time scale of 50 ns towards the top compound (Spf-10) and protein. These analyses affirmed the high stability of the system. Three out of ten compounds evaluated for their antileishmanial activity against Leishmania tropica promastigotes and amastigotes were found to be active at micromolar concentrations (IC50 range 0.1-4.13 mu mol/L), and most importantly, they were also found to be highly biocompatible when screened for their toxicity in human erythrocytes.
