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 tetrapeptidyl epoxyketone inhibitors of 20S proteasome was designed and synthesized. To fully understand the SAR, various groups at R-1, R-2, R-3, R-4 and R-5 positions, including aromatic and aliphatic substituents were designed, synthesized and biologically assayed. Based on the enzymatic results, seven compounds were selected to evaluate their cellular activities and soluble compound 36 showed strong potency against human multiple myeloma (MM) cell lines. Microsomal stability results indicated that compound 36 was more stable in mice, rat and human microsomes than marketed carfilzomib. The in vivo activities of this compound were evaluated with the xenograft mice models of MM cell lines ARH77 and RPMI-8226 with luciferase expression and the T/C value of the two models were 49.5% and 37.6%, respectively. To evaluate the potential cardiovascular toxicity, inhibition of hERG ion channel in HEK293 cells by compound 36 and carfilzomib was carried out. The results indicated that 36 had no binding affinity for the hERG ion channel while carfilzomib could bind it with IC50, of 92.1 mu M.

On the basis of crystal engineering, two similar esters of phenyl pyridine-2-carboxylate (I) and phenyl pyrazine-2-carboxylate (II) were designed and synthesized. The compounds were characterized using FT-IR, mass spectrometry, CHN-elemental analyses, NMR and PXRD. For each compound, two polymorphs were obtained (Ia, Ib and IIa, IIb) and identified by TGA, DSC and SCXRD. A comparison of the crystal structures of the polymorphs revealed that the different torsion angles of the pyrazine (tau(1)) and phenyl (tau(2)) rings to the ester backbone resulted in the conformers I and II, respectively. Theoretical criteria (max(Delta theta), rmsd[r]-crystal, energy profile) confirmed that the structural differences in the conformers are in the range of acceptable values for the detection of conformational changes. The phase stability of the polymorphs was investigated by slurry and grinding methods as well as by the HSM technique. Since the orientations of pyrazine and phenyl moieties were altered in the polymorphs, the hydrogen bond donor and acceptors exhibited meaningful supramolecular architectures in the crystal packing as well as C-HMIDLINE HORIZONTAL ELLIPSISN, C-HMIDLINE HORIZONTAL ELLIPSISO and C-HMIDLINE HORIZONTAL ELLIPSIS pi interactions. The energetic study of the noncovalent interactions in the molecular pairs (dimers) of the polymorph crystal structures was performed by DFT-D calculations.

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.

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).

Background Tuberculosis (TB) caused by Mycobacterium tuberculosis is one of the main killers of people all over the world. The major hurdles with existing therapy are the lengthy regimen and appearance of multi drug resistant (MDR) and extensively drug resistant (XDR) strains of M.tuberculosis. Aims The present work was aimed to synthesize and determine antitubercular and antimicrobial potential of some novel 3-chloro-4-aryl-1-[4-(5-pyrazin-2-yl[1,3,4]oxadiazole-2-ylmethoxy)-phenyl]-azetidin-2-one derivatives 7(a-h) from pyrazinoic acid as precursor, which is a well-established antitubercular agent. Here we report the synthesis of a new class of heterocyclic molecules in which pyrazine, 1, 3, 4-oxadiazole and azetidinone moieties were present in one frame work. Methods Pyrazinoic acid (1) was esterified first (2) followed by amination to produce hydrazide (3) which was refluxed with POCl3 to obtain 2-chloromethyl-5pyrazino-1, 3, 4-oxadiazole (4). This was then further reacted with 4-amino phenol to obtain 4-[5-pyrazino-1, 3, 4-oxadiazol-2-yl-methoxy]-phenyl amine (5) which on condensation with various aromatic aldehydes afforded a series Schiff’s bases 6(a-h). Dehydrative annulations of 6(a-h) in the presence of chloroacetyl chloride and triethylamine yielded 3-chloro-4-aryl-1-[4-(5-pyrazin-2-yl-[1, 3, 4]oxadiazole-2-ylmethoxy)-phenyl]-azetidin-2-one derivatives 7(a-h). Antibacterial, antifungal and antitubercular potential of all the synthesized compounds were assessed. Docking study was performed using the software VLife Engine tools of Vlifemds 4.6 on the protein lumazine synthase of M. tuberculosis (PDB entry code 2C92). Results The present studies demonstrated that synthesized oxadiazole derivatives have good antimicrobial activity against the various microorganisms. Among the synthesized derivative, 7b and 7g were found to be prominent compounds which have potential antibacterial, antifungal and antitubercular activity (with MIC 3.12 mu g/ml and high dock score ranging from -59.0 to -54.0) against Mycobacterium tuberculosis. Conclusions Derivatives 7b and 7g would be effective lead candidates for tuberculosis therapy.

A series of monometallic complexes (Ru1-3, Ir-1(-3)) which have N,O-chelating ligand (pyrazine-2carboxylate (1), pyridine-2-carboxylate (2), quinoline carboxylate(3) and bimetallic complexes (Ru-4,Ru-5, Ir-4(,5)) bridged by pyrazine-2,3- dicarboxylate (4) and imidazole-4,5-dicarboxylate(5) were synthesized and characterized by H-1-, C-13 NMR, FT-IR, and elemental analysis. The crystal structure of Ir-2 was determined by X-ray crystallography. The complexes (Ru1-5, Ir1-5) were applied to investigate the electronic and steric effect of ligand in their catalytic activities in transfer hydrogenation and alpha(alpha)-alkylation reaction of ketones with alcohols. The activities of iridium complexes (Ir1-5) were much more efficient than ruthenium complexes (Ru1-5). The highest activity for both reactions was observed for the complex (Ir2 ) with pyridine-2-carboxylate. The Ir hydride species was monitored for both reactions. (C) 2020 Elsevier B.V.

The clinical effectiveness of carbapenem antibiotics such as meropenem is becoming increasingly compromised by the spread of both metallo-beta-lactamase (MBL) and serine-beta-lactamase (SBL) enzymes on mobile genetic elements, stimulating research to find new beta-lactamase inhibitors to be used in conjunction with carbapenems and other beta-lactam antibiotics. Herein, we describe our initial exploration of a novel chemical series of metallo-beta-lactamase inhibitors, from concept to efficacy, in a survival model using an advanced tool compound (ANT431) in conjunction with meropenem.

A common strategy employed in antibacterial drug discovery is the targeting of biosynthetic processes that are essential and specific for the pathogen. Specificity in particular avoids undesirable interactions with potential enzymatic counterparts in the human host, and it ensures ontarget toxicity. Synthesis of pantothenate (Vitamine B5), which is a precursor of the acyl carrier coenzyme A, is an example of such a pathway. In Mycobacterium tuberculosis (Mtb), which is the causative agent of tuberculosis (TB), pantothenate is formed by pantothenate synthase, utilizing D-pantoate and beta-Ala as substrates. beta-Ala is mainly formed by the decarboxylation of L-aspartate, generated by the decarboxylase PanD, which is a homo-oliogomer in solution. Pyrazinoic acid (POA), which is the bioactive form of the TB prodrug pyrazinamide, binds and inhibits PanD activity weakly. Here, we generated a library of recombinant Mtb PanD mutants based on structural information and PZA/POA resistance mutants. Alterations in oligomer formation, enzyme activity, and/or POA binding were observed in respective mutants, providing insights into essential amino acids for Mtb PanD’s proper structural assembly, decarboxylation activity and drug interaction. This information provided the platform for the design of novel POA analogues with modifications at position 3 of the pyrazine ring. Analogue 2, which incorporates a bulky naphthamido group at this position, displayed a 1000-fold increase in enzyme inhibition, compared to POA, along with moderately improved antimycobacterial activity. The data demonstrate that an improved understanding of mechanistic and enzymatic features of key metabolic enzymes can stimulate design of more-potent PanD inhibitors.
