Cooperative Strong Charge-Assisted N-H center dot center dot center dot O Hydrogen Bonding and Weaker Nonconventional C-H center dot center dot center dot N Hydrogen Bonding in the Formation of Extended Hydrogen-Bonded Networks with 2,3,5,6-Tetrafluorobenzoic Acid

Cooperative strong charge-assisted hydrogen bonding and weaker nonconventional hydrogen bonding are probed through cocrystals formed between 2,3,5,6-tetrafluorobenzoic acid and three 2-aminopyrazines. In each of these cocrystals, cooperative nonconventional hydrogen bonding and charge-assisted hydrogen bonding results in the formation of hydrogen-bonded supramolecular networks. A charge-assisted cyclic hydrogen bonded motif, R-2(2)(8), is formed between the 2-aminopyrazinium cation and the carboxylate anion along with a nonconventional C-H center dot center dot center dot N hydrogen bond between the phenyl hydrogen and second ring N in the pyrazine. Secondary hydrogen bonding interactions result in the formation of a double-stranded linear polymer, a planar 2D polymer, or an interconnected 3D network depending on secondary substitution of the 2-aminopyrazine. The related formation of both 1:1 and 2:1 cocrystals between 4-pyrrolidinopyridine and 2,3,5,6-tetrafluorobenzoic acid is also reported.

Modulation of the properties of dinuclear lanthanide complexes through utilizing different beta-diketonate co-ligands: near-infrared luminescence and magnetization dynamics

A family of new dinuclear lanthanide complexes as the simplest entities showing intramolecular magnetic interactions, [Ln(2)(dbm)(2)(L)(2)(CH3OH)(2)] (Ln = Tb (1), Dy (2), Ho (3), Er (4), Yb (5), Lu (6)), [Ln(2)(acac)(2)(L)(2)(EtOH)(2)] (Ln = Dy (7), Er (8)), [Dy-2(TTA)(2)(L)(2)(CH3OH)(2)]center dot 2CH(2)Cl(2) (9) and [Dy-2(tfa)(2)(L)(2)(CH3OH)(2)] (10) (H2L = N ‘-(2-hydroxy-5-methylphenyl)-pyrazine-2-carbohydrazide, Hdbm = 1,3-diphenyl-1,3-propanedione, Hacac = acetylacetone, HTTA = 2-thenoyltrifluoroacetone, Htfa = trifluoroacetylacetone), were constructed successfully by the reaction of a Schiff base ligand H2L and four different beta-diketonate salts. As for complexes 4, 5 and 8, all exhibit the characteristic emission peaks of the corresponding Er3+, Yb3+ and Er3+ ions, respectively. Meanwhile, the excitation wavelength (510 nm) of 5 is located in the visible region, confirming its significant potential application value. Magnetic studies indicate that complexes 9 and 10 exhibit characteristic slow relaxation of magnetization with the energy barriers (U-eff) of 102 K for 9 and 140 K for 10 under a zero dc field. Under the optimized dc fields, slow magnetic relaxations are present in 2 and 7, and the U-eff values of 9 and 10 have been improved. This proves that the beta-diketonate co-ligands deserve an important role in regulating Dy-SMMs influenced by the diverse perturbations of the axial crystal field originating from minor changes in the coordination environment.

A novel hydrazide Schiff base self-assembled nanoprobe for selective detection of human serum albumin and its applications in renal disease surveillance

Human serum albumin (HSA) is considered as a biomarker for the early diagnosis of renal disease, therefore identifying and detecting HSA in biological fluids (especially urine) with an easy method is of great importance. Herein, we report a novel hydrazide Schiff base fluorescent probeN ‘-((7-(diethylamino)-2-oxo-2H-chromen-3-yl)methylene)pyrazine-2-carbohydrazide (NPC), which self-assembled into nanoparticles in aqueous solution. Based on disassembly-induced emission and the site-specific recognition mechanism, the binding ofNPCwith HSA resulted in a fluorescence turn-on response. ProbeNPCexhibited superior selectivity and sensitivity toward HSA with a detection limit of 0.59 mg L(-1)in PBS and 0.56 mg L(-1)in the urine sample. The site-binding mechanism ofNPCwith HSA was explored by fluorescence quenching study, Job’s plot analysis, HSA destruction, site marker displacement and molecular docking. Fluorescence imaging of HSA in MCF-7 cells was achieved by using a non-toxicNPCprobe, suggesting thatNPCcould be applied to visualize the level of HSAin vivo. More importantly, further practical applications of probeNPCin human urine samples were achieved with satisfactory results by using a fluorometer or test paper, which could provide extensive application in clinical diagnosis.

Theoretical study of switching characteristics of molecular tweezers based on bis(Zn-salphen)

A series of novel tweezers based on bis(Zn-salphen) complex is theoretically studied. Density functional theory (DFT) method is used to investigate the switchable properties of terpy/bis(Zn-salphen) complex (1, terpy=2,2 ‘:6 ‘,2 ”-terpyridine) and Br-phtpy/bis(Zn-salphen) complex (2, Br-phtpy=4 ‘-bromophenyl-2,2 ‘:6 ‘,2 ”-terpyridine). In this study, the free tweezers1and2can be converted from a W open form to a U closed form upon Ru(III) coordination. The switching performances were characterized by(1)H NMR and absorption spectra. DFT calculations were carried out using a B3LYP-D3 functional and def2-SVP basis set for all atoms.H-1 NMR spectra showed that terpyridine protons had an obvious upfield shift during complexation with RuCl3. The absorption spectrum was observed in the closed tweezers with a significant red shift and a decreased oscillator strength. In addition, the tweezers were reopened by introducing molecule pyrazine in the U-shaped conformation to form a host-guest system. The recognition ability of two Zn-salphen complexes was studied by geometrical optimization and absorption spectra.

5-Alkylamino-N-phenylpyrazine-2-carboxamides: Design, Preparation, and Antimycobacterial Evaluation

According to the World Health Organization, tuberculosis is still in the top ten causes of death from a single infectious agent, killing more than 1.7 million people worldwide each year. The rising resistance developed by Mycobacterium tuberculosis against currently used antituberculars is an imperative to develop new compounds with potential antimycobacterial activity. As a part of our continuous research on structural derivatives of the first-line antitubercular pyrazinamide, we have designed, prepared, and assessed the in vitro whole cell growth inhibition activity of forty-two novel 5-alkylamino-N-phenylpyrazine-2-carboxamides with various length of the alkylamino chain (propylamino to octylamino) and various simple substituents on the benzene ring. Final compounds were tested against Mycobacterium tuberculosis H37Ra and four other mycobacterial strains (M. aurum, M. smegmatis, M. kansasii, M. avium) in a modified Microplate Alamar Blue Assay. We identified several candidate molecules with micromolar MIC against M. tuberculosis H37Ra and low in vitro cytotoxicity in HepG2 cell line, for example, N-(4-hydroxyphenyl)-5-(pentylamino)pyrazine-2-carboxamide (3c, MIC = 3.91 mu g/mL or 13.02 mu M, SI > 38) and 5-(heptylamino)-N-(p-tolyl)pyrazine-2-carboxamide (4e, MIC = 0.78 mu g/mL or 2.39 mu M, SI > 20). In a complementary screening, we evaluated the in vitro activity against bacterial and fungal strains of clinical importance. We observed no antibacterial activity and sporadic antifungal activity against the Candida genus.

Lithium Functionalization Promoted by Amide-Containing Ligands of a Cu(pzdc)(pia) Porous Coordination Polymer for CO2 Adsorption Enhancement

A pillared layer network containing amide functional groups (Cu(pzdc)(pia); pzdc = pyrazine-2,3-dicarboxylate; pia = N-(4-pyridyl)isonicotinamide) was used to test a postsynthesis metalation rationale to insert lithium and create a porous surface with enhanced CO2 adsorption capacity. Synchrotron powder X-ray diffraction (XRD) was used to determine variations after lithiation in long-range and textural properties. CO2 adsorption measurements at room temperature showed a concave up isotherm shape with an increasing adsorption at high pressures, surpassing by 1 order of magnitude the values previously reported for the unmodified material. There was significant hysteresis upon desorption, which suggests structural variations consequent to different or stronger adsorption sites. Results from elemental, thermal gravimetric, and crystal refinement analyses indicate that the lithium content is ca. 3 Li atoms per asymmetric unit. Raman scattering showed N-Li and Li-O stretching bands, a shift of pia amide- and pyridyl-related bands, and other significant skeletal vibrations associated with nitrogen and oxygen lone pair variations. In situ XRD and CO2 adsorption observations at up to 50 bar at ambient temperature were consistent with the anticipated structural dynamic variation. The lattice changes observed at pressures below 10 bar following lithiation may be directly related to an enhancement in the CO2 adsorption amount.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 19847-12-2, in my other articles.

Synthesis, molecular docking studies, and in vitro antimicrobial evaluation of piperazine and triazolo-pyrazine derivatives

For this work, two series of new piperazine derivatives (3a-o) and triazolo-pyrazine derivatives (3p-t) were synthesized in a single-step reaction. All twenty adducts were obtained in good to high yields and fully characterized by H-1 NMR, C-13 NMR, IR, and mass spectrometry techniques. To further confirm the chemical identity of the adducts, a crystal of N-{[(4-chlorophenyl)-3-(trifluoromethyl)]-5,6-dihydro-[1,2,4]triazolo[4,3-a]}pyrazine-7(8H)-carboxamide (3t) was prepared and analyzed using X-ray crystallography. In vitro screening of the antimicrobial activity of all compounds (3a-t) was evaluated against five bacterial and two fungal strains. This study disclosed that N-{[(3-chlorophenyl)]-4-(dibenzo[b,f][1,4]thiazepin-11-yl)}piperazine-1-carboxamide (3o) was the superior antimicrobial with good growth inhibition against A. baumannii. Furthermore, the results from the performed molecular docking studies were promising, since the observed data could be used to develop more potent antimicrobials.

Staphylococcus xylosus VITURAJ10: Pyrrolo [1,2 alpha] pyrazine-1,4-dione, hexahydro-3-(2-methylpropyl) (PPDHMP) producing, potential probiotic strain with antibacterial and anticancer activity

In the present study bacterial strain (VITURAJ10), isolated from goat milk was characterised for its probiotic potential. The various probiotic traits included tolerance to acidic pH (up to pH 3), bile salts (0.3%) and transit gut environment (simulated with digestive juices such as pepsin, Oxgall and pancreatin). The isolate could withstand high NaCl concentrations in the growth medium, showed inability to produce hemolysin and did not hydrolyse mucin. VITURAJ10 was capable of forming biofilm and produced exopolysachharide. The bioactive metabolites produced by the isolate were extracted and they showed growth suppressing activity towards pathogenic strains such as Escherichia coli, Salmonella enterica and Staphylococcus aureus. The crude extract was fractionated with solid phase extraction (SPE) chromatography and the fractions 10 and 12 were found to be effective against the bacterial pathogens. The fractions were further gauged for cytotoxic activity against MCF-7 cell line by MIT assay. The biologically significant compounds identified through GC-MS and FT-IR analysis in the fractions were, Actinomycin D, Pyrrolo [1,2 alpha] Pyrazine-1,4-Dione, Hexahydro 3 (2 Methylpropyl)(PPDHMP) and Didemnin B. The phylogenetic taxonomy of the isolate revealed the isolate to be the closest neighbour of Staphylococcus xylosus VITURAJ10 (GenBank accession no.KX770743.1 ) as per the16S rRNA gene sequencing and subsequent phylogenetic tree analysis.
