Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Journal of Molecular Structure called Mononuclear and binuclear dioxidomolybdenum(VI) complexes of ONO appended aroylhydrazone: Crystal structures, interaction energy calculation and cytotoxicity, Author is Kuriakose, Daly; Kurup, M. R. Prathapachandra, which mentions a compound: 3326-71-4, SMILESS is O=C(C1=CC=CO1)NN, Molecular C5H6N2O2, Computed Properties of C5H6N2O2.

Mono- and binuclear cis-MoO2 complexes (1-3) [MoO2(ISF)D] (D = H2O 1, DMSO 2 and 4,4′-bipyridine 3; ISF = 3,5-diiodosalicyaldehyde-2-furoichydrazone) were synthesized and fully characterized by different physicochem. methods. The mol. structures were confirmed unambiguously by single crystal x-ray diffraction studies. The octahedral geometry around the Mo(VI) central atom is satisfied by O, N, O donor atoms of dideprotonated dianionic hydrazone moiety, two oxido oxygens and O/N atoms of the coordinated solvent mols. The asym. unit of complexes 1 and 2 contains one mol. whereas complex 3 contains only half of the mol. The 4,4′-bipyridine mol. acts as a linker that links the two asym. MoO2D moieties to form the binuclear dioxidomolybdenum(VI) in complex 3 with Mo···Mo nonbonding distance of 12.01(10) Å. The relevance of H bonding and nonbonding interactions in the construction of supramol. architectures were studied. The upshots of single crystal studies were reproduced with the aid Hirshfeld surface studies. The pre-eminence of dispersion energy component over other components was established by interaction energy calculations and the energy framework anal. The average interaction energy values for complexes 2 and 3 are -282.3 and -228.3 kJ mol-1, resp. Also the in vitro cytotoxicity of all the synthesized compounds was evaluated against lymphoma ascites cell line.

In this study, a novel hydrazide-based compound, (E)-N′-(5-(benzo[d]thiazol-2-yl)-2-hydroxybenzylidene)furan-2-carbohydrazide (probe BOTH, I) was designed, characterized and prepared as a fluorogenic “”turn-on”” sensor for monitoring Al3+ in near-perfect aqueous media. All emission and absorbance spectral studies were performed in HEPES/DMSO (volume/volume, 99.95/0.05, pH = 7.0) media at 25 °C. The quantum yield of probe BOTH increases considerably in the presence of Al3+. Probe BOTH could sense Al3+ at a concentration as low as 6.47 nM. Probe BOTH could sense Al3+ with high sensitivity and selectivity, and a quant. correlation of R2 = 0.9887 in the Al3+ concentration range of 0.0-20.0 equivalent To evaluate the method parameters, a validation study was performed based on different anal. parameters. The formation of complex BOTH-Al3+ (2 : 1 stoichiometry) was confirmed by 1H-NMR titration and MALDI-TOF MS, as well as Job′s methods. pH-Dependent and Benesi-Hildebrand plot studies also supported this proposed sensing mechanism. Besides, the binding mechanism of Al3+ with probe BOTH was further verified by theor. studies. Moreover, probe BOTH could be used for monitoring Al3+ in living-cells and water samples.

Succinate dehydrogenase (SDH) present in the inner mitochondrial membrane is an important target enzyme for the design of SDH inhibitor-type fungicides. Using SDH as the target enzyme, 22 novel longifolene-derived diacylhydrazine compounds were designed and synthesized using the renewable natural product longifolene as the starting material. Their structures were confirmed by IR, 1H NMR, 13C NMR, electrospray mass spectrometry, and elemental anal. In vitro antifungal activity of the target compounds was preliminarily evaluated. As a result, some of them showed better or comparable antifungal activity than that of the com. fungicide chlorothalonil, in which compound I had inhibitory rates of 97.5, 80.5, 72.1, and 67.1% against Physalospora piricola, Colletotrichum orbiculare, Alternaria solani, and Gibberella zeae, resp., presenting excellent and broad-spectrum activity that deserved further study. Besides, a reasonable and effective three-dimensional structure-activity quant. relationship model has been established. There was a significant pos. correlation between the antifungal activity and the docking-based binding energy analyzed using Spearman’s rank correlation algorithm. Also, the simulative binding pattern of the target compounds with SDH was investigated by mol. docking study. Furthermore, the diacylhydrazine and phenol groups of the target compounds were proposed to be the potential pharmacophores by frontier MO anal.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system.

The borrowing hydrogen strategy has been applied in the synthesis of nonsym. N,N-dialkylated acyl hydrazides via a tandem three-component reaction catalyzed by a phosphine free diaminocyclopentadienone ruthenium tricarbonyl complex.

Different aromatic acyl hydrazides underwent dialkylation with a variety of primary or secondary alcs. and methanol or ethanol as alkylating agents in mild reaction conditions and good yields.

Author is Aydin, Duygu.

Early detection of probes is very important for limiting toxic effects of various transition metal ions for example aluminum and zinc. Monitoring of these metal ions can be challenging via conventional methods since they are high cost instrumentations, time consuming and so on. The authors report facile preparation of a fluorescence probe containing biphenyl groups that effectively selective and superb sensitivity towards aluminum(III) and zinc(II) in neutral solutions without interference from each other and other ions. In neutral pH value, the probe FOB displayed the OFF-ON fluorescence enhancement at 464 nm and 512 nm toward aluminum(III) and zinc(II), resp. The detection limit values of FOB for Al3+ and Zn2+ in neutral solutions were 1.27 and 1.02 nM, resp. and these values were significantly lower than permitted Al3+ and Zn2+ concentrations in drinking water determined by the World Health Organization (WHO) and European Water Quality. Also, fabricated cyano-biphenyl based probe is effective for sensing for aluminum(III) and zinc(II) in living human colon cancer cells even when employed at low concentrations (1.0μM). Overall, this work allows the authors to obtain a great potential to be applied to detect Al3+ and Zn2+.
