Having gained chemical understanding at molecular level, chemistry graduates may choose to apply this knowledge in almost unlimited ways, as it can be used to analyze all matter and therefore our entire environment. 87-72-9, Name is L-Arabinopyranose, SMILES is OC1[C@H](O)[C@@H](O)[C@@H](O)CO1, belongs to dioxole compound. In a document, author is Stiborova, Marie, introduce the new discover, Category: dioxoles.

Exposure to the plant nephrotoxin and carcinogen aristolochic acid (AA) leads to the development of AA nephropathy, Balkan endemic nephropathy (BEN) and upper urothelial carcinoma (UUC) in humans. Beside AA, exposure to ochratoxin A (OTA) was linked to BEN. Although OTA was rejected as a factor for BEN/UUC, there is still no information whether the development of AA-induced BEN/UUC is influenced by OTA exposure. Therefore, we studied the influence of OTA on the genotoxicity of AA (AA-DNA adduct formation) in vivo. AA-DNA adducts were formed in liver and kidney of rats treated with AA or AA combined with OTA, but no OTA-related DNA adducts were detectable in rats treated with OTA alone or OTA combined with AA. Compared to rats treated with AA alone, AA-DNA adduct levels were 5.4- and 1.6-fold higher in liver and kidney, respectively, of rats treated with AA combined with OTA. Although AA and OTA induced NAD(P)H:quinone oxidoreductase (NQO1) activating AA to DNA adducts, their combined treatment did not lead to either higher NQO1 enzyme activity or higher AA-DNA adduct levels in ex vivo incubations. Oxidation of AA I (8-methoxy-6-nitrophenanthro[3,4-d]-1,3-dioxole-5-carboxylic acid) to its detoxification metabolite, 8-hydroxyaristolochic acid, was lower in microsomes from rats treated with AA and OTA, and this was paralleled by lower activities of cytochromes P450 1A1/2 and/or 2C11 in these microsomes. Our results indicate that a decrease in AA detoxification after combined exposure to AA and OTA leads to an increase in AA-DNA adduct formation in liver and kidney of rats.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 87-72-9. Category: dioxoles.

Now introduce a scientific discovery about this category.

The supramolecular solid state structure of Na+, K+, Ca2+ and NH4+ salts of difluoro((2,2,4,5-tetrafluoro-5-(trifluoromethoxy)-1.3-dioxolan-4-yl)oxy)acetic acid have been investigated by means of IR and Raman vibrational spectroscopy, and Density Functional Theory (DFT) calculations on suitable molecular models. In the case of NH4+ salts, additional insights have been provided by X-Ray diffraction measurements on crystalline powders. Based on the analysis of IR and Raman spectra, the structure of the different salts at the molecular level is identified. In NH4+ salts, the spectra indicate the existence of different stable complexes, while for the other salts only one type of aggregation is observed. For NH4+ salts, it has been analyzed the effect of solvation in water, focusing on the specific features shown by the IR spectrum: this gave a further insight on the peculiar aggregation properties observed. For all the cases-studied, DFT calculations gave a satisfactory interpretation of the experimental vibrational spectra based on the structure of different models of molecular complexes, and allowed the identification of characteristic marker bands related to different supra-molecular architectures.

Perfluoro(5-methylene-2,2-dimethyl-1,3-dioxolane) (1) was synthesized by utilizing a direct fluorination reaction. Compound 1 was an entirely novel monomer with difluoromethylene at position 5 on the dioxolane ring as an unprecedented polymerization site. It successfully polymerized with tetrafluoroethylene to afford copolymers, which had T-g values in the range of 60-90 degrees C. The content of monomer 1 in the obtained polymers was less than 20 mol%, which seemed insufficient for giving various unique properties to polymers. However, each polymer was expected to be a superior material because of their advanced thermal stability. Comparison with copolymers of 2,2-bis(trifluoromethyl)-4,5-difluoro-1,3-dioxole and tetrafluoroethylene is also discussed. (C) 2007 Elsevier B.V. All rights reserved.

Molecular behavior of the building block ([2-(1,3-dithiole-2-ylidene)-1,3-dithiole] =tetrathiafulvalene (TTF)} of organic superconductors have been investigated along with its three derivatives, namely, {[2-(1,3-dioxole-2-ylidene)-1,3-dioxole] tetraoxafulvalene (TOF)}; [2,2]-bi-[[1,3] oxathiolylidene]=Der I and 2-(3H-Furan-2-ylidene)-[1,3] oxathiole=Der II. The properties of the molecules such as molecular geometries, frontier MOs and vibrational spectra have been investigated by using DFT method at the B3LYP level employing 6-311++G(d,p) basis set. The geometrical parameters and atomic charges on various atomic sites of the TTF, TOF, Ders land II suggest extended conjugation in these systems. The present calculations lead to the reassignments for of some of the fundamentals and new interpretations for some of the observed IR and Raman frequencies. One of the two modes involved in the Fermi resonance giving rise to the doublet 1555 and 1564 cm(-1) needed to be revised and another doublet 3083 and 3108 cm(-1) could be interpreted as a Fermi resonance doublet. Out of the two nu(C=C) modes under the a(1) species, the lower frequency mode is assigned to the nu(C=C) of the ring and the higher one to the nu(C=C) of the central C=C bond contrary to the assignment reported in literature. The conducting properties of these molecules depend mainly on this mode. (C) 2012 Elsevier B.V. All rights reserved.

BACKGROUND: Numerous works have been published on the chemical modification of chitosan; this polymer is still being modified, leading to various derivatives with improved properties. In the present study, heterocyclic aldehydes including furan-2-carbaldehyde, 5-methylfuran-2-carbaldehyde, 3-pyridine carboxyaldehyde, benzo[d][1,3]dioxole-5-carbaldehyde and 4-oxo-4H-chromene-3-carbaldehyde were reacted with chitosan by a reductive alkylation reaction to produce for the first time five new N-heterocyclic chitosan derivatives to improve the biological activity of chitosan against the most important economic plant pests including fungi and insects, in particular the cotton leafworm Spodoptera littoralis. RESULTS: The chemical structures of the synthesized compounds were confirmed by H-1 NMR spectroscopy and the degree of substitution ranged from 0.30 to 0.43. The fungicidal assessment was investigated in vitro using a mycelia radial growth inhibition technique against soil-borne pathogenic fungi Fusarium oxysporum and Pythium debaryanum and the rice leaf blast Pyricularia grisea. The results showed that N-[(5-methylfuran-2-yl)methyl] chitosan was the most active against P. grisea with an EC50 value of 0.919mg mL(-1) while N-(benzo[d][1,3]dioxol5-ylmethyl) chitosan and N-(methyl-4H-chromen-4-one) chitosan exhibited the most potent fungicidal activity against P. debaryanum and F. oxysporum. An insecticidal bioassay against the larvae of S. littoralis showed that N-(methyl-4H-chromen-4-one) chitosan exhibited a significant growth inhibition and antifeedant activity among the synthesized compounds. CONCLUSION: The chemical modification of chitosan molecule with a heterocyclic moiety led to an enhancement in the biological activity against the plant pathogenic fungi F. oxysporum, P. debaryanum and P. grisea and the cotton leafworm insect S. littoralis.
