Now introduce a scientific discovery about this category.

The title compound, C18H20O4, is structurally similar to podophyllotoxin. It contains a fused dioxole and phenyl ring system and an unfused phenyl ring which are almost perpendicular to each other. However, this compound lacks the cyclohexyl and lactone rings which are present in podophyllotoxin. In addition, the unfused phenyl ring in podophyllotoxin contains three methoxy groups in the para and meta positions, whereas the title compound contains only an ethoxy group in the para position.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 91526-18-0 is helpful to your research. Quality Control of 4-(Hydroxymethyl)-5-methyl-1,3-dioxol-2-one.

We describe for the first time the free radical cyclization of enantiomerically pure alkyne-tethered aldehydes obtained from a carbohydrate (6, 7). The synthesis of compounds 6 and 7 obtained from a derivative of D-ribose is reported. These radical precursors have been submitted to cyclization with tributyltin hydride plus azobisisobutyronitrile to yield, after ring closure, two carbocycles, respectively. These carbocycles have been obtained as mixtures of E and Z vinyltin isomers, but with excellent diastereoselection at the new stereocenter formed during the ring closure. After protodestannylation, only one diastereomer was detected and isolated. The absolute configuration at the new stereocenter formed during the carbocyclization has been established by detailed H-1 NMR analysis. The specific transformation of 7-methoxymethoxy-2,2-dimethyl-4-methylene-5-tertbutyldimethylsilyloxy-(3aR,5S,7S,7aS)-perhydrobenzo[d][1,3]dioxole into optically pure (+)-allo-quercitol and (+)-talo-quercitol is described. From these results, we conclude that under an appropriate choice of radical precursors and conditions, the synthesis of highly functionalized cyclohexane derivatives of biological interest is now available.

DNA adducts represent internal dosimeters to measure exposure to environmental and endogenous genotoxicants. Unfortunately, in molecular epidemiologic studies, measurements of DNA adducts often are precluded by the unavailability of fresh tissue. In contrast, formalin-fixed paraffin embedded (FFPE) tissues frequently are accessible for biomarker discovery. We report here that DNA adducts of aristolochic acids (AAs) can be measured in FFPE tissues at a level of sensitivity comparable to freshly frozen tissue. AAs are nephrotoxic and carcinogenic compounds found in Aristolochia herbaceous plants, many of which have been used worldwide for medicinal purposes. AAs are implicated in the etiology of aristolochic acid nephropathy and upper urinary tract carcinoma. 8-Methoxy-6-nitrophenanthro-[3,4-d]-1,3-dioxole-5-carboxylic acid (AA-I) is a component of Aristolochia herbs and a potent human urothelial carcinogen. AA-I reacts with DNA to form the aristolactam (AL-I)-DNA adduct 7-(deoxyadenosin-N-6-yl) aristolactam I (dA-AL-I). We established a method to quantitatively retrieve dA-AL-I from FFPE tissue. Adducts were measured, using ultraperfonnance liquid chromatography/mass spectrometry, in liver and kidney tissues of mice exposed to AA-I, at doses ranging from 0.001 to 1 mg/kg body weight. dA-AL-I was then measured in 10-mu m thick tissue-sections of FFPE kidney from patients with upper urinary tract cancers; the values were comparable to those observed in fresh frozen samples. The limit of quantification of dA-AL-I was 3 adducts per 109 DNA bases per 2.5 mu g of DNA. The ability to retrospectively analyze FFPE tissues for DNA adducts may provide clues to the origin of human cancers for which an environmental cause is suspected.

A divergent synthesis of 10 icetexane natural products based on a proposed biogenetic cationic ring expansion of a reduced carnosic acid derivative is described. Of these icetexanes, (+)-salvicanol, (-)-cyclocoulterone, (-)-coulterone, (-)-obtusinone D, and (-)-obtusinone E have been synthesized for the first time. In addition, the hypothesis for the non-enzymatic biogenesis of benzo[1,3]dioxole natural products has been experimentally investigated. Additional experimental evidence for the abiotic formation of the methylenedioxy unit is provided, as photolysis of the quinone (+)-komaroviquinone resulted in the formation of the [1,3]dioxole-containing natural product (-)-cyclocoulterone and (+)-komarovispirone.

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.

The enantiomers of spiro[benzo-1,3-dioxole-2,9′-bicyclo[3.3.1]nonan]-2′-one 2 and the corresponding diastereomeric exo-2′- and endo-2′-hydroxy acetals 3a,b obtained from this monoacetal were solved by HPLC on a swollen microcrystalline triacetylcellulose column. The absolute configuration of the enantiomers of 2 and 3a,b was assigned based on the signs of the Cotton effect and employing the octant rules for the carbonyl and the aromatic chromophores The low intensity of the band at 290 nm in the CD spectrum of monoacetal 2 was accounted far by the interaction of the carbonyl and aromatic chromophores.

Black pepper (Piper nigrum) contains a variety of alkamides. Among them, piperine has been reported to have antidepressant-like effects in chronically stressed mice, but little is known about the biological activity of other alkamides. In this study, we investigated the effects of alkamides from white pepper (P. nigrum) on neuronal cells. Twelve alkamides were isolated from white pepper MeOH extracts, and their chemical structures were identified by NMR and MS analyses. The compounds were subjected to assays using the luciferase-reporter gene under the control of the BDNF promoter or cAMP response element in mouse neuroblastoma Neuro-2a cells. In both assays, marked reporter-inducing activity was observed for piperine (1), piperettine (2) and piperylin (7), all of which have in common an (E)-5-(buta-1,3-dien-1-yl)benzo[d] [1, 3] dioxole moiety. Piperettine (2) and piperylin (7) tended to increase endogenous BDNF protein levels. Furthermore, piperylin (7) promoted retinoic acid-induced neurite outgrowth. These results suggest that piperylin (7), or analogues thereof, may have a beneficial effect on disorders associated with dysregulation of BDNF expression, such as depression.

Four amphetamine derivatives bearing a methylenedioxy group at positions 3 and 4 of the benzene ring and differing in their substitution at C(6) were studied by differential pulse voltammetry in aqueous media. These experiments showed a single oxidation peak for the C(6)-H, -Br and -Cl compounds, while the C(6)-NO2 analogue was not oxidized. The oxidation peak is interpreted as due to the removal of one electron from the aromatic electrophore with formation of a radical cation stabilized by the dioxole ring. The linear relationship between the peak current and the concentration of the derivatives is appropriate for development of a quantitative method for their determination. pK’ values were determined using both electrochemical and spectrophotometric methods.
