The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research. 526-95-4, Name is Gluconic Acid (contains Gluconolactone), SMILES is O[C@H]([C@H]([C@@H]([C@@H](CO)O)O)O)C(O)=O, in an article , author is Li, Wanfang, once mentioned of 526-95-4, Electric Literature of 526-95-4.

A series of 3-oxoglutaric acid derivatives have been hydrogenated in different solvents in the presence of [RuCl(benzene)(S)-SunPhos]Cl (SunPhos=(2,2,2′,2′-tetramethyl-[4,4′-bibenzo[d][1,3]dioxole]-5,5′-diyl)bis(diphenylphosphine)). Unlike simple beta-keto acid derivatives, these advanced analogues can be readily hydrogenated in uncommon solvents such as THF, CH2Cl2, acetone, and dioxane with high enantioselectivities. Two possible catalytic cycles have been proposed to explain the different reactivities of these 1,3,5-tricarbonyl substrates in the tested solvents. The C-2 and C-4 substituents had notable but irregular influence on the reactivity and enantioselectivity of the reactions. More pronounced solvent effects were observed: the ee values increased from around 20?% in EtOH or THF to 90?% in acetone. Inversion of the product configuration was observed when the solvent was changed from EtOH to THF or acetone, and a mixed solvent system can lead to better enantioselectivity than a single solvent.

Photooxygenation of the cycloheptatriene derivative 9 gave the bicyclic endoperoxide 14. Cleavage of the peroxide linkage in 14 with thiourea resulted in the formation of 16. Treatment of the endoperoxide 14 with a catalytic amount of triethylamine provided a new isomer of stipitatic acid 11, and 16. Pyrolysis or the CoTPP (TPP = tetraphenylporphyrin) catalyzed reaction of 14 resulted in the formation of iso-stipitatic acid 10, and 18,

The trimolecular condensation of indole, Meldrum’s acid and chiral, sugar-derived aldehydes took place in good yield and high diastereoselectivity. The absolute configuration of the alpha-carbon of the chiral aldehydes ensured a predictable diastereocontrol of the newly created stereogenic centre except for (3aR,5S,6S,6aR)-6-benzyloxy-2,2-dimethyl-tetrahydrofuro[3,2-d][1,3]dioxole-5-carbaldehyde 3i. In this case, the opposite stereochemistry may be explained by a less congested conformer of the Knoevenagel-adduct intermediate. (C) 2010 Elsevier Ltd. All rights reserved.

The solubilities of N-2, CO2, CH4, C2H6, C3H8, and C3F8 and permeabilities of N-2, O-2, CO2, CH4, C2H6, and C3H8 were determined in a glassy, amorphous fluoropolymer prepared from 80 mol % 2,2,4-trifluoro-5-trifluoromethoxy-1,3-dioxole (TTD) and 20 mol % tetrafluoroethylene (TFE), commercially known as Hyflon AD 80. This polymer exhibits lower increases in hydrocarbon gas and vapor solubility with increasing penetrant critical temperature than conventional hydrocarbon polymers. On the basis of a best fit of the natural logarithm of solubility vs critical temperature, Hyflon AD 80 should have much lower solubility for high molar mass hydrocarbon compounds (e.g., n-decane) than conventional hydrocarbon polymers. Pure gas CO2/CH4 separation properties of this polymer are comparable with those of some hydrocarbon polymers considered for natural gas purification. When exposed to a feed stream containing a mixture of CO2 and CH4, the polymer exhibits a CO2 permeability of approximately 250 barrers and a CO2/CH4 mixed-gas selectivity of 10.6 at 1.6 atm CO2 partial pressure. The mixed gas selectivity decreases minimally as CO2 partial pressure increases to 10.6 atm. The mixed gas selectivity is also maintained when moderate amounts of toluene and n-hexane are present in the CO2-CH4 feed stream. Diffusion coefficients, calculated from pure gas permeability and solubility coefficients, suggest membrane plasticization at higher pressures of CO2 and C2H6. The polymer also exhibits reversible hysteresis in C3H8 permeability with pressure.

Four chemicals (Dioxole 418, Dioxolane 418, Dioxolane 416 and Dioxolane 456) which are used as stabilizers in highresolution image were tested or both their acute and repeated inhalation toxicity in the rat using nose-only exposures. Acute studies determined the lethal concentrations following a single 4-hour exposure, repeated exposure inhalation studies determined the potency and target tissue(s) following 6-hour/day exposures, 5 days/week for 2 weeks. Each of the chemicals was at least mildly toxic acutely with approximate lethal concentrations of > 1,500 ppm for Dioxole 418, 1,300 ppm for Dioxolane 418, 1,700 ppm for Dioxolane 416, and 4,300 ppm for Dioxolane 456. No specific unusual clinical signs of response were seen in the rats exposed acutely. Repeated exposures with Dioxole 418 and Dioxolane 418 resulted in no evidence of toxicity with NOAEL’s being 440 and 500 ppm respectively (the highest concentrations tested). Repeated exposures to 250 ppm Dioxolane 456 were not tolerated with mortalities observed after exposure. Severe bone marrow hypoplasia along with reductions in platelet and neutrophil counts were observed at this concentration with less severe hemopoietic changes seen also at 10 and 51 ppm. The no-effect level for Dioxolane 456 was determined to be 10 ppm in female rats and I ppm in males. The same hemopoietic effects were seen with Dioxolane 416 at exposures of 53 ppm or greater in males but not in females exposed to 53 ppm Dioxolane 416. Hepatocellular hypertrophy and depression of serum alkaline phosphatase activity were seen in male rats exposed to 500 but not 53 ppm Dioxolane 416. Testicular degeneration was also seen in rats exposed to 500 ppm Dioxolane 416. The NOAEL was 5 ppm for the chemical.

Safety of Gluconic Acid (contains Gluconolactone)526-95-4, Name is Gluconic Acid (contains Gluconolactone), SMILES is O[C@H]([C@H]([C@@H]([C@@H](CO)O)O)O)C(O)=O, belongs to dioxole compound.

Human Carboxylesterase 2A (hCES2A), one of the most important serine hydrolases, plays crucial roles in the hydrolysis and the metabolic activation of a wide range of esters and amides. Increasing evidence has indicated that potent inhibition on intestinal hCES2A may reduce the excessive accumulation of SN-38 (the hydrolytic metabolite of irinotecan with potent cytotoxicity) in the intestinal tract and thereby alleviate the intestinal toxicity triggered by irinotecan. In this study, more than sixty natural alkaloids have been collected and their inhibitory effects against hCES2A are assayed using a fluorescence-based biochemical assay. Following preliminary screening, seventeen alkaloids are found with strong to moderate hCES2A inhibition activity. Primary structure-activity relationships (SAR) analysis of natural isoquinoline alkaloids reveal that the benzo-1,3-dioxole group and the aromatic pyridine structure are beneficial for hCES2A inhibition. Further investigations demonstrate that a steroidal alkaloid reserpine exhibits strong hCES2A inhibition activity (IC50 = 0.94 mu M) and high selectivity over other human serine hydrolases including hCES1A, dipeptidyl peptidase IV (DPP-IV), butyrylcholinesterase (BChE) and thrombin. Inhibition kinetic analyses demonstrated that reserpine acts as a noncompetitive inhibitor against hCES2A-mediated FD hydrolysis. Molecular docking simulations demonstrated that the potent inhibition of hCES2A by reserpine could partially be attributed to its strong sigma-pi and S-pi interactions between reserpine and hCES2A. Collectively, our findings suggest that reserpine is a potent and highly selective inhibitor of hCES2A, which can be served as a promising lead compound for the development of more efficacious and selective alkaloids-type hCES2A inhibitors for biomedical applications.

The five-membered 1,3-dioxolane ring adopts an envelope form, with the C atom bonded to the olefin side chain as the flap, which deviates from the mean plane through the other four atoms by 0.564 (7) angstrom. The 1,3-dioxole ring fused to the benzene ring adopts a flattened envelope form, with the C atom between the two O atoms as the flap, which deviates from the mean plane through the other four atoms by 0.215 (7) angstrom. The C-C=C-C olefin moiety is essentially planar and makes a dihedral angle of 87.1 (3)degrees with the benzene ring. An intramolecular O-H center dot center dot center dot O hydrogen bond supports the molecular conformation, enclosing an S(11) graph-set motif.

Carbonyl ylides arising from ethyl acetodiazoacetate/dimethyl diazomalonate and a,beta-enones with mainly s-cis conformations underwent disrotatory cyclization to produce dihydrofuran derivatives. This process proved to be sensitive to steric effects. The corresponding ylides arising from rather s-trans a,beta-enals yielded dioxole derivatives. The mechanisms of the reactions are discussed.
