Brockway, Anthony J. published the artcileSynthesis and evaluation of analogs of 5′-(((Z)-4-amino-2-butenyl)methylamino)-5′-deoxyadenosine (MDL 73811, or AbeAdo) – An inhibitor of S-adenosylmethionine decarboxylase with antitrypanosomal activity, COA of Formula: C8H14O2, the publication is Bioorganic & Medicinal Chemistry (2017), 25(20), 5433-5440, database is CAplus and MEDLINE.

We describe our efforts to improve the pharmacokinetic properties of a mechanism-based suicide inhibitor of the polyamine biosynthetic enzyme S-adenosylmethionine decarboxylase (AdoMetDC), essential for the survival of the eukaryotic parasite Trypanosoma brucei responsible for Human African Trypanosomiasis (HAT). The lead compound, 5′-(((Z)-4-amino-2-butenyl)methylamino)-5′-deoxyadenosine (1, also known as MDL 73811, or AbeAdo), has curative efficacy at a low dosage in a hemolymphatic model of HAT but displayed no demonstrable effect in a mouse model of the CNS stage of HAT due to poor blood-brain barrier permeation. Therefore, we prepared and evaluated an extensive set of analogs with modifications in the aminobutenyl side chain, the 5′-amine, the ribose, and the purine fragments. Although we gained valuable structure-activity insights from this comprehensive dataset, we did not gain traction on improving the prospects for CNS penetration while retaining the potent antiparasitic activity and metabolic stability of the lead compound 1.

Varfolomeev, S. D. published the artcileNew possibilities in the synthesis of fuel oxygenates from renewable sources, Synthetic Route of 177-10-6, the publication is Russian Chemical Bulletin (2019), 68(4), 717-724, database is CAplus.

A general problem in the production of the main types of liquid biofuel, bioethanol and biodiesel, is that renewable resources are not utilized completely. These are ballast polyols: hemicellulose or its structural units, pentaat. monosaccharides (xylose and arabinose), and biodiesel glycerol. The problem of utilization of these compounds by transforming them into a hydrophobized fuel form by the conversion to cyclic ketals (CK) during condensation with lower carbonyl compounds is reviewed. The CK-ethanol pair significantly increases the octane number and provides phase stability of fuel compositions The ability of CK to inhibit radical processes responsible for fuel characteristics was studied in model reactions with Ph radicals and at. chlorine. The carbon-centered radicals formed in protic media are transformed into more stable cyclic radical cations. Alternative methods of processing natural raw materials using biocatalysis and supercritical fluid technologies are analyzed.

Cyclic ketals and acetals (1,3-dioxolanes) substituted at positions 2 and 4 of the dioxolane ring, prepared by condensation of glycerol and ethylene glycol with aldehydes and ketones, exhibited antimicrobial activity against Gram-pos. and Gram-neg. bacteria. This activity, which may be associated with the antiradical activity of the compounds and depended on their hydrophilic-hydrophobic balance, allows targeted variation in structural parameters for the creation of new active compounds Cyclic ketals with high antimicrobial activity can be used as antiseptics for sterilization of working surfaces and instruments.

Kujala, Tytti S. published the artcileBetalain and phenolic compositions of four beetroot (Beta vulgaris) cultivars, Related Products of dioxole, the publication is European Food Research and Technology (2002), 214(6), 505-510, database is CAplus.

Four cultivars of red beetroot (Beta vulgaris) were evaluated with respect to their betalain and phenolic contents. The compounds were analyzed using HPLC and identified by HPLC-DAD, HPLC-ESI-MS and NMR techniques. Betalains (vulgaxanthins I and II, betanin and isobetanin) and phenolics [5,5′,6,6′-tetrahydroxy-3,3′-biindolyl, feruloylglucose and β-D-fructofuranosyl-α-D-(6-O-(E)-feruloylglucopyranoside)] were determined in different parts of the root; betalains were analyzed sep. in the water extract and phenolics in the fractionated 80% aqueous methanol extract (betalain-free water fraction). In each cultivar, both betanin and isobetanin were found in greater amounts in the peel than in the flesh. A similar trend was not observed in the distribution of vulgaxanthins. The three studied phenolics appeared in all root parts of the beetroot cultivars with the flesh generally containing the least content. Addnl., two phenolic amides (N-trans-feruloyltyramine and N-trans-feruloylhomovanillylamine) and four flavonoids (betagarin, betavulgarin, cochliophilin A and dihydroisorhamnetin) were detected in the fractionated 80% aqueous methanol peel extracts (acetonitrile fraction) of beetroot.

A novel family of lamellar MOF-type materials, which contain Bronsted acid sites together with redox active centers, based on assembled 1D organic-inorganic nanoribbons were obtained through direct solvothermal synthesis routes, using specific monotopic benzylcarboxylate spacers with thiol substituents in the para-position like structural modulator compounds and effective post-synthesis oxidized treatments to generate accessible sulfonic groups. Low-dimensional aluminum metal-organic materials, containing free sulfonic pendant groups (Al-ITQ-SO₃H), were successfully tested in several acid reactions, such as acetalization, esterification and ring opening of epoxides with a significant impact on fine chem. processes. The direct introduction of stabilized Pd nanoparticles, cohabitating with pendant sulfonic groups, allowed the preparation of active bi-functional MOF-type hybrid materials (Al-ITQ-SO₃H/Pd) capable of carrying out one-pot two-step oxidation-acetalization reactions, exhibiting high yield and high activity during consecutive catalytic cycles.

The coupling reaction of oxiranes with carbonyl compounds to produce 1,3-dioxolanes was promoted by catalytic amounts of a bentonitic clay. The product yield was found to be dependent on the catalyst, the reaction temperature and the reagent concentrations Thus, ethylene oxide (I) reacted with MeCOMe in the presence of the clay to give 2,2-dimethyl-1,3-dioxolane in 96% yield. Reacting I with MeCO(CH₂)₂Me gave 2-methyl-2-propyl-1,3-dioxolane in 25% yield. A kinetic study performed with acetone and ethylene oxide showed a first-order dependence in both reagents. Other experiments made with different epoxides, carbonyl compounds and catalysts are also discussed.

Gayubo, A. G. published the artcilePyrolytic lignin removal for the valorization of biomass pyrolysis crude bio-oil by catalytic transformation, Computed Properties of 1193-11-9, the publication is Journal of Chemical Technology and Biotechnology (2010), 85(1), 132-144, database is CAplus.

BACKGROUND: The catalytic processes for valorizing the bio-oil obtained from lignocellulosic biomass pyrolysis face the problem that a great amount of carbonaceous material is deposited on the catalyst due to the polymerization of phenol-derived compounds in the crude bio-oil. This carbonaceous material blocks the catalytic bed and contributes to rapid catalyst deactivation. This paper studies an online two-step process, in which the first one separates the polymerizable material and produces a reproducible material whose valorization is of com. interest. RESULTS: The establishment of a step for pyrolytic lignin deposition at 400 °C avoids the blockage of the online catalytic bed and attenuates the deactivation of a HZSM-5 zeolite based catalyst used for hydrocarbon production The origin of catalyst deactivation is coke deposition, which has two fractions (thermal and catalytic), whose content is attenuated by prior pyrolytic lignin separation and by co-feeding methanol. The morphol. and properties of the material deposited in the first step (pyrolytic lignin) are similar to lignins obtained as a byproduct in wood pulp manufacturing CONCLUSIONS: The proposed reaction strategy, with two steps (thermal and catalytic) in series, valorizes the crude bio-oil by solving the problems caused by the polymerization of phenolic compounds, which are obtained in the pyrolysis of the lignin contained in lignocellulosic biomass. Given that a byproduct (pyrolytic lignin) is obtained with similar properties to the lignin from wood pulping manufacturing, the perspectives for the viability of lignocellulosic biomass valorization are promising, which is essential for furthering its implementation in biorefinery processes.

Matsushita, Kohei published the artcileA 13-week subchronic toxicity study of vanillin propylene glycol acetal in F344 rats, Recommanded Product: 2-Methoxy-4-(4-methyl-1,3-dioxolan-2-yl)phenol, the publication is Food and Chemical Toxicology (2019), 110643, database is CAplus and MEDLINE.

Vanillin propylene glycol acetal (VPGA) has been used as a flavoring agent. Here, we performed a 13-wk subchronic toxicity study of VPGA in F344 rats with oral administration by gavage at doses of 0, 100, 300, and 1000 mg/kg body weight (BW)/day. In the 1000 mg/kg BW group, loss of vigorous activity and listlessness immediately after administration were observed for both sexes throughout the exptl. period. Reduction of body weight gain was noted in both sexes at 1000 mg/kg BW. Serum biochem. demonstrated significant increases in total protein, albumin, total cholesterol, calcium, inorganic phosphorus, and γ-glutamyl transpeptidase in both sexes at 1000 mg/kg BW and increases in the albumin/globulin ratio and urea nitrogen in the male 1000 mg/kg BW group. A significant increase in relative liver weight was detected in both sexes at 1000 mg/kg BW. Histopathol., centrilobular hepatocellular hypertrophy in the liver was observed in both sexes at 1000 mg/kg BW. In addition, the incidence of fatty changes in hepatocytes in the male 1000 mg/kg BW group was decreased compared with that in the control. Based on these results, the no-observed-adverse-effect level for VPGA was evaluated to be 300 mg/kg BW/day for both sexes in the current study.
