Computed Properties of C7H8O. I found the field of Chemistry very interesting. Saw the article One-pot synthesis of benzotripyrrole derivatives from 1H-pyrroles published in 2019.0, Reprint Addresses Panda, PK (corresponding author), Univ Hyderabad, Sch Chem, Hyderabad 500046, India.. The CAS is 100-51-6. Through research, I have a further understanding and discovery of Benzyl Alcohol.

Herein, we report, for the first time, the synthesis of C-3h symmetric benzotripyrroles having unprotected pyrrolic nitrogens in a single step from a known starting material, i.e. 2-methyl-1H-pyrrole-3-carboxylates, and characterized the isolated intermediate compounds to elucidate the mechanism. Further, computational studies were performed to probe the dual descriptor and aromaticity to understand the reactivity of the pyrrole derivatives towards cyclization and the stability of the benzotripyrrole.

Ethnopharmacological relevance: Yin-Chen-Hao Tang (YCHT) has been a very popular, hepatoprotective three-herb formula with an unclear chemical base. Aim of this study: To reveal the hepatoprotective chemical base of oral-dosed YCHT, we bridged the hepatic disposition of six compounds in vivo and their hepatoprotection in vitro. Materials and methods: In vivo, following the oral administration of YCHT in normal and CCl4-induced liver injury rats, the determinations of chlorogenic acid, 4-hydroxyacetophenone, geniposide, genipin, rhein and emodin were conducted in the portal vein plasma, the liver, and the systemic plasma. In vitro, the hepatoprotective activities of these compounds were determined in the CCl4-induced HepG2 cells. Results: Consistent with the highest content in YCHT, geniposide had the highest exposure in vivo. Inconsistent with the negligible content, rhein, 4-hydroxyacetophenone, emodin and genipin showed substantial hepatic accumulations. In contrast, chlorogenic acid, an ingredient that has a high content in YCHT, elicited no hepatic exposure. In normal rats, the hepatic disposition prevented the compounds entering into the systemic plasma from the portal vein plasma by 44.9-100%, except for rhein. CCl4-induced liver injury caused a decreased hepatic exposure of 4-hydroxyacetophenone, rhein and emodin by 50%. In vitro, all six compounds exerted the hepatoprotection by increasing cell viability, decreasing hepatic marker enzymes and inhibiting lipid peroxidation at varying levels. Conclusion Geniposide, rhein, emodin, 4-hydroxyacetophenone and genipin directly resisted liver injury in oral-dosed YCHT, while chlorogenic acid likely played an indirect role. This study proved that YCHT exerted hepatoprotection through multiple components and multiple actions. However, close attention should be paid to the possible side effects and oral dosage of YCHT in clinics.

A new efficient approach to the synthesis of 6-alkenyl substituted pyridoxine derivatives has been developed. A series of 31 novel alkenyl pyridoxine derivatives, stilbene-based bioisosteric analogs of estradiol, were synthesized. In vitro cytotoxicity of the obtained compounds against MCF-7 (ER+) breast cancer tumor cells was studied using the MTT assay. The most active compounds with IC50, MCF-7 < 10 mu M were also tested for cytotoxicity in vitro against MDA-MB-231 (ER-) breast adenocarcinoma cells and conditionally normal human skin fibroblasts (HSF). The patterns of structure-antitumor activity relationships of the obtained compounds were analyzed. The most active compounds were found to contain a six-membered ketal ring, a methyl group in position 5, a 3,4-dimethoxystyryl fragment in positions 2 or 6 of the pyridoxine ring, and a trans-configuration of the double bond. Using the most active compound 5a as a representative cytotoxic agent, we have demonstrated that it has high specificity and antiproliferative activity against MCF-7 (ER+) tumor cells (IC50 < 5 mu M), and a higher therapeutic index compared to the reference compound raloxifene (48 versus 5.8). Compound 5a decreased the mitochondrial membrane potential and increased the level of reactive oxygen species in MCF-7 cells, but not MDA-MB-231 cells. Compound 5a did not affect the distribution of cell cycle phases and induced apoptosis in MCF-7 cells, but not MDA-MB-231. Unlike compound 5a, raloxifene decreased mitochondrial potential, increased the ROS level, and induced apoptosis in both MCF-7 and MDA-MB-231 cells, which indicated a lack of selectivity for cells with estrogen receptor expression. It was also shown that compound 5a reduced the level of ER alpha expression in cells to a lesser extent than raloxifene and, unlike the latter, did not activate the PI3K/Akt signaling pathway.

A decarboxylative protocol has been developed toward a range of carbocycles. The key success is based on the use of a batch of newly designed cyclic carbonates as substrates that can provide carbon-carbon zwitterion intermediate under palladium catalysis. The kinetics of the reactions are controllable toward either strained seven- or thermodynamically more favored five-membered carbocycles. The release of this chemistry will shed light on the synthesis of complex and valuable cyclic structures.

Novel layered double hydroxides (LDHs) were prepared by a co-precipitation method and characterised using X-ray diffraction (XRD), Fourier transformed infrared spectroscopy (FT-IR), Thermogravimetric analysis (TGA) and scanning electron microscopy (SEM). As-prepared LDH derived catalysts were first evaluated in the gas-phase conversion of methanol. The results indicate that LDH derived materials act as selective catalysts towards dimethyl ether (DME), methane or light olefins formation, depending on their chemical composition. For instance, CuAlOx showed a high selectivity in DME up to 88 %, whilst CuCoOx converted methanol to CH4, C3H8 and DME. NiFeOx allowed achieving a full methanol conversion selectively into CH4 during at least 1800 min. Besides, Ni and Cu-LDHs were successfully tested in the liquid phase benzyl alcohol (BzOH) oxidation leading to more than 50 % conversion. NiAl-LDH appeared as the best catalyst for benzaldehyde production with a 71 % conversion and 100 % selectivity.

A sustainable boron-based catalytic approach for chemoselective N-alkylation of primary and secondary aromatic amines and amides with primary, secondary, and tertiary benzylic alcohols has been presented. The metal-free protocol operates at low catalyst loading, tolerates several functional groups, and generates H2O as the sole byproduct. Preliminary mechanistic studies were performed to demonstrate the crucial role of boron catalyst for the activation of the intermediate dibenzyl ether and to identify the rate-determining step.

Poly(2-acrylamido-2-methyl-1-propansulfonic acid) (p(AMPS) hydrogels were synthesized via free radical polymerization reaction technique under mild reaction conditions. The chemical structure of synthesized p(AMPS) anionic macroporous hydrogel was confirmed by Fourier transform infrared (FT-IR), scanning electron microscopy (SEM). Synthesized hydrogels were used as template for in situ metal nanoparticle preparation by using Ag(CH3COO) in H2O. Metal nanoparticles embedded p(AMPS)-Ag were visualized by TEM. The metal content of composites was estimated via atomic absorption spectroscopy (AAS). This metal-nanoparticle porous hydrogel composite was employed in the reduction of 4-nitrophenol and H-2 generation from hydrolysis of sodium borohydride (NaBH4). The activation energies, enthalpy, and entropy for 4-NP reduction and NaBH4 hydrolysis catalyzed by composite were determined. P(AMPS)-Ag composite was also used as catalyst in the aerobic oxidation of alcohols by emphasizing the effects of different parameters such as temperature, substituent effect, etc. Finally, the catalysts were easily recovered from the reaction media and it could be re-used for the other four runs without significant loss of activity.

The production of esters is largely influenced by functional gene expressions and the nutrition status of grape must. In this study, the effects of unsaturated fatty acids (UFAs) mixture (including linoleic acid, oleic acid and linolenic acid) on volatile esters of wine fermented with T73::ATF1 (overexpressing ATFI-encoded alcohol acetyltransferases) and T73::EEB (overexpressing EEB1-encoded acyl-CoA: ethanol O-acyltransferases) were investigated in alcoholic fermentation, respectively. The inoculation of T73::ATF1 into UFAs added juice significantly increased acetate esters production (ethyl acetate, isoamyl acetate and phenylethyl acetate) compared to in the control juice. The promotion on ethyl esters biosynthesis was also found in T73::EEB1 when supple. mented with low level of UFAs, but the function became inhibition with the further increment of UFAs concentration. The levels of higher alcohols, medium fatty acids and the major genes expression (ADH1, BAT1, PDC1, ACC1, FAS1 and LAH1) were changed and varied among the both strains. These results indicated that UFAs can modulate the effect of overexpressing ATF1 and EEB1 on esters biosynthesis by influencing the substrates availability. The combination of increasing ATF1 and EEB1 expressions and modulating UFAs content is a potential means to increase the esters production and improve the aromatic quality of wines.

Essential oils and ethanolic extracts of seeds of seven organically and conventionally grown accessions (E1, E2, E3, E4, E5, E6, and E7) of fennel (Foeniculum vulgare Mill.) were examined for their chemical constituents, antioxidant and antibacterial activities. Accession E7 presented the highest essential oil yields of 4.30 +/- 0.45 and 3.24 +/- 0.46%, respectively, for organic and conventional mode. However, E6 noted the lowest ethanolic extract yield in the two modes of cultivation. Gas chromatography/mass spectrometry analysis of the essential oils revealed the presence of nine essential components in all plant materials. (E)-anethole, methyl-chavicol, fenchone, and limonene were highly abundant. A considerable antioxidant effect was shown for all accessions and a significant difference (p < .05) was reported in the mode of cultivation of essential oils and ethanolic extracts. Concerning antibacterial activity, the essential oils showed generally higher antibacterial activity on gram-positive and gram-negative bacteria than ethanolic extracts for organic and conventional fennel seeds. Practical applications Foeniculum vulgare is an aromatic plant widely used nowadays as flavoring as well as food preservative in foods, such as ice cream, meat, and fish dishes. In this context, the chemical composition and biological activities of essential oil and ethanolic extract from fennel seeds cultivated in organic and conventional modes were studied. Fennel seeds extracts presented a richness in polyphenols and flavonoids. In addition, they showed considerable antioxidant activity, while essential oils had a higher antibacterial activity. There is increase demand, nowadays, for such natural and safe products for future applications in the food industries.

The Pot, Atom, and Step Economy (PASE) approach is based on the Pot economy principle and unites it with the Atom and Step Economy strategies; it ensures high efficiency, simplicity and low waste formation. The PASE approach is widely used in multicomponent chemistry. This approach was adopted for the synthesis of previously unknown hydroxyquinolinone substituted chromeno[2,3-b]pyridines via reaction of salicylaldehydes, malononitrile dimer and hydroxyquinolinone. It was shown that an ethanol-pyridine combination is more beneficial than other inorganic or organic catalysts. Quantum chemical studies showed that chromeno[2,3-b]pyridines has potential for corrosion inhibition. Real time H-1 NMR monitoring was used for the investigation of reaction mechanism and 2-((2H-chromen-3-yl)methylene)malononitrile was defined as a key intermediate in the reaction.
