Synthesis of fifteen C-4-aroyl-C-5-aryl-N-1-(5 ‘-deoxythymidin-5 ‘-yl)-1,2,3-triazoles have been reported starting from azidation of 5 ‘-p-toluenesulfonyloxythymidine followed by azide-alkene oxidative cycloaddition reaction of the resulted 5 ‘-azido-5 ‘-deoxythymidine with 1,3-diarylpropenones in dimethylformamide (DMF) in the presence of tetra-n-butylammonium hydrogen sulfate (n-Bu4N+HSO4-, TBAHS) as catalyst in 60 to 79% overall yields. Further, they were also synthesized by one pot sequential reaction of tosylated thymidine with sodium azide in DMF and then with 1,3-diarylpropenones in presence of n-Bu(4)N(+)HSO(4)(-)in superior yield of 70 to 95% than 60 to 79% in two step procedure. All fifteen synthesized compounds were screened for theirin vitroantiMycobacterium tuberculosisactivity against sensitive reference strain H37Rv and multi drug resistant (MDR) clinical isolate 591, and found to exhibit minimum inhibitory concentration (MIC) ranging from 2 to 15 mu g/mL, which was equivalent to the MIC of first line anti-tubercular drug streptomycin. All compounds qualify for their drug likeness when their physicochemical parameters were assessed using online MolSoft and Lipinski filter software, except their molecular weight. The cytotoxicity of potent compounds evaluated human monocytic cell line THP-1 by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay was found to be less as compared to the first line drug, isoniazid.

Indoles are one of the most valuable nucleophiles in Michael additions catalyzed by a proper Lewis acid. In this paper, we found that a cationic iron salt is effective to carry out the Michael addition of indoles. beta-Mono- and disubstituted enones reacted smoothly with indoles under our conditions. The cationic iron catalyst is very active, and the maximum TON was up to 425. Moreover, cationic iron-catalyzed conditions enabled a chemoselective Michael addition of a substrate possessing both enone and alpha,beta-unsaturated ester moieties.

The synthesis of phytol-derived gamma -butyrolactones as well as their evaluation for deterrent activity towards peach-potato aphid Myzus persicae and antiproliferative activity against four selected cancer cell lines are reported. Products were obtained in good yields (19-96%) and their structures were fully characterized by spectroscopic data (NMR, HRMS). Four synthesized delta -halo-gamma -lactones (4-7) are new and have not been previously described in the literature. In the choice test phytol (1) appeared deterrent to M. persicae, whereas modifications of its structure did not cause the avoidance of the treated leaves by the aphids. In contrast, aphids were attracted to the leaves treated with the new trans-delta -chloro-gamma -lactone (6). Electrical Penetration Graph (EPG) technique applied to explore the aphid probing and feeding activity revealed that neither phytol nor lactone 6 affected aphid probing and the consumption of phloem sap, which means that both phytol and the lactone 6 might have acted as postingestive modifiers of aphid behavior. The results of in vitro antitumor assays showed that obtained phytol derivatives exhibit cytotoxic activity against studied cancer cell lines (leukemia, lung and colon carcinoma and its doxorubicin resistant subline). Halolactones 4-6 were identified as the compounds, which arrest cell cycle of leukemia cells mainly in G2/M and S phases.

Name: 1,1,1-Triethoxyethane. I found the field of Chemistry very interesting. Saw the article Site-Selective 1,1-Difunctionalization of Unactivated Alkenes Enabled by Cationic Palladium Catalysis published in 2019.0, Reprint Addresses Baik, MH; Hong, S (corresponding author), Korea Adv Inst Sci & Technol, Dept Chem, Daejeon 34141, South Korea..

A palladium(II)-catalyzed 1,1-difunctionalization of unactivated terminal and internal alkenes via addition of two nucleophiles was developed using a cationic palladium(II) complex. The palladacycle generated in situ as a result of a regioselective addition of a nucleophile to the alkene can readily undergo regioselective beta-hydride elimination and migratory insertion with a cationic palladium catalyst. The resulting eta(3)-pi-allyl palladium(II) complex is the key intermediate that reacts with a second nucleophile to furnish the desired 1,1-difunctionalization of the alkene. Under the optimized reaction conditions, a wide range of indoles and anilines add to alkene units of 3-butenoic or 4-pentenoic acid derivatives to afford the synthetically useful gamma,gamma- or delta,delta-difunctionalized products with excellent regiocontrol. Furthermore, by employing internal hydroxyl or acid groups and external carbon nucleophiles, this transformation enables unsymmetric 1,1-difunctionalization to forge challenging and important oxo quaternary carbon centers. Combining experiments and DFT calculations on the mechanism of the reaction is investigated in detail.

A highly enantioselective three-component hydroacyloxylation/1,4-conjugate addition ofortho-hydroxybenzyl alcohols, ynamides and carboxylic acids was developed under mild reaction conditions in the presence of a chiralN,N ‘-dioxide/Sc(OTf)(3)complex, which went throughin situgeneratedortho-quinone methides with alpha-acyloxyenamides, delivering a range of corresponding chiral alpha-acyloxyenamides derivatives containinggem(1,1)-diaryl skeletons in moderate to good yields with excellenteevalues. The scale-up experiment and further derivation showed the practicality of this catalytic system. In addition, a possible catalytic cycle and transition state model was proposed to elucidate the origin of the stereoselectivity based on X-ray crystal structure of the alpha-acyloxyenamide intermediate and product.

Product Details of 94-41-7. I found the field of Food Science & Technology very interesting. Saw the article Zuccagnia-type Propolis from Argentina: A potential functional ingredient in food to pathologies associated to metabolic syndrome and oxidative stress published in 2020.0, Reprint Addresses Isla, MI (corresponding author), CONICET UNT, Inst Bioprospecc & Fisiol Vegetal INBIOFIV, RA-4000 San Miguel De Tucuman, Tucuman, Argentina.; Isla, MI (corresponding author), Univ Nacl Tucuman, Fac Ciencias Nat, RA-4000 San Miguel De Tucuman, Tucuman, Argentina.; Isla, MI (corresponding author), Fdn Miguel Lillo, Area Bot, Inst Morfol Vegetal, RA-4000 San Miguel De Tucuman, Tucuman, Argentina.. The CAS is 94-41-7. Through research, I have a further understanding and discovery of Chalcone.

The effect of Argentine propolis extracts against enzymes related to metabolic syndrome and oxidative stress, as well as the botanical origin of raw propolis, were studied. Histological and chemical analyses of propolis samples revealed that the botanical origin isZuccagnia punctata, an Argentine medicinal plant. The melissopalynological analysis showed both pollen grains ofZ. punctataand the other plant species. This result indicates that the differences found in the botanical remains compared to the palynological studies may have been caused by the bees selecting resinous shrubs mainly ofZ. punctatafor the production of propolis and other plants with flowers for the production of honey. The richness of propolis was remarkable in two flavonoid precursors (2 ‘,4 ‘-dihydroxy-3 ‘-methoxychalcone, 2 ‘,4 ‘-dihydroxychalcone), the major chemical components ofZ. punctata. The hydroalcoholic extracts of Argentine propolis andZ. punctatawere able to inhibit enzymes associated with the metabolic syndrome, including alpha-glucosidase, alpha-amylase and lipase, with IC(50)values between 7 to 14, 37 to 48, and 13 to 28 mu g/mL, respectively. Biological activity was mainly attributed to chalcones. Oxygen and nitrogen reactive species scavenging activity was determined by the assays of superoxide radical (O-2(center dot-)), hydroxyl radical (HO center dot), hydrogen peroxide (H2O2), nitric oxide (NO center dot), and cation radical (ABTS(center dot+)). Results showed SC(50)values between 115 to 278, 12.50 to 46; 39 to 92; 50 to 104.50 and 23 to 33.75 mu g/mL, respectively. This study suggests for the first time that propolis from Argentina is highly effective in inhibiting enzymes related to the metabolic syndrome and in free-radical scavenging that would justify its use as a dietary supplement or as a functional ingredient in special food. Practical Application Propolis from Catamarca, Argentina, is traditionally used as medicine and food. Its botanical origin isZuccagnia punctata, an endemic plant species popularly used as a medicine in Argentina. Propolis has the ability to regulate the activity of enzymes involved in the carbohydrate and lipid metabolism, and consequently in metabolic syndrome. Besides, its antioxidant capacity makes it a natural product that can be used as a dietary supplement or as a functional ingredient in special foods. It is important to highlight that in the Argentine Food Code, propolis was incorporated in 2008 as a dietary supplement and the present results give major added value to this product.
