The phytochemical studies on the aerial parts of Digitalis davisiana Heywood led to the isolation of three undescribed phenylethanoid glycosides named as digidavisoside A (5), digidavisoside B (7), and davisoside (8), along with 9 known compounds, ferruginoside B (1), isolugrandoside (2), lugrandoside (3), maxoside (4), 3 ””-O-methylmaxoside (6), trans-lamiuside E (9), digiciliside B (10), p-hydroxyacetophenone (11), and chrysoeriol (12). For the first time compound 11 was reported for Digitalis genus. The chemotaxonomical significance of these compounds in Plantaginaceae family was evaluated and 3′-O-glucosyl substituted phenylethanoid glycosides 4-8 and 10 were found to be chemotaxonomically important for the family. Cytotoxic activity of the aqueous fraction of the methanolic extract was also tested against HEp-2 (human larynx epidermoid carcinoma) and HepG2 (human hepatocellular carcinoma) cancer cell lines. The aqueous fraction showed stronger cytotoxicity on HEp-2 cells than on HepG2. Therefore, the cytotoxic activity of 1-4, 6, 7 and 9 were tested against HEp-2 and L929 (mouse fibroblast cell) cell lines. Other isolated compounds could not be tested due to their insufficient amount. The results were evaluated in the point of structure-activity relationships. IC50 values against HEp-2 cells were established in a range of 71.9-220 mu M. Maxoside (4), isolugrandoside (2) and lugrandoside (3) showed higher cytotoxicity against HEp.2 cell line than other isolated compounds.

The structure-based design of some CDK2 inhibitors with a 3-(benzylidene)indolin-2-one scaffold as potential anticancer agents was realized. Target compounds were obtained as E/Z mixtures and were resolved to corresponding E- and Z-diastereomers. In silico studies using MOE 2019.01 software revealed better docking on the targeted enzyme for the Z-diastereomer compared to the E-one. A time-dependent kinetic isomerization study was carried out for the inversion of E/Z diastereomers in DMSO-d(6) at room temperature, and were found to obey the first order kinetic reactions. Furthermore, a determination of the kinetic inter-conversion rate order by graphical analysis method and calculation of the rate constant and half-life of this kinetic process were carried out. For the prediction of the stability of the diastereomer(s), a good multiple regression equation was generated between the reaction rates of isomerization and some QM parameters with significant p value.

Species of herbaceous flowering perennial plant of the family Campanulaceae such as Platycodon grandiflorum (P. grandiflorum) and Codonopsis lanceolata (C. lanceolata) widely used in traditional medicine to treat different diseases. In spite of different medicinal results after consumption of the plants, it is hard to distinguish between two of them, because of their similar morphological characteristics. In this study, a gas chromatography-mass spectrometry (GC-MS) – based metabolite profiling approach was performed and examined to discriminate tuberous roots of P. grandiflorum and C. lanceolate for medicinal purposes. Two basic approaches for sample preparation, headspace solid-phase microextraction (HS-SPME) and solvent extraction were adopted. Multivariate statistical techniques, such as orthogonal partial least-squares discriminant analysis (OPLS-DA) plots showed significant differences between P. grandiflorum and C. lanceolata for polar primary and volatile organic metabolites. A number of potential candidates were suggested as the chemomarkers for discrimination of two plants.

The Name is 4′-Hydroxyacetophenone. Through research, I have a further understanding and discovery of 99-93-4.

The antioxidant activity of Sage leaf (SL) and Bay leaf (BL) extracts was studied. Both plants were extracted using water and ethanol at different concentration, and the antioxidant activity was measured by ABTS [2,2′-azinobis(3-ethylbenzothiazoline-6-sulfonic acid)] radical cation scavenging and reducing power (RP) methods. In both cases 60% and 80% ethanolic extracts of Sage and Bay leaves showed the highest activity and were incorporated into multilayer films. The initial concentration for 60% ethanolic extracts of Sage and Bay leaves to scavenge 50% of free radical ABTS were 5.67 +/- 0.26 mu g x mL(-1) and 18.68 +/- 0.16 mu g x mL(-1) respectively, whereas for 80% ethanolic extracts the concentrations were 7.96 +/- 0.02 and 14.65 +/- 0.59 mu g x mL(-1) respectively. The initial concentrations of ethanolic 60% extracts of Sage and Bay leaves to allow absorbance 0.5 for reducing power were 35.38 +/- 0.19 mu g x mL(-1) and 91.43 +/- 2.84 mu g x mL(-1) respectively, while for 80% ethanolic extracts of Bay and Sage leaves were 46.01 +/- 1.21 mu g x mL(-1) and 85.47 +/- 0.9 mu g x mL(-1) respectively. Then, the multilayer films were exposed to a gas stream enriched with free radicals to evaluate the free radicals scavenging. The new packaging with 60% ethanolic Sage extract exhibited the highest activity with low percentage of hydroxylation (69.64 +/- 6.86%) followed by that with 80% ethanolic extract for both Bay (85.49 +/- 5.3%) and Sage (87.09 +/- 3.93%) leaves extracts. The ability of two active packaging built with 60% ethanolic Sage extract and 80% ethanolic Bay extract to inhibit lipid oxidation of fried potatoes was studied by measuring secondary lipid oxidation products using thiobarituric acid reactive substances (TBARS). Significant lower value of Malondialdehyde (MDA) was obtained for fried potatoes stored in active packaging built with ethanolic 60% extract of Sage and 80% ethanolic extract of Bay leaves (0.342 +/- 0.01 and 0.392 +/- 0.02 mu g MDA x g(-1) respectively) at 40 degrees C for 20 days compared to the control (0.568 +/- 0.03 mu g MDA x g(-1)). Lipid oxidation decreased 40% and 31% for packaging with 60% Sage and 80% Bay ethanolic extracts respectively. The UPLC-MS-QTOF analysis of Sage and Bay leaves extracts revealed the presence of phenolic acids, tannins, flavonoids, and terpenoids. Migration tests from active materials demonstrated the absence of migration.

Recently I am researching about ACTIVATION; RHODIUM; AIR; FUNCTIONALIZATION; DERIVATIVES; BONDS, Saw an article supported by the National NSF of ChinaNational Natural Science Foundation of China (NSFC) [21432005, 21672154, 21871193]; Comprehensive Training Platform of Specialized Laboratory, College of Chemistry, Sichuan University. SDS of cas: 98-17-9. Published in AMER CHEMICAL SOC in WASHINGTON ,Authors: Zhang, LQ; Wang, YB; Shi, Y; Wu, YM; Lan, JB; Ma, WX; You, JS. The CAS is 98-17-9.

An urgent yet challenging task is to overcome the limitations in substrate scope and regio- and chemoselectivity in the oxidative couplings between two arenes for the construction of unsymmetrical 2,2′-difunctional biaryls with diverse application requirements. In this work, a co-oxidant-free Rh(I)/Zn(NTf2)(2)/air catalytic system has been developed for dual chelation-assisted oxidative C-H/C-H cross-couplings between two anilines, between two phenols, and between phenols and anilines, which enables rapid assembly of rich libraries of 2,2′-bianilines, 2,2′-biphenols, and 2′-aminobiphenyl-2-ols. This protocol features air as the sole oxidant, complete regioselectivity, high chemoselectivity, low molar ratio of substrates (even 1:1), convenient operation, and scale-up synthesis. The established catalytic system is tolerant of the substrates having both electron-donating and electron-withdrawing substituents at different positions of the aryl ring. This work further discloses that the chemoselectivity of cross-coupling over homocoupling mainly relies on a suitable combination of two directing groups (i.e., a pair of strongly and weakly coordinating directing groups) rather than the electronically distinct properties between two substrates, which provides an inspiration for designing the matching directing group pair for the dual chelation-assisted oxidative Ar-H/Ar-H cross-couplings. Thus, this strategy allows the highly chemoselective cross-coupling between electronically similar coupling partners, which represents a challenging task in the oxidative Ar-H/Ar-H cross-coupling reactions.

I found the field of Chemistry very interesting. Saw the article Selective Synthesis of Secondary and Tertiary Amines by Reductive N-Alkylation of Nitriles and N-Alkylation of Amines and Ammonium Formate Catalyzed by Ruthenium Complex published in 2019.0. HPLC of Formula: C7H8O, Reprint Addresses Nikonov, GI (corresponding author), Brock Univ, Chem Dept, 1812 Sir Isaac Brock Way, St Catharines, ON L2S 3A1, Canada.. The CAS is 100-51-6. Through research, I have a further understanding and discovery of Benzyl Alcohol

A new ruthenium catalytic system for the syntheses of secondary and tertiary amines via reductive N-alkylation of nitriles and N-alkylation of primary amines is proposed. Isomeric complexes 8 catalyze transfer hydrogenation and N-alkylation of nitriles in ethanol to give secondary amines. Unsymmetrical secondary amines can be produced by N-alkylation of primary amines with alcohols via the borrowing hydrogen methodology. Aliphatic amines were obtained with excellent yields, while only moderate conversions were observed for anilines. Based on kinetic and mechanistic studies, it is suggested that the rate determining step is the hydrogenation of intermediate imine to amine. Finally, ammonium formate was applied as the amination reagent for alcohols in the presence of ruthenium catalyst 8. Secondary amines were obtained from primary alcohols within 24hours at 100 degrees C, and tertiary amines can be produced after prolonged heating. Secondary alcohols can only be converted to secondary amines with moderate yield. Based on mechanistic studies, the process is suggested to proceed through an ammonium alkoxy carbonate intermediate, where carbonate acts as an efficient leaving group.

4-(4-Trifluoromethylphenyl)-2,6-bis[4-(4-amino-2-trifluoromethylphenoxy)phenyl]pyridine (9FPBAPP), as a new aromatic diamine, was prepared by a modified Chichibabin reaction of 4-(4-nitro-2-trifluoromethylphenoxy)acetophenone with 4-triflouromethylbenzaldehyde, followed by a catalytic reduction. A series of fluorinated poly(ether imide)s containing pyridine and/or phenylphosphine oxide moieties were prepared from bis(3-aminophenyl)phenylphosphine oxide (BAPPO), 2,2 ‘-bis(3,4-dicarboxyphenyl)hexafluoropropane dianhydride (6FDA), and 9FPBAPP via a conventional two-step thermal imidization procedure with various mole ratios of BAPPO and 9FPBAPP. All the polymers were amorphous and soluble in common organic solvents such as N,N-dimethylacetamide and N-methyl-2-pyrrolidone and had T-g’s of 277-285 degrees C, 5% weight loss temperature of 521-550 degrees C in nitrogen. Furthermore, high char yields and good limited oxygen index values indicated that these polymers exhibited good thermal stability and flame-retardant property. Tough and flexible polymer films also had good mechanical properties with tensile strengths of 75-99 MPa, tensile moduli of 1.1-1.6 GPa, and elongations at break of 12%-24% and low dielectric constants of 2.81-3.53 (1 MHz), as well as high optical transparency with the ultraviolet cutoff wavelength in the range of 350-384 nm.
