Alsayed, Shahinda S. R.;Lun, Shichun;Luna, Giuseppe;Beh, Chau Chun;Payne, Alan D.;Foster, Neil;Bishai, William R.;Gunosewoyo, Hendra research published 《 Design, synthesis, and biological evaluation of novel arylcarboxamide derivatives as anti-tubercular agents》, the research content is summarized as follows. Our group has previously reported several indolecarboxamides exhibiting potent antitubercular activity. Herein, we rationally designed several arylcarboxamides based on our previously reported homol. model and the recently published crystal structure of the mycobacterial membrane protein large 3 (MmpL3). Many analogs showed considerable anti-TB activity against drug-sensitive (DS) Mycobacterium tuberculosis (M. tb) strain. Naphthamide derivatives 13c and 13d were the most active compounds in our study (MIC: 6.55, 7.11 microM, resp.), showing comparable potency to the first line anti-tuberculosis (anti-TB) drug ethambutol (MIC: 4.89 microM). In addition to the naphthamide derivatives, we also identified the quinolone-2-carboxamides and 4-arylthiazole-2-carboxamides as potential MmpL3 inhibitors in which compounds 8i and 18b had MIC values of 9.97 and 9.82 microM, resp. All four compounds retained their high activity against multidrug-resistant (MDR) and extensively drug-resistant (XDR) M. tb strains. It is worth noting that the two most active compounds 13c and 13d also exhibited the highest selective activity towards DS, MDR and XDR M. tb strains over mammalian cells [IC₅₀ (Vero cells) = 227 microM], indicating their potential lack of cytotoxicity. The four compounds were docked into the MmpL3 active site and were studied for their drug-likeness using Lipinski′s rule of five.

Diethyl ethoxymethylidenemalonate is a matrix effect reagent used in analytical chemistry. It is often used as a substrate for the cycloaddition process, which produces malondialdehyde and hydrochloric acid. The UV-absorption of the malondialdehyde can be measured to determine the concentration of the sample. Diethyl ethoxymethylidenemalonate is also used as a dna template in binding constants, where it binds with amines to form complexes that are then analyzed by light emission. It has been shown to have an inhibitory effect on gyrase and trifluoroacetic acid, both enzymes involved in DNA replication., 87-13-8.

Aiming at the development of novel chemotype of dual AURKA/B inhibitors, design and synthesis of three series of 4-anilinoquinoline derivatives I [R = H, 6-Br, 6-Me, 5,7-di-Cl; R¹ = NH₂, HNMe, O₂SMe; X = NH, SO₂] bearing a sulfonamide moiety was reported. The % inhibition of AURKA/B was determined for all target quinolines I, then compounds I showed more than 50% inhibition on either of the enzymes, were evaluated further for their IC₅₀ on the corresponding enzyme. In particular, compound I [R = 5,7-di-Cl; R¹ = HNMe; X = SO₂] displayed potent AURKA/B inhibitory activities with IC₅₀ of 0.93 and 0.09μM, resp. Also, I [R = 5,7-di-Cl; R¹ = HNMe; X = SO₂] emerged as the most efficient anti-proliferative analog in the US-NCI anticancer assay toward the NCI 60 cell lines panel, with broad spectrum activity against different cell lines from diverse cancer subpanels. Docking studies, confirmed that, the sulfonamide SO₂ oxygen was involved in a hydrogen bond with Lys162 and Lys122 in AURKA and AURKB, resp., whereas, the sulfonamide NH could catch hydrogen bond interaction with the surrounding amino acid residues Lys141, Glu260, and Asn261 in AURKA and Lys101, Glu177, and Asp234 in AURKB. Furthermore, N1 nitrogen of the quinoline scaffold formed an essential hydrogen bond with the hinge region key amino acids Ala213 and Ala173 in AURKA and AURKB, resp.

Allegretti, Paul A.;Horton, Timothy M.;Abdolazimi, Yassan;Moeller, Hannah P.;Yeh, Benjamin;Caffet, Matthew;Michel, Guillermina;Smith, Mark;Annes, Justin P. research published 《 Generation of highly potent DYRK1A-dependent inducers of human β-Cell replication via Multi-Dimensional compound optimization》, the research content is summarized as follows. Small mol. stimulation of β-cell regeneration has emerged as a promising therapeutic strategy for diabetes. Although chem. inhibition of dual specificity tyrosine-phosphorylation-regulated kinase 1A (DYRK1A) is sufficient to enhance β-cell replication, current lead compounds have inadequate cellular potency for in vivo application. Herein, we report the clin. stage anti-cancer kinase inhibitor OTS167 as a structurally novel, remarkably potent DYRK1A inhibitor and inducer of human β-cell replication. Unfortunately, OTS167’s target promiscuity and cytotoxicity curtails utility. To tailor kinase selectivity towards DYRK1A and reduce cytotoxicity we designed a library of fifty-one OTS167 derivatives based upon a modeled structure of the DYRK1A-OTS167 complex. Indeed, derivative characterization yielded several leads with exceptional DYRK1A inhibition and human β-cell replication promoting potencies but substantially reduced cytotoxicity. These compounds are the most potent human β-cell replication-promoting compounds yet described and exemplify the potential to purposefully leverage off-target activities of advanced stage compounds for a desired application.

Abel-Snape, Xavier;Wycich, Gina;Lautens, Mark research published 《 Synthesis of Indenes and Benzofulvenes via a Palladium-Catalyzed Three-Component Reaction》, the research content is summarized as follows. A palladium-catalyzed three-component domino reaction to access indene derivatives is reported. This reaction proceeds via the sequential formation of three bonds: the first two resulting from inter- and intramol. carbopalladation and the final bond arising from an attack by a terminating nucleophilic reagent. Modifying the starting tether on the iodoarene led to either indenes or benzofulvenes. Three termination variations were compatible with this sequence, which furnished products in moderate to good yields. The oxabicycle used in this work acts as an acetylene surrogate, which is revealed in a postcatalytic retro-Diels-Alder step. A diastereomerically enriched mixture of oxabicyclic derivatives allowed for preliminary results for the enantioselective synthesis of indenes.

Roasting is crucial for producing large-leaf yellow tea (LYT) as it substantially affects chem. composition and sensory quality. However, the effect of roasting degree on LYT flavor quality is not clear. To investigate the effect of roasting degree on LYT flavor, the odor profiles and sensory evaluations of LYTs produced with small fire, medium fire and old fire roasting (OF) were determined The OF was essential for the formation of LYT flavor with strong roasted, nutty, woody odors and weak fatty, fruity odors, and retaining high levels of GCG, total volatiles and heterocyclic compounds Furthermore, the characteristic crispy-rice-like odor was only found in LYT with OF treatment and burnt flavor was missing. 2,3-Diethyl-5-methylpyrazine, trans-β-ionone with odor activity value above 1600 and 39 resp. offered roasted, floral odors, resp. in LYT. The current results provide a scientific basis for understanding the reactions that occur during the conventional production of LYT.

Wuyi rock tea (WRT), is one kind of oolong tea and widely appreciated for its typical ′rock flavor′. The odor characteristics of WRT during processing were comprehensive investigated by gas chromatog.-mass spectrometry, sensory evaluation and odor activity value (OAV).

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds.

Polycrystalline nickel oxide is deposited on SiO2 substrates by alternating pulses of bis(2,2,6,6-tetramethylheptane-3,5-dionato)nickel(II) (Ni(thd)2) and H2O. The deposition process shows at. layer deposition (ALD) characteristics with respect to the saturation behavior of the two precursors at deposition temperatures up to 275 °C. The growth of nickel oxide is shown to be highly dependent on surface hydroxide groups, and a large excess of H2O is required to achieve saturation Throughout the deposition temperature range the amount of carbon in the film, originating from the metal precursor ligand, is in the range 1-2%. Above 275 °C ALD growth behavior is lost in favor of thermal decomposition of the metal precursor. The initial nucleation process is studied by at. force microscopy (AFM) and reveals nucleation of well-separated grains which coalesce to a continuous film after about 250 ALD cycles.
