Selective inhibition of exclusively transcription-regulating PTEFb/CDK9 is a promising new approach in cancer therapy. Starting from lead compound BAY-958, lead optimization efforts strictly focusing on kinase selectivity, physicochem. and DMPK properties finally led to the identification of the orally available clin. candidate atuveciclib (BAY 1143572). Structurally characterized by an unusual benzyl sulfoximine group, BAY 1143572 exhibited the best overall profile in vitro and in vivo, including high efficacy and good tolerability in xenograft models in mice and rats. BAY 1143572 is the first potent and highly selective PTEFb/CDK9 inhibitor to enter clin. trials for the treatment of cancer.

Chu, Kevin L.; Koley, Somnath; Jenkins, Lauren M.; Bailey, Sally R.; Kambhampati, Shrikaar; Foley, Kevin; Arp, Jennifer J.; Morley, Stewart A.; Czymmek, Kirk J.; Bates, Philip D.; Allen, Doug K. published the artcile< Metabolic flux analysis of the non-transitory starch tradeoff for lipid production in mature tobacco leaves>, Electric Literature of 112-63-0, the main research area is nontransitory starch lipid production tobacco leaf triacylglycerol; (13)C isotope Labeling; Acyl-ACPs; Carbon partitioning; Metabolic flux analysis; Nicotiana tabacum (tobacco); Starch-triacylglycerol tradeoff.

The metabolic plasticity of tobacco leaves has been demonstrated via the generation of transgenic plants that can accumulate over 30% dry weight as triacylglycerols. In investigating the changes in carbon partitioning in these high lipid-producing (HLP) leaves, foliar lipids accumulated stepwise over development. Interestingly, non-transient starch was observed to accumulate with plant age in WT but not HLP leaves, with a drop in foliar starch concurrent with an increase in lipid content. The metabolic carbon tradeoff between starch and lipid was studied using 13CO2-labeling experiments and isotopically nonstationary metabolic flux anal., not previously applied to the mature leaves of a crop. Fatty acid synthesis was investigated through assessment of acyl-acyl carrier proteins using a recently derived quantification method that was extended to accommodate isotopic labeling. Anal. of labeling patterns and flux modeling indicated the continued production of unlabeled starch, sucrose cycling, and a significant contribution of NADP-malic enzyme to plastidic pyruvate production for the production of lipids in HLP leaves, with the latter verified by enzyme activity assays. The results suggest an inherent capacity for a developmentally regulated carbon sink in tobacco leaves and may in part explain the uniquely successful leaf lipid engineering efforts in this crop.

Kamoshita, Shione; Matsui, Saho; Suto, Nanako; Sakurai, Kaori published the artcile< Reactivity Analysis of New Multivalent Electrophilic Probes for Affinity Labeling of Carbohydrate Binding Proteins>, SDS of cas: 112-63-0, the main research area is electrophilic probe reactivity analysis affinity labeling carbohydrate binding protein; affinity labeling; carbohydrates; chemical probes; electrophiles; gold-nanoparticles; multivalency.

We have designed and synthesized six different multivalent electrophiles as carbohydrate affinity labeling probes. Evaluation of the reactivity of the electrophiles against peanut agglutinin (PNA) and Ricinus communis agglutinin (RCA) showed that p- and m-aryl sulfonyl fluoride are effective protein reactive groups that label carbohydrate binding lectins in a ligand-dependent fashion at a nanomolar probe concentration Anal. of the selectivity of affinity labeling in the presence of excess BSA as a nonspecific protein indicated that m-arylsulfonyl fluoride is a more selective protein-reactive group, albeit with attenuated reactivity. Further anal. showed that the labeling efficiency of the multivalent electrophilic probes can be improved by employing reaction conditions involving 25 °C instead of typically employed 4 °C. Both isomers of arylsulfonyl fluoride groups together represent promising affinity labels for target identification studies that could serve as more efficient alternatives to photoreactive groups.

Dutta, Arghya; Matsuda, Shoichi published the artcile< Identifying the Performance Limiters in High Areal-Capacity Li-Oxygen Battery at Subzero Temperatures>, Safety of (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is lithium oxygen battery subzero temperature.

Li-O2 batteries are found to show severe loss in energy d. at subzero temperatures Here we investigate and deconvolute several temperature dependent parameters of a high areal-capacity Li-O2 battery, and our analyses show that combined effects of electrode kinetics, diffusion of electroactive species in the electrolyte, and charge transport through the electrodes directly influence the temperature dependent average discharge potential of the cell. In contrast, the low capacity of Li-O2 cells at subzero temperatures is found to be the result of charge transport resistance in the Li2O2 layer and the diffusion limitation of electroactive species in the electrolyte.

Russell, Glen A.; Rhee, Jong Uk; Baik, Woonphil published the artcile< Electron transfer processes. Part 63. Reactions of p-nitrobenzyl halides with dialkyl phosphite anions in dimethyl sulfoxide>, COA of Formula: C19H34O2, the main research area is nitrobenzyl halide reaction dialkyl phosphite anion; solvent effect nitrobenzyl halide dialkyl phosphite.

The reactions of p-O2NC6H4CH2Cl with (RO)2PO- in Me2SO with R = Me, Et, Pr, Bu, CF3CH2, i-Pr, Ph involve the formation of p-O2NC6H4CH2P(O)(OR)2 by SN2 substitution followed by a further SRN1 p-nitro-benzylation of p-O2NC6H4CH[P(O)(OR)2]- and p-O2NC6H4C(CH2C6H4NO2-p)[P(O)(OR)2]-. With p-O2NC6H4CH2Br, the reactions proceed mainly to form p-O2NC6H4CH-2, which undergoes reaction with p-O2NC6H4CH2Br to form p-O2NC6H4CH2CH2C6H4NO2-p. Halophilic reaction of (RO)2PO- with p-O2NC6H4CH(CH3)X (X = Cl, Br) leading to the bibenzyl is the preferred reaction course. Reactions of (RO)2PO- or p-O2NC6H4CH[P(O)(OR)2]- with p-O2NC6H4CH2X in Me2SO do not form significant amounts of p-O2NC6H4CHX- that would yield p-O2NC6H4CH:CHC6H4NO2-p. However, p-Cl-C6H4CH[P(O)(OEt)]- readily abstracts the benzylic proton from p-O2NC6H4CH2X to form the stilbene, although p-O2NC6H4CH2Br reacts with p-O2NC6H4CH[P(O)(OR)2]- to form p-O2NC6H4CH(CH2C6H4No2-p)P(O)(OR)2 in a reaction mixture not inhibited by (t-Bu)2NO•.

Landwehr, Katherine R.; Hillas, Jessica; Mead-Hunter, Ryan; Brooks, Peter; King, Andrew; O’Leary, Rebecca A.; Kicic, Anthony; Mullins, Benjamin J.; Larcombe, Alexander N. published the artcile< Fuel feedstock determines biodiesel exhaust toxicity in a human airway epithelial cell exposure model>, HPLC of Formula: 112-63-0, the main research area is biodiesel fuel feedstock exhaust toxicity airway epithelial cell; Biodiesel; Exhaust exposure; Health; In vitro exposure model; Vehicle emissions.

Biodiesel is promoted as a sustainable replacement for com. diesel. Biodiesel fuel and exhaust properties change depending on the base feedstock oil/fat used during creation. The aims of this study were, for the first time, to compare the exhaust exposure health impacts of a wide range of biodiesels made from different feedstocks and relate these effects with the corresponding exhaust characteristics. Primary airway epithelial cells were exposed to diluted exhaust from an engine running on conventional diesel and biodiesel made from Soy, Canola, Waste Cooking Oil, Tallow, Palm and Cottonseed. Exhaust properties and cellular viability and mediator release were analyzed post exposure. The exhaust physico-chem. of Tallow biodiesel was the most different to diesel as well as the most toxic, with exposure resulting in significantly decreased cellular viability (95.8 ± 6.5%) and increased release of several immune mediators including IL-6 (+223.11 ± 368.83 pg/mL) and IL-8 (+1516.17 ± 2908.79 pg/mL) above Air controls. In contrast Canola biodiesel was the least toxic with exposure only increasing TNF-α (4.91 ± 8.61). This study, which investigated the toxic effects for the largest range of biodiesels, shows that exposure to different exhausts results in a spectrum of toxic effects in vitro when combusted under identical conditions.
