To a solution of ethyl 1-(2-chlorophenyl)-5-(4-chlorophenyl)-4-hydroxy-1H-pyrazole-3-carboxylate (20 g, 53 mmol) in DMF (100 mL) at 0 C. was added KOtBu (7.73 g, 69 mmol). The mixture was stirred at 0 C. for 45 minutes, then tert.-butyl 4-bromobutanoate (15.4 g, 69 mmol) was added at 0 C. The reaction mixture was allowed to warm to room temperature and stir overnight. The mixture was portioned between ether and saturated aqueous NH4Cl. The organic solution was washed with water and saturated aqueous NaCl, dried over Na2SO4, and concentrated in vacuo. The residue was taken into hot cyclohexane. The mixture was allowed to stand for 72 hours. The solvent was decanted and the residue was washed with cold cyclohexane. The solid was then dried under high vacuum to yield 4-(3-tert.-butoxycarbonyl-propoxy)-1-(2-chloro-phenyl)-5-(4-chloro-phenyl)-1H-pyrazole-3-carboxylic acid ethyl ester (I-1a: 20.8 g). 1H NMR (400 MHz, CHLOROFORM-D) ppm 1.4 (s, 9H), 1.4 (t, J=7.1 Hz, 3H), 1.9 (m, 2H), 2.3 (t, J=7.5 Hz, 2H), 4.0 (t, J=5.9 Hz, 2H), 4.4 (q, J=7.1 Hz, 2H), 7.2 (m, 2H), 7.2 (m, 2H), 7.4 (m, 3H), 7.5 (m, 1H); m/z=519.0 (M+1).

Humic acids trigger the weak acids stress response in maize seedlings

Background: Plants primed by humic acids showed physiological and molecular response against different abiotic stresses without the presence of stressor agents (salinity, drought, heavy metal toxicity). It is plausible that humic acids themselves can act as chemical priming substances in plants. We hypothesized that humic acids can trigger the weak acids stress response in cell plants acidifying the cytosol and thus eliciting the transduction signalling response cascade. Methods: The dose-response curves of maize seedlings roots with different concentrations of humic, acetic and salicylic acids determined the most active and inhibitory concentration. These data were further used to evaluate changes on intracellular pH using BCECF-AM probe (2,7-bis(2-carboxyethyl)-5(and 6)-carboxyfluorescein, acetoxymethyl ester) and differential transcription level of genes related to weak stress response in plants by qPCR real time. Results: Humic acids like short chain organic acids decrease the intracellular pH showed by the increased fluorescence of BCECF probe. The drop in cytosolic pH promoted by humic acids was not transient. We observed a high level of protein kinases related to cell energy-sensing and transcription factors associated to transduction of stress signalling. Conclusion: The humic acids can be considered as a chemical priming agent, since in the appropriate concentration they can induce the typical plant abiotic stress response of weak acids inducing plant acclimation and enhancing the abiotic stress tolerance.

A Pichia biosensor for high-throughput analyses of compounds that can influence mosquito behavior

Mosquitoes utilize their sense of smell to locate prey and feed on their blood. Repellents interfere with the biochemical cascades that detect odors. Consequently, repellants are highly effective and resource-efficient alternatives for controlling the spread of mosquito-borne illnesses. Unfortunately, the discovery of repellents is slow, laborious, and error-prone. To this end, we have taken a giant stride toward improving the speed and accuracy of repellant discovery by constructing a prototypical whole-cell biosensor for accurate detection of mosquito behavior-modifying compounds such as repellants. As a proof-of-concept, we genetically engineered Pichia pastoris to express the olfactory receptor co-receptor (Orco) of Anopheles gambiae mosquitoes. This transmembrane protein behaves like a cationic channel upon activation by stimulatory odorants. When the engineered Pichia cells are cultured in calcium-containing Hank’s buffer, induction of the medium with a stimulatory odorant results in an influx of calcium ions into the cells, and the stimulatory effect is quantifiable using the calcium-sequestering fluorescent dye, fluo-4-acetoxymethyl ester. Moreover, the stimulatory effect can be titrated by adjusting either the concentration of calcium ions in the medium or the level of induction of the stimulatory odorant. Subsequent exposure of the activated Pichia cells to a repellant molecule inhibits the stimulatory effect and quenches the fluorescent signal, also in a titratable manner. Significantly, the modular architecture of the biosensor allows easy and efficient expansion of its detection range by co-expressing Orco with other olfactory receptors. The high-throughput assay is also compatible with robotic screening infrastructure, and our development represents a paradigm change for the discovery of mosquito repellants.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 110661-91-1 is helpful to your research. Category: esters-buliding-blocks.

Screening and characterization of a diverse panel of metagenomic imine reductases for biocatalytic reductive amination

Finding faster and simpler ways to screen protein sequence space to enable the identification of new biocatalysts for asymmetric synthesis remains both a challenge and a rate-limiting step in enzyme discovery. Biocatalytic strategies for the synthesis of chiral amines are increasingly attractive and include enzymatic asymmetric reductive amination, which offers an efficient route to many of these high-value compounds. Here we report the discovery of over 300 new imine reductases and the production of a large (384 enzymes) and sequence-diverse panel of imine reductases available for screening. We also report the development of a facile high-throughput screen to interrogate their activity. Through this approach we identified imine reductase biocatalysts capable of accepting structurally demanding ketones and amines, which include the preparative synthesis of N-substituted beta-amino ester derivatives via a dynamic kinetic resolution process, with excellent yields and stereochemical purities. High-throughput biocatalytic screening and metagenomics have been used to discover over 300 imine reductases (IREDs) and subsequently produce a sequence-diverse panel of IREDs suitable for optimizing the synthesis of chiral amines. Additional characterization identified biocatalysts that accommodate structurally demanding amines and ketones for enzymatic reductive aminations.

Fabrication and curing properties of o-cresol formaldehyde epoxy resin with reversible cross-links by dynamic boronic ester bonds

Conventional cured o-Cresol Formaldehyde Epoxy Resin (o-CFER) with permanent crosslink network is relatively stiff, brittle, and unrecyclable. In order to overcome these defects, herein 2,2′-(1,4-phenylene)-bis [4-mercaptan 1,3,2-dioxaborolane] (BDB) is employed as curing agent and a novel type of covalent adaptable network o-CFER is constructed by the reaction between thiols in BDB and epoxy groups in o-CFER. Obtained curing o-CFER vitrimers possess superior thermostability and good mechanical properties. Because of the transesterification of boronic ester bonds, o-CFER network topologies can be altered, contributing a self-healing ability and shape memory to the produced polymer. Besides, it is investigated the effects of the healing time and temperature on self-healing capability and achieved a healing efficiency of above 95% at 160 degrees C for 12 h. Moreover, through hot press, the pulverized samples of 8%C-o-CFER can be reshaped several times and mechanical properties of the recycled samples are well-restored even higher than those of pristine after being remolded at 200 degrees C for 60 min.

A generalized neural network model for the VLE of supercritical carbon dioxide fluid extraction of fatty oils

In the present work, a neural network (NN) model was developed for the precise prediction of the phase behavior of supercritical carbon dioxide (SC-CO2) and fatty oils. A total of 678 SC-CO2 + fatty oils vapor-liquid equilibrium datasets for fatty acids, methyl and ethyl esters plus 120 data points for further accuracy examinations were used. The Cascade-Forward scheme was used as the basic architecture for the NN model calculations and predictions. Comparison between the values of the average absolute deviation of the NN model and the most important existing models showed that the NN model outperforms the other alternatives. The overall AAD for CO2 mole fractions in liquid and vapor phases were obtained to be 1.516 and 0.312%, respectively.
