Bickerton, Laura E.; Langton, Matthew J. published the artcile< Controlling transmembrane ion transport via photo-regulated carrier mobility>, Recommanded Product: (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is transmembrane ion transport photo regulated carrier.

Stimuli-responsive transmembrane ion carriers allow for targeted and controllable transport activity, with potential applications as therapeutics for channelopathies and cancer, and in fundamental studies into ion transport phenomena. These applications require OFF-ON activation from a fully inactive state which does not exhibit background activity, but this remains challenging to achieve with synthetic transport systems. Here we introduce a novel mechanism for photo-gating mobile ion carriers, which involves modulating the mobility of the carriers within the lipid bilayer membrane. By appending a membrane-targeting anchor to the carrier using a photo-cleavable linker, the carriers ion transport activity is fully switched off by suppressing its ability to shuttle between the two aqueous-membrane interfaces of the bilayer. The system can be reactivated rapidly in situ within the membrane by photo-triggered cleavage of the anchor to release the mobile ion carrier. This approach does not involve direct functionalization of the ion binding site of the carrier, and so does not require the de novo design of novel ion binding motifs to implement the photo-caging of activity. This work demonstrates that controlling the mobility of artificial transport systems enables precise control over activity, opening up new avenues for spatio-temporally targeted ionophores.

Bao, Jiyin; Liu, Haichun; Zhi, Yanle; Yang, Wenqianzi; Zhang, Jiawei; Lu, Tao; Wang, Yue; Lu, Shuai published the artcile< Discovery of benzo[d]oxazole derivatives as the potent type-I FLT3-ITD inhibitors>, Application of C19H34O2, the main research area is phenylamino benzooxazole preparation antitumor activity tyrosine kinase inhibitor SAR; AML; Benzo[d]oxazole; FLT3 inhibitor.

A series of compounds I [R1 = H, Me, F, MeO; R2 = diethylamino, piperidinyl, piperazin-1-yl, etc.; R3 = Ph, pyridin-3-yl, pyridin-4-yl, etc.] were designed and synthesized based on benzo[d]oxazole-2-amine scaffold to discover new potent Fms-like tyrosine kinase 3 inhibitors. During the medicinal chem. works, flexible mol. docking was used to provide design rationale and study the binding modes of the target compounds Through the mixed SAR exploration based on the enzymic and cellular activities, compound I [R1 = MeO; R2 = piperazin-1-yl; R3 = 3-carbamoylphenyl] was identified with potent FLT3-ITD inhibitory (IC50: 0.41 nM) and anti-proliferative (IC50: 0.037μM against MV4-11 cells) activities. And the binding mode of I [R1 = MeO; R2 = piperazin-1-yl; R3 = 3-carbamoylphenyl] with ”DFG-in” FLT3 was simulated by a 20-ns mol. dynamics run, providing some insights into further medicinal chem. efforts toward novel FLT3 inhibitors in AML therapy.

Singh, Sangeeta; Syme, Colin A.; Singh, Ashvani K.; Devor, Daniel C.; Bridges, Robert J. published the artcile< Benzimidazolone activators of chloride secretion: potential therapeutics for cystic fibrosis and chronic obstructive pulmonary disease>, Synthetic Route of 112-63-0, the main research area is chloride channel benzimidazolone preparation cystic fibrosis; structure activity benzimidazolone lung disease cystic fibrosis.

The diseases of cystic fibrosis (CF) and chronic obstructive pulmonary disease (COPD) are characterized by mucus-congested airways. Agents that stimulate the secretion of Cl- are anticipated to facilitate mucociliary clearance and thus be of benefit in the treatment of CF and COPD. Recently 1-EBIO (1-ethyl-2-benzimidazolinone or 1-ethyl-1,3-dihydro-2H-benzimidazol-2-one) was shown to stimulate chloride secretion albeit at relatively high concentrations (0.6-1 mM). The studies reported here were undertaken to develop a more potent benzimidazolone. Structure activity studies with 30 benzimidazolone derivatives revealed that Et and hydrogen groups at the 1 and 3 nitrogen positions, resp., were critical for the activation of hIK1 K+ channels and that other alkyl groups were not tolerated at these positions without some loss in potency. Substitutions at the 5 and 6 positions improved the potency of 1-EBIO. Compared with 1-EBIO, the most potent of these derivatives, DCEBIO (5,6-dichloro-1-ethyl-1,3-dihydro-2H-benzimidazol-2-one) was severalfold better in a 86Rb+ uptake assay, 20-fold better in short circuit current measurements on T84 monolayers, and 100-fold better in patch-clamp assays of hIK1 activity. Short circuit current studies revealed DCEBIO stimulates Cl- secretion via the activation of hIK1 K+ channels and the activation of an apical membrane Cl- conductance. The improved potency of DCEBIO strengthens the possibility that compounds in this class may be of therapeutic benefit in the treatment of CF and COPD.

Rose, P. E.; Benoit, W. R.; Adams, M. C. published the artcile< Tracer testing at Dixie Valley, Nevada, using pyrene tetrasulfonate, amino G, and fluorescein>, Application In Synthesis of 112-63-0, the main research area is tracer study geothermal reservoir fluid flow injection well Nevada.

A series of four tracer tests was recently conducted at the Dixie Valley, Nevada, geothermal reservoir in order to determine fluid-flow processes and to evaluate candidate tracers for use in hydrothermal systems. These tests have resulted in the first successful use of the compounds amino G and pyrene tetrasulfonate as tracers in a geothermal reservoir. The tracer candidates were first subjected to simulated hydrothermal conditions in laboratory reactors at temperatures as high as 300°C in order to determine their thermal stabilities. They were next injected as pulses into the target injection wells. Fluids from the surrounding production wells were then sampled and analyzed in order to determine injectate flow patterns. The tracer data indicate that injected fluids flow only to a cluster of production wells in the south-central portion of the field; no tracer was produced in the producers located in the northeast section of the reservoir. Tracer returns from fluids injected into one of the wells indicate a much shorter residence time and a more heterogeneous flow pattern than tracer fluids from the other three injectors.

Hawkins, Joel M.; Meyer, Axel; Nambu, Mitch published the artcile< Asymmetric bisosmylation of fullerene C60: novel chiral π-systems>, HPLC of Formula: 112-63-0, the main research area is stereoselective regioselective bisosmylation fullerene; fullerene osmium complex chiral; cinchona alkaloid stereoselective biosmylation fullerene.

Two isomers of C60(OsO4py2)2 are chiral by virtue of the substitution pattern on the icosahedral carbon cluster. Treatment of C60 with two equiv of OsO4 and five equiv of cinchona alkaloid derivative, followed by exchange of the chiral ligands for pyridine, gives the chiral (C2) isomers of C60(OsO4py2)2 with optical rotations up to 3700° and CD spectra which reflect the novel chiral band-shaped π-systems of these compounds The regiochem. and stereochem. of the bisosmylation of C60 appear to be controlled by attractive electronic interactions between the arene components of the cinchona alkaloid ligands and the fullerene surface.

Wang, Xiao-Le; Wang, Ya-Ting; Guo, Zhen-Yu; Zhang, Ning-Ning; Wang, Yuan-Yuan; Hu, Die; Wang, Zhen-Zhen; Zhang, Yi published the artcile< Efficacy of paeoniflorin on models of depression: A systematic review and meta-analysis of rodent studies>, Category: esters-buliding-blocks, the main research area is meta analysis Paeonia depression paeoniflorin human; Animal studies; Depression; Paeoniflorin; Systematic review; meta-Analysis.

Meta-anal. of paeoniflorin, a bioactive compound extracted from the traditional Chinese herb, Paeonia lactiflora Pall, has been demonstrated to possess efficient antidepressant activity in previous studies. Our systematic review and meta-anal. aimed to assess the effectiveness of paeoniflorin in relieving depressive-like behaviors in animal models. We searched for in vivo studies on the antidepressant effects of paeoniflorin in rodents using electronic databases from their inception to Apr. 2021. The measurements of animal behavioral tests, including the sucrose consumption, forced swimming, tail suspension, and open field tests, were regarded as the outcomes. Fourteen studies involving 416 animals met the inclusion criteria and were included in the meta-anal. Statistical anal. revealed remarkable differences between the paeoniflorin and control groups. Furthermore, the paeoniflorin group showed great efficiency in improving depressive-like symptoms of animals in the sucrose consumption, forced swimming, tail suspension, and open field tests. Our meta-anal. demonstrates that paeoniflorin can significantly improve depressive-like symptoms in animals and suggests that it can be a potential therapy for patients with depression in the future.

Shakouri, Zahra; Nazockdast, Hossein; Sadeghi Ghari, Hedayatollah published the artcile< Effect of the geometry of cellulose nanocrystals on morphology and mechanical performance of dynamically vulcanized PLA/PU blend>, Safety of (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is cellulose nanocrystal vulcanized PLA polyurethane elastomer blend mech property.

Effects of the addition of single but geometrically different cellulose nanocrystals (CNCs) namely cylindrical CNCs (ultrasonic treated), spherical CNCs (chem. treated) and rod-like CNCs (com.) on microstructural development and mech. performance of the thermoplastic vulcanizates (TPVs) based on polylactic acid/polyurethane prepolymer (80/20) were studied. It was shown that a fraction of PLA mols. reacted with PU mols. during the dynamic crosslinking process. This was confirmed by the results of gel content measurements which showed an appreciable amount of addnl. gel content. This phenomenon together with the dynamic vulcanization process facilitated the development of a dual-continuous morphol. in the TPV sample which was confirmed by the melt viscoelastic results and TEM micrographs. Interestingly, the addition of spherical CNCs to the TPV led to a remarkable enhancement in its toughness. A similar effect but to a lesser extent was observed in the TPV sample filled with cylindrical CNCs. These results could be explained in terms of a 3D percolated or interconnected network microstructure formed between finely dispersed CNCs localized in PLA and/or between CNCs and the PLA matrix. This fact was evidenced by observation of strong liquid-solid transition in the melt viscoelastic results, as well as TEM and AFM micrographs. On contrary to other counterparts, the rod-like CNCs had a weakening effect on toughness of the TPV which was attributed to their poor dispersion and/or formation of their aggregates which could act as stress concentrators. Moreover, DMTA results showed an almost similar reinforcing effect for the three CNCs on increasing the modulus of the TPV below Tg of the PU and partially compensated the PU reducing effect on modulus in the temperature range between the Tg of PU and PLA.

Alves, Alanderson Arthu Araujo; de Medeiros, Lucas Henrique Gomes; Feitosa, Filipe Xavier; de Sant’Ana, Hosiberto Batista published the artcile< Thermodynamic Properties of Biodiesel and Petrodiesel Blends at High Pressure and High Temperature and a New Model for Density Prediction>, Formula: C19H34O2, the main research area is thermodn property biodiesel petrodiesel blend density modeling.

This paper presents a new model to predict the d. of biodiesel + petrodiesel mixtures at high pressure and high temperature (HPHT) based on the Murnaghan equation of state, as a function of temperature, pressure, volumetric composition, and petrodiesel and biodiesel densities. This model was validated by using exptl. data from the literature, along with a new exptl. data set for biodiesel (grape seed, corn, and linseed) + petrodiesel, at high pressure (0.10-100.00 MPa) and high temperature (293.15-413.15 K) in a composition range of 0, 20, 40, 60, 80, and 100%volume These exptl. data were correlated by using the Tammann-Tait equation. From these data, the following derivative properties were determined: isothermal compressibility (κT), isobaric thermal expansibility (αP), internal pressure (pint), and the difference between pressure and volume heat capacities (cp – cv). Deviations obtained from the model proposed in this work (%AARD) were less than 0.50% for biodiesel + petrodiesel d. data.

Saticioglu, Izzet Burcin; Mulet, Magdalena; Duman, Muhammed; Altun, Soner; Gomila, Margarita; Lalucat, Jorge; Garcia-Valdes, Elena published the artcile< First occurrence and whole-genome comparison of Pseudomonas haemolytica isolated in farmed rainbow trout>, Category: esters-buliding-blocks, the main research area is rainbow trout Pseudomonas haemolytica occurrence whole genome comparison.

The isolation of Pseudomonas haemolytica from different habitats as well as its distribution over a wide geog. area, possible reservoir role for antibiotic resistance and zoonotic potential, all require the detailed characterization of P. haemolytica strains. In the present study, we describe 18 phenotypically similar strains isolated from the rainbow trout, Oncorhynchus mykiss (Walbaum, 1792). The strains were collected from seemingly healthy, symptomatic or moribund rainbow trout of all sizes, from fry to broodstock. The strains were morphol., phenotypically (API20 NE and VITEK 2) and chemotaxonomically characterized by their methyl-fatty acid content (FAME), and mass spectrometry (MALDI-TOF) by their protein profiles. The 16S rRNA sequence similarity values grouped them into the Pseudomonas fluorescens phylogenetic group of species. The 18 strains were compared to 6 other previously described P. haemolytica strains, 2 of which were isolated from milk products and 4 from chicken products. A multilocus sequence anal. was performed for all strains. Strain P45 was selected to represent the 18 new isolates for genomic comparisons by ANIb, and GGDC was used to confirm the identification at species level. The presence of genes related to antimicrobial resistance, secretion systems and virulence was also assessed using comparative genomic analyses. This is the first comprehensive report on P. haemolytica strains isolated from fish.
