Predicting Melting Points of Biofriendly Choline-Based Ionic Liquids with Molecular Dynamics

Featured Application The developed fully simulation-based melting point prediction method facilitates the design of novel green ionic liquids. Abstract In this work, we introduce a simulation-based method for predicting the melting point of ionic liquids without prior knowledge of their crystal structure. We run molecular dynamics simulations of biofriendly, choline cation-based ionic liquids and apply the method to predict their melting point. The root-mean-square error of the predicted values is below 24 K. We advocate that such precision is sufficient for designing ionic liquids with relatively low melting points. The workflow for simulations is available for everyone and can be adopted for any species from the wide chemical space of ionic liquids.

The asymmetric synthesis of (S,S)-methylphenidate hydrochloride via ring-opening of an enantiopure aziridinium intermediate with phenylmagnesium bromide

The key step in our synthetic strategy towards (S,S)-methylphenidate hydrochloride employs the ring-opening of an in situ formed aziridinium intermediate. Treatment of an alpha-hydroxy-beta-amino ester with methanesulfonic anhydride promoted aziridinium formation and the subsequent addition of phenyl-magnesium bromide resulted in stereospecific and regioselective ring-opening to give the corresponding alpha-phenyl-beta-amino ester with overall retention of configuration. Subsequent functional group manipulation followed by N-deprotection and cyclisation generated the piperidine ring within the target compound, and transesterification gave (S,S)-methylphenidate hydrochloride, in only 8 steps from 1,5-pentanediol, in 15% overall yield. These results demonstrate the synthetic utility of enantiopure aziridinium intermediates as substrates for the generation of stereodefined C-C bonds, and crucially this methodology provides access to alpha-substituted-beta-amino ester substrates that are not accessible via enolate alkylation chemistry. The strategy reported herein is potentially applicable to all possible stereoisomers of methylphenidate as well as differentially substituted analogues. (C) 2019 Elsevier Ltd. All rights reserved.

Synthesis of 3-HCF2S-Chromones through Tandem Oxa-Michael Addition and Oxidative Difluoromethylthiolation

A simple protocol for the synthesis of difluoromethylthiolated chromen-4-ones using elemental sulfur and CICF2CO2Na as the difluoromethylthiolating agent is described. Three-component reactions of 2′-hydroxychalcones, CICF2CO2Na, and sulfur under basic conditions using TEMPO as the oxidant afforded HCF2S-containing 4H-chromen-4-one and 9H-thieno[3,2-b]chromen-9-one derivatives in good yield. The protocol is practical and efficient, and the starting materials are cheap and readily available.

Influence of Polyol/Salt Additives on the Drug-Mediated Phase Separation and Thermodynamic Properties of Triton X-100

Herein, we investigated the impact of different additives [polyols (glucose, galactose, and maltose)/electrolytes (KCl, K2SO4, and K3PO4 center dot 7H(2)O)] on the interaction between quinolone antibiotic drug, ciprofloxacin hydrochloride (CFH), and Triton X-100 (TX-100) via the cloud point (CP) measurement technique. The magnitudes of CP of TX-100 were observed to be reduced with the enlargement of TX-100 concentration. The CP values show U-shaped variation as a function of CFH concentration in the aqueous medium. The CP values dwindle in the existence of electrolyte, which continues with the rise of electrolyte concentration. The observed CP values in the electrolyte medium follow the order CPK3PO4.7H2O > CPK2SO4 > CPKCl. The CP values reduced in the presence of organic additives (polyols) also. The executed magnitudes of Gibbs free energy (Delta G(c)degrees) of clouding were positive in all cases, signifying the nonspontaneous phenomenon. The Delta G(c)degrees values reduce with TX-100 concentration. The values of enthalpy of clouding (Delta H-c degrees) and entropy of clouding (Delta S-c degrees), as well as different transfer properties of thermodynamic parameters, were estimated and interpreted in detail. Excellent entropy-enthalpy compensation was observed in all cases.

Effect of Synthesis Parameters on the Color Performance of Blue CoAl2O4 Ceramic Pigment

Blue ceramic nano pigment of CoAl2O4 has been synthesized by a co-precipitation method. The reactions conditions (stirring time and stoichiometric ratio) for the preparation of precipitated compound and the calcination conditions (temperature and time) have been optimized for the proper particle synthesis. In addition, the effects of different capping agents (pyrrolidinone, N-cetyl-N,N,N-trimethylammonium bromide, triethylamine, and oleic acid) on the characteristic features of CoAl2O4 have been analyzed by X-ray diffraction and color analysis. Synthesized samples have been identified as spinel (CoAl2O4). The spectroscopic results indicate that minor changes have been seen and the desired electronic transitions in Co2+ in tetrahedral coordination have been achieved. The color performance of pigments has been increased and particle sizes have been decreased with the capping agent addition. The lowest b* values have been obtained in the TEA added samples. The crystallite sizes have been estimated by using the Scherrer equation. In comparison of the capping agent added samples, the smallest particles have been obtained in CTAB added samples.

A modified approach for the site-selective direct C-6 arylation of benzylated uracil

An efficient methodology is reported for the regioselective C-6 arylation of protected uracil via the palladium catalyzed C-H functionalization of 1-(4-methoxybenzyl)-3-methylpyrimidine-2,4(1H,3H)-dione with (hetero)aryl halides and boronic acids. Utilization of the Pd(OAc)(2)/Xantphos catalytic system with a stoichiometric amount of Cul and DBU as the base was vital for the success of this protocol. The methodology is facile and compatible with aryl bromides, iodides and boronic acids and hence affords broad substrate scope and diversity. (C) 2019 Elsevier Ltd. All rights reserved.

Glycogen phosphorylase B promotes cell proliferation and migration through PI3K/AKT pathway in non-small cell lung cancer

Objective Glycogen phosphorylase B (PYGB), the rate-determining enzyme in glycogen degradation, plays a critical role in progression of various tumors. The present study focused on the potential molecular mechanism toward PYGB in non-small cell lung cancer (NSCLC) progression. Methods Expression of PYGB in NSCLC tissues and cell lines was evaluated via quantitative real-time PCR (qRT-PCR), western blot and immunohistochemistry. Cell viability, proliferation and apoptosis were investigated using 3-(4,5-Dimethylthiazol)-2,5-diphenyltetrazolium bromide (MTT) assay, 5-bromo-2-deoxyuridine (BrdU) and flow cytometry, respectively. Cell migration and invasion ability were detected by wound healing and transwell invasion assays, respectively. The in vivo effect of PYGB on NSCLC tumor growth was determined via subcutaneous xenotransplanted tumor model. Results PYGB was upregulated in NSCLC tissues and cell lines, suggesting a poor prognosis in NSCLC patients. In vitro functional assays indicated that knockdown of PYGB suppressed cell viability, proliferation, migration and invasion, while promoted cell apoptosis in NSCLC. Mechanistically, we found that overexpression of PYGB could activate phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway, while these effects were effectively reversed by knockdown of PYGB. In vivo tumorigenesis and PI3K/AKT signaling pathway were also inhibited by PYGB knockdown. Conclusions Knockdown of PYGB suppressed NSCLC progression, suggesting PYGB as a novel biomarker and potential molecular therapeutic target for further investigation in NSCLC.
