Helicity adaptation within a quadruply stranded helicate by encapsulation

The helicity of a quadruply stranded M2L4 helicate consisting of an aromatic amide bidendate ligand is flexible due to the twisting of the amide moieties and can be tuned by the encapsulated anions. This study reveals the multiple interplays and complementarities between the anions as well as between the anions and the helicate, which are synthetically responsive to the ultimate conformation of the helicate.

Modification of Oligopeptides on Aspartic Acid or Lysine Residues by Solid-Phase Synthesis through On-Resin Side-Chain Conjugation

On-resin side-chain conjugations of various moieties to oligopeptides were performed through an orthogonal protecting protocol using side-chain-protecting groups for aspartic acid or lysine that could be selectively removed on-resin. Various types of modification, such as PEGylation, biotinylation, glycosylation, or fluorophore-labeling of peptides, were realized by using this strategy. The formation of ester, amide, hydrazide, and thiourea bonds was accomplished through the on-resin conjugation. Our work provides an improved and convenient solid-phase synthetic protocol for the modification of oligopeptides on their aspartic acid or lysine residues. This is a universal and practical method that is expected to increase the potential application of peptide-related drugs.

Estimation of descriptors for hydrogen-bonding compounds from chromatographic and liquid-liquid partition measurements

Retention factors obtained by gas chromatography and reversed-phase liquid chromatography on varied columns and partition constants in different liquid-liquid partition systems are used to estimate WSU descriptor values for 36 anilines and N-heterocyclic compounds, 13 amides and related compounds, and 45 phenols and alcohols. These compounds are suitable for use as calibration compounds to characterize separation systems covering the descriptor space E = 0.2-3, S = 0.4-2.1, A = 0-1.5, B = 0.1-1.5, L = 2.5-10.0 and V = 0.5-2.2. Hydrogen-bonding properties are discussed in terms of structure, the possibility of induction effects, intramolecular hydrogen bonding and steric factors for anilines, amides, phenols and alcohols. The relationship between these parameters and observed descriptor values are difficult to predict from structure but facilitate improving the general occupancy of the descriptor space by creating incremental changes in hydrogen-bonding properties. It is verified that the compounds included in this study can be merged with an existing database of compounds recommended for characterizing separation systems. (C) 2017 Elsevier B.V.

Efficient synthesis, spectroscopic characterization and DFT based studies of novel 1-amide 4-sulfonamide-1,2,3-triazole derivatives

In the present study, for the first time 1-amide 4-sulfonamide-1,2,3-triazole scaffolds were synthesized by using an azide-alkyne Huisgen cycloaddition reaction. The target products were obtained in moderate to good yields (45-75%) by using catalytic Cul and green system H2O/EtOH. The easy availability of the inexpensive starting materials, avoiding isolation and handling of hazardous organic azides and mild reaction conditions make this method a valuable tool for generating functionalized 1,2,3-triazole derivatives. The unambiguous characterization of synthesized compounds was accomplished by using various spectroscopic techniques such as H-1 NMR, C-13 NMR, and FT-IR. The information regarding optimized geometry, were obtained by applying DFT/B3LYP-6-31G(d) method. The electrophilicity index, H-1 and C-13 chemical shift values, lithium and sodium ion affinities of the desired product 3b have been also calculated by the mentioned method. As a whole, the calculated results were found in close agreement to that of experimental data. The studies revealed that the compound 3b possesses good Li+ and Na+ affinity and cation pi interaction plays a vital role in the complexation of 3b. For the first time, nucleus-independent chemical shift index was used to confirm the cation pi interaction of 3b. (C) 2019 Elsevier B.V. All rights reserved.

Design, synthesis, biological evaluation, and modeling studies of novel conformationally-restricted analogues of sorafenib as selective kinase-inhibitory antiproliferative agents against hepatocellular carcinoma cells

Sorafenib is one of the clinically used anticancer agents that inhibits several kinases. In this study, novel indole-based rigid analogues of sorafenib were designed and synthesized in order to enhance kinase selectivity and hence minimize the side effects associated with its use. The target compounds possess different linkers; urea, amide, sulfonamide, or thiourea, in addition to different terminal aryl moieties attached to the linker in order to investigate their impact on biological activity. They were tested against Hep3B, Huh7, and Hep-G2 hepatocellular carcinoma (HCC) cell lines to study their potency. Among all the tested target derivatives, compound 1h exerted superior antiproliferative potency against all the three tested HCC cell lines compared to sorafenib. Based on these preliminary results, compound 1h was selected for further biological and in silico investigations. Up to 30 mu M, compound 1h did not inhibit 50% of the proliferation of WI-38 normal cells, which indicated promising selectivity against HCC cells than normal cells. In addition, compound 1h exerted superior kinase selectivity than sorafenib. It is selective for VEGFR2 and VEGFR3 angiogenesis-related kinases, while sorafenib is a multikinase inhibitor. Superior kinase selectivity of compound 1h to sorafenib can be attributed to its conformationally-restricted indole nucleus and the bulky N-methylpiperazinyl moiety. Western blotting was carried out and confirmed the ability of compound 1h to inhibit VEGFR2 kinase inside Hep-G2 HCC cells in a dose-dependent pattern. Compound 1h induces apoptosis and necrosis in Hep-G2 cell line, as shown by caspase-3/7 and lactate dehydrogenase (LDH) release assays, respectively. Moreover, compound 1h is rather safe against hERG. Thus, we could achieve a more selective kinase inhibitor than sorafenib with retained or even better antiproliferative potency against HCC cell lines. Furthermore, molecular docking and dynamic simulation studies were carried out to investigate its binding mode with VEGFR2 kinase. The molecule has a unique orientation upon binding with the kinase.

The impact of gamma-irradiation from radioactive liquid wastewater on polymeric structures of nanofiltration (NF) membranes

In this study, the impacts of gamma-irradiation from the lowand intermediate-level liquid radioactive wastewaters (LILW) to polyamide (PA) structures of nanofiltration (NF) membranes were investigated. As the gamma irradiation increased to 300 kGy in the aqueous solution at 5 bar, both the salt rejection and the water permeability of NF membranes were decreased from 95.6 +/- 0.1%-74.6 +/- 0.5%, and from 33.7 +/- 0.3 LMH to 21.4 +/- 0.5 LMH, respectively. The surface free energy and Young’s modulus of the membrane indicated the decrease in hydrophilicity and the increase in fragility of PA structure after gamma-irradiation. X-ray photoelectron spectroscopy and the streaming potential analysis exhibited that the gamma-irradiation resulted the increase in the cross-linked portion of the amide bonding from 28% to 45% due to the gamma-induced new bonding between unbound carboxylic groups and amine groups. Nuclear magnetic resonance analysis confirmed that the poly(pphenylene) in polyamide structure were changed to poly(cyclohexane) and poly(cyclohexene) by hydrogen radical disproportionation generated from the gamma-irradiated water, and it is responsible to the increase of the cross-linked PA structures. The decrease in salt rejection and water permeability is attributed to the aging of PA structures by gamma-irradiation, thus, should be carefully monitored during the treatment of LILW using NF membrane processes.

Enhanced butanol production from ammonium sulfite pretreated wheat straw by separate hydrolysis and fermentation and simultaneous saccharification and fermentation

Wheat straw (WS) was pretreated by ammonium sulfite (AS) for efficient acetone-butanol-ethanol (ABE) production by Clostridium acetobutylicum ATCC 824. Spent liquor containing the amides has the potential to be used for slow-release fertilizer production, and the solid fraction was readily for ABE fermentation. Compared to the results of separate hydrolysis and fermentation (SHF), relative higher ABE titer and yield were achieved in simultaneous saccharification and fermentation (SSF) using different level of AS pretreated WS (6%, 7.5%, 9% and 10.5%, w/v). As biomass loading in SHF increased from 6% to 10.5%, ABE (butanol) titer increased from 12.28 (7.52) to 17.75 (11.25) g/L, with ABE (butanol) yield reducing from 161 (98) to 133 (84) g/kg raw WS. For SSF, the maximum ABE (butanol) titer was obtained from 9% biomass loading. As biomass loading increased from 6% to 9%, ABE (butanol) titer increased from 17.13 (9.50) to 19.83 (12.64) g/L, with ABE (butanol) yield reducing from 224 (1 2 4) to 173 (1 1 0) g/kg raw WS. This study suggested that ABE production by SSF is viable to be conducted using AS pretreated WS.

Ultrafast N-H vibrational dynamics of hydrogen-bonded cyclic amide reveal by 2DIR spectroscopy

Hydrogen-bonding strongly influences the vibrational dynamics of the N-H stretch vibration, hence the molecular structure and dynamics. Therefore the N-H stretch vibration is an important probe to study hydrogen-bond dynamics as well as the molecular structure and dynamics, specially for the biological molecule. In this article, the dynamics and couplings of N-H stretching vibrations of biological molecules are investigated with linear infrared spectroscopy and ultrafast two-dimensional infrared (2DIR) spectroscopy with a model molecule 2-Pyrrolidinone. In solution, 2-Pyrrolidinone makes three different kinds of intermolecular hydrogen bonding, whose spectra have been collected with FTIR as well as with 2DIR spectroscopy and discussed. Inter-molecular hydrogen bond making and breaking between N-H and C=O vibrational bands are discussed also.

A series of 17 beta-amide-2-methoxyestradiol compounds were synthesized with an aim to enhance the anti proliferative effect of 2-methoxyestradiol. The antiproliferative activity of 2-methoxyestradiol analogs against human cancer cells was investigated. 2-methoxy-3-benzyloxy-17 beta-chloroacetamide-1,3,5(10)-triene (5e) and 2-methoxy-3-hydroxy-1713-butyramide-1,3,5(10)-triene (6c) had comparable or better antitumor activity than 2-methoxyestradiol. The elimination half-life of 6c (t(1/2 beta) = 240.93 min) is ten times longer than 2-ME and the area under the curve was seven times (AUC(0-tmin) = 2068.20 +/- 315.74 lig mL(-1) min) higher than 2-ME, respectively. Whereas 5e had similar pharmacokinetic behavior with 2-ME (t(1/2 beta) = 22.28 min) with a t(1/2 beta) of 29.5 min. 6c had higher blood concentration, longer actuation duration and better suppression rate against 5180 mouse ascites tumor than 2-methoxyestradiol.
