Data for the homology modelling of the red pigment-concentrating hormone receptor (Dappu-RPCHR) of the crustacean Daphnia pulex, and docking of its cognate agonist (Dappu-RPCH)

The data presented in this article are related to the publication Interaction of the red pigment-concentrating hormone of the crustacean Daphnia pulex, with its cognate receptor, Dappu-RPCHR: A nuclear magnetic resonance and modeling study (Jackson et al., 2017) [1]. This article contains the data for homology modeling of the red pigment-concentrating hormone (RPCH) receptor of the water flea, Daphnia pulex (Dappu-RPCHR), which was constructed from its primary sequence. This is the first 3D model of a crustacean G-protein coupled receptor. Docking of the agonist, pGlu-Val-Asn-Phe-Ser-Thr-Ser-Trp amide (Dappu-RPCH), was used to find a binding pocket on the receptor and compared to the binding pocket of the adipokinetic hormone (AKH) receptor from the malaria mosquito. Data for the receptor, with and without loop refinement, together with the docked agonist, are presented. (C) 2017 The Authors. Published by Elsevier Inc.

Amino Acid- and Growth Factor-Based Multifunctional Nanocapsules for the Modulation of the Local Microenvironment in Tissue Engineering

Oxidative damage to cells from metabolites at a wound site is one of the trickiest factors inhibiting tissue regeneration, especially with bulk damage. In addition, an excessive inflammatory reaction by the body at the wound site can make it even worse. How to scavenge the reactive oxygen species (ROS) produced from metabolism and inflammatory reactions has become a critical issue in tissue engineering. Here, we utilize the natural bioactive small molecules L-arginine and L-phenylalanine and the growth factor inositol to synthesize a branched poly(ester amide) (BPEA) to fabricate BPEA nanocapsules for vitamin E delivery at wound sites. BPEA nanocapsules loaded with vitamin E (BPEA@VE NCs) could protect cells from both extracellular and intracellular damage by scavenging ROS. Simultaneously, the inflammatory reaction could also be downregulated, benefiting from the introduction of L-arginine. Furthermore, the biodegradation products of BPEA are natural metabolites of the body, such as amino acids and growth factors, guaranteeing the biocompatibility of the BPEA@VE NCs. The protective ability of the BPEA@VE NCs was also investigated in vivo for accelerated wound healing. All the results indicate that the BPEA@VE NCs have promising potential for the modulation of the local microenvironment in tissue engineering for excellent antioxidative and anti-inflammatory properties.

Zirconium-based conversion film formation on zinc, aluminium and magnesium oxides and their interactions with functionalized molecules

Zirconium-based conversion treatment of zinc, aluminium and magnesium oxides have been studied in-situ using ATR-FTIR in a Kretschmann geometry. This set-up was coupled to an electrochemical cell, which allowed to obtain chemical and electrochemical information simultaneously as a function of conversion time. This elucidated the strong relation between physico-chemical surface properties and zirconium-based conversion kinetics. Whereas the surface hydroxyl density of zinc and aluminium increased during conversion, magnesium (hydr) oxide was shown to dissolve in the acid solution. Due to this dissolution, strong surface alkalization can be expected, explaining the rapid conversion kinetics. AES depth profiling was used to determine the final oxide thickness and elemental composition. This confirmed that magnesium is most active and forms a zirconium oxide layer approximately 10 times thicker than zinc. On the other hand, the presence of zirconium oxide on aluminium is very low and can be considered as not fully covering the metal oxide. Additionally, the converted oxide chemistry was related to the bonding mechanisms of amide functionalized molecules using ATR-FTIR and XPS. It was shown that inclusion of zirconium altered the acid-base properties, increasing the substrate proton donating capabilities in case of magnesium oxide and increasing hydrogen bonding and Bronsted interactions due to increased surface hydroxide fractions on zinc and aluminium substrates.

Synthesis of sigma Receptor Ligands with a Spirocyclic System Connected with a Tetrahydroisoquinoline Moiety via Different Linkers

With the aim to develop new sigma(2) receptor ligands, spirocyclic piperidines or cyclohexanamines with 2-benzopyran and 2-benzofuran scaffolds were connected to the 6,7-dimethoxy-1,2,3,4-tetrahydroisoquinoline moiety by variable linkers. In addition to flexible alkyl chains, linkers containing an amide as functional group were synthesized. The 2-benzopyran and 2-benzofuran scaffold of the spirocyclic compounds were synthesized from 2-bromobenzaldehyde. The amide linkers were constructed by acylation of amines with chloroacetyl chloride and subsequent nucleophilic substitution, the alkyl linkers were obtained by LiAlH4 reduction of the corresponding amides. For the development of sigma(2) receptor ligands, the spirocyclic 2-benzopyran scaffold is more favorable than the ring-contracted 2-benzofuran system. Compounds bearing an alkyl chain as linker generally show higher sigma affinity than acyl linkers containing an amide as functional group. A higher sigma(1) affinity for the cis-configured cyclohexanamines than for the trans-configured derivatives was found. The highest sigma(2) affinity was observed for cis-configured spiro[[2]benzopyran-1,1 ‘-cyclohexan]-4 ‘-amine connected to the tetrahydroisoquinoline system by an ethylene spacer (cis-31, K-i (sigma(2))=200 nM; the highest sigma(1) affinity was recorded for the corresponding 2-benzofuran derivative with a CH2C=O linker (cis-29, K-i (sigma(1))=129 nM).

CuO-catalyzed conversion of arylacetic acids into aromatic nitriles with K4Fe(CN)(6) as the nitrogen source

Readily available CuO was demonstrated to be effective as the catalyst for the conversion of arylacetic acids to aromatic nitriles with non-toxic and inexpensive K4Fe(CN)(6) as the nitrogen source via the complete cleavage of the C N triple bond. The present method allowed a series of arylacetic acids including phenylacetic acids, naphthaleneacetic acids, 2-thiopheneacetic acid and 2-furanacetic acid to be converted into the targeted products in low to high yields.

How Promoting and Breaking Intersurfactant H-Bonds Impact Foam Stability

On the basis of previous results revealing that intersurfactant H-bonds improve foam stability, we now focus on how foams stabilized by two different N-acyl amino acid surfactants are affected by different salts (NaF, NaCl, NaSCN), which can promote or break intersurfactant H-bonds. The chosen surfactants, namely, sodium N-lauroyl sarcosinate (C(12)SarcNa) and sodium N-lauroyl glycinate (C(12)GlyNa), differ only by one methyl group at the nitrogen of the amide bond that blocks intersurfactant H-bonds in the case of C(12)SarcNa. The salts were chosen because they are kosmotropic (NaF), chaotropic (NaSCN), and in between (NaCl) and thus influence the formation of an H-bond network in different ways. Surface tension measurements showed that the addition of salts decreased the cmcs of both surfactants and increased the packing density, as expected. Moreover, in presence of the salts, the head groups of the H-bond forming surfactant C(12)GlyNa were more tightly packed at the surface than the C(12)SarcNa head groups. The effect of the salts on foam stability was studied by analysis of the foam height, the foam liquid fraction, and by image analysis of the foam structure. As expected, the salts had no significant effect on foams stabilized by C(12)SarcNa, which is unable to form intersurfactant H-bonds. In contrast, the stability of C(12)GlyNa-containing foams followed the trend NaF > NaCl > NaSCN, which is in agreement with NaF promoting and NaSCN breaking intersurfactant H-bonds. Surface rheology measurements allowed us to correlate foam stability with surface elasticity. This study provides new insights into the importance of H-bond promoters and breakers, which should be used in the future design of tailor-made surfactants.

Non-amide based zwitterionic poly(sulfobetaine methacrylate)s as kinetic hydrate inhibitors

Applying kinetic hydrate inhibitors (KHIs) to avoid the pipeline blockage caused by hydrate formation in gas and oil industry is a comparatively effective and cost-saving method. The main ingredients in most KHIs are water-soluble polymers containing repeating amide group units, placed structurally close to hydrophobic groups. In this report we have synthesized a class of non-amide polymers, zwitterionic poly(sulfobetaine methacrylate)s, and investigated them as KHIs for the first time. Results show that the best zwitterionic polymers have good KHI efficacy with the key performance parameter being the length of the alkyl chain on the monomer unit side chains. Copolymer of the zwitterionic monomers and N-isopropylmethacrylamide (NIPMAM) gave much better increase in KHI performance with increas-ing concentration than the zwitterionic homopolymers. This result together with other related studies suggests that strong hydrogen-bonding groups like amide or amine oxide groups are important for high KHI performance. Reasons for this are discussed.

Total Synthesis of Divergolides E and H

This manuscript describes the first total syntheses of divergolides E and H. The route employs a telescoped hetero-Diels-Alder and oxidative carbon-hydrogen bond cleavage as an entry into the central bridged bicyclic acetal unit. Additional key steps of the highly convergent route include a desymmetrizing epoxidation, a chelation-controlled alkenylzinc addition, an amide formation between a hindered aniline and an acylating agent that is prone to ketene formation, and a challenging macrolactonization.

Coadministration of chemotherapy and PI3K/Akt pathway treatment with multistage acidity/CathB enzyme-responsive nanocarriers for inhibiting the metastasis of breast cancer

As the principal reason for the inducement of high mortality, tumor metastasis is regulated by different pathways owing to its complexity and multistep process. In order to inhibit the proliferation and metastasis of human breast cancer simultaneously, controlling the codelivery of chemotherapeutics and pathway inhibitors precisely has been considered as a high-potential strategy to accurately eliminate tumor metastasis. In this study, polymer PLGA-p-PEI-DA was synthesised and automatically assembled into a cascade trinity response drug delivery system, i.e., PPP-DA/NPs (PLGA: poly(lactin-co-glycolic acid), PEI: polyethyleneimine, DA: 2,3-dimethylmaleic anhydride). In the tumor microenvironment, PPP-DA/NPs could remove the outer DA molecules via the pH-sensitive hydrolysis of beta-carboxylic amide bonded with DA and PEI. Then, PPP-DA/NPs were broken up owing to the enzymatically cleavable GFLGF (Gly-Phe-Leu-Gly-Phe) linker. The structure of the polymer and the properties of PPP-DA/NPs were evaluated in detail. Moreover, studies on the antitumor metastasis efficiency and antitumor mechanism of PPP-DA/NPs were carried out in detail. As demonstrated in this study, PPP-DA/NPs could reverse the potential in pH 6.8 PBS and showed elevated cellular uptake efficiency. Moreover, PPP-DA/NPs exhibited strong antitumor metastasis ability in vitro and in vivo. The tumor inhibiting rate (TIR) of PPP-DA/NPs (68.4%) was significantly higher than that of docetaxel (DTX) (5.9%). The antitumor mechanistic studies confirmed that PPP-DA/NPs could down-regulate the expressions of Akt, MMP-9 and pro-caspase-3/9 protein, as indicated by western blot analysis. This multifunctional drug delivery system (DDS) is highly selective and effective in inhibiting tumor metastasis, which shows a great potential in inventing smart nanocarriers for targeted tumor-metastasis therapy.

N-Acyl Amino Acids: Metabolism, Molecular Targets, and Role in Biological Processes

The lipid signal is becoming increasingly crowded as increasingly fatty acid amide derivatives are being identified and considered relevant therapeutic targets. The identification of N-arachidonoyl-ethanolamine as endogenous ligand of cannabinoid type-1 and type-2 receptors as well as the development of different-omics technologies have the merit to have led to the discovery of a huge number of naturally occurring N-acyl-amines. Among those mediators, N-acyl amino acids, chemically related to the endocannabinoids and belonging to the complex lipid signaling system now known as endocannabinoidome, have been rapidly growing for their therapeutic potential. Here, we review the current knowledge of the mechanisms for the biosynthesis and inactivation of the N-acyl amino acids, as well as the various molecular targets for some of the N-acyl amino acids described so far.
