Calixarenes, with potential functionalization on the upper and lower rim, have been explored in recent years for the design and construction of anticancer agents in the field of drugs and pharmaceuticals. Herein, optimization of bis [N-(2-hydroxyethyl) aminocarbonylmethoxyl substituted calix [4] arene (CLX-4) using structure-based drug design and traditional medicinal chemistry led to the discovery of series of calix [4]arene carbonyl amide derivatives 5a-5t. Evaluation of the cytotoxicity of 5a-5t employing MTT assay in MCF-7, MDA-MB-231 (human breast cancer cells), HT29 (human colon carcinoma cells), HepG2 (human hepatocellular carcinoma cells), A549 (human lung adenocarcinoma cells) and HUVEC (Human Umbilical Vein Endothelial) cells demonstrated that the most promising compound 5h displayed the most superior inhibitory effect against A549 and MDA-MB-231 cells, which were 3.2 times and 6.8 times of CLX-4, respectively. In addition, the cell inhibition rate (at 10 mu M) against normal HUVEC cells in vitro was only 9.6%, indicating the safty of compound 5h. Moreover, compound 5h could inhibit the migration of MDA-MB-231 cell in wound healing assay. Further mechanism studies significantly indicated that compound 5h could block MDA-MB-231 cell cycle arrest in G0/G1 phase by down regulating cyclin D1 and CDK4, and induce apoptosis by up-regulation of Bax, down-regulation of Caspase-3, PARP and Bcl-2 proteins, resulting in the reduction of DNA synthesis and cell division arrest. This work provides worthy of further exploration for the promising calixarene-based anticancer drugs. (C) 2020 Elsevier Masson SAS. All rights reserved.

The efficient and reproducible production of nanoparticles using bulk nanoprecipitation methods is still challenging because of low batch to batch reproducibility. Here, we optimize a bulk nanoprecipitation method using design of experiments and translate to a microfluidic device to formulate surface-modified poly-lactic-co-glycolic (PLGA) nanoparticles. Cell-penetrating peptides (CPPs) with a short, long linear or branched architecture were used for the surface modification of PLGA nanoparticles. The microfluidics method was more time efficient than the bulk nanoprecipitation method and allowed the formulation of uniform PLGA nanoparticles with a size of 150 nm, a polydispersity index below 0.150 and with better reproducibility in comparison to the bulk nanoprecipitation method. After surface modification the size of CPP-tagged PLGA nanoparticles increased to 160-180 nm and the surface charge of the CPP-tagged PLGA nanoparticles varied between -24 mV and +3 mV, depending on the architecture and concentration of the conjugated CPP. Covalent attachment of CPPs to the PLGA polymer was confirmed with FTIR by identifying the formation of an amide bond. The conjugation efficiency of CPPs to the polymeric PLGA nanoparticles was between 32 and 80%. The development and design of reproducible nanoformulations with tuneable surface properties is crucial to understand interactions at the nano-bio interface.

The present work aims to develop a class of green demulsifiers for effective demulsification process. In this respect, six chitosan-based nonionic surfactants were prepared by chemical modification of chitosan with two aliphatic fatty acids, namely, lauric and stearic. The products were then reacted with polyethylene glycol (PEG 400, 1000 and 2000 g/mol) to produce ether amides surfactants. The prepared surfactants were characterized by IR spectroscopy and their thermal properties were investigated. It was found that the thermal stability of the prepared surfactants increase by increasing the length of PEG chain. Surface properties of the prepared surfactants were calculated through surface tension measurements at different temperatures. Furthermore, the demulsification efficiency of the prepared surfactants was verified under different conditions. Also, maximum water separation was achieved at 45 degrees C, neutral medium and low salt concentration. Viscosity of crude oil before and after demulsification was used as a parameter for demulsification process. Moreover, the demulsification process achieved by the green demulsifiers was monitored by the optical microscope. (C) 2018 Elsevier B.V. All rights reserved.

The bio-crude oil produced from hydrothermal liquefaction (HTL) of a high-protein microalgae useful for wastewater treatment, Galdieria sulphuraria, was comprehensively characterized, and compared to that of a high lipid microalgae useful for biofuel production, Nannochloropsis sauna. HTL was conducted in a batch reactor at temperatures of 310-350 degrees C and reaction times of 5-60 min. Characterization methods included high-resolution Fourier transform ion cyclotron resonance mass spectroscopy (FT-ICR MS), fatty add methyl ester (FAME) analysis by gas chromatography mass spectroscopy (GC/MS), proton nuclear magnetic resonance spectroscopy (H-1 NMR), and Fourier transform infrared spectroscopy (FT-IR). Milder reaction conditions favored bio-crude oil yield and quality for N. sauna, while more severe conditions (350 degrees C) were needed for G. sulphuraria. N. salinaderived bio-crude oil contained mainly C-14-C-18 fatty acid amides, while G. sulphuraria-derived bio-crude-oil had many N1-3O0-2 hetero-atom compounds. FT-ICR MS showed that the aromaticity of hetero-compounds in N. sauna bio-crude oil was higher due to N. sauna’s higher carbohydrate content and the tendency of carbohydrate derived molecules to condense at HTL conditions. FAME-GC/MS and H-1-NMR results showed that stable fatty acid amides increased in G. suiphuraria bio-crude oil at higher temperatures as more protein-derived compounds combined with lipid-derived compounds. While N-containing and high molecular weight compounds are a concern for the upgrading of bio-crude oils obtained from high-protein algal biomass, removal of carbohydrates rather than removal of proteins as a pretreatment to HTL is recommended since carbohydrate-derived compounds are more likely to create highly aromatic hetero-compounds that are much more difficult to upgrade.

An efficient strategy to modulate the mechanical properties of conjugated polymers has been developed through the incorporation of amide-containing alkyl chains in diketopyrrolopyrrole-based conjugated polymers. The side-chain engineering performed with hydrogen bonding moieties (up to 20 mol% of amide-containing side-chains) was found to reduce the crystallinity of the conjugated polymers in the solid state. Interestingly, this reduction in crystallinity drastically influenced the mechanical properties of the new DPP-polymers, by promoting their stretching ability, reducing the elastic modulus of the polymers, and facilitating the molecular alignment after stretch. The resulting polymers with 10% hydrogen bonding side chains showed a maximum stretchability of 75% elongation, without the appearance of nanoscale cracks, and a detailed investigation of the mechanical properties was performed by a combination of morphological characterization tools, including grazing-incidence X-ray diffraction, polarized UV-Vis spectroscopy and optical/atomic force microscopy to support our finding. Additionally, incorporation of amide-containing side-chains also enabled the regeneration of the conjugated polymer morphology after damage. Our results demonstrate that the introduction of amide-containing alkyl chains is an effective strategy to enhance the mechanical properties of -conjugated polymers without disrupting the -conjugation, and to enable new properties such as morphological healing.

The specific interactions between polyacrylamide brushes composed of polyacrylamide chains tethered to montmorillonite particles (Mt-g-PAm) and the individual components of immiscible ethylene-propylene-diene modified with sorbic acid (EPDM) and methyl vinyl silicone (MVQ) blends were studied. The effect of various lengths of PAm chains and their grafting density on montmorillonite (Mt) surface was investigated. It was determined that, due to interactions generated within the system through carboxyl and amide groups the brush particles were selectively located at the EPDM/MVQ interphase and in the EPDM phase. Furthermore, the longer PAm chains resulted in an increase of the glass transition of EPDM, unification of blend morphology, and the reduction of crystallinity of the MVQ phase. Therefore, precisely designed polymer brushes could be considered as novel functional compatibilizers, that provide a new tool for the future material designing.
