Solid-liquid equilibria and excess enthalpies in binary mixtures of acetophenone with some aliphatic amides

Solid-liquid equilibria for the binary systems of acetophenone and {N-methylformamide, or N,N-dimethylformamide, or N,N-dimethylacetamide, or N-methyl-2-pyrrolidone} were determined by the cloudpoint and DSC techniques. For the same systems, excess enthalpies were measured at 293.15 K and 308.15 K by the titration calorimetry. Both types of data were correlated by the Redlich-Kister equation. The description of the solid-liquid equilibria incorporated measured excess enthalpies. The results of the prediction performed by the modified UNIFAC model were compared with the experimental data. The observed trends and differences between systems were discussed. (C) 2019 Elsevier B.V. All rights reserved.

Anticancer and apoptotic activity of biologically synthesized zinc oxide nanoparticles against human colon cancer HCT-116 cell line- in vitro study

Aim of this study was to synthesize the safe and stable zinc oxide nanoparticles (ZnONPs) from the leaves of Artocarpus heterophyllus. The alter in the color of the leaf extract dark brown upon addition of zinc nitrate Zn(NO3) confirms the formation of Zinc Oxide nanoparticles (ZnONPs). UV-VIS spectrophotometric analysis showed lambda max at 235 nm while Fourier transform infra-red (FTIR) spectroscopy showed various amines and amides are involved in the stabilization of ZnONPs. Energy dispersive X -rays (EDX) confirms the presence of zinc. Transmission electron microscopy (TEM) analysis revealed particle size ranges from 12 to 24 nm. These observed characteristic of nanoparticles are extremely useful in anticancer activities against HCT-116 colon cancer cell line. These ZnONPs showed IC50 value at 20 mu g/ml while on normal Vero cell line showed less effective by MTT assay. Furthermore, these nanoparticles were evaluated for apoptotic activity by acridine orange/ethidium bromide (AO/EB) double staining method showed the membrane blebbing and chromatin condensation.

Discovery of BMS-986202: A Clinical Tyk2 Inhibitor that Binds to Tyk2 JH2

A search for structurally diversified Tyk2 JH2 ligands from 6 (BMS-986165), a pyridazine carboxamide-derived Tyk2 JH2 ligand as a clinical Tyk2 inhibitor currently in late development for the treatment of psoriasis, began with a survey of six-|membered heteroaryl groups in place of the N-methyl triazolyl moiety in 6. The X-ray co-crystal structure of an early lead (12) revealed a potential new binding pocket. Exploration of the new pocket resulted in two frontrunners for a clinical candidate. The potential hydrogen bonding interaction with ThrS99 in the pocket was achieved with a tertiary amide moiety, confirmed by the X-ray co-crystal structure of 29. When the diversity search was extended to nicotinamides, a single fluorine atom addition was found to significantly enhance the permeability, which directly led to the discovery of 7 (BMS-986202) as a clinical Tyk2 inhibitor that binds to Tyk2 JH2. The preclinical studies of 7, including efficacy studies in mouse models of IL-23-driven acanthosis, anti-CD40-induced colitis, and spontaneous lupus, will also be presented.

A Supramolecular Nanocomposite as a Near-Infrared-Transmitting Optical Filter for Security and Forensic Applications

Visibly opaque but near-infrared (NIR)-transparent materials are an essential component for night-vision photography, security imaging, and forensic applications. Herein, the development of a novel supramolecular black dye from a diketopyrrolopyrrole (DPP)-based low-molecular-weight organogelator is described. In the solution state, the monomer of DPP-Amide exhibits a deep green color with a broad absorption in the visible region due to firm intramolecular charge transfer from the donor to the acceptor unit. Interestingly, due to the synergistic effect of H-bonding and p-stacking, DPP-Amide can form a black organogel in toluene with complete spectral coverage from 300 to 800 nm, and transmits beyond 850 nm. In the gel state, complete visible-spectrum coverage is achieved due to the simultaneous formation of both H-and J-type aggregates, which is confirmed via absorption studies. To create a free-standing NIR-transmitting elastomeric black filter, nanoscopic molecular aggregates of DPP-Amide (0.15 wt%) are embedded into a poly(dimethylsiloxane) matrix. This nanocomposite possesses high NIR transparency with good thermal and photostability for practical applications. Finally, the use of the developed material for NIR photography, security, and forensic-related applications is demonstrated.

N-rich porous organic polymers based on Schiff base reaction for CO2 capture and mercury(II) adsorption

Due to the p-pi conjugative effect between the nitrogen atom of the amide and the carbonyl, the amide carbonyl has much low reactivity and the Schiff base reaction between the amide and amine usually did not take place, but after the amide was polymerized, it’s quite different. Herein, benzene-1,3,5-triyl tris((9H-carbazol-9-yl) methanone) (HTCZ) is not able to have the Schiff base reaction with melamine. Surprisingly, after HTCZ was polymerized according to the Friedel-Crafts reaction, the resultant polymer PHTCZ-1 performed the Schiff base reaction with melamine successfully, and a kind of novel N-rich porous organic polymers, namely, PHTCZ-1-MA was successfully synthesized. Moreover, PHTCZ-1-MA owned much higher Brunauer-Emmett-Teller surface area (613 m(2).g(-1)) and pore volume (0.57 cm(3).g(-1)) with very high nitrogen content (42.39 wt%). The theoretical calculation showed that the positive charge of the carbonyl carbon increased by 18% after the polymerization, which greatly improved the reactivity of the carbonyl. Because of this amazing change, PHTCZ-1-MA was proven to be an excellent adsorbent for CO2 capture (180 mg.g(-1) at 273 K and 1.0 bar) and mercury(II) adsorption (335 mg.g(-1) at 273 K). This study makes the impossibility possible and provides a unique synthesis strategy for the fabrication of a kind of N-rich porous organic polymers. (c) 2020 Elsevier Inc. All rights reserved.

Biocatalytic synthesis of lactones and lactams

Cyclic esters and amides (lactones and lactams) are important active ingredients and polymer building blocks. In recent years, numerous biocatalytic methods for their preparation have been developed including enzymatic and chemoenzymatic Baeyer-Villiger oxidations, oxidative lactonisation of diols, and reductive lactonisation and lactamisation of ketoesters. The current state of the art of these methods is reviewed.

Synthesis, spectral characteristics and microbiological activity of benzanthrone derivatives and their Cu(II) complexes

Two benzanthrone derivatives with an amide group (B1 and B2) attached to the C-3 atom have been synthesized and characterized by different spectral methods. The basic photophysical characteristics were investigated in organic solvents of different polarity. A batochromic shift was observed in the transition from non-polar to polar media. The influence of copper ions on the intensity of fluorescence emission was investigated and a stable copper complex with compound B2 was isolated. Its chemical structure was characterized by electronic spectroscopy, IR and EPR spectroscopy. The stoichiometry of the isolated complex was found to be at a 1: 1 ligand-copper ratio. The microbiological activity of the newly synthesized compounds against gram positive and gram negative bacteria and yeast was examined. The copper complex enhanced the antibacterial activity compared to that of the ligand. (C) 2019 Elsevier B.V. All rights reserved.

Preparation and performance of poly (lactic acid)/fulvic acid benzhydrazide composites

Fulvic acid (FA) was reacted with benzhydrazide to obtain the amide derivative of fulvic acid benzhydrazide (FA-BH). The structure of FA-BH was confirmed by Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. Poly (lactic acid)/fulvic acid benzhydrazide (PLA-FA-BH) composites were prepared by melt blending. Thermogravimetric analysis, differential scanning calorimetry, polarized optical microscopy, and rheological analysis of PLA-FA-BH composites showed that the introduction of 0.1 wt% FA-BH increased the tensile strength, tensile modulus, elongation at break, and impact strength of PLA3 (0.1%) increased by 6.38%, 27.47%, 28.75%, and 74.56%, respectively. The crystallinity of PLA was increased from 4.63% to 41.88% due to FA-BH. The crystallization rate of PLA was greatly improved. The network structure of the PLA matrix became stiff due to incorporation of FA-BH. The storage modulus and complex viscosities of PLA-FA-BH composites were significantly improved compared with pure PLA. The nucleation effect of FA-BH improved the comprehensive performance of PLA.

Synthesis and Antiproliferative Activity of Marine Bromotyrosine Purpurealidin I and Its Derivatives

The first total synthesis of the marine bromotyrosine purpurealidin I (1) using trifluoroacetoxy protection group and its dimethylated analog (29) is reported along with 16 simplified bromotyrosine derivatives lacking the tyramine moiety. Their cytotoxicity was evaluated against the human malignant melanoma cell line (A-375) and normal skin fibroblast cells (Hs27) together with 33 purpurealidin-inspired simplified amides, and the structure-activity relationships were investigated. The synthesized simplified analogs without the tyramine part retained the cytotoxic activity. Purpurealidin I (1) showed no selectivity but its simplified pyridin-2-yl derivative (36) had the best improvement in selectivity (Selectivity index 4.1). This shows that the marine bromotyrosines are promising scaffolds for developing cytotoxic agents and the full understanding of the elements of their SAR and improving the selectivity requires further optimization of simplified bromotyrosine derivatives.
