A new semi-theoretical equation is suggested for correlation of solid-liquid solubility data with temperature. The (solid + liquid) equilibrium for Terephthaldialdehyde, 4-Nitro-o-phennylenediamine, 2,4-dihydro- 5-methyl-2(4-methylphenyl)-3H-pyrazol-3-one (also named 1-(p-toly1)-3-methyl-5pyrazolone (PTMP)), 2-Amino-5-methylthiazole and 5-chloro-1-methyl-4-nitroimidazole in 18 solvents is correlated with semi-empirical models at temperatures T = 273.15 – 318.15 K under a pressure of 101.2 kPa. Moreover, a modified Apelblat model, lambda h model, Wilson model, NRTL model, new flexible equation as Akbari, Dideban and Farhang model (ADF) and for first time the modified Scatchard-Hildebrand equation were utilized to calculate the experiment values. The performance of both ADF and modified Scatchard-Hildebrand equation have been checked by calculating the solubility data with the AARD% of 1.3808% (for 775 data points) and 0.65% (for 100 data points), respectively. The Wilson model is applied to estimate the mixing Gibbs energy, mixing enthalpy, mixing entropy, activity coefficient (ln gamma(infinity)(1)) and reduced excess enthalpy (H-I(E,infinity)) at infinitesimal concentration were calculated.

A novel bispyrazole-based expanded cryptand was synthesized via Schiff base condensation reaction having an internal cavity of 160 angstrom(3) with a hydrophobic nature. The cryptand features electron-rich multiple pyrazole rings for enhanced weak noncovalent interactions with the guest molecules. The host-guest capabilities of the cryptand were investigated for encapsulation of the most inactive halogen bond donor molecules (having small sigma-hole size), namely, CH2Cl2, CHCl3, CCl4, C2HCl3, C2H4Cl2, and C2H4Br2. Analysis of crystal structures clearly revealed that halogen bonding (C-Cl/Br center dot center dot center dot pi (pyrazole)) and hydrogen bonding (C-H center dot center dot center dot pi(pyrazole)) interactions played a key role in stabilizing the halogenated guests inside the hydrophobic cavity of cryptand. At the same time, the cage is efficiently able to exclude hydrophilic solvent molecules, like, water and methanol, suggesting the hydrophobic nature of the cavity. Due to the comparably large sigma-hole in C2H4Br2, it showed the strongest halogen bonding interaction with the host cryptand, while weakest interaction was found for the CH2Cl2 guest which has the smallest size sigma-hole. Furthermore, the cryptand is able to adjust its central cavity according to the size of the guest. The biggest cavity size was found for the C2H4Br2 guest, while smallest size was found for the CH2Cl2 guest molecule. This study sheds more light on the interaction of halogenated solvents via halogen and hydrogen bonding, which is critical in understanding and controlling chemical reactions where solvent effects play an important role.

Two new Ni(II) coordination complexes of pyrazole and acetato ligands, involving nitrate and chloride counter anions, viz. [Ni(Hdmpz)(2)(CH3COO)(H2O)(3)]NO3 center dot 2H(2)O (1) and [Ni(Hdmpz)(2)(CH3COO)(H2O)(3)]Cl (2) (where Hdmpz = 3,5-dimethylpyrazole), have been synthesized in purely aqueous medium at room temperature. The complexes have been characterized by elemental analysis, FT-IR, electronic spectroscopy, PXRD, TGA and single crystal X-ray diffraction. The H-bonds established between the isostructural cationic [Ni(Hdmpz)(2)(CH3COO)(H2O)(3)](+) moieties of both complexes can be classified as anti-electrostatic H-bonds (AEHBs) and these have been studied using DFT calculations. Remarkably, in one case these AEHBs exhibit favorable interaction energies, thus indicating that the attractive nature of the H-bonds is able to compensate the pure electrostatic repulsion. The analyses of the cell viability results for the DL cell line show a significant concentration dependent decrease by compounds 1 and 2 with a negligible cytotoxic effect observed against normal cells (PBMC) in comparison to the cancer cells (DL). The cytotoxic activity of these compounds in DL cells occurs via apoptosis. Molecular docking and SAR analysis reveal that the compounds possess high binding affinities against most common cancer target proteins. (C) 2019 Elsevier Ltd. All rights reserved.

Purpose: Regorafenib is an oral multikinase inhibitor approved for the therapy of previously treated metastatic colorectal carcinoma (mCRC). The aim of the present study was to analyze the outcomes of treatment with regorafenib in real-world clinical practice based on data from a national registry. Methods: The CORECT registry, the Czech non-interventional database of patients with mCRC treated with targeted agents, searched for patients with metastatic CRC treated with regorafenib. In total, 555 evaluable patients were identified. Results: The median age at diagnosis was 61.7 years. All patients had disease progression on or after previous systemic treatment. Most patients were treated with an initial dose of 160 mg daily (n = 463; 83.6%). The median duration of treatment was 2.7 months (range 0.023.4 months). By the data cut-off date, 472 patients (85%) had completed treatment with regorafenib and were evaluable for treatment response evaluation. Partial response was reported in 13 patients (2.8%) and disease stabilization in 130 patients (27.5%). Median progression-free survival (PFS) and overall survival (OS) were 3.5 months (95% confidence interval [CI] 3.2-3.7 months) and 9.3 months (95% CI 8.3-10.3 months), respectively. The 6-month OS rate was 67.7% (95% CI 63.4-72.1%). Multivariable analysis showed that female gender, longer interval from diagnosis of metastatic disease, MO stage at diagnosis, and Eastern Cooperative Oncology Group performance status (ECOG PS) 0 were associated with longer PFS, while higher body-mass index (BMI), longer interval from diagnosis of metastatic disease, and ECOG PS of 0 were associated with longer OS. Conclusion: OS of patients treated with regorafenib in the real-world clinical practice in this cohort exceeded that reported in randomized trials. Regorafenib is a safe and active treatment option for a subgroup of patients with mCRC who are progressing after other systemic therapies and maintain good performance status.

The first Pd-catalyzed asymmetric allenylic [4+1] cycloaddition was successfully developed. Alternatively, tuning the Pd catalyst switched the reactivity toward an unprecedented [4+3] cycloaddition/cross-coupling. Ligands play a vital role in controlling the reaction pathway, allowing highly selective access to different products from identical substrates. Biological evaluation of the obtained compounds led to the discovery of new antitumor targets. A possible mechanism is proposed, suggesting two interesting catalytic cycles for the cycloaddition with palladium-butadienyls. This study also demonstrated the potential and utility of allenic esters as 1,4-biselectrophiles and C-4 synthons for participating in cycloaddition reactions.

Self-healing materials can partially or completely heal the damage done to them, and it is expected that their original function will be thereby restored. Herein, we report a novel self-healing polyvinyl (Sh-PV) containing functional polymer that reacts to thermal and ultraviolet (UV) energy. The structure of Sh-PV was characterized by fourier transform infrared spectroscopy (FTIR) and nuclear magnetic resonance spectroscopy (H-1 NMR). In addition, aluminum oxide (Al2O3) inorganic nanoparticles (NPs) were added and hybridized to improve their poor self-healing efficiency and surface hardness of the coated thin film. Mechanical nanoscratch testing and scanning probe microscopy (SPM) imaging of surface using a nanoindenter were performed to investigate the healing ability of self-healing thin films. The organic-inorganic hybrid self-healing polymer thin film exhibited a 10 % improvement in surface hardness as well as 100 % healing against nanoscale damage compared to virgin self-healing polymers. Here, we discuss and evaluate the optimized method and mechanism of the self-healing system based on the results of self-healing materials and physical recovery methods for healing surface damage.

The Pd(ii)-catalyzed activation of Csp(2)-H bond and double alkyne annulation which proceeds via allylic isomerization is reported for the first time. This reaction of antipyrines with alkynes provides an efficient synthetic route for the biologically important spiro-cyclopentadiene pyrazolones. In the presence of Lawesson’s reagent, this Pd(ii)-catalyzed annulation reaction affords another spiro-cyclopentadiene pyrazolone which displays very good fluorescence properties.

Here in, the effects of FeSiAl particle size on the dielectric and microwave absorption properties of FeSiAl/Al2O3 composites were studied. FeSiAl/Al2O3 composites containing 18-25 mu m, 25-48 mu m, and 48-75 mu m FeSiAl particles were prepared by hot-pressed sintering based on uniformly mixed FeSiAl and Al2O3 powders. Results show that the real permittivity and the imaginary permittivity are significantly promoted with increasing FeSiAl particle size, which is ascribed to the enhanced interfacial polarization and conductance loss. In addition, the favorable matching impedance and suitable attenuation coefficient enabled the composite containing 25-48 mu m FeSiAl powder to show a minimum reflection loss of -34.4 dB at 11.7 GHz and an effective absorption bandwidth (<-10 dB) of 1.4 GHz in 11.0-12.4 GHz, when the thickness is 1.1 mm. By adjusting the thickness to 1.4 mm, the effective absorption bandwidth of the composite reaches a maximum value of 2.0 GHz in the 8.3-10.3 GHz range, indicating tunable, strong, and highly efficient microwave absorption performance.
