The search for new fluorescent materials with high quantum yields has been the focus of research, considering the diverse applications that fluorescent materials present. In this study, ferrocenyl pyrazolyl (L1) and ferrocenyl triazolyl (L2) ligands and their palladium metal complexes (1 and 2) were synthesized to investigate their fluorescence properties. While the pyrazolyl ligand was prepared through a ligand substitution reaction, synthesis of the triazolyl derivative involved the [3 + 2] azide-alkyne using click chemistry. All the prepared compounds have been characterized by NMR and IR spectroscopy, elemental analysis, mass spectrometry and single-crystal X-ray crystallography. These air-stable compounds were prepared in moderate to good yields (70% and 83%). The ferrocenyl-pyrazolyl L1 and ferrocenyl-triazolyl L2 ligands showed near-infrared (NIR) emission bands with quantum yields of 20% and 26% respectively. The addition of the Pd2+ ions results in the reduction of fluorescence intensity and quantum yield. Such fluorescent properties demonstrate their potential use in bio-analysis and as fluorogenic probing. (C) 2020 Elsevier B.V. All rights reserved.

The current work investigates the performance of a real-time scan conversion algorithm for generating a 2-D ultrasound image from a laterally scanned single-element ultrasound transducer, which has applications in point-of-care devices such as for skin imaging. The algorithm employs a fixed calibration curve to update a predefined image grid in real time. Simulations showed that the calibration curve (with a maximum of 1) is robust to changes in scatterer concentration (8.3 x 10(-3) mean absolute error), signal to noise ratio (1.0 x 10(-3) mean absolute error for -5 dB SNR), and can be accurately predicted from a small number (31) of point scatterers (6.9 x 10(-3) mean absolute error). Good agreement was also found between the calibration curves obtained from simulated and experimental data (1.19 x 10(-2) mean absolute error). The scan conversion algorithm was validated by evaluation of the position estimation errors on both simulations and experiments. Clinical images of skin lesions (N = 20) demonstrate the feasibility of the algorithm for real, non-homogeneous tissue. Use of a fixed calibration curve compared to an adaptive calibration curve gave similar accuracies in the scanning step size range of 150-350 mu m (with an average overlap of the accuracy ranges of 92.94% for simulations and 42.83% for experiments), and a 350-fold improvement in computation time.

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.

Some new compounds, 2-(3,5-dimethyl-1H-pyrazol-1-yl)-4-substituted acetophenone oximes [4a-4f; here, 4-substituent = H (a), Br (b), Me (c), Cl(d), NO2 (e), F (f)] were synthesized by the reaction of 2-(3,5-d imethyl-1H-pyrazol-1 -yl)-1 -arylethano nes with hydroxylamine hydrochloride. These compounds were characterized by analyzing their IR, H-1, C-13 NMR and mass spectral data. Compounds 4a-4f were further converted into their silver complexes (4g-4l) and chemical structures of which were established on the basis of their X-ray crystallographic data. The antibacterial and DNA photocleavage activity studies were carried out for all the synthesized compounds 4a-4l, and it has been found that compound 4l displayed an excellent level of antibacterial and DNA photocleavage activity. Among the series, Ag-complexes (4g-4l) displayed excellent antibacterial activity against four bacterial strains using Ciprofloxacin as a standard drug. In DNA photocleavage study, it has been observed that compounds 4a, 4e, 4f degraded both forms of DNA, whereas their Ag-complexes degraded DNA completely even at a very low concentration. The intermolecular interactions present in 4g and 4h were described by decomposing Hirshfeld surfaces into 2D fingerprint plots. It was observed that non-polar interactions contribute dominantly in overall intermolecular interactions exit in crystals of both the compounds. (C) 2020 Elsevier Ltd. All rights reserved.

A metal-free promoted direct oxidative C-N bond coupling of quinoxalinones and azoles for the rapid and effective synthesis of potent pharmaceutical important 3-(azol-1-yl)quinoxalin-2-one has been developed. Employing PIDA as the easily available mediator, the desired coupling products were isolated in moderate to excellent yields with a good substrate scope under operational simplicity and mild reaction conditions. Preliminary mechanistic studies suggested that a radical process is likely to be involved in the reaction. (C) 2020 Elsevier Ltd. All rights reserved.

Two coordination complexes of Cu(II) and Co(II) involving 3,5-dimethylpyrazole viz. { [Cu(mu-O,O’-SO4) (Hdmpz)(2)(H2O)]center dot 2H(2)O}(n) (1) and [Co(Hdmpz)(4)(H2O)(2)Cl-2 (2) (where Hdmpz = 3,5-dimethylpyrazole) have been synthesized in purely aqueous medium at room temperature. Crystal structure of complex 1 consists of a polymeric chain of distorted square pyramidal Cu(II) centers bridged by bidentate sulfato ligands. The polymeric chain in 1 has been stabilized by N-H center dot center dot center dot O and C-H center dot center dot center dot pi interactions. Particularly relevant is the polymeric chain in 1, since in addition to the afore mentioned non-covalent contacts, unprecedented chalcogen bonding interactions involving the sigma-hole at the tetrahedral sulfur atom are observed and characterized using theoretical calculations. To our knowledge, sigma-hole chalcogen bonding interactions involving tetrahedral sulfur atom have not been previously reported in the literature. The lattice water molecules self assembles the polymeric chains of 1 into a 3D supramolecular architecture via C-H center dot center dot center dot O hydrogen bonding interactions. The cationic units in the crystal structure of 2 self assembles via O-H center dot center dot center dot Cl, N-H center dot center dot center dot Cl and C-H center dot center dot center dot Cl weak hydrogen bonding interactions into a 2D supramolecular architecture induced by chloride anions in the lattice. PXRD patterns of 1 and 2 demonstrate good phase purity of the complexes. In addition, the thermal behaviour of the complexes has also been investigated.
