2, 3-Dihydroquinazolinones are of popular compounds with the diversification of biological and pharmacological activities. Among many discovered methods, there are efficient and convenient methods used for the synthesis of 2, 3-dihydroquinazoline-4 (1H)-one and some new bis 2, 3-dihydroquinazoline-4 (1H)-one derivatives which are reported in this study. The mentioned methods include the two-component condensation of one molecule of anthranilamide and one molecule of pyrazole carbaldehyde using montmorillonite-K 10 as a catalyst for the preparation of 2, 3 dihydroquinazoline-4 (1H)-ones. Also, one-pot pseudo-five-component reaction (5MCRs) of two molecules of isatoic anhydride, two molecules of pyrazole carbaldehydes and one molecule of ethan-1, 2-diamine in the presence of the r catalyst (montmorillonite-K10) for the synthesis of bis 2, 3-dihydroquinazoline-4 (1H)-ones. Despite the short times of reactions, high yields of products were obtained, which were validated using FT-IR, (HNMR)-H-1, (CNMR)-C-13, and elemental analysis. Moreover, the compounds were screened for their antimicrobial activities against two-gram-positive bacterial strains: Staphylococcus aureus and Micrococcus Luteus; and against two-gram-negative bacterial strains, as well: Escherichia coli and Pseudomonas aeruginosa, which all were utilized for antibacterial investigations. The results showed moderate or significant antibacterial activities.

Modified graphite oxide (NGO) was used as a support of a manganese oxide of hausmannite type (Mn3O4) nanocatalyst and applied for the degradation of an endocrine disruptor, bisphenol-A (BPA). The prepared nanocomposite/catalyst (NGO-Mn3O4), as well as pure modified graphite oxide and manganese oxide, were characterized by X-ray diffraction, Scanning Electron Microscopy, nitrogen adsorption, X-ray photoelectron spectroscopy, Fourier Transform Infrared Spectroscopy, and potentiometric titration. The maximum removal activity for all the materials was measured at pH = 3. The NGO-Mn3O4 nanocomposite showed the highest removal efficiency of BPA at an ambient temperature without light irradiation and/or the addition of chemicals, which can be attributed to the synergistic effect of the composite formation. The nanocomposite exhibited a high catalytic activity for the degradation/oxidation of BPA, which was dramatically higher than that of the pristine Mn3O4 phase. Modified graphite oxide showed also an enhanced capability for the BPA removal, which was linked to an increased physical adsorption component. (C) 2018 Elsevier Inc. All rights reserved.

Gallic acid is abundantly found in amla (Phyllanthus emblica), a deciduous of the family phyllanthaceae. Gallic acid, the major constituent of the plant, was methylated to 3,4,5 trimetboxy gallic acid, which then underwent steglich esterification first with paracetamol and then with 4-hydroxy acetophenone to yield 4-acetamidophenyl 3,4,5-trimethoxybenzoate and 4-acetyl phenyl 3,4,5-trimethoxybenzoate respectively. 1H NMR, 13C NMR, UV, FT-IR and mass spectroscopy were used to characterize the synthesized compounds. Density functional theory (B3YLP) using a 6-31G (d,p) basis set has been used for quantum chemical calculations. AIM (Atom in a molecule) approach depicted weak molecular interactions within the molecules, whereas the reactive site and reactivity within the molecule were examined by global and local reactivity descriptors. The HOMO and LUMO energies and frontier orbital energy gaps were calculated by time dependent DFT approach using the IEFPCM model. A small value for the HOMO-LUMO energy gap indicated that easier charge transfer occurs within compound 4. The nucleophilic and electrophilic reactivity was determined by MEP (molecular electrostatic potential) experiment. Polarizability, dipole moment, and first hyperpolarizability values were calculated to depict the NLO (nonlinear optical) property of both the synthesized compounds. The antimicrobial activity was also carried out and broad-spectrum antibacterial activity against several strains of bacteria and certain unicellular fungi were exhibited by synthesized compound 3.

Several small molecules targeting microtubule dynamics have been developed because microtubules are considered to be one of the most successful cancer chemotherapeutic targets. In this regard, taxol is most worthy to mention which stabilizes microtubule polymer thereby causing defectsinmitotic spindle assembly, chromosome segregation and cell division resulting in cancer inhibition. In this direction, we have earlier reported a small molecule called Pyrimidine-Indole-Hybrid (PIH (P)) which was found to inhibit ciliogenesis by inhibiting both the acetylation and polymerization of tubulin subunits. Here, we have evaluated the anticancer activities of PIH (P) and its water soluble derivatives. Three water soluble derivatives of PIH (P) namely 6 A, 6B and 6 C were synthesized. Among PIH (P) series of compounds, PIH (P) and 6 C were found to be the most potent compounds showing anti-proliferative and cytoskeletal disrupting activities against MCF-7 cells. Not only that, PIH (P) and 6 C also showed a promising effect in preventing cancer cell migration, invasion and colony-formation and helped to reduce spheroid formation by several-folds. They have potential to inhibit the activity of proteins (N-Cadherin, Vimentin) responsible for Epithelial to Mesenchymal Transition (EMT). Hence, this class of compound could be a new antimitotic agent that is different from taxol with respect to mechanism, particularly by destabilizing tubulin rather than causing stabilization.

A large number (63) of well-defined nitroxide radicals, all phenol-based TEMPO and PROXYL esters, were synthesized using different strategies based on well-established Steglich esterifications. All of these radicals can be used as spin probes (SPs) and spin labels (SLs) for electron paramagnetic resonance (EPR) spectroscopy of supramolecular systems. Depending on the nature of the functional group(s) on each SP/SL, the synthesized nitroxide radicals serve as polyphilic molecular toolbox for the EPR-spectroscopic detection and characterization of specific types of interactions, e. g. pi-pi interactions, sulfur-sulfur interactions, hydrogen bonding, electrostatic and dipole-dipole interactions, and van der Waals and hydrophobic interactions, in the presence of the selected supramolecular systems of interest (e. g. proteins, peptides). For each synthesized SP/SL the water solubility was gravimetrically determined for use in aqueous solution at pH 7.

Liver cancer is a kind of high mortality cancer due to the difficulty of early diagnosis. It is necessary to develop the anticancer agents to treat liver cancer. Here, a novel chalcone derivative was synthesized and evaluated for anticancer activity in vitro against liver cancer cell lines (HepG2, SNU-423, SMMC7221, and SNU-398). The chalcone hybrid 9 displayed the antiproliferative effect against HepG2, SNU-423, SMMC7221 and SNU-398 cells with IC50 values of 0.9 mu M, 2.7 mu M, 6.2 mu M and 4.6 mu M, respectively. Cellular mechanisms showed that derivative 9 could obviously inhibit HepG2 cells growth and colony formation in a concentration-dependent manner. Analogue 9 inhibited the migration by regulating the expression levels of migration-releated markers and transcription factors (Snail and Slug). Tubulin polymerization inhibition assay illustrated that chalcone hybrid 9 might be a potent tubulin polymerization inhibitor. Importantly, compound 9 displayed the antitumor activity against liver cancer HepG2 cells in vivo with the low toxicity toward mice. Therefore, compound 9 as a novel tubulin polymerization inhibitor deserves further investigation to treat liver cancer.
