Benzotriazoles (4-6) were synthesized which were further reacted with different substituted benzoic acids and phenacyl bromides to synthesize benzotriazole derivatives (7-40). The synthetic compounds (7-40) were characterized via different spectroscopic techniques including EI-MS, HREI-MS, H-1-, and C-13 NMR. These molecules were examined for their anti-hyperglycemic potential hence were evaluated for alpha-glucosidase and alpha-amylase inhibitory activities. All benzotriazoles displayed moderate to good inhibitory activity in the range of IC50 values of 2.00-5.6 and 2.04-5.72 mu M against alpha-glucosidase and alpha-amylase enzymes, respectively. The synthetic compounds were divided into two categories A and B, in order to understand the structure-activity relationship. Compounds 25 (IC50 = 2.41 +/- 131 mu M), (IC50 = 2.5 +/- 1.21 mu M), 36 (IC50= 2.12 +/- 1.35 M), (IC50 = 2.21 +/- 1.08 mu M), and 37 (IC50 = 2.00 +/- 1.22 mu M), (IC50 = 2.04 +/- 1.4 mu M) with chloro substitution/s at aryl ring were found to be most active against alpha-glucosidase and alpha-amylase enzymes. Molecular docking studies on all compounds were performed which revealed that chloro substitutions are playing a pivotal role in the binding interactions. The enzyme inhibition mode was also studied and the kinetic studies revealed that the synthetic molecules have shown competitive mode of inhibition against alpha-amylase and non-competitive mode of inhibition against alpha-glucosidase enzyme.

Herein, we present the first report on TiO2 NPs based hybrid nano-reactor designed and synthesized via N-(2-amino ethyl)-3-amino propyl trimethoxy silane (AAPTMS) functionalization of graphene oxide (GO). The assynthesized nano-reactor was characterized by means of several analytical-cum-spectroscopic techniques that support the successful attempt for the synthesis of TiO2@AAPTMS-rGO. Further, the present catalyst was evaluated for its catalytic performance towards an expedient access to biologically relevant synthesis of 2,4,5-triaryl imidazoles. The functional sites of TiO2@AAPTMS-rGO direct the catalysis from the reactant to product with high atom economy, shorter reaction time and excellent yields. Moreover, the present catalyst TiO2@AAPTMS-rGO shows promising reusability for several catalytic cycles. It also provides a robust approach for 2,4,5-triaryl imidazoles with improved performance and without significant loss in catalytic activity. Further, this catalyst can be upgraded for other organic transformations leading to numerous pharmaceuticals and environment benefits.

This viable transformation provides a variety of novel substituted hydroxyisoindolo[1,2-b]quinazolinone compounds in moderate to good yields. Additionally, the reaction is performed with toluene in place of benzaldehyde by using an excess amount of tert-butyl hydroperoxide (TBHP) as the oxidant in good yield.

Thirty-four seco-3’R,4’R-disubstituted-2′,2′-dimethyldihydropyrano[2,3-f]chromone (seco-DSP) derivatives were designed, synthesized and evaluated for chemo-reversal activity when combined with paclitaxel or vincristine in P-gp overexpressing A2780/T and KB-VIN drug-resistant cancer cell lines. Most of the compounds displayed moderate to significant MDR reversal activities. Compound 7e showed the most potent chemo-sensitization activity with more than 1471 reversal ratio at a concentration of 10 mu M, which was higher than verapamil (VRP) (212-fold). Unexpectedly the newly synthesized compounds did not show chemosensitization activities in a non-P-gp overexpressing cisplatin resistant human ovarian cancer cell line (A2780/CDDP), implying that the MDR reversal effects might be associated with P-gp overexpression. Moreover, the compounds did not exhibit significant anti-proliferative activities against non-tumorigenic cell lines (HUVEC, HOSEC and T29) compared to VRP at the tested concentration and might be safer than VRP. In preliminary pharmacological mechanism studies, the compounds increased accumulation of DOX and promoted P-gp ATPase activity in A2780/T cell lines. Western blot analysis indicated they did not affect the expression level of P-gp in the tested MDR cell lines. Thus, further studies on these seco-DSP derivatives are merited with the goal of developing a desirable chemosensitizer drug candidate. (C) 2020 Elsevier Masson SAS. All rights reserved.

Indomethacin is a well-known nonsteroidal anti-inflammatory drug that has cytotoxic activity. In this study, a new series of structurally related indomethacin analogues was synthesized using simple chemical approaches, and their cytotoxic effects against five different human cancer cell lines (colon cancer cell lines HCT-116, HT-29 and Caco-2, hepatic cell line HepG-2 and breast cell line MCF-7) were evaluated. Most of the tested compounds displayed potent anti-cancer activity, especially against the three colon cancer cell lines. Among all tested derivatives, compound 12 demonstrated the most potent cytotoxic activity compared to the parent drug indomethacin and the reference compound 5-fluorouracil, with IC 50 values ranging 0.83-1.54 mu M. A mechanistic study of the most active compound against the HCT-116, HT-29 and Caco-2 cell lines revealed cell cycle arrest during the G2/M phase. Compound 12 was found to induce apoptosis through the up-regulation of Bax and p53 by 7.4 and 8.5-fold, respectively, and also the downregulation of Bcl-2 by 3.2-fold compared to the control. Western blot assay was performed on HCT-116 cells and demonstrated marked inhibition of CDK1 and Bcl-2 expression together with an increase in the expression of caspase-3, Bax and p53 in a concentration-dependent manner. Finally, a prediction of the chemo-informatic properties of compounds 11 and 12 indicated that they are orally bioavailable with no permeation of the blood-brain barrier. (C) 2020 Elsevier B.V.

This study presents one-pot multicomponent preparation of 1,8-dioxo-octahydroxanthene derivatives under very mild conditions using cobalt-incorporated sulfated zirconia (ZrO2/SO42-/Co) as an efficient heterogeneous recyclable multifunctional nanocatalyst. The nanocatalyst was successfully characterized by FTIR, XRD, TGA, FE-SEM, TEM, ICP, and EDX analyses. The nanoparticles have a mean size of 13 nm, with a combination of the monoclinic-tetragonal crystal structure. A wide scope of aldehydes bearing different functional groups was condensed with dimedone and/or 1,3-cyclohexadione in water at room temperature with good-to-high yields at short reaction times. The catalyst can be efficiently recovered and reused several times without much loss of its activity. Besides, hot filtration test gives more insight into the heterogeneous nature of the catalyst. Finally, a plausible mechanism for this transformation was proposed. Graphical abstract A facile and convenient method for the synthesis of 1,8-dioxo-octahydroxanthenes has been developed using cobalt-incorporated sulfated zirconia as an efficient recyclable nanocatalyst.

In subsurface bioremediation, electron donor addition promotes microbial Fe(lII)-oxide mineral reduction that could change soil pore structure, release colloids, and alter soil surface properties. These processes in turn may impact bioremediation rates and the ultimate fate of contaminants. Columns packed with water-stable, Fe-oxide-rich soil aggregates were infused with acetate-containing artificial groundwater and operated for 20 d or 60 d inside an anoxic chamber. Soluble Fe(II) and soil colloids were detected in the effluent within one week after initiation of the acetate addition, demonstrating Fe(III)-bioreduction and colloid formation. Diffusible Br-, less diffusible 2,6-difluorobenzoate (DFBA), and non-diffusible silica-shelled silver nanoparticles (SSSNP) were used as tracers in transport experiments before and after the bioreduction. The transport of Br- was not influenced by the bioreduction. DFBA showed earlier breakthrough and less tailing after the bioreduction, suggesting alterations in flow paths and soil surface chemistry during the 20-d bioreduction treatment. Similarly, the bioreduction increased the transport of SSSNP very significantly, with mass recovery increasing from 1.7% to 25.1%. Unexpectedly, the SSSNP was completely retained in the columns when the acetate injection was extended from 20 to 60 d, while the mass recovery of DFBA decreased from 89.1% to 84.1% and Br showed no change. The large change in the transport of SSSNP was attributed to soil aggregate breakdown and colloid release (causing mechanical straining of SSSNP) and the exposure of iron oxide surfaces previously unavailable within aggregate interiors (facilitating attachment of SSSNP). These results suggest a time dependent fashion of microbial effect on the transport of diffusivity-varying tracers. (C) 2018 Elsevier Ltd. All rights reserved.
