A new series of benzimidazole/benzoxazole linked beta-carbolines (9a-j) were rationally designed and synthesized by combining two different anti-cancer fragments. The new hybrid beta-carbolines are subjected to anti-cancer screening against four different human cancer cell lines such as MCF-7 (breast), A549 (lung), Colo-205 (colon) and A2780 (ovarian) by using standard MIT assay. These hybrid beta-carbolines exhibited significant and high fold anti-cancer activity against MCF-7 cell lines than reference standard. They are also proved to be effective against A549 and Colo-205 cell lines. Further, compound 9b, 9c from benzimidazole and 9i from benzoxazole series have exhibited maximum anti-cancer activity among these hybrid beta-carbolines. Later, all of the hybrid beta-carbolines were subjected to molecular interaction analysis against a few selected kinase targets such as cdc-like kinase (CLK-1 to CLK-4), epidermal growth factor reductase (EGFR) kinase, protein (ATR) kinase along with APC-Asef interface. The violin plot of binding energies of 9a-9j have suggested them as good kinase binders. Result interpretation suggested hybrid beta-carbolines as promising CLK binders. The anti-cancer data of new hybrid beta-carbolines against MCF-7 cell lines are in agreement with parent beta-carboline skeleton. (C) 2020 Elsevier B.V. All rights reserved.

The PCN pincer Pd(II) complexes 4a-c with (phosphinito)aryl benzimidazole ligands were conveniently synthesized by one-pot phosphorylation/palladation reaction of a (2-benzimidazolyl)-containing m-phenol derivative 3. The three complexes were well characterized by spectroscopic methods, elemental analysis and their molecular structures were further determined by X-ray single-crystal diffraction. The Pd(II) center in each complex adopts a typical distorted-square-planar geometry. With a catalyst loading of 0.25-0.5 mol%, complex 4a could effectively catalyze C-H arylation of benzothiazole, benzoxazole and thiazole with various aryl iodides in the presence of Cul as a cocatalyst.

alpha-Substituted amines are present in a myriad of biologically active natural and synthetic products. With the objective of developing atom-economical reactions, a panel of synthetic methods allowing the direct functionalization of C(sp(3))-H bonds adjacent to the nitrogen atom have been developed. The field remains dominated by the sequence a-lithiation/addition on an electrophile even if the use of reactive organolithium reagents is not compatible with all functional groups. Over the past ten years, an increasing interest has been devoted to metal-catalyzed C-H-activation, some studies being specially dedicated to C(sp(3))-H bond activation. Notably, this approach has been envisioned to perform direct alpha-functionalization of amines. The aim of this article is to give an overview of synthetic methods for transition metal-catalyzed alpha-allcylation of amines by C(sp(3))-H bond activation. (C) 2018 Published by Elsevier Ltd.

Carbazoles and hydrazone-bridged thiazole-pyrrole derivatives are known to exhibit a wide range of biological activities including antimicrobial activity. This work is a further extension of their biological activities that identifies a total of 13 of these derivatives as new alpha-glucosidase inhibitors. The carbazole derivatives exhibited noncompetitive inhibition of the enzyme with the inhibitor possessing the 2-benzoimidazole substitution being the most potent in the series. Compounds possessing the 2-benzothiazole, 2-benzoxazole and quinoline groups were also found to be promising for enzyme inhibition. The hydrazone-bridged thiazole-pyrrole derivatives showed competitive enzyme inhibition with a number of groups responsible for potent enzyme inhibition including 4-nitrophenyl, 4-bromophenyl, and 4-methoxyphenyl groups. Moreover, the hydrazone derivatives with unsubstituted pyrrole ring were found to be more favorable to alpha-glucosidase inhibition than the ones possessing the methyl-substituted ring. The current work may provide new structural and functional diversity to drug discovery of promising alpha-glucosidase inhibitors as anti-diabetic drugs.

The design of reusable high-performance heterogeneous catalysts via the immobilization of chemical and biochemical species on magnetic nanoparticles increases the efficiency of catalytic systems by facilitating easy, fast, and clean separation processes. Laccase and 4-amino-2,2,6,6-tetramethylpiperidine-1-oxyl were separately immobilized on amine functionalized iron (II, III) oxide nanoparticles with covalent bonding using glutaraldehyde as a coupling reagent. The prepared catalyst was used to synthesize 12 benzoxazole and benzimidazole derivatives. The one-pot, two-step enzymatic aerobic oxidation reaction included the condensation of insitu-produced salicylaldehyde derivatives with aromatic amines, followed by an enzymatic dehydrogenation process. Optimal reaction conditions consisted of a citrate buffer (10mM, pH4.5) at 40 degrees C for an incubation time of 10 h and a heterogeneous catalyst containing immobilized laccase (80 mg, 100 U) and immobilized 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) (40 mg, 2 mol%). The catalyst retained more than 85% of its initial activity after 10 runs. In addition to the potential for reuse without significant losses in performance, eco-friendly attributes of this catalytic system include its high catalytic activity and the ease with which it can be recovered from the reaction mixture using an external magnet.

Adenylate-forming enzymes (AFEs) are a mechanistic superfamily of proteins that are involved in many cellular roles. In the biosynthesis of benzoxazole antibiotics, an AFE has been reported to play a key role in the condensation of cyclic molecules. In the biosynthetic gene cluster for the benzoxazole AJI9561, AjiA1 catalyzes the condensation of two 3-hydroxyanthranilic acid (3-HAA) molecules using ATP as a co-substrate. Here, the enzymatic activity of AjiA1 is reported together with a structural analysis of its apo form. The structure of AjiA1 was solved at 2.0 angstrom resolution and shows a conserved fold with other AFE family members. AjiA1 exhibits activity in the presence of 3-HAA (K-m = 77.86 +/- 28.36, k(cat) = 0.04 +/- 0.004) and also with the alternative substrate 3-hydroxybenzoic acid (3-HBA; K-m = 22.12 +/- 31.35, k(cat) = 0.08 +/- 0.005). The structure of AjiA1 in the apo form also reveals crucial conformational changes that occur during the catalytic cycle of this enzyme which have not been described for any other AFE member. Consequently, the results shown here provide insights into this protein family and a new subgroup is proposed for enzymes that are involved in benzoxazole-ring formation.

Detailed pictures of the excited-state intramolecular proton transfer (ESIPT) of 2,5-bis(2′-benzoxazolyl)hydroquinone (BHQ) and its water cluster have been investigated by dynamics simulations on the first lowest excited energy using time-dependent density functional theory (TD-DFT). We focused on the structural, photophysical and dynamic properties of BHQin the absence and presence of water molecules through intermolecular hydrogen bonds (interHBs). Our dynamics simulations reveal three possible mechanisms of the ESIPT processes: i) no proton transfer (No PT); ii) single PT (SPT); and iii) double PT (DPT), that could take place within the PT time of 160 fs via intrinsic intramolecular hydrogen bonds (intraHBs). The ESIPT mechanism of isolated BHQ elucidates that back PT is likely to be found at 64% rather than the SPT (32%) and DPT (4%), which is in good agreement with the experiments of dual fluorescence from di-enol and mono-keto emissions. Notably, the results from BHQ with water (BHQ-(H20)2) reveal that the participation of water might produce a remarkable effect on promoting the SPT process up to 60% and DPI up to 7 times when compared to conditions of no water. The simulated probability of PT is well related to possible PT mechanisms regarding different tautomers in the fluorescence spectra found in previous experiments. The existence of di-keto tautomer arose from the DM’ of BHQ and its water cluster and was not observed in the UV/Vis spectrum. (C) 2019 Elsevier B.V. All rights reserved.

A simple approach for the S-arylation of azole-2-thiones with trivalent organobismuth reagents is described. The reaction of azole-2-thiones containing a heterocyclic ring (benzothiazole, benzoxazole, benzimidazole, and pyrimidine) with triarylbismuthines in the presence of CuI (10 mol%) and 1,10-phenanthroline (10 mol%) under aerobic conditions afforded S-arylated coupling products in moderate-to-high yields. Triarylbismuthines gave better results compared to various aryl donors based from other typical elements such as antimony, silicon, tin, and tellurium. This reaction is the first example of the Cu-catalyzed S-arylation of azole-2-thiones using an organobismuth compound.

A halochromic fluorescence dye was synthesized to fabricate acid-gas sensing textiles. The dye has a maximum absorption at 436 nm and stokes shift of 54 nm in ethanol, which means that it exhibits a typical fluorescence color of greenish yellow. The dye was designed to have good substantivity toward hydrophobic and chemical resistant polyethylenic fibers, such as high molecular weight polyethylene (HMWPE) fibers, by introducing di-butyl and t-butyl groups on coumarin and benzoxazole moieties of the chromophore, respectively. The fluorescence dye showed the change of both color and fluorescence emission properties not only in a solution by addition of hydrochloric acid but also inside the HMWPE fiber on exposure to gas phase hydrogen chloride even at relatively low concentrations. From the repeat test, the sensing performance was maintained reversibly even after 20 repeat cycles of adsorption and desorption of gas phase hydrogen chloride. The HMWPE fabrics dyed with the fluorescence dye can be washable by showing fastness of rating 4-5 to washing.
