Discovery of 6-Arylurea-2-arylbenzoxazole and 6-Arylurea-2-arylbenzimidazole Derivatives as Angiogenesis Inhibitors: Design, Synthesis and in vitro Biological Evaluation

We embarked on a structural optimization campaign aimed at the discovery of novel anti-angiogenesis agents with previously reported imidazole kinase inhibitors as a lead compound. A library of 29 compounds was synthesized. Several title compounds exhibited selective inhibitory activities against vascular endothelial growth factor receptor 2 (VEGFR-2) over epidermal growth factor receptor (EGFR) kinase; these compounds also displayed selective and potent antiproliferative activity against three cancer cell lines. The newly synthesized compounds were evaluated for anti-angiogenesis activity by chick chorioallantoic membrane (CAM) assay. Among them, 1-(2-(2-chlorophenyl)benzo[d]oxazol-5-yl)-3-(4-(trifluoromethoxy)phenyl)urea (compound 5 n) showed the most potent anti-angiogenesis capacity, efficient cytotoxic activities (in vitro against human umbilical vein endothelial cells (HUVEC), H1975, A549, and HeLa cell lines, with respective IC50 values of 8.46, 1.40, 7.61, and 0.28 mu m), and an acceptable level of VEGFR-2 kinase inhibition (IC50=0.25 mu m). Molecular docking analysis revealed 5 n to be a type II inhibitor of VEGFR-2 kinase. In general, these results indicate that these 6-arylurea-2-arylbenzoxazole/benzimidazole derivatives are promising inhibitors of VEGFR-2 kinase for potential development into anti-angiogenesis drugs.

Novel benzoxazole derivatives featuring rhodanine and analogs as antihypergycemic agents: synthesis, molecular docking, and biological studies

A novel series of benzoxazolyl linked benzylidene based rhodanine and their cyclic analogs were synthesized, characterized and evaluated for their alpha-amyloglucosidase inhibitory activity. Out of eight target compounds, two compounds (4b and 5b) displayed potent inhibitory activity against alpha-amyloglucosidase with IC50 values in the range of 0.24 +/- 0.01-0.94 +/- 0.01 A mu M as compared to standard drug acarbose. Among all the tested compounds, compound 5b containing rhodanine at 3-position of phenyl was found to be the most active inhibitor of alpha-amyloglucosidase. Docking studies showed the existence of potential H-bonding interactions between synthesized compounds and alpha-glucosidase which might be responsible for good biological activity.

Potential-induced phase transition of benzoxazole-2-thiol, naphthaleneoxazole-2-thiol and anthraceneoxazole-2-thiol monolayers on gold electrodes

In the present work we report the electrochemical characterization of self-assembled monolayers (SAMs) of N, O-heteroaromatic thiols, namely benzoxazole-2-thiol (1), naphthaleneoxazole-2-thiol (2) and anthraceneoxazole-2-thiol (3) on polycrystalline gold electrodes. SAMs were formed by immersion of pre-treated gold electrodes into ethanolic solutions of the title compounds. The modified electrodes exhibited a decrease of electroactivity, as found by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS), in comparison to bare electrodes according to the length of the aromatic p-system. In addition, reductive desorption experiments confirmed that of the three compounds, 3 formed the most stable SAMs in agreement with EIS measurements which revealed better blocking properties against the redox couple in a test electrolyte indicating a charge transfer determined behaviour in the case of longer molecules. The charge transfer resistances revealed a trend towards higher resistances in the case of 3. When performing EIS at various starting potentials and different electrolyte concentrations, it was found that at certain critical potentials (E-crit) a potential-induced structural change of the SAM occurred, with E-crit(1) > E-crit(2) > E-crit(3). In the case of SAMs of 3 the nature of this alteration was investigated via scanning tunnelling microscopy and found to presumably be caused by an order-disorder-transition. (C) 2018 Elsevier Ltd.

Synthesis of 2-(arylsulfenyl)azoles by copper-catalyzed S-arylation of azole-2-thiones with triarylbismuthines

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.

Chemical and structural characterization of problematic suspended particles enriched from fluidized catalytic cracking slurry oil

Suspended particles (SPs) were separated from an FCC Slurry Oil (SLO) via centrifugation with the aid of toluene-dilution. Further solvent extraction of SPs with CS2/toluene (50 V/V%) mixed solvent would generate solvent extraction insolubles (SEINS) and solubles (SES). They were sent for a series of chemical and structural characterizations, respectively, in the hope of providing clues to address issues from sedimentation and clarification processes. It was found that SPs were composed of catalyst fragments and organic substances wrapped around them, serving as a shield. The characterizations from TEM and XPS strongly suggested that the outer surface of SEINS was sufficient in oxygen-containing sites (organic functional groups and aluminosilicate), while the outer surface of SPs was not. High oxygen content and almost same nitrogen content of SES, comparable with that of asphaltenes, were detected through XPS characterization. This rationalized the strong adsorption of SES on SEINS in the form of a tedious solvent extraction process. A new structure of SPs has thus been described on the basis of these characterizations. Design sedimentation experiments verified the SPs’ structure. Furthermore, the experiments offered a promising way for acquiring high clarification efficiency with rather low usage of sinking agent through solvent pretreatment.

Synergetic Effect of Iron-Doped Acidic Multi-Walled Carbon Nanotubes in the Synthesis of Diverse Substituted Five-Membered Heterocyclic Compounds

Iron-doped acidic multi-walled carbon nanotubes (Fe@acidic-MWCNs) were synthesized using the chemical vapor deposition (CVD) process in the presence of acetylene and ferrocene as the sources of carbon and iron nanoparticles, respectively. The Fe@acidic-MWCNs was fully characterized by inductively coupled plasma (ICP), X-ray diffraction (XRD), scanning electron microscopy (SEM), atomic force microscopy (AFM), Raman, and FT-IR analysis. In continuation, the synergetic effect of iron nanoparticles and acidic groups of the Fe@acidic-MWCNs was studied through the synthesis of substituted five-membered heterocyclic compounds including 2-substituted benzimidazoles, 2-substituted benzothiazoles, 2-substituted benzoxazoles, and 1-substituted tetrazoles. Moreover, the 2-substituted benzimidazoles were investigated by two different methods. In general, Fe@acidic-MWCNs catalyst showed good to excellent catalytic activity. Finally, the Fe@acidic-MWCNs catalyst displayed a high reusability and stability in the synthesis of 3 a, 5 a, 7 a, 9 a, and 11 a.

Melatonin receptor ligands: A pharmaco-chemical perspective

Melatonin MT(1)and MT(2)receptor ligands have been vigorously explored for the last 4 decades. Inspection of approximately 80 publications in the field revealed that most melatonergic ligands were structural analogues of melatonin combining three essential features of the parent compound: an aromatic ring bearing a methoxy group and an amide side chain in a relative arrangement similar to that present in melatonin. While several series of MT2-selective agents-agonists, antagonists, or partial agonists-were reported, the field was lacking MT1-selective agents. Herein, we describe various approaches toward the development of melatonergic ligands, keeping in mind that most of the molecules/pharmacophores obtained were essentially melatonin copies, even though diverse tri- or tetra-cyclic compounds were explored. In addition to lack of structural diversity, only few studies examined the activity of the reported melatonergic ligands in vivo. Moreover, an extensive pharmacological characterization including biopharmaceutical stability, pharmacokinetic properties, specificity toward other major receptors to name a few remained scarce. For example, many of the antagonists described were not stable in vivo, were not selective for the melatonin receptor subtype of interest, and were not fully characterized from a pharmacological standpoint. Indeed, virtual screening of large compound libraries has led to the recent discovery of potent and selective melatonin receptor agonists and partial agonists of new chemotypes. Having said this, the melatonergic field is still lacking subtype-selective melatonin receptor antagonists active in vivo, which are critical to our understanding of melatonin and melatonin receptors’ role in basic physiology and disease.

Enhanced, hydrophobic, fluorine-containing, thermally rearranged (TR) nanofiber membranes for desalination via membrane distillation

Though membrane distillation (MD) has been considered as a promising desalination process, it is still required to develop a desirable membrane which has high water flux and long-term stability for practical use in the MD process. In our previous work, thermally rearranged nanofiber membranes (TR-NFMs), which exhibited high water flux (80 kg m(-2) h(-1)) and salt rejection (> 99.99%) as well as outstanding long-term stability (more than 180 h), were first introduced as a promising candidate for MD applications. However, nascent TR-NFM is susceptible to fluctuations in operating conditions due to insufficient liquid entry pressure with water (LEPw). In continuation of our enhanced hydrophobic TR-NFM study, we develop fluorine-containing thermally-rearranged nanofiber membranes (F-TR-NFMs) for MD applications for the first time. F-TR-NFMs showed enhanced hydrophobic properties such as high water contact angle (143 degrees), high LEPw (1.3 bar), and high effective evaporation area (EEA) due to the introduction of fluorine atoms in the backbone of the TR membrane. As the result, the developed F-TR-NFMs exhibited outstanding MD performance (114.8 kg m(-2) h(-1) of water flux and > 99.99% of salt rejection at feed and permeate temperatures of 80 degrees C and 20 degrees C, respectively) and excellent energy efficiency (52.1% at feed and permeate temperatures of 50 degrees C and 20 degrees C, respectively). The long-term stability of F-TR-NFM is also investigated over more than 250 h of operation time.
