Some new 2-((4-((1-aryl-1H-1,2,3-triazol-4-yl)methyl)piperazin-1-yl)methyl)benzo[d] oxazoles (4a-j) were synthesized through Cu(I) catalyzed [3+2] cycloaddition reaction between 2-((4-(prop-2-yn-1-yl)piperazin-1-yl)methyl)benzo[d]oxazole (3) and several aryl azides. The in vitro anticancer and antibacterial activities evaluation revealed that compounds 4g, 4f, and 4d possess good activities, whereas the remaining compounds are associated with moderate to low activities.

A novel series of benzoxazole linked combretastatin derivatives (11a-11n) have been synthesized and confirmed by H-1 NMR, C-13 NMR, and Mass spectral analysis. The synthesized compounds (11a-11n) were screened for anticancer activity against three human cancer cell lines, Breast (MCF-7), Lung (A549), and Melanoma (A375). Most of the compounds exhibit moderate to potent anticancer activity. Among the compounds, 11g, 11h, 11l, 11m, and 11n showed more potent activity than the positive control Doxorubicin. In addition, compounds 11g, 11l, 11m, and 11n were carried out their molecular docking studies on EGFR receptor (PDB ID: 4hjo) and results indicated that 11g and 11l have strong binding interactions with the receptor. It was found that the binding energy calculations were in good agreement with the observed IC50 values.

Aim: Obtain radioimages of amyloid-beta fibers using Tc-99m-complexes. Methodology: Tridentate thiosemicarbazone and thiocarbonohydrazone ligands containing fragments (stilbene, azobenzene, benzothiazole or benzoxazole) with affinity for amyloid-beta fibers and its Re(I) complexes have been prepared. The molecular structures of several ligands and complexes were determined by x-ray diffraction. Binding affinity studies toward A beta 1- 42 fibers were performed for the ligands and Re(I) complexes. The ability of formation of some Tc-99m(I) complexes, their biodistribution and in vivo stability have been established. Results & conclusion: Complexes of stilbene and benzothiazole thiosemicarbazonates show similar affinity for amyloid-beta fibers to the free ligand. These Tc-99m complexes present a reasonable in vivo stability and a low capability to cross the blood-brain barrier although not sufficient to brain amyloid imaging.

The appropriate choice of redox mediator can avoid electrode passivation and overpotential, which strongly inhibit the efficient activation of substrates in electrolysis.92-86-4, Name is 4,4′-Dibromobiphenyl, molecular formula is C12H8Br2.

Fluorinated aromatics is generally chosen as mesogenic cores to design novel liquid crystal compounds. Here, a series of benzoxazole derivatives with laterally multifluorinated biphenyl units, 2-(3 ‘,3-difluoro -4 ‘-alkoxy-1,1 ‘-biphenyl-4-yl)-benzoxazole derivatives (coded as nPF(3)PF(3)Bx), are synthesized and characterized, where methyl and nitro moieties are selected as terminal groups to investigate the effects of different polar substituents on the liquid crystal properties. The compounds nPF(3)PF(3)Bx show enantiotropic mesophases with mesophase ranges of 0-40 degrees C and 0-63 degrees C on heating and cooling for hydrogen-terminated derivatives (nPF(3)PF(3)BH), 43-93 degrees C and 54-123 degrees C for methyl-terminated ones (nPF(3)PF(3)BM), 60-108 degrees C and 74-152 degrees C for nitro terminated ones (nPF(3)PF(3)BN), respectively. They exhibit photoluminescence emission peaks at 390-392 nm and UV-vis absorption bands with maxima at 327-330 nm, respectively. The results reveal that lateral multifluoro substituents lead to a decrease in melting/clearing points, while electron-withdrawing terminal nitro moiety results in increases in both melting point and mesophase range.

Seven new oxazoline, benzoxazole and benzimidazole derivatives were synthesized from 3 beta-acetoxyandrosta-5,16-dien-17-carboxylic, 3 beta-acetoxyandrost-5-en-17 beta-carboxylic and 3 beta-acetoxypregn-5-en-21-oic acids. Docking to active site of human 17 alpha-hydroxylase/17,20-lyase revealed that all oxazolines, as well as benzoxazoles and benzimidazoles comprising Delta(16) could form stable complexes with enzyme, in which steroid moiety is positioned similarly to that of abiraterone and galeterone, and nitrogen atom coordinates heme iron, while 16,17-saturated benzoxazoles and benzimidazoles could only bind in a position where heterocycle is located nearly parallel to heme plane. Modeling of the interaction of new benzoxazole and benzimidazole derivatives with androgen receptor revealed the destabilization of helix 12, constituting activation function 2 (AF2) site, by mentioned compounds, similar to one induced by known antagonist galeterone. The synthesized compounds inhibited growth of prostate carcinoma LNCaP and PC-3 cells at 96 h incubation; the potency of 2′-(3-hydroxyandrosta-5,16-dien-17-yl)-4′,5′-dihydro-1′,3′-oxazole and 2′-(3 beta-hydroxyandrosta-5,16-dien-17-yl)-benzimidazole was superior and could inspire further investigations of these compounds as potential anti-cancer agents.

Triazole bridged dendrimers with benzoheterazole surface groups were successfully synthesized in high yields by click chemistry via convergent approach. The photophysical properties of the dendrimers reveal that as the generation increases the light absorption ability also increases. The fluorescence intensity gradually decreases as the dendritic generation increases because of fluorescence quenching due to steric crowding of the dendritic arms. On increasing the number of benzoheterazole unit at periphery, the anodic peak was shifted to higher positive potential in cyclic voltammetry. When the synthesized triazole dendrimers are utilized as an additive in the redox couple of a DSSC, the lower generation dendrimers showed better current generating capacity with higher power conversion efficiency than the higher generation dendrimers.

A convenient and highly efficient palladium-catalyzed direct C2-arylation/heteroarylation ofN-substituted benzimidazole derivatives such asN-benzyl/3-chlorobenzyl/2,4,6-trimethylbenzyl/2,4,6-triisopropylbenzyl/aryl benzimidazoles with various aryl/heteroaryl bromides in the presence of Pd-PEPPSI (palladium-pyridine enhanced pre-catalyst preparation stabilization and initiation) complexes is reported. In order to that we have prepared a series of different symmetrical and unsymmetricalN,N ‘-diaralkyl benzimidazole-bearing Pd-PEPPSI complexes. Among all of the the prepared complexes, Pd-PEPPSI-3effectively tuned the reaction at a relatively higher rate under mild reaction conditions in an ethanol-water system. In addition, the catalytic process avoids the use of external ligand and additives. Further the reactivity was compared with commercially available copper-N-heterocyclic carbene catalyst, but the reaction was less successful. With the optimized reaction conditions, a wide range of 2-aryl/heteroaryl-N-substituted benzimidazoles were synthesized in good to excellent yields via Csp(2)-H/Csp(2)-X biaryl cross-coupling.

Benzothiadiazole (BTD) dyes are an important class of N,S-containing heterocycles that have remarkable optical properties. In this work, two new 2,1,3-benzothiadiazole dyes conjugated with benzothiazole and benzoxazole moieties were synthesized and the optical properties in solutions and in the solid state were investigated. The BTD dyes were synthesized in a single step from cydization of ortho-diamino benzothiazole and ortho-diamino benzoxazole dyes. The photophysical behavior of BTD precursor’s benzoxazole and benzothiazole dyes were also investigated. The dyes present absorption in the UVB (280-315 nm) and UVA (315-400 nm) wavelength and fluorescence in the blue-green visible region. The solvatochromic properties of the dyes were investigated indifferent solvents taking into account the solvent orientation polarizability (Delta f) and E-T (30) polarity solvent parameter. The ground and excited state dipole moments were determined by applying Bakshiev’s and Kawaski-Charnma-Viallet’s formulations. Furthermore, the spectroscopic properties of thin films and powders of BTD dyes were explored. (C) 2020 Elsevier B.V. All rights reserved.

The palladium complex of dendronized amine polymer (EG-Gn-Pd, n = 0, 1 and 2) having ethylene glycol-initiated polyepichlorohydrin as core was synthesized on a Merrifield resin support and was well characterized. Generally, palladium catalysts are known for carbon-carbon coupling reactions. Here, a developed catalyst was found to be good for benzoxazole synthesis. Higher generation dendronized polymer (EG-G2-Pd) was found to be better catalyst over lower generation dendronized polymers. Moreover, dendronized polymers were found to be a better catalyst over dendrigraft polymers. The catalyst reusability was checked and good yield was obtained for five cycles.
