Room-temperature redox-active liquid crystals composed of tetraazanaphthacene derivatives

Liquid-crystalline (LC) N-heteroacenes, tetraazanaphthacene (TANC), and fluoflavin (FFV) were synthesized, and their self-assembly into columnar LC structures at room temperature was investigated. LC TANC and LC FFV functioned as an electron acceptor and electron donor, respectively. A TANC/FFV LC mixture showed ESR activity in the presence of a strong base. Copyright

Synthesis and optical properties of diaza- and tetraazatetracenes

A series of functionalized diaza- and tetraazatetracenes was synthesized, either by condensation of an aromatic diamine with an ortho-quinone/ diethyloxalate followed by chlorination with POCl3 to give diazatetracenes or by palladium-catalyzed coupling of a phenylenediamine with various 2,3-dichloroquinoxalines to give tetraazatetracenes (after oxidation with MnO2). Representative examples included halogenated and nitrated derivatives. The optical properties of these azatetracenes were discussed with respect to their molecular structures and substitution patterns. The diazatetracenes and tetraazatetracenes formed two different groups that had significantly different electronic structures and properties. Furthermore, 1,2,3,4-tetrafluoro-6,11-bis((triisopropylsilyl)ethynyl)benzo[b]phenazine was synthesized, which is the first reported fluorinated diazatetracene. Single-crystal X-ray analysis of this compound is reported.

Synthesis and anticonvulsant activity of novel 2- and 3-[4-(trisubstituted pyridyl)-phenylamino]- and 2-[3- and 4-(trisubstituted pyridyl)-phenoxy]-quinoxaline derivatives

A series of novel quinoxaline derivatives linked to a pyridine moiety through phenylamino or phenoxy residue was synthesized and evaluated as candidate anticonvulsants. The synthesis was achieved through reaction of 2,3-dichloroquinoxaline (1) with an equimolar amount of 4-aminoacetophenone to give compound 2 which is considered as an important synthon for the construction of a pyridine ring via several synthetic routs. Some compounds were synthesized through formation of the intermediate alpha,beta-unsaturated compounds which, in turn, were allowed to react with malononitrile to give the corresponding alkoxypyridines (8-17). Compounds 18-21 were synthesized by a one-pot simple reaction between 2, the appropriate aldehyde, and malononitrile in sodium alkoxide solution. Moreover, they can be synthesized through reaction of compound 2 and arylidenemalononitrile in sodium alkoxide. The phenoxy analogues were prepared by reaction of 1 with 4-hydroxyacetophenone or 3-hydroxybenzaldehyde to give 22 and 27, respectively. These compounds, in turn, were allowed to react with malononitrile and the proper carbonyl compound in presence of sodium alkoxide in a one-pot reaction technique to give the target compounds. Biological evaluation of the prepared compounds showed that some of them are potent anticonvulsant agents. The detailed synthesis, spectroscopic and biological data are reported.

Modern approaches to the synthesis and prospects for the use of cyanine dyes containing functional groups in the N-substituents

Methods for the synthesis of mono-, tri-, penta-and heptamethine cyanine dyes containing functional groups in N-substituents are considered. Approaches suitable for the preparation of both symmetrical and unsymmetrical cyanine dyes are presented. Examples of the practical use of this type of cyanine dyes as fluorescent labels and probes in biology and medicine, as well as of components of photoactive supramolecular structures, photosensitizers and photo-and electroluminescent materials are given.

Design, synthesis, and molecular docking studies of new [1,2,4]triazolo[4,3-a]quinoxaline derivatives as potential A2B receptor antagonists

Abstract: Many shreds of evidence have recently correlated A2B receptor antagonism with anticancer activity. Hence, the search for an efficient A2B antagonist may help in the development of a new chemotherapeutic agent. In this article, 23 new derivatives of [1,2,4]triazolo[4,3-a]quinoxaline were designed and synthesized and its structures were confirmed by different spectral data and elemental analyses. The results of cytotoxic evaluation of these compounds showed six promising active derivatives with IC50 values ranging from 1.9 to 6.4 muM on MDA-MB 231 cell line. Additionally, molecular docking for all synthesized compounds was performed to predict their binding affinity toward the homology model of A2B receptor as a proposed mode of their cytotoxic activity. Results of molecular docking were strongly correlated with those of the cytotoxic study. Finally, structure activity relationship analyses of the new compounds were explored.

Construction of a bidentate arsenic ligand library starting from a cyclooligoarsine

Bidentate ligands are, needless to say, pivotal in organo-metallic chemistry. In contrast to phosphorus ligands, practical synthetic protocols for the arsenic analogues remain to be developed, resulting in a lack of bidentate arsenic ligands. Herein the methods that we have recently developed were applied for bidentate arsenic ligands whose frameworks are well known in phosphorus ligand systems such as dppe, dppp, dppf, xantphos, etc. The palladium dichloride complexes of the obtained ligands were synthesized and used for the Suzuki-Miyaura coupling reaction.

Cavitands as Versatile Molecular Receptors

X-ray crystal structure of 3*2PhF and 1H NMR complexation studies in solution reveal the strong tendency of cavitand 3 to selectively bind aromatic guests in organic solution.The association constants (Ka) for eight 1:1 caviplexes formed in acetone-d6 were determined.The solvation effect is largely responsible for the relatively low Ka values observed.The orientation assumed by the guests inside the cavity is determined by dipole-dipole interactions between the host and the guest; additional CH3-? interactions are present in the case of 3*3(CH3)2CO.The modification of the structure of 3 by introducing a suitable and furtherly modifiable substituent allowed the synthesis of optically pure chiral cavitand 5. 1H NMR complexation studies of 5 in acetone-d6 reveal that the CH2OH group perching on top of the cavity rim affects the selectivity but not the orientation of the included aromatic guests for the 1:1 caviplexes formed.

Synthesis and antimicrobial activity of some novel quinoxalines

2-Hydrazino-3-chloroquinoxaline 2 was prepared and reacted with active methylene compounds, potassium thiocyanate, carbon disulfide, phenylisothiocyanate, acetic acid, ethyl chloroformate, triethyl orthoformate, and Lawessen’s reagent (LR) to give a new class of fused quinoxalines 4-16, respectively. Also, 2,3-dihydrazinoquinoxaline 3 was prepared and reacted with carbon disulfide, phenyl isothiocyanate, and triethyl orthoformate to give the corresponding di[1,2,4] triazolo-[4,3-a:3?,4?-c]-quinoxalines 17-19, respectively. Reaction of 3 with LR gave the corresponding di[1,2,4,3] triazophospholo[4,5-a:5?,4?-c]quinoxaline-1,6-dithione (20). It was found that all synthesized compounds exhibit antimicrobial activity and that compound 20 had a broad spectrum of activity. Copyright Taylor & Francis Group, LLC.
