The highly conjugated chelating ligands 5-(2-pyridyl)indolizino[2,3-b] pyrazine 1, 5-(2-pyridyl)indolizino[2,3-b]quinoxaline 2, and 8,9-dimethyl-5-(2-pyridyl)indolizino[2,3-b]quinoxaline 3 were prepared in one step, with good yields, from di-2-pyridylmethane and 2,3-dichloropyrazine, 2,3-dichloroquinoxaline, and 8,9-dimethyl-2,3-dichloroquinoxaline, respectively. Compounds 13 display long-wavelength absorption maxima in the green (1) and yellow (2 and 3) to give intensely coloured red and purple solutions, respectively. Bis(2,2?-bipyridyl)ruthenium(ii) and bis(4,4?- dimethyl-2,2?-bipyridyl)ruthenium(ii) complexes were prepared in moderate to good yields, characterized by NMR spectroscopy and mass spectrometry, and studied by cyclic voltammetry and absorption spectroscopy. Copper(ii) and silver(i) nitrate complexes of the ligands were prepared and complexes [Cu(NO3)2(1)], [Cu(NO3)2(2)] 2, and [Ag(NO3)(3)2] were characterized by X-ray crystallography. These structures revealed the planar nature of the ligands and confirmed the proposed chelating mode.

N-Phenyl-N-thiocarbamoyl-alpha- and beta-methyl-beta-alanines were converted into a series of 1,3-thiazole derivatives by treatment with chloroacetaldehyde and haloketones. The reaction of N-phenyl-N-thiocarbamoyl-beta-alanines and N-carbamoyl-N-phenyl-beta-alanines with 2,3-dichloro-1,4-naphthoquinone and 2,3-dichloroquinoxaline provided naphthoquinone- and quinoxaline-fused thiazoles and oxazoles, respectively. A number of the synthesized compounds exhibited good antibacterial activity against Staphylococcus aureus and Salmonella enteritidis with MIC and MBC values (62.5 and 125 mug/mL, respectively) which are the same or even lower than those for the antibiotic oxytetracycline.

A new class of PDE4 inhibitors were designed and synthesized via the InCl3 mediated heteroarylation of indoles and their further derivatization through the Pd(II)-catalyzed C[sbnd]H activation strategy. This effort allowed us to discover a series of 2-(1H-indol-3-yl)-quinoxaline based inhibitors possessing PDE4B selectivity over PDE4D and PDE4C. One of these compounds i.e. 3b (PDE4B IC50 = 0.39 ± 0.13 muM with ?27 and > 250 fold selectivity for PDE4B over PDE4D and C, respectively)showed effects in Zebrafish experimental autoimmune encephalomyelitis (EAE)model of multiple sclerosis when dosed at 3, 10 and 30 mg/kg intraperitoneally. Indeed, it halted the progression of the disease across all these doses tested. At an intraperitoneal dose of 30 mg/kg the compound 3b showed promising effects in adjuvant induced arthritic rats. The compound reduced paw volume, inflammation and pannus formation (in the knee joints)as well as pro-inflammatory gene expression/mRNA levels significantly in arthritic rats. Moreover, this compound was found to be selective towards PDE4 over other families of PDEs in vitro and safe when tested for its probable toxicity (e.g. teratogenicity, hepatotoxicity and cardiotoxicity)in Zebrafish.

We report the successful synthesis of a series of ethynylated dioxadiazaacenes and investigate their properties. We developed a modular Cu-based catalytic procedure to build up [1,4]dioxino[2,3-b]pyrazine motifs starting from only a few building blocks. TIPS-acetylene-substituted benzene-1,2-diol and naphthalene-2,3-diol were reacted with 2,3- dichloropyrazine, 2,3-dichloroquinoxaline, and 2,3-dichlorobenzoquinoxaline to give a set of six novel and well-soluble dioxadiazaacenes. Different reaction conditions for the coupling were tested. Copper catalysis is most effective and gave the best yield of dioxadiazaacenes. The resulting azaoxaacenes were characterized in terms of optical and electronic properties and crystal packing.

A direct and single-step method has been developed for the synthesis of mono and 2,3-disubstituted quinoxalines by using a AlCl3 induced (hetero)arylation of 2,3-dichloroquinoxaline. Both symmetrical and unsymmetrical 2,3-disubstituted quinoxalines can be prepared conveniently by using this method under appropriate reaction conditions. The reaction proceeds via C-C bond formation and can be utilized for the preparation of a variety of quinoxaline derivatives from readily available starting materials and reagents. The molecular structure of a representative compound was confirmed by single crystal X-ray diffraction study. Some of the compounds synthesized were tested for chorismate mutase inhibitory properties in vitro and one compound showed promising activity representing one of the few examples of chorismate mutase inhibition by a heteroarene based small molecule.

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.

An original synthesis of the fused pyranoquinoxaline dithiolene ligand qpdt2- is discussed in detail. The most intriguing step is the introduction of the dithiolene moiety by Pd-catalyzed carbon-sulfur coupling. The corresponding MoIVO complex (Bu4N)2[MoO(qpdt)2] (2) underwent reversible protonation in a strongly acidic medium and remained stable under anaerobic conditions. Besides, 2 was found to be very sensitive towards oxygen, as upon oxidation it formed a planar dithiin derivative. Moreover, the qpdt2- ligand in the presence of [MoCl4(tBuNC)2] formed a tetracyclic structure. The products resulting from the unique reactivity of qpdt2- were characterized by X-ray diffraction, mass spectrometry, NMR spectroscopy, UV/Vis spectroscopy, and electrochemistry. Plausible mechanisms for the formation of these products are also proposed. Molybdopterin mimic: The synthesis of bio-inspired fused pyranoquinoxaline dithiolene ligand qpdt2- is discussed in detail. The most important step was introduction of the dithiolene moiety by Pd-catalyzed carbon-sulfur coupling. Reactions of MoIVO complex (Bu4N)2[MoO(qpdt)2], which mimics the active site of Mo enzymes, with protons, oxygen, and isocyanides led to new reactions and products (see scheme).
