Abstract
A novel class of azo-guanidine compounds is introduced in this article. The novel compound 2-(2-hydroxyphenyl)-1-(phenylamino)-3-(phenylimino)guanidine (AG) was synthesized and well characterized by using different analytical instrumental techniques like elemental analysis, FTIR, (1)H and (13)C NMR, UV-Visible spectroscopy and cyclic voltammetry. The new compound was found interacting with DNA and shows clear color change in the solution. The AG-DNA complex was qualitatively and quantitatively characterized with UV-Visible spectroscopy and cyclic voltammetry. Electrostatic mode of interaction, clear color change and moderate binding constant (K(b)=10(4)) indicate its potential use as DNA staining agent.

Abstract
A series of novel N-substituted indophenazine derivatives were synthesised and screened for antiviral activity against a panel of human pathogenic viruses. New compounds were synthesised through modifying the N-hydrogen of indophenazine moiety with different substitution and formaldehyde by Mannich reaction. The structure of the synthetic compounds was characterised by means of infra red and nuclear magnetic resonance spectral data. The compound 10H-indolo-2-Amino pyridine [3,2-b] quinoxalines inhibits Herpes simplex virus-1 and vaccinia virus at a concentration of 12 μg/ml, and the cytotoxicy was found to be 100 μg/ml. 4-Aminobenzene sulfonamide-10H-indolo [3,2-b] quinoxalines inhibit vaccinia virus at a concentration of 12 μg/ml and cytotoxicy was found to be 100 μg/ml. The anti-HIV activities of the new compounds were also screened for in vitro antiviral activity against replication of HIV-1 (IIIB) and HIV-2 (ROD) in MT-4 cells using zidovudine (AZT) as standard. Pthalimide derivative inhibited the replication of HIV-2 (EC50=11.60 μg/ml and CC50=61.63 μg/ml) in MT-4 cells.

Pyrrolo[2,3-b]quinoxalines as inhibitors of firefly luciferase: their Cu-mediated synthesis and evaluation as false positives in a reporter gene assay. Bioorg Med Chem Lett 2012; 22:6433-41.

Abstract
2-Substituted pyrrolo[2,3-b]quinoxalines having free NH were prepared directly from 3-alkynyl-2-chloroquinoxalines in a single pot by using readily available and inexpensive methane sulfonamide (or p-toluene sulfonamide) as an ammonia surrogate. The reaction proceeded in the presence of Cu(OAc)(2) affording the desired product in moderate yield. The crystal structure analysis of a representative compound and its supramolecular interactions are presented. Some of the compounds synthesized exhibited inhibitory activities against luciferase that was supported by the predictive binding mode of these compounds with luciferase enzyme through molecular docking studies. The key observations disclosed here can alert users of luciferase reporter gene assays for possible false positive results due to the direct inhibition of luciferase.

Abstract
New 7-(2-aminoethyl)-7H-benzo[4,5]indolo[2,3-b]quinoxalines (13-20) were synthesized with high yields starting from 3H-benzo[e]indole-1,2-dione. These compounds were screened for the cytotoxicity, anti-viral activity, interferon inducing ability and DNA affinity compared with the corresponding 6-(2-aminoethyl)-6H-indolo[2,3-b]quinoxaline derivatives (1-12). It was shown, that compounds 13-20 bind to DNA stronger (lg Кa=6.23-6.87) than compounds 1-12 (lg Кa=5.57-5.89). Anti-viral activity is significantly reduced with annulations of benzene ring in Indoloquinoxaline moiety 13-20.

Abstract
In the pathway of anticancer drug development, we designed and synthesized some 6H-indolo[2,3-b]quinoxaline derivatives (which act as DNA intercalators) by structural modification. The structure of the 6H-indolo[2,3-b]quinoxaline derivatives was confirmed by IR, NMR, Mass and elemental analysis. The compounds (IDQ-5, IDQ-10, IDQ-11, IDQ-13, and IDQ-14) exhibited significant in vitro activity against a human leukemia (HL-60) cell line. The QSAR derived for modeling the cytotoxic activity of 6H-indolo[2,3-b]quinoxaline derivatives suggests that candidate structures for increased cytotoxic potency should incorporate cyclic substituents or substituents with primary carbon atoms.

Abstract
Two isomers were isolated during the reaction between 3-methyl-quinoxalin-2-one and bis-(2-chloro-ethyl)amine hydro-chloride. The crystal structure of one isomer has already been reported [Caleb, Bouhfid, Essassi & El Ammari (2009). Acta Cryst. E65, o2024-o2025], while that of the second isomer is the subject of this work. The title compound, C(14)H(15)N(3)O(3), has a new structure containing oxazolidine and quinoxaline rings linked by an eth-oxy group. The main difference between the two isomers is the position of the oxazolidine group with respect to the quinoxaline system. The dihedral angle between the fused planar rings and the oxazolidin-2-one ring is 41.63 (8)° in the title mol-ecule.
