Part I: Synthesis, cancer chemopreventive activity and molecular docking study of novel quinoxaline derivatives

The reaction of o-phenylene diamine and ethyl oxamate is reinvestigated and led to 3-aminoquinoxalin-2(1H)-one rather than benzimidazole-2-carboxamide as was previously reported. The structure of the obtained quinoxaline has been confirmed by X-ray. The anti-tumor activity of synthesized quinoxalines 1-21 has been evaluated by studying their possible inhibitory effects on Epstein-Barr virus early antigen (EBV-EA) activation induced by 12-O-tetradecanoylphorbol-13- acetate (TPA). Among the studied compounds 1-21, compounds 12, 8, 13, 18, 17 and 19, respectively, demonstrated strong inhibitory effects on the EBV-EA activation without showing any cytotoxicity and their effects being stronger than that of a representative control, oleanolic acid. Furthermore, compound 12 exhibited a remarkable inhibitory effect on skin tumor promotion in an in vivo two-stage mouse skin carcinogenesis test using 7,12-dimethylbenz[a]anthracene (DMBA) as an initiator and TPA as a promoter. The result of the present investigation indicated that compound 12 might be valuable as a potent cancer chemopreventive agent. Moreover, the molecular docking into PTK (PDB: 1t46) has been done for lead optimization of the aforementioned compounds as potential PTK inhibitors.

Synthesis and photochemical reaction of novel, visible-wavelength oxidizable polymerization sensitizer based on the 12H-quinoxalino[2,3-b][1,4]benzothiazine skeleton

Novel dyes based on the 12H-quinoxalino[2,3-b] [1,4]benzothiazine skeleton were synthesized and subsequently characterized using 1H NMR. Their electrochemical and spectral properties, such as absorption and emission spectra, quantum yield of fluorescence, and quantum yield of singlet oxygen formation, were measured. These compounds were evaluated as sensitizers for alkoxypyridinium salt photodecomposition, and the results are discussed on the basis of the free energy change for electron transfer from benzothiazine dyes to alkoxypyridinium compounds. Benzothiazine dyes are useful oxidizable sensitizers for N-alkoxypyridinium photoinitiators. The mechanism of the dye photobleaching is supported by time-dependent density functional theory (TD-DFT) calculations and the quantum yields of sensitized proton formation. Photoredox pairs consisting of benzothiazine dyes and alkoxypyridinium salt were found to be effective initiation systems for free radical polymerization of methyl acrylate and trimethylolpropane triacrylate (TMPTA) using visible light.

Metal catalyst free cyclization of 3-alkynyl substituted 2-(indol-3-yl)quinoxalines in TFA alone: a new synthesis of indolophenazines

TFA alone was found to be remarkably effective for the intramolecular hydroarylation (IMHA) of alkynes when employed as a solvent in the cyclization of 3-alkynyl substituted 2-(indol-3-yl)quinoxalines. This simple and metal free cyclization method afforded a range of indolophenazines as new and potential cytotoxic agents. The use of excess TFA was found to be crucial for the success of this reaction.

Fragment based design of new H4 receptor-ligands with anti-inflammatory properties in vivo

Using a previously reported flexible alignment model we have designed, synthesized, and evaluated a series of compounds at the human histamine H 4 receptor (H4R) from which 2-(4-methyl-piperazin-l-yl)- quinoxaline (3) was identified as a new lead structure for H4R ligands. Exploration of the structure-activity relationship (SAR) of this scaffold led to the identification of 6,7-dichloro 3-(4-methylpiperazin-l-yl) quinoxalin-2(1H)-one (VUF 10214, 57) and 2-benzyl-3-(4-methyl-piperazin-l-yl) quinoxaline (VUF 10148, 20) as potent H4R ligands with nanomolar affinities. In vivo studies in the rat reveal that compound 57 has significant anti-inflammatory properties in the carrageenan-induced paw-edema model.
