Synthesis of 2-Substituted Indoles through Visible Light-Induced Photocatalytic Cyclizations of Styryl Azides

A visible light-induced photocatalytic intramolecular cyclization of styryl azides has been developed in the presence of the ruthenium complex Ru(bpy)3Cl2 (0.5 mol%) as photocatalyst at room temperature. The present photocatalytic strategy features operational simplicity as well as high functional group tolerance, and provides a facile access to various 2-substituted N-free indoles in good to excellent yields. Importantly, the present process can employ sunlight as the light source to afford the corresponding products without loss of reaction efficiency.

Design, synthesis and molecular docking study of novel quinoxalin-2(1H)-ones as anti-tumor active agents with inhibition of tyrosine kinase receptor and studying their cyclooxygenase-2 activity

On continuation to our work, new quinoxalin-2(1H)-ones were synthesized to study their cytotoxic effect against HepG-2 and MCF-7 with their effect on the human tyrosine kinase (TRK). Compounds 12, 18, 15, 13, 11a, 20 and 16, respectively, were found to be more potent than cisplatin against HepG2 and selective to TRK. Also, compounds 12, 18, 20, 13, 14, and 22, respectively, exhibited decidedly activity against MCF- 7 and selectivity against human TRK compared to cisplatin. A molecular docking study was also performed to gain comprehensive understanding into plausible binding modes and to conclude the structure activity relationships of the synthesized compounds. Moreover, anti-inflammatory activity was studied. Compounds 12, 15, 18 and 22 were found to be potent and selective against COX-2.

Structure?activity relationship study of DEL-22379: ERK dimerization inhibitors with increased safety

Abstract: Aberrant activation of ERK signaling pathway usually leads to oncogenesis, and small molecular agents targeting this pathway are impeded by the emergence of drug resistance due to reactivation of ERK signaling. Compound DEL-22379 has been reported to inhibit ERK dimerization which was unaffected by drug-resistant mechanism reactivating the ERK signaling. Here, we discussed a structure?activity relationship study of DEL-22379. Forty-seven analogues were designed and synthesized. Each synthesized compound was biologically evaluated for their inhibitory rates on several tumor cell lines and compounds with high inhibitory rates were further evaluated for IC50 values. The structure?activity relationship of idolin-2-one scaffold and the impact of Z/E configuration on potency were discussed. Potential safety of two synthesized analogues was investigated and in silico docking study of five compounds was performed to understand the structural basis of ERK dimerization inhibition.

Survey of the electrochemical behavior of chlorinated pyrazines, quinoxalines, and pyridazines at carbon and mercury cathodes

Cyclic voltammetry and controlled-potential electrolysis have been employed to examine the electrochemical behavior of some mono- and dichlorinated pyrazines, quinoxalines, and pyridazines at carbon and mercury cathodes in either acetonitrile or dimethylformamide containing a tetraalkylammonium salt. Unsubstituted pyrazine and pyridazine each exhibit a single reduction wave, whereas unsubstituted quinoxaline shows three cathodic waves. For the chlorinated compounds, an additional wave is seen for the reduction of each carbon-chlorine bond. Depending on the potential of the cathode, bulk electrolyses of dichlorinated pyrazines or quinoxalines afford either the monochlorinated or fully dechlorinated product, whereas the monochlorinated analogues undergo reduction to the dechlorinated species. Electrolyses of chlorinated pyridazines give dark colored solutions, but the products (apparently polymeric) cannot be detected or identified by means of conventional GC, GC-MS, and HPLC techniques.
