In continuation of our previous work on the design and synthesis of topoisomerase II (Topo II) inhibitors and DNA intercalators, a new series of quinoxaline derivatives were designed and synthesized. The synthesized compounds were evaluated for their cytotoxic activities against a panel of three cancer cell lines (Hep G-2, Hep-2, and Caco-2). Compounds 18b, 19b, 23, 25b, and 26 showed strong potencies against all tested cell lines with IC50 values ranging from 0.26 ± 0.1 to 2.91 ± 0.1 muM, comparable with those of doxorubicin (IC50 values ranging from 0.65 ± 0.1 to 0.81 ± 0.1 muM). The most active compounds were further evaluated for their Topo II inhibitory activities and DNA intercalating affinities. Compounds 19b and 19c exhibited high activities against Topo II (IC50 = 0.97 ± 0.1 and 1.10 ± 0.1 muM, respectively) and bound the DNA at concentrations of 43.51 ± 2.0 and 49.11 ± 1.8 muM, respectively, whereas compound 28b exhibited a significant affinity to bind the DNA with an IC50 value of 37.06 ± 1.8 muM. Moreover, apoptosis and cell-cycle tests of the most promising compound 19b were carried out. It was found that 19b can significantly induce apoptosis in Hep G-2 cells. It has revealed cell-cycle arrest at the G2/M phase. Moreover, compound 19b downregulated the Bcl-2 levels, indicating its potential to enhance apoptosis. Furthermore, molecular docking studies were carried out against the DNA?Topo II complex to examine the binding patterns of the synthesized compounds.

The anti-quorum and DNA cleaving agent is directed to a ruthenium complex formulated from dichloro-(eta6-p-cymene) ruthenium(II) dimer and 2-chloroquinoxaline, the complex having the formula: The reaction cleaves the dimer, leaving a half-sandwich ruthenium complex with an eta6 coordination bond to the arene ligand and an Ru?N bond attaching the chloroquinoxaline to the ruthenium complex. The agent has an anti-quorum sensing effect on bacteria, inhibiting the formation of biofilm and inhibiting bacterial virulence. The agent also binds to DNA and may cleave the DNA, e.g., at the N7 base pair of guanine, due to a hydrolytic mechanism, suggesting potential use as an anticancer or antitumor agent.

Telomeric regions containing G-quadruplex (G4) structures play a pivotal role in the development of cancers. The development of specific binders for G4s is thus of great interest in order to gain a deeper understanding of the role of these structures, and to ultimately develop new anticancer drug candidates. For several years, RuII complexes have been studied as efficient probes for DNA. Interest in these complexes stems mainly from the tunability of their structures and properties, and the possibility of using light excitation as a tool to probe their environment or to selectively trigger their reaction with a biological target. Herein, we report on the synthesis and thorough study of new RuII complexes based on a novel dipyrazino[2,3-a:2?,3?-h]phenazine ligand (dph), obtained through a Chichibabin-like reaction. Luminescence experiments, surface plasmon resonance (SPR), and computational studies have demonstrated that these complexes behave as selective probes for G-quadruplex structures.

The development of very high affinity, selective, and bioavailable h5-HT2A receptor antagonists is described. By investigation of the optimal position for the basic nitrogen in a series of 2-phenyl-3-piperidylindoles, it was found that with the basic nitrogen at the 3-position of the piperidine it was not necessary to further substitute the piperidine in order to obtain good binding at h5-HT2A receptors. This meant the compounds no longer had high affinity at the IKr potassium channel, an issue with previous series of 2-aryl-3-(4-piperidyl)indoles. Improvements could be made to oral bioavailability in this series by reduction of the pKa of the basic nitrogen, by adding a fluorine atom to the piperidine ring, leading to 3-(4-fluoropiperidin-3-yl)-2-phenyl-1H-indole (17). Metabolic studies with this compound identified oxidation at the 6-position of the indole as a major route in vitro and in vivo in rats. Blocking this position with a fluorine atom led to 6-fluoro-3-(4-fluoropiperidin-3-yl)-2-phenyl-1H-indole (22), an antagonist with 0.06 nM affinity for h5-HT2A receptors, with bioavailability of 80% and half-life of 12 h in rats.

AlCl3 facilitated C-N bond forming reaction between 2,3-dichloroquinoxaline and anilines affording a convenient method for the preparation of N-aryl substituted 3-chloroquinoxalin-2-amines. A related N-benzyl derivative, however, was prepared via a conventional method. These N-alkyl/aryl substituted 3-chloroquinoxalin-2-amines on coupling with terminal alkynes in toluene under Pd/C-Cu catalysis afforded a range of 1,2-disubstituted pyrrolo[2,3-b]quinoxalines within 3-5 h in good to excellent yields. Some of the compounds synthesized showed promising anti-proliferative properties when tested in vitro against two cancer cell lines. Docking studies indicated that these molecules interact well with human Akt in silico.
