Red-light-emitting system based on aggregation of donor-acceptor derivatives in polar aqueous media

Glowing together: An efficient red-light-emitting system has been created in polar water media based on the aggregation of donor-acceptor molecules. In the THF/water mixture, the emission was quenched when a small volume of water was used, whereas it was recovered and enhanced upon aggregate formation with a large water volume. Copyright

Present status of quinoxaline motifs: Excellent pathfinders in therapeutic medicine

Quinoxalines belong to a class of excellent heterocyclic scaffolds owing to their wide biological properties and diverse therapeutic applications in medicinal research. They are complementary in shapes and charges to numerous biomolecules they interact with, thereby resulting in increased binding affinity. The pharmacokinetic properties of drugs bearing quinoxaline cores have shown them to be relatively easy to administer either as intramuscular solutions, oral capsules or rectal suppositories. This work deals with recent advances in the synthesis and pharmacological diversities of quinoxaline motifs which might pave ways for novel drugs development.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Novel Antagonists of 5-HT3 Receptors. Synthesis and Biological Evaluation of Piperazinylquinoxaline Derivatives

A series of piperazinylquinoxalines has been synthesized and studied as 5-HT3 receptor antagonists in different preparations.Antagonism to 5-HT in the longitudinal muscle of the guinea pig ileum was particularly prominent in cyanoquinoxaline derivatives with an alkyl substituent on the piperazine moiety.The pA2 of some selected compounds against the 5-HT3 agonist 2-methyl-5HT in the guinea pig ileum was in the range of tropisetron or ondansetron, and one of them, 7e, was more potent than these reference compounds by approximately 2 or 3 orders of magnitude.However, these compounds were markedly less potent than either tropisetron or ondansetron as displacers of 3H-BRL 43694 binding to rat cortical membranes or as antagonists of the Bezold-Jarisch reflex in rats.Piperazinylcyanoquinoxalines represent a new class of 5-HT3 antagonists with a selective effect on guinea pig peripheral receptors.

FeCl3 catalysed 7-membered ring formation in a single pot: A new route to indole-fused oxepines/azepines and their cytotoxic activity

Various oxepine and azepine fused N-heterocyclic derivatives were synthesized using a new and one-pot reaction of 2,3-dichloro quinoxaline/pyrazine with 2-(1H-indol-2-yl)phenol/aniline in the presence of 25 mol% FeCl3. The reaction proceeded via C-C bond followed by C-X (X = O or N) bond formation to construct the central 7-membered ring, affording the desired products in good yields. The structure assignment was confirmed by the single crystal X-ray analysis of a synthesized oxepine fused N-heterocycle derivative. Most of the synthesized compounds were found to be promising when tested for their anti-proliferative properties against cervical and breast cancer cell lines.

Sensing of halogenated aromatic hydrocarbons in water with a cavitand coated piezoelectric device

A study leading to the development of a piezoelectric sensing device for environmental monitoring of aromatic micropollutants in water is reported. A Piezoelectric Quartz Crystal (PQC) was functionalized through electropolymerization of a quinoxaline cavitand, known to possess remarkable capabilities in selectively trapping aromatic compounds through multiple pi-pi and CH-pi interactions. The obtained film was characterized via X-ray Photoelectron spectroscopy (XPS) to elucidate its chemical composition. The design and synthesis of the new quinoxaline cavitand functionalized at the upper rim with a bithiophene moiety suitable for electropolymerization is described. The molecular structure of the new receptor was elucidated via X-ray diffraction analysis. The performance of the obtained sensor towards selected chlorinated and not chlorinated hydrocarbons in water was tested. Excellent limit of detection (0.17 ppm), below the present stringent Italian value, was achieved for 1,2,4-trichlorobenzene, outperforming conventional systems. The frequencymetric sensor showed high reproducibility from independent functionalized PQCs, with RSD values lower than 5%.

A novel efficient synthesis of 2-styryl-6(7)-bromothiazolo[4,5-b]quinoxaline based fluorescent dyes was achieved by the condensation of 2-alkyl-6(7)-bromothiazolo[4,5-b]quinoxaline with selected 4-N,N-dialkylamino-substituted arylaldehydes and heteroarylaldehydes in the presence of piperidine or acid anhydride. The colouristic, fluorophoric, and dyeing properties of these dyes were studied.
