Electric Literature of 1448-87-9, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 1448-87-9, 2-Chloroquinoxaline, introducing its new discovery.

Thirty compounds possessing quinoxaline structure bearing either substituted arylmethylmercapto-, arylmethylsulfinyl group or a piperazinyl moiety in position 2 were prepared in order to evaluate an antiulcer and gastroprotective activity in rat pylorus ligature, in comparison with omeprazole and ranitidine at the dose of 100 mg/kg after oral administration. Among the compounds of the first group one third showed a moderate activity being about half potent as omeprazole whereas in the second group compound 5b exhibited an activity superior to that of ranitidine accompanied with the lowest incidence of lesions and mortality and another compound (5i) was equiactive as ranitidine.

New series of [1,2,4]triazolo [4,3-a]quinoxaline and bis([1,2,4]triazolo)[4,3-a:3?,4?-c]quinoxaline derivatives have been designed, synthesized and biologically evaluated for their cytotoxic activities against three tumor cell lines (HePG-2, Hep-2 and Caco-2). Compounds 16e, 21, 25a and 25b exhibited the highest activities against the examined cell lines with IC50 values ranging from 0.29 to 0.90 muM comparable to that of doxorubicin (IC50 ranging from 0.51 to 0.73 muM). The most active members were further evaluated for their topoisomerase II (Topo II) inhibitory activities and DNA intercalating affinities as potential mechanisms for their anti-proliferative activities. Interestingly, the results of Topo II inhibition and DNA binding assays were consistent with that of the cytotoxicity data, where the most potent anti-proliferative derivatives exhibited good Topo II inhibitory activities and DNA binding affinities, comparable to that of doxorubicin. Moreover, the most active compound 25a caused cell cycle arrest at G2/M phase and induced apoptosis in Caco-2 cells. In addition, Furthermore, molecular docking studies were performed for the novel compounds against DNA-Topo II complex to investigate their binding patterns. Based on these studies, it was concluded that DNA binding and/or Topo II inhibition may contribute to the observed cytotoxicity of the synthesized compounds.

Oligomers of human islet amyloid polypeptide (h-IAPP) are believed to be the pathogenic species for type 2 diabetes mellitus. Peptide-cleaving agents selective for oligomers of h-IAPP were synthesized by using quinoxaline derivatives as recognition sites attached to the Co(III) complex of cyclen in this study. When the initial concentration of h-IAPP was lowered from 4.0 to 0.20 lM cleavage yield of the new agents was enhanced by 3 times reaching 16-22 mol %. This shows that the agents would have significant activities at subnano molar concentrations if the concentration of h-IAPP is lowered to the in vivo values. This further indicates that the peptide-cleaving agents prepared previously in this laboratory possess sufficiently high activity for application as a new therapeutic option for Alzheimer’s disease, type 2 diabetes mellitus, and Parkinson’s disease.
