Quinoxaline chemistry. Part 5. 2-(R)-benzylaminoquinoxalines as nonclassical antifolate agents. Synthesis and evaluation of in vitro anticancer activity

Thirty-one quinoxalines bearing a substituted benzylamino group on position 2 and various substituents on position 3, 6, 7 and 8 of the heterocycle were prepared in order to evaluate in vitro anticancer activity. Preliminary screening performed at NCl on twenty-two compounds showed that most derivatives exhibited a moderate to strong growth inhibition activity on various tumor panel cell lines between 10-5 and 10-4 molar concentrations. Interesting selectivities were also recorded between 10-8 and 10-5 M.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. 55686-94-7. Introducing a new discovery about 55686-94-7, Name is 2-Chloro-7-nitroquinoxaline

From simple quinoxalines to potent oxazolo[5,4-: F] quinoxaline inhibitors of glycogen-synthase kinase 3 (GSK3)

2,7-Disubstituted oxazolo[5,4-f]quinoxalines were synthesized from 6-amino-2-chloroquinoxaline in four steps (iodination at C5, substitution of the chloro group, amidation and copper-catalysed cyclization) affording 28 to 44% overall yields. 2,8-Disubstituted oxazolo[5,4-f]quinoxaline was similarly obtained from 6-amino-3-chloroquinoxaline (39% overall yield). For the synthesis of other oxazolo[5,4-f]quinoxalines, amidation was rather performed before substitution; moreover, time-consuming purification steps were avoided between the amines and the final products (38 to 54% overall yields). Finally, a more efficient method involving merging of the last two steps in a sequential process was developed to access more derivatives (37 to 65% overall yields). Most of the oxazolo[5,4-f]quinoxalines were evaluated for their activity on a panel of protein kinases, and a few 2,8-disubstituted derivatives proved to inhibit GSK3 kinase. While experiments showed an ATP-competitive inhibition on GSK3beta, structure-activity relationships allowed us to identify 2-(3-pyridyl)-8-(thiomorpholino)oxazolo[5,4-f]quinoxaline as the most potent inhibitor with an IC50 value of about 5 nM on GSK3alpha.
