We screened 1434 small heterocyclic molecules and identified thirteen 2,3,6-trisubstituted quinoxaline derivatives that were able to inhibit the Wnt/beta-catenin signal pathway and cell proliferation. In the screen, some of the hit compounds such as the ethylene group-coupled quinoxaline derivatives were shown to hold promise for use as potential small-molecule inhibitors of the Wnt/beta-catenin signal pathway in non-small-cell lung cancer cell lines.

Nonstructural protein 5A (NS5A) represents a novel target for the treatment of hepatitis C virus (HCV). Daclatasvir, recently reported by Bristol-Myers-Squibb, is a potent NS5A inhibitor currently under investigation in phase 3 clinical trials. While the performance of daclatasvir has been impressive, the emergence of resistance could prove problematic and as such, improved analogues are being sought. By varying the biphenyl-imidazole unit of daclatasvir, novel inhibitors of HCV NS5A were identified with an improved resistance profile against mutant strains of the virus while retaining the picomolar potency of daclatasvir. One compound in particular, methyl ((S)-1-((S)-2-(4-(4-(6-(2-((S)-1-((methoxycarbonyl)-L-valyl)pyrrolidin-2-yl) -1H-imidazol-5-yl)quinoxalin-2-yl)phenyl)-1H-imidazol-2-yl)pyrrolidin-1-yl) -3-methyl-1-oxobutan-2-yl)carbamate (17), exhibited very promising activity and showed good absorption and a long predicted human pharmacokinetic half-life. This compound represents a promising lead that warrants further evaluation. Resisting resistance: An investigation into the anti-hepatitis C virus (HCV) replicon activity of a series of biaryl-linked pyrrolidine NS5A inhibitors explored a diverse range of core structure modifications as key determinants of antiviral activity and susceptibility to common resistance mutations. Further evaluation of several core structure designs identified a compound with excellent pharmacokinetics, suitable for once daily dosing.

Quality Control of 2-Chloro-7-nitroquinoxaline, New Advances in Chemical Research in 2021. The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 55686-94-7, Name is 2-Chloro-7-nitroquinoxaline, molecular formula is C8H4ClN3O2.

2-{4-[(7-Chloro-2-quinoxalinyl)oxy]phenoxy}propionic acid (XK469) is among the most highly and broadly active antitumor agents to have been evaluated in our laboratories and is currently scheduled to enter clinical trials in 2001. The mechanism or mechanisms of action of XK469 remain to be elaborated. Accordingly, an effort was initiated to establish a pharmacophore hypothesis to delineate the requirements of the active site, via a comprehensive program of synthesis of analogues of XK469 and evaluation of the effects of structural modification(s) on solid tumor activity. The strategy formulated chose to dissect the two-dimensional parent structure into three regions – I, ring A of quinoxaline; II, the hydroquinone connector linkage; and III, the lactic acid moiety – to determine the resultant in vitro and in vivo effects of chemical alterations in each region. Neither the A-ring unsubstituted nor the B-ring 3-chloro-regioisomer of XK469 showed antitumor activity. The modulating antitumor effect(s) of substituents of differing electronegativities, located at the several sites comprising the A-ring of region I, were next ascertained. Thus, a halogen substituent, located at the 7-position of a 2-{4-[(2-quinoxalinyl)oxy]phenoxy}propionic acid, generated the most highly and broadly active antitumor agents. A methyl, methoxy, or an azido substituent at this site generated a much less active structure, whereas 5-, 6-, 8-chloro-, 6-, 7-nitro, and 7-amino derivatives all proved to be essentially inactive. When the connector linkage (region II) of 1 was changed from that of a hydroquinone to either a resorcinol or a catechol derivative, all antitumor activity was lost. Of the carboxylic acid derivatives of XK469 (region III), i.e., CONH2, CONHCH3, CON(CH3)2, CONHOH, CONHNH2, CN, or CN4H (tetrazole), only the monomethyl- and N,N-dimethylamides proved to be active.
