A novel series of quinoxalinediones possessing imidazolyl and related heteroaromatic substituents was synthesized and evaluated for their activity to inhibit [3H]AMPA binding from rat whole brain. From the structure- activity relationships, it was found that the 1H-imidazol-1-yl moiety could function as a bioisostere for the cyano and nitro groups, and that 6-(1H- imidazol-yl)-7-nitro-2,3(1H,4H)-quinoxalinedione (11) showed the most potent activity for the AMPA receptor. Compound 11 was evaluated for selectivity versus other excitatory amino acid receptors, and its action against AMPA at its receptor in the rat striatum was characterized. These data showed that compound 11 was a selective antagonist for the AMPA receptor with a K(i) value of 0.084 muM, being approximately equipotent with 2,3-dihydro-6-nitro- 7-sulfamoylbenzo(f)quinoxaline (3) (NBQX; K(i) = 0.060 muM). Compound 11 was also found to give protection against sound-induced seizure on DBA/2 mice at the minimum effective dose of 3 mg/kg ip (3; 10 mg/kg ip).

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Computed Properties of C8H4Cl2N2, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 2213-63-0, Name is 2,3-Dichloroquinoxaline, molecular formula is C8H4Cl2N2

Toll-like receptor (TLR) 7 and 8 agonists are potential vaccine adjuvants, since they directly activate APCs and enhance Th1-driven immune responses. Previous SAR investigations in several scaffolds of small molecule TLR7/8 activators pointed to the strict dependence of the selectivity for TLR7 vis–vis TLR8 on the electronic configurations of the heterocyclic systems, which we sought to examine quantitatively with the goal of developing heuristics to define structural requisites governing activity at TLR7 and/or TLR8. We undertook a scaffold-hopping approach, entailing the syntheses and biological evaluations of 13 different chemotypes. Crystal structures of TLR8 in complex with the two most active compounds confirmed important binding interactions playing a key role in ligand occupancy and biological activity. Density functional theory based quantum chemical calculations on these compounds followed by linear discriminant analyses permitted the classification of inactive, TLR8-active, and TLR7/8 dual-active compounds, confirming the critical role of partial charges in determining biological activity.

Abstract: Many shreds of evidence have recently correlated A2B receptor antagonism with anticancer activity. Hence, the search for an efficient A2B antagonist may help in the development of a new chemotherapeutic agent. In this article, 23 new derivatives of [1,2,4]triazolo[4,3-a]quinoxaline were designed and synthesized and its structures were confirmed by different spectral data and elemental analyses. The results of cytotoxic evaluation of these compounds showed six promising active derivatives with IC50 values ranging from 1.9 to 6.4 muM on MDA-MB 231 cell line. Additionally, molecular docking for all synthesized compounds was performed to predict their binding affinity toward the homology model of A2B receptor as a proposed mode of their cytotoxic activity. Results of molecular docking were strongly correlated with those of the cytotoxic study. Finally, structure activity relationship analyses of the new compounds were explored.

Suzuki-Miyaura cross-coupling reaction with 2-heteroarylboronic acids is generally challenging due to these acids easy decomposition. To overcome this problem, we developed a coupling method that uses 2-heteroaryl pinacol boronates in the presence of 1.0 mol % Pd(OAc)2 and 2.0 mol % S-Phos with 4 equiv amount of LiOH in dioxane and H2O at 80 C for 30 min. This developed method allowed for the synthesis of a wide variety of 2-heteroaryl pyrimidines from 2-chloropyrimidyl derivatives in high yields, and is also useful in the preparation of various biaryl derivatives from heteroaryl chlorides.
