In heterogeneous catalysis, the catalyst is in a different phase from the reactants. HPLC of Formula: C8H8N2O, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 59564-59-9, name is 3,4-Dihydroquinoxalin-2(1H)-one. In an article£¬Which mentioned a new discovery about 59564-59-9
Quinoxalin-2(1H)-one derived AMPA-receptor antagonists: Design, synthesis, molecular docking and anticonvulsant activity
A new series of 4-acetyl-1-substituted-3,4-dihydroquinoxalin-2(1H)-ones (3?14) were designed and synthesized in order to evaluate their alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA)-receptor antagonism as a proposed mode of their anticonvulsant activity. The structure of the synthesized compounds was confirmed by elemental analysis and spectral data (infrared, 1H nuclear magnetic resonance (NMR), 13CNMR, and mass). The molecular design was performed for all synthesized compounds to predict their binding affinity towards AMPA-receptor in order to rationalize their anticonvulsant activity in a qualitative way and explain the possible interactions that might take place between the tested derivatives and AMPA receptor in comparing to compounds III and YM872 in order to obtain the anticonvulsant effect. The data obtained from the molecular modeling was strongly correlated with that obtained from the biological screening which revealed that; compounds 14b, 14a, and 13b showed the highest binding affinities toward AMPA-receptor and also showed the highest anticonvulsant activities against pentylenetetrazole-induced seizures in experimental mice. The relative potencies of these compounds were 1.89, 1.83, and 1.51 respectively, in comparing to diazepam.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 59564-59-9, help many people in the next few years.HPLC of Formula: C8H8N2O
