An efficient synthesis of trialkyl (E)-3-(3-Oxo-2-3,4-dihydro-2-(1H)-quinoxalinylidene)-prop-1-ene-1,2,3-tricarboxylate derivatives via a simple three-component reaction between benzene-1,2-diamines with dialkyl acetylenedicarboxylates in the presence of K2CO3-PEG catalytic system at 100 oC was reported. The desired products were obtained in excellent yields (88-92%). Various benzene-1,2-diamin...

introduction: chemokines are low molecular weight proteins (8-17kda) with the main role of immune cells recruitment to injured tissues. ip-10/mob-1 is a cxc chemokine and different cell systems in response to external stimulation produce this chemokine. various signaling pathways are used by cell and tissue systems to regulate production of proteins e.g. chemokines. therefore we have investigat...
