The carbon signals of the 2-acylamino-4H-1,3,4-thiadiazino[5,6-b]quinoxalines 1a,b, 2-acylamino-4H-1,3,4-thiadiazino[5,6-b]quinoxaline 1,1-dioxides 2a,b, and 2-amino-4H-1,3,4-thiadiazino[5,6-b]quinoxaline 3 in deuteriodimethyl sulfoxide and in deuteriotrifluoroacetic acid were assigned by the nmr (HMBC, HMQC) spectroscopy. The comparison of the carbon chemical shifts in deuteriodimethyl sulfoxide with those in deuteriotrifluoroacetic acid clarified that compounds 1a, 1b, and 3 were deuterized at the N5-position in deuteriotrifluoroacetic acid, while the 1,1-dioxides 2a,b did not undergo the N5-deuteration in deuteriotrifluoroacetic acid.

The palladium(0)-catalysed coupling of 2-haloquinoxalines with functionally substituted alkynes, addition of one mol equivalent of bromine to the 2-alkynylquinoxalines thus produced and then reaction of the resulting dibromides with disodium trithiocarbonate produced 2-hydroxymethyl- and 2-(diethoxymethyl)thieno[2,3-b]quinoxalines. Addition of bromine to some 6-substituted-2-(3,3-diethoxypropyn-1-yl)quinoxalines gave pyrrolo[1,2-a]quinoxalines. Treatment of a 3-(1,2-dibromoalkenyl)quinoline, a 3-(1,2-dibromoalkenyl)pyrazine, and a 5-(1,2-dibromoalkenyl)-pyrimidine with disodium trithiocarbonate failed to induce thiophene ring formation.

Using a previously reported flexible alignment model we have designed, synthesized, and evaluated a series of compounds at the human histamine H 4 receptor (H4R) from which 2-(4-methyl-piperazin-l-yl)- quinoxaline (3) was identified as a new lead structure for H4R ligands. Exploration of the structure-activity relationship (SAR) of this scaffold led to the identification of 6,7-dichloro 3-(4-methylpiperazin-l-yl) quinoxalin-2(1H)-one (VUF 10214, 57) and 2-benzyl-3-(4-methyl-piperazin-l-yl) quinoxaline (VUF 10148, 20) as potent H4R ligands with nanomolar affinities. In vivo studies in the rat reveal that compound 57 has significant anti-inflammatory properties in the carrageenan-induced paw-edema model.
