G. Heinisch et al., SYNTHESIS OF N-ARYL-N'-HETEROARYL-SUBSTITUTED UREA AND THIOUREA DERIVATIVES AND EVALUATION OF THEIR ANTICONVULSANT ACTIVITY, Archiv der pharmazie, 330(7), 1997, pp. 207-210
Starting from amino(di)azines and 2-chloro-6-methyl iso(thio)cyanate a
series of aryl-substituted urea and thiourea derivatives was prepared
and screened as potential antiepileptics. Among the new derivatives t
ested, only 2b and 3c exhibited adequate anticonvulsant effects, where
as 3d and 4d were found to be convulsants per se.
