A straightforward synthesis of a group of 4-alkylamino-6-nitroquinolines st
arting from a common intermediate, 5,8-dimethoxy-6-nitro-4(1H)quinolone (3)
under bar, is described. These compounds were tested in vitro as potential
anti-trypanosomal agents. Some derivatives were found to have a significan
t activity, but less efficient than the control drug.
