A series of new 2,7-diamino-9-(N-substituted phenyl)-9,10-dihydro-1,8,9-triaza-anthracene-3,6- dicarbonitriles 6a-d were prepared by condensation of malononitrile with 2,6-diamino derivatives 5a-d which have been prepared by the action of sodium dithionite on 2,6-diazido-1-(N-substituted phenyl)-1,4-dihydropyridine-3,5- dicarbaldehydes 4a-d which in turn were prepared by the treatment of sodium azide with 3a-d. The structures of the newly synthesized compounds have been confirmed on the basis of elemental analysis and spectral studies. The newly synthesized title compounds have been screened for their in vitro antimicrobial activities. Some of the compounds exhibited encouraging results.
