A series of 1,2-benzo-3-phenoxazone also known as 5H-benzo[a]phenoxazin-5-one (1a-1c) were synthesized and characterized by 1- and 2-D nmr, mass spectrometry and computer simulation on readily available, inexpensive software. It is proposed that these molecules intercalated in GC rich DNA regions and that internal hydrogen bonding caused by a molecule of water in the salt will help to anchor these actinomycin D-like antibiotic into these locations.
