A series of (Z)-2-(substituted aryl)-N-(3-oxo-4-(substituted carbamothioyl)-3,4-dihydro-2H-benzo[b][1,4]oxazin-7-yl) hydrazine carboxamides (6a-r) was synthesized using 2-amino-5-nitrophenol as a starting material. All the synthesized compounds possessed two hydrogen-bonding domains and their effect on the activity was studied thereof. The anticonvulsant activity was assessed by

Two hair dye components, carcinogenic 4-nitro-2-aminophenol and 5-nitro-2-aminophenol, induced Cu(II)-dependent DNA cleavage frequently at thymine and guanine residues in DNA fragments obtained from the c-Ha-ras-1 protooncogene. When the p53 tumor suppressor gene was used, 4-nitro-2-aminophenol caused Cu(II)-dependent piperidine-labile sites at
