Various dual inhibitors of COX-2 and 5-LOX enzymes have been developed so far in order to obtain more effective and safer anti-inflammatory drugs. The aim of this study was to design and synthesize new dual COX-2 and 5-LOX inhibitors, and to evaluate their enzyme inhibition potential and redox properties. Thirteen compounds (1–13) were designed taking into account structural requirements for dual COX-2

The synthesis of some novel 3,3,5,7-tetranitrooxindoles and 4,4-dinitropyrazol-5-ones and their behaviour towards various nucleophiles and electrophiles are reported. Reactions with hydroxide ions or secondary amines produced salts of e.g. 2-amino-3,5-dinitrophenyldinitromethane, which subsequently could be further transformed into indazoles, indoles or benzoxazinones depending upon substrate and conditions
