Cytotoxic activity of a series of heteroaryl-ONN-azoxy-sulphones and aryl sulphonylhydrazones.
Synthesis of heteroaryl-ONN-azoxysulphones and pyrazolyl-ONN-azoxycyanides was carried out by the action of the appropriate reagents on the corresponding nitroso derivatives. Pyrazolyl-ONN-azoxyamides were obtained by hydrolysis of the corresponding cyanides. Synthesis of the arylsulphonylhydrazones was carried out by reacting R-substituted phenyl-sulphonylhydrazines on the isomers of methylfuroxancarbaldehyde. Cytotoxic activity was assessed on HeLa cells. Some of the compounds tested inhibit the colony-forming ability of the tumor cells at low concentrations.
