In vitro cytotoxic activity of aryl and heteroaryl-ONN-azoxycyanides

Some aryl-N(O) = N-X and heteroaryl-N(O) = N-CN compounds were synthetized and tested against a culture of HeLa cells. The results obtained show that the - N(O) = N beta CN function, a new cytostatic group, is useful in the design of potential antitumoral compounds.
