Abstract:

A series of novel cyano oximino sulfonate derivatives were prepared from the reaction of arylsulfonyl chloride with different cyanoacetamide-based oximes ranging from the simplest unsubstituted amide to analogues containing N-ethyl (mimicking the Oxyma template), N-piperidinyl and N-morpholinyl chains. In addition, the cyano oximes, N-hydroxybenzimidoyl cyanide and N-hydroxypicolinimidoyl cyanide were also used in the synthesis of the novel cyano oximino sulfonate derivatives. The structures of the prepared compounds were confirmed by (1)H-NMR, (13)C-NMR, and elemental analysis. The preliminary bioassays showed that some of the title compounds, such as 2-oxo-2-(piperidin-1-yl)-N-(tosyloxy)acetimidoyl cyanide (TsPipOx), N-(tosyloxy)benzimidoyl cyanide (TsPhOX), N-(naphthalen-2-ylsulfonyloxy)-2-oxo-2-(piperidin-1-yl)acetimidoyl cyanide (NpsPipOx), 2-amino-N-(naphthalen-2-ylsulfonyloxy)-2-oxoacetimidoyl cyanide (NpsAmOx), N-(naphthalen-2-ylsulfonyloxy)benzimidoyl cyanide (NpsPhCN), and N-(naphthalen-2-ylsulfonyloxy)picolinimidoyl cyanide (NpsPyCN), showed anti-proliferation effect on the mouse fibroblast L929. The calculated IC50-values were ranging between 36.5 µg/mL and 0.235 mg/mL. However the anti-proliferation effects seem to be cytostatic rather than cytotoxic. The compounds only minimize the growth activity without completely killing the cells.
