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 1H-NMR, 13C-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.
通过芳基磺酰氯与不同的氰基乙酰胺基肟的反应制备了一系列新型氰基肟基磺酸盐衍生物,范围从最简单的未取代酰胺到含有 N-乙基(模仿 Oxyma 模板)、N-哌啶基和 N-吗啉基链的类似物。此外,氰基肟、N-羟基苯甲亚胺基氰化物和N-羟基吡啶亚胺基氰化物也被用于合成新型氰基肟基磺酸盐衍生物。所制备的化合物的结构通过1H-NMR、13C-NMR和元素分析进行了确认。初步生物测定表明,一些标题化合物,如 2-oxo-2-(piperidin-1-yl)-N-(tosyloxy)acetimidoyl colonide (TsPipOx)、N-(tosyloxy)benzimidoyl colonide (TsPhOX)、N -(萘-2-基磺酰氧基)-2-氧代-2-(哌啶-1-基)乙酰亚氨基氰化物(NpsPipOx)、2-氨基-N-(萘-2-基磺酰氧基)-2-氧代乙酰亚氨基氰化物(NpsAmOx)、 N-(萘-2-基磺酰氧基)苯并亚胺酰氰化物 (NpsPhCN) 和 N-(萘-2-基磺酰氧基)吡啶亚胺酰氰化物 (NpsPyCN) 对小鼠成纤维细胞 L929 显示出抗增殖作用。计算出的 IC50 值范围在 36.5μg/mL 至 0.235mg/mL 之间。然而,抗增殖作用似乎是细胞抑制作用而不是细胞毒性作用。这些化合物只会最大限度地减少生长活性,而不会完全杀死细胞。
