hydroxylamine hydrochloride and sodium acetate. Ten analogues of 5a, namely 5b-5k, were prepared and evaluated for cytotoxicity. Six of the 11 compounds in series 5, as well as 1, showed activity in the 240-950 microM range against murine mammary EMT6 cells. Series 5 was also examined for cytotoxicity in an in vitro screen conducted by the National Cancer Institute with approximately 54 cell lines, and
2,6-双-(苯基亚甲基)环己酮(1)与4摩尔过量的羟胺盐酸盐和乙酸钠反应生成相应的肟2,生成2-(α-羟基氨基-α-苯基甲基)-6-苯基亚甲基环己酮一肟(5a),其结构由高分辨率质子核磁共振波谱推导,并通过X射线分析证实。最终由1与羟胺本身而不是由盐酸羟胺和乙酸钠的混合物制备化合物2。制备了10a的5a类似物,即5b-5k,并评估了细胞毒性。第5系列和11系列的11种化合物中有6种在240-950 microM范围内具有抗鼠乳腺EMT6细胞的活性。
