these compounds as drug candidates for cancer treatment. In the current work, we report the synthesis of new diosgenin oxime derivatives as potential antiproliferative agents. From (25 R)-5α-spirost-3,5,6-triol (1), a diosgenin derivative, ketones 2, 3, 4, and 9 were obtained and used as precursors of the new oximes. A condensation reaction was carried out between the steroidal ketones (2, 3, 4, and 9)
最近的研究证明了氮杂类固醇和类固醇皂苷元对人类癌细胞系的抗增殖和细胞毒性作用。科学界对这些化合物作为癌症治疗候选药物越来越感兴趣。在目前的工作中,我们报告了新的薯蓣皂苷元肟衍生物的合成作为潜在的抗增殖剂。从 (25 R)-5α-spirost-3,5,6-三醇 (1)(一种薯蓣皂苷元衍生物)中获得酮 2、3、4 和 9,并将其用作新肟的前体。甾体酮(2、3、4和9)与盐酸羟胺在2,4,6-三甲基吡啶中进行缩合反应,生成五种螺甾烷肟(其中四种以前未报道过),分子量为42-96 % 屈服。此外,使用亚硫酰氯通过贝克曼断裂合成了一种新的螺甾烷α,β-不饱和氰酮,产率62%。此外,我们提出了一种反应机制,旨在解释这种转变。
