Cross-conjugated alkylidene prostaglandins have been shown to be potent cytostatic agents that exert their action through a unique and unusual mechanism. Compounds in this class also inhibit viral replication and have a role in osteogenesis and adipogenesis; consequently, they are of considerable current interest as pharmaceutical lead compounds. The purpose of our research was to define an efficent
交叉缀合的亚烷基前列腺素已被证明是有效的细胞抑制剂,可通过独特而不同寻常的机制发挥作用。这类化合物还抑制病毒复制,并在成骨和脂肪形成中起作用。因此,它们作为药物先导化合物在当前具有相当大的意义。我们研究的目的是为标题中提及的C-10三氟甲基前列腺素的组装定义一种有效的方案。根据该系列中已知的结构-活性关系,预测该化合物显示出强大的抗肿瘤活性。描述了一种新颖的策略,用于通过离子电环过程组装在C-12处具有氧官能团的Delta(7)-不饱和前列腺素的碳骨架。合成的关键步骤是通过电环开环反应制备二烯酮14b和26a的离子电环化,从而形成官能化的碳骨架。发现目标化合物在体外对两种低M范围的人肿瘤细胞系具有细胞毒性,从而证实了我们的预测。
