peculiar 3D orientation of these substituents is able to reproduce the hydrophobic side chains in LxxLL-like protein recognition motifs. Biological results showed altered p53 expression and nuclear translocation in cells sensitive to the compounds, suggesting p53 involvement in their anticancer mechanism of action. Unfortunately, because of poor solubility of the active analogues, it was not possible
新型四取代吡咯衍生物8g,8h和8i在低微摩尔浓度下显示出针对M14黑色素瘤细胞的选择性细胞毒性。结构-活性关系(SAR)表明,吡咯核心上存在三个芳族取代基,这是生物活性所必需的。计算研究强烈表明,这些取代基的特殊3D方向能够复制LxxLL样蛋白识别基序中的疏水侧链。生物学结果表明,对化合物敏感的细胞中p53表达和核易位改变,表明p53参与了其抗癌作用机制。不幸的是,由于活性类似物的溶解性差,不可能通过NMR技术进行进一步的研究。生成了药理学模型,并将其用于在分子数据库中执行3D搜索。
