  Total Synthesis of Natural and Unnatural Lamellarins with Saturated and Unsaturated D-Rings

  摘要：

  Twenty-eight natural and unnatural lamellarins with either a saturated or an unsaturated D-ring were synthesized according to our developed synthetic route. The key step involved the Michael addition/ring closure (Mi-RC) of the benzyldihydroisoquinoline and alpha-nitrocinnamate derivatives, which provided the 2-carboethoxypyrrole intermediates in moderate to good yields (up to 78% yield). Subsequent hydrogenolysis/lactonization furnished lamellarins with a saturated D-ring in excellent yields (up to 93% yield). DDQ oxidation of the saturated lamellarin acetates led directly to the corresponding unsaturated analogues in 54-95% yield. In addition, only two steps in our developed strategy require column chromatography.

  Despite the therapeutic potential of marine‐derived lamellarin natural products, their preclinical development has been hampered by their lipophilic nature, causing very poor aqueous solubility. In order to develop more drug‐like analogs, their structure was streamlined in this study from both the cytotoxic activity and lipophilicity standpoints. First, a modified total synthetic route was successfully

  尽管海洋来源的lamellarin天然产物具有治疗潜力，但其亲脂性质阻碍了它们的临床前开发，导致水溶性很差。为了开发更多类似药物的类似物，本研究从细胞毒性活性和亲脂性的角度简化了它们的结构。首先，成功设计了一条改良的总合成路线来构建59个系统设计的lamellarin类似物的文库，然后对其进行细胞毒性和log P测定。连同先前在我们实验室中合成的25种第一代薄片蛋白，对结构-活性和结构-亲脂性之间的关系进行了广泛的评估。我们的结果清楚地表明了层状蛋白骨架周围的其他结构要求，
