在这项工作中,我们执行了一种通用的合成策略来获得新的吲哚内酰胺生物碱,这是蛋白激酶c的激动剂。该方案允许最有效的吲哚内酰胺V (ILV)立体异构体的合成,同时也提供了天然产物(-)-ILV的大规模生产。对这些化合物进行了结构活性研究,以阐明促进pkc介导的细胞反应所需的元件。白血病和淋巴瘤细胞系中ec50的测定以及与PKCδ C1B结构域的分子对接分析为这些研究提供了基础。发现了蛋白的体外活性与大环内酰胺环的构象之间的明显相关性,这可以指导针对PKC调节结构域的治疗设计工作。
In this work, we execute a general synthetic strategy to access novel indolactam alkaloids, which are agonists of protein kinase C. This protocol allowed for the most efficient reported syntheses of indolactam V (ILV) stereoisomers, while also affording the large-scale production of natural product (–)-ILV. Structure–activity studies were conducted with these compounds to elucidate the elements necessary to promote PKC-mediated cellular response. EC50measurements in leukemia and lymphoma cell lines, as well as molecular docking analyses with the PKCδ C1B domain, provided the foundation for these studies. A distinct correlation betweenin vitroactivity and the conformation of the macrocyclic lactam ring was discovered, which can guide design efforts for therapeutics that target the PKC regulatory domain.
