Graphene oxide was found to be a highly efficient and cost-effective heterogeneous catalyst for the direct metal-free transformation of quinoline and isoquinoline N-oxides into the corresponding nitriles under mild conditions. This method is simple, economic and environmentally benign, representing a useful strategy for the convenient synthesis of α-cyano N-oxides that are difficult to prepare by
发现氧化石墨烯是在温和条件下将喹啉和异喹啉N-氧化物直接无金属转化为相应腈的一种高效且具有成本效益的非均相催化剂。该方法简单,经济且对环境无害,代表了一种有用的策略,可方便地合成无过渡金属催化方法难以制备的α-氰基N-氧化物。在体外,化合物2s对T-24细胞系表现出良好的活性,IC 50值为10.23±1.05μM。进一步的研究探讨了有效抑制细胞生长的机制,包括凋亡率检测,细胞周期分析,钙离子测量2+代,ROS和线粒体功能障碍。
