Synthesis of 2,4,6-Tripyridyl Pyridines, and Evaluation of Their Antitumor Cytotoxicity, Topoisomerase I and II Inhibitory Activity, and Structure-activity Relationship
摘要:
合成了一系列 2,4,6-三吡啶基吡啶,并对其抗肿瘤细胞毒性、拓扑异构酶 I 和 II 抑制活性进行了评估。与 2,2':6',2"-三吡啶和多柔比星相比,18 个制备的化合物中,化合物 10-12 对几种人类癌细胞株具有更好或相似的细胞毒性。其中,化合物 10 的细胞毒性最强,优于阳性对照。结构-活性关系研究表明,2,2':6',2"-三联吡啶骨架在对几种人类癌细胞系产生显著的细胞毒性方面起着重要作用。

The enantioselective synthesis of chiral azaarenes by rhodium‐catalyzed asymmetric conjugate addition of organoboronic acids to carbonyl‐activated alkenyl azaarenes was reported. Diverse chiral azaarenes were produced in up to 99% yield and with up to 99% ee (>60 examples). Catalytic asymmetric syntheses of dexchlorpheniramine and dexbrompheniramine were realized by using the developed method.
