摘 要:济源冬凌草甲素(JOA)是从河南省济源市收集的冬凌草中纯化得到的二萜类成分,表现出多种抗肿瘤活性.为了进一步研究JOA的药用效果,设计合成了一系列其14-OH苯甲酸衍生物,随后评估了它们的体外抗增殖活性.结果证明,该系列衍生物的抗肿瘤活性优于先导化合物JOA及冬凌草甲素.其中,7α,20-内酯-对映-贝壳杉-16-烯-11,15二酮-14β-(2-硝基-5-氯苯甲酸)酯(OJW8-9)的活性最好[对SW1990细胞的IC_(50)=(0.478±0.109)μmol/L].进一步的作用机制研究表明,化合物OJW8-9通过阻断处于G2/M期的SW-1990来抑制细胞增殖,且具有浓度依赖性,其可能通过活性氧(ROS)途径诱导细胞凋亡.Jiyuan oridonin A(JOA),a diterpenoid ingredient purified from Isodon rubescens collected in Jiyuan,Henan Province,exhibited a variety of anti-tumor activities.In order to further develop the medicinal potency of JOA,a series of its 14-OH benzoate derivatives were designed and synthesized,and then their anti-proliferative activities in vitro were evaluated.The results turned out that the anti-tumor activities of this series of derivatives had been improved compared with the those of JOA,and were much better than that of oridonin.Among them,7α,20-olide-ent-kaur-16-en-11,15-dione-14β-yl 2-nitro-5-chlorobenzoate(OJW8-9)showed the best activity(IC_(50)=(0.478±0.109)μmol/L on SW-1990 cells).Further studies revealed that compound OJW8-9 inhibited the proliferation of SW-1990 cells by blocking cell cycle in the G2/M phase in a time-and concentration-dependent,and might induce apoptosis through reactive oxygen species(ROS)pathway.
