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IC50=(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.

Abstract

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 (IC50=(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.

Key words： ent-kaurene diterpene; Jiyuan oridonin A (JOA); anti-proliferative activity; reactive oxygen species (ROS) pathway
