| Bioactivity | Rabdosin B is an ent-kaurene diterpenoid with anticancer effects. Rabdosin B induces DNA damage in cells, and inhibits lettuce root hair development of seedlings[1][2]. |
| Invitro | Rabdosin B (200 μM; 3-12 h) 诱导根分生组织细胞 G2 期和 S 期的细胞周期延迟。Rabdosin B 显示 DNA 损伤呈时间和剂量依赖性增加[1]。Rabdosin B 对生菜幼苗 (Lactuca sativa L.) 的根生长显示出双相、剂量依赖性作用和对根毛发育的强烈抑制作用。 较低浓度的 Rabdosin B (20-80 μM) 显着促进根系生长，但相比之下，其 120-200 μM 的较高水平具有抑制作用。此外，所有测试浓度 (10-40 μM) 均以剂量依赖性方式抑制幼苗的根毛发育[1]。Rabdosin B 对人肿瘤 HepG2、GLC-82 和 HL-60 细胞系具有细胞毒性，IC50 值分别为 8.95 μM、4.47 μM 和 10.22 μM[2]。Rabdosin B (6 μM、9 μM、12 μM、15 μM；24-48 小时) 以时间和剂量依赖性方式对 HepG2 细胞造成显着的 DNA 损伤[2]。 Cell Cycle Analysissup>[1] Cell Line: |
