实验例 7、 2-吲哚酮衍生物 (Indo 5)抑制肝癌细胞中 c- Met磷酸化及信号通 路实验
已有文献表明, HGF介导的 c-Met信号通路化合物在肿瘤发生发展中发挥重要作 用。 c-Met激酶是肝细胞生长因子 HGF的高亲和力受体, 在组织损伤修复、 伤口愈 合、 肝再生及胚胎发育过程中行使重要功能。 研究表明 c-Met的异常表达可直接导 致肿瘤发生。 c-Met通过与 HGF结合后, 激活下游信号通路, 破坏肿瘤细胞间的黏 附,促进细胞运动,进而增强肿瘤细胞的侵袭能力及血管生成。临床肿瘤病人中 c-Met 的异常表达与肿瘤病人的预后差、 疾病进程快、 高转移及生存期短密切相关。 c-Met 已成为国际上公认的肿瘤治疗靶标。 本发明采用了两种肝癌细胞系检测了化合物对 c-Met信号通路的影响。 HepG2细胞高表达 c-Met,可在 HGF刺激下发生 e-Met磷酸 化及其下游信号通路包括 ERK、 Akt等的活化。 MHCC97-H细胞是自分泌 HGF的肝 癌细胞系, 因此, 在正常培养条件下该细胞具有较高的持续的 c-Met磷酸化水平。
用两种肝癌细胞系 HepG2和 MHCC97-H检测本发明 2-吲哚酮衍生物 (以 Indo 5 为例) 对 HGF诱导的 c-Met磷酸化及信号通路的抑制效果。
细胞培养: 高表达 c-Met的肝癌细胞系 HepG2或 c- Met持续活化的肝癌细胞系 MHCC97- H培养于含 10%胎牛血清的 1640细胞培养液中 (补充青霉素、 链霉素各 ΙΟΟμΙ/mL) , 置于 37°C含 5% C02的细胞培养箱中, 每 1-2天换液一次。 0. 25%胰 酶消化传代, lOOOr/min离心 5分钟后, 弃上清液, 加入新鲜培养基传代培养。
Western blot检测:
(A)针对 HepG2细胞:无血清培养 24小时的 HePG2细胞加入不同浓度(0. ΙμΜ, 0. 5μ , Ι. ΟμΜ, 2. ΟμΜ) 的 Indo 5或溶剂 DMS0 (0) 预孵育 2h, 而后加入 20ng/mL 的 HGF (不加的记为 "-")刺激 5min, 细胞裂解后提取总蛋白。用 c- Met磷酸化和非 磷酸化抗体、 ERK磷酸化和非磷酸化抗体, Akt磷酸化和非磷酸化抗体(均购自 Cell Signaling公司) 和 GAPDH抗体 (购自 Santa Cruz公司) 进行 Western blot检测。
(B) 针对 MHCC97- H细胞: 向正常培养 24小时的 MHCC97-H细胞加入不同浓度 (0. ΙμΜ, 0. 5μΜ, 1. ΟμΜ, 2. ΟμΜ) 的 Indo 5或溶剂 DMS0 (0) 或 ΙμΜ SU11274处理 细胞。 SU11274 (购自 Sigma公司) 是特异的 c- Met激酶抑制剂, 可阻断 c- Met活 化, 但该化合物由于溶解度及副作用大等原因, 并不是一个合适的临床用药物, 但 实验中可用做阳性对照化合物。 化合物与细胞孵育 2h后, 收取细胞提取总蛋白。 用 c-Met磷酸化和非磷酸化抗体、 ERK磷酸化和非磷酸化抗体、 Akt磷酸化和非磷酸化 抗体 (均购自 Cell Signaling公司) 和 GAPDH抗体 (购自 Santa Cruz公司) 进行 Western blot检测。 实验结果如图 6A和图 6B所示, 在 HepG2细胞中 HGF迅速诱导 c- Met磷酸化, Indo 5能够以剂量依赖方式抑制 HGF诱导的 c- Met磷酸化, 在 2μΜ时几乎完全抑制 Met磷酸化, 并抑制了 c-Met下游关键信号分子 Akt和 ERK的磷酸化(参见图 6A) 。
MHCC97-H细胞是一种具有高转移特性的人肝癌细胞, 该细胞可分泌 HGF, 并通过自 分泌的形式激活 HGF/c- Met信号通路。 MHCC97-H细胞在正常培养条件下细胞具有较 高水平的 c-Met磷酸化, 加入 Indo 5能够以剂量依赖方式抑制 c-Met磷酸化及其下 游信号通路分子 Akt和 ERK的磷酸化 (参见图 6B) ; 该结果与阳性对照 SU11274比 较, 在 2μ 浓度下, Indo 5的抑制效果与 SU11274效果相当。 上述结果表明本发明 的 2 吲哚酮衍生物 (Indo 5 ) 以剂量依赖方式显著抑制 c- Met活化及其下游信号分 子 ERK的磷酸化, 提示其在体外细胞中可有效抑制 HGF/c- Met, 有开发为抗肝癌及 c-Met异常活化肿瘤治疗药物的可能。
实验例 8、 Indo 5抑制细胞内 TrkA及 TrkB磷酸化及信号通路实验
Trk (NTRK)激酶属于受体酪氨酸激酶家族中的一个小家族, 该家族激酶是神经 营养蛋白 (neurottophin) 受体, 在中枢及周围神经系统的发育与维持中作用重要。 成员包括 TrkA (NTRK1), TrkB (NTRK2)和 TrkC (NTRK3)。 Trk与肿瘤发生发展密切 相关, 对 Trk信号通路的抑制已经成为肿瘤治疗的策略之一。 针对 Trk的小分子抑 制剂及基于治疗用的单克隆抗体已经被用于外周疼痛的临床干预、 中枢神经系统异 常及肿瘤的治疗中。 TrkA是 NGF的高亲和性受体, TrkB是 BDNF的高亲和力受体, 检测 TrkA磷酸化、 TrkB磷酸化及下游信号就可评价本发明 2-吲哚酮衍生物(以 Indo5 为例) 对该细胞通路的影响, 进而可以推知与该细胞通路相关的神经母细胞瘤、 乳 腺癌、 肺癌等的抑制作用。
实验方法:神经母细胞瘤细胞 SK- N- SH培养于含 10%胎牛血清的 1640细胞培养 液中 (补充青霉素、 链霉素各 ΙΟΟμΙ/mL) , 置于 37°C含 5% C02的细胞培养箱中, 每 1-2天换液一次。 用 0. 25%胰酶消化传代, 1000r/min离心 5分钟后, 弃上清液, 加入新鲜培养基传代培养。 无血清培养 24小时的 SK- N-SH细胞加入不同浓度
(0. 05μΜ, 0. ΙμΜ, 0. 5μΜ, 1. ΟμΜ) 的 Indo 5, 或溶剂 DMS0 ( 0) 预孵育 2h, 而后加 入 500ng/mL的 NGF或 200ng/mlBDNF (不加的记为 "-")刺激 5min, 细胞裂解后提取 总蛋白,用 TrkA磷酸化和非磷酸化(p- TrkA)抗体、 TrkB磷酸化和非磷酸化(p-TrkB) 抗体、 ERK磷酸化和非磷酸化 (P- ERK) 抗体、 Akt磷酸化和非磷酸化抗体 (p- Akt ) 及 GAPDH抗体进行 Western blot检测。
实验结果如图 7所示, 本发明 2-吲哚酮衍生物 (Indo 5) 以剂量依赖方式显著 抑制 TrkA及其下游信号分子 ERK的磷酸化; 如图 8所示, 本发明 2-吲哚酮衍生物
( Indo 5) 以剂量依赖方式显著抑制 TrkB及其下游信号分子包括 ERK及 Akt的磷酸 化, 提示本发明 2-吲哚酮衍生物(Indo 5 )在体外细胞中可有效抑制 Trk信号通路, 有开发为抗神经母细胞瘤、 乳腺癌、 肺癌等治疗药物的可能。
实验例 9、 Indo 5体内抑制神经母细胞瘤 SK- N- SH细胞生长实验

实验方法: 腹腔注射, 注射剂量分别为 ½g/kg、 8mg/kg、 16mg/kg的腹腔给药 组及灌胃给药组 (16mg/kg) , 溶剂对照组注射相同体积的 DMSO (control ) , 每组 10只实验动物; 24h给药一次, 共给药 6次, 在给药过程中实时监测并记录肿瘤体 积(长 X宽 X宽 /2) 的变化情况, 结果用均数土标准差表示。 2周后处死小鼠, 剥离 肉眼可见肿瘤称重, 并最终计算化合物对肿瘤的抑制率。
