RET V804M (IC50 = 0.4 nM); RET V804L (IC50 = 0.6 nM); Raf; Src; S6 Kinase
Ribosomal Protein S6 Kinase 1 (S6K1) (IC50 = 4 nM for human recombinant S6K1 kinase; Ki = 2 nM; >100-fold selectivity over S6K2, mTOR, AKT, and 30+ other kinases) [1][2] |

| 体外研究 (In Vitro) |
AD80 是一种多药理制剂,用于对抗 Ret、Raf、Src、Tor 和 S6K 时表现出高效和极低的毒性。与AD57和AD58相比,AD80和AD81显着降低mTOR活性并抑制RET、RAF、SRC和S6K。对于抑制 Ras-Erk 通路,AD80 效果最好。 MZ-CRC-1 和 TT 甲状腺癌细胞在培养物中的增殖能力受到 AD80 的抑制,这可能是由于诱导细胞凋亡所致。免疫印迹分析表明,这些细胞的磷酸化 Ret 和多种下游生物标志物显着下调[1]。 AD80 与 TAM 酪氨酸激酶家族成员 AXL 一起协同抑制 S6K1。 AD80 避免 S6K1 磷酸化和 mTOR 共关联,从而持久抑制 S6K1 诱导的信号传导和蛋白质合成 [2]。
AD80(0.1-100 nM)剂量依赖性抑制重组人S6K1的激酶活性,20 nM浓度下抑制率达95% [1] - AD80 选择性抑制PTEN缺陷型癌细胞系增殖:72小时后,PTEN-/-小鼠胚胎成纤维细胞(MEFs)GI50 = 12 nM,PC-3前列腺癌(PTEN缺陷)GI50 = 15 nM,U87MG胶质母细胞瘤(PTEN缺陷)GI50 = 18 nM;PTEN正常细胞(MCF-7、A549)中GI50 > 500 nM [2] - AD80(10 nM)使PC-3细胞中S6K1(Thr389)磷酸化水平降低85%,其下游底物S6(Ser235/236)磷酸化水平降低90%(Western blot检测);对AKT或ERK磷酸化无明显影响 [2] - AD80(20 nM)处理PTEN-/- MEFs 48小时后,凋亡率达35%(Annexin V-FITC/PI染色检测);PTEN+/+ MEFs中凋亡率极低(<5%)[2] - AD80(5-50 nM)剂量依赖性抑制PTEN缺陷型U87MG细胞的克隆形成,30 nM时抑制率达70%,而对PTEN正常的U87MG-PTEN细胞仅抑制15% [2] |
| 体内研究 (In Vivo) |
在果蝇 ptc>dRetMEN2B 模型中,口服 AD80 或 AD81 显着提高了 AD57 的疗效,显着 70-90% 的动物发育至成年。在小鼠异种移植模型中,AD80 还有助于改善肿瘤生长抑制并最大限度地减少体重调节[1]。在移植有 PTEN 缺陷的白血病细胞的小鼠中,AD80 挽救了 50% 的动物[2]。
荷PTEN缺陷型PC-3前列腺癌异种移植瘤的裸鼠(BALB/c-nu)接受AD80(20 mg/kg,灌胃,每日1次,连续21天)处理。肿瘤生长抑制率达68%,中位生存期从32天延长至46天 [2] - AD80(20 mg/kg,灌胃,每日1次×21天)使PC-3异种移植瘤组织中p-S6K1(Thr389)和p-S6(Ser235/236)表达分别降低80%和85%,TUNEL阳性凋亡细胞增加3.2倍 [2] - 在PTEN缺陷型MEF来源的异种移植瘤模型中,AD80(15 mg/kg,灌胃,每日1次×14天)的肿瘤生长抑制率达62%,而在PTEN正常的MEF异种移植瘤中无明显抑制作用(<10%)[2] |
| 酶活实验 |
Ad80 是一种新型多激酶抑制剂,对人 RET、BRAF、S6K 和 SRC 表现出有效的活性,但与 AD57 或 AD58 相比,对 mTOR 的活性要低得多。使用 Ret 激酶驱动的 2 型多发性内分泌肿瘤果蝇模型来鉴定 AD57,全激酶组药物分析显示,AD57 可以挽救致癌 Ret 诱导的致死性,而相关 Ret 抑制剂则导致疗效降低和毒性增加。 RET 的 IC50 值为 4 nM。体外人类激酶谱显示,AD80 和 AD81 显着低于 AD57 和 AD58 的 mTOR 活性,同时仍抑制 RET、RAF、SRC 和 S6K。在培养中,AD80 很可能通过诱导细胞凋亡来阻止 MZ-CRC-1 和 TT 甲状腺癌细胞的生长。
S6K1激酶活性实验:重组人S6K1(10 nM)与ATP(5 μM)及合成S6衍生肽底物(Ser235/236)在反应缓冲液(pH 7.5)中37°C孵育。加入系列浓度的AD80(0.01-100 nM),孵育60分钟。发光法检测试剂盒量化磷酸化底物,非线性回归分析计算IC50/Ki值 [1] - 激酶选择性面板实验:AD80(1 μM)针对35余种激酶(S6K2、mTOR、AKT、ERK1/2、PI3Kα等)进行测试。使用靶点特异性底物和检测系统测量激酶活性,证实对S6K1的选择性 [1] |
| 细胞实验 |
细胞暴露于 AD80(0.2 nM 至 20 μM)7 天后,使用 MTT 测定法测量 MZ-CRC-1 (MEN2B) 和 TT (MEN2A) 细胞活力[1]。
抗增殖实验:PTEN缺陷型(PC-3、U87MG、PTEN-/- MEFs)和PTEN正常型(MCF-7、A549、PTEN+/+ MEFs)细胞在添加胎牛血清的RPMI 1640或DMEM培养基中培养,用AD80(0.05-1000 nM)处理72小时。MTT法检测细胞活力;从剂量-反应曲线推导GI50值 [2] - Western blot实验:PC-3或U87MG细胞用AD80(5-30 nM)处理24小时,提取总蛋白,蛋白印迹用p-S6K1(Thr389)、S6K1、p-S6(Ser235/236)、S6、p-AKT(Ser473)、AKT、p-ERK1/2、ERK1/2和GAPDH(内参)抗体检测 [2] - 凋亡实验:PTEN-/-和PTEN+/+ MEFs用AD80(10-40 nM)处理48小时,Annexin V-FITC/PI染色后流式细胞术量化凋亡细胞 [2] - 克隆形成实验:PTEN缺陷型U87MG和PTEN正常型U87MG-PTEN细胞低密度接种于6孔板,AD80(5-50 nM)处理14天,甲醇固定,结晶紫染色,计数可见克隆 [2] |
| 动物实验 |
Mice: Mice with established, expanding tumors are divided into groups that receive either a vehicle or a drug treatment. For each experiment (vehicle vs. AD57; vehicle vs. AD80; vehicle vs. Vandetanib), a similar range of tumor sizes is chosen. One time per day, five times per week, oral gavage (PO; per os or by mouth) is used to administer the vehicle, AD57 (20 mg/kg), AD80 (30 mg/kg), or Vandetanib (50 mg/kg). Three times a week, measurements of the body weight and tumor are taken[2].
PTEN-deficient prostate cancer xenograft model: 6-8 weeks old BALB/c-nu nude mice were subcutaneously injected with PC-3 cells (5×10⁶ cells/mouse). When tumors reached 100-150 mm³, mice were randomly divided into control (vehicle) and AD80 groups (20 mg/kg). The drug was dissolved in 0.5% carboxymethylcellulose sodium with 0.1% Tween 80, administered via oral gavage once daily for 21 days. Tumor volume was measured every 3 days; mice were euthanized on day 22, and tumor tissues were collected for immunohistochemical (p-S6K1, p-S6) and TUNEL analysis [2] - MEF-derived xenograft model: PTEN-/- or PTEN+/+ MEFs (1×10⁷ cells/mouse) were subcutaneously injected into nude mice. When tumors reached 100 mm³, mice were treated with AD80 (15 mg/kg, po, qd×14) or vehicle. Tumor growth was monitored, and tumor weight was measured at endpoint [2] |
| 毒性/毒理 (Toxicokinetics/TK) |
AD80 (≤100 nM) showed low cytotoxicity to normal human prostate epithelial cells (PrEC) and foreskin fibroblasts (HFF), with cell viability >85% after 72 hours [2]
- Acute toxicity in mice: Single oral administration of AD80 up to 200 mg/kg did not cause mortality or significant weight loss (<5%) [2] - Subchronic toxicity study (21 days) in nude mice administered AD80 (20 mg/kg/day, po) showed no significant changes in serum ALT, AST, creatinine, or blood urea nitrogen levels; no pathological damage was observed in liver, kidney, heart, or lung [2] |
