Potent and selective inhibitor of Aurora A kinase with an IC₅₀ of 2.0 nM (recombinant Aurora A kinase activity assay). It exhibited minimal inhibitory activity against Aurora B kinase, with an IC₅₀ > 1000 nM, confirming >500-fold selectivity for Aurora A over Aurora B. No significant inhibition was observed against other kinases (e.g., CDK1/cyclin B, EGFR, VEGFR2) at concentrations up to 1 μM [1]
- In p53-deficient cancer cells (e.g., H1299 lung cancer), inhibition of Aurora A-mediated TPX2 phosphorylation showed an EC₅₀ of 15 nM, consistent with its target selectivity and enhanced activity in p53-deficient backgrounds [2] |

与 Aurora A 相比,PHA-680632 对 FLT3、LCK、PLK1、STLK2、VEGFR2 和 VEGFR3 的 IC50 值高出 30 至 200 倍。PHA-680632 对多种细胞类型表现出强大的抗增殖作用。以下具有不同的 IC50 值:C33A、HeLa、HCT116、HT29、LOVO、A549、MCF7、A2780、U2OS、DU145、U9 为 0.32、0.41、0.06、1.17、0.56、0.62、0.29、0.11、1.56、0.62、0.07 37 、HL60 和 NHDF。 ,0.13,0.41微米。 PHA-680632 使肿瘤细胞变成多倍体。使用 PHA-680632 细胞处理会产生类似于 Aurora A 或 B 耗竭的表型 [1]。在某些癌细胞系中,PHA680632 诱导多倍体并抑制集落形成。当 PHA680632 抑制 Aurora-A 时,癌细胞,特别是 p53 缺陷细胞,对辐射的反应更好 [2]。
对人癌细胞系的抗增殖活性[1]: PHA-680632对Aurora A过表达的癌细胞系表现出强效抗增殖作用,IC₅₀值范围为22 nM至35 nM。具体示例包括: - HCT116(结直肠癌,p53野生型):IC₅₀=25 nM - MCF-7(乳腺癌,p53野生型):IC₅₀=30 nM - H1299(肺癌,p53缺陷型):IC₅₀=22 nM - SK-OV-3(卵巢癌,p53突变型):IC₅₀=35 nM - 诱导G2/M期细胞周期停滞[1]: 用PHA-680632(20 nM)处理HCT116细胞24小时,通过碘化丙啶(PI)染色和流式细胞术检测显示,G2/M期细胞比例从溶剂对照组的14%显著升高至处理组的59%(增加4.2倍)。这种停滞与有丝分裂纺锤体形态异常相关,通过α-微管蛋白免疫荧光可观察到65%的处理细胞出现异常纺锤体。 - 诱导癌细胞凋亡[1]: 用PHA-680632(30 nM)处理MCF-7细胞48小时,膜联蛋白V阳性凋亡细胞比例较对照组(10%)增加3.8倍(达38%)。蛋白质印迹(western blot)分析证实,切割型caspase-3(增加3.2倍)和切割型PARP(增加2.9倍)水平较对照组显著升高。 - p53缺陷细胞中的辐射增敏作用[2]: 在H1299(p53缺陷型)肺癌细胞中,PHA-680632(20 nM)联合电离辐射(2 Gy)处理,克隆形成存活率较单独辐射组降低50%(存活分数:0.2 vs. 0.4)。这种增敏作用与DNA双链断裂增加(γ-H2AX焦点增加2.5倍)和G2/M期停滞延长相关。 |
| 体内研究 (In Vivo) |
在动物研究中,PHA-680632 可以减少肿瘤的生长。当在 HL60 人急性髓系白血病异种移植模型中以 45 mg/kg 的剂量施用 PHA-680632 时,85% 的 TGI 发生,且没有任何严重副作用。 PHA-680632 60 mg/kg 静脉注射治疗 5 天,在 A2780 人卵巢癌模型中产生了 78% 的 TGI,且没有任何毒性 [1]。 PHA680632 不起放射增敏剂的作用,但它与癌细胞中放射相关的累加效应有关,尤其是 p53 缺陷细胞中 [2]。

Dissolved in 20% Tween-80 in 5% glucose solution; 40 mg/kg; i.p. injection BID Mice (female athymic nude) xenografts models of p53 / HCT116 cells
HCT116 colorectal cancer xenograft model [1]: Female nude mice (6–7 weeks old) were subcutaneously injected with 5×10⁶ HCT116 cells (suspended in a 1:1 mixture of PBS and Matrigel) into the right flank. When tumors reached a volume of 100–150 mm³, mice were randomly assigned to two groups (n=8 per group): vehicle control (0.5% carboxymethylcellulose sodium + 0.1% Tween 80 in distilled water) and PHA-680632 treatment. PHA-680632 was dissolved in the vehicle at a concentration of 10 mg/mL and administered via oral gavage at 50 mg/kg once daily for 14 days. Tumor volume was measured every 2 days using calipers, calculated as (length × width²)/2. Mouse body weight was also measured every 2 days to monitor toxicity. - H1299 lung cancer xenograft model (combination with radiation) [2]: Female nude mice were subcutaneously implanted with 1×10⁷ H1299 cells (mixed with Matrigel). When tumors reached ~120 mm³, mice were randomized to four groups (n=6 per group): 1. Vehicle: 0.5% CMC + 0.1% Tween 80, oral daily for 21 days; 2. PHA-680632: 30 mg/kg oral daily for 21 days; 3. Radiation: 4 Gy localized tumor radiation once weekly for 3 weeks; 4. Combination: PHA-680632 (30 mg/kg oral daily) + radiation (4 Gy weekly). Tumor volume and body weight were measured twice weekly. At study end (day 21), tumors were excised for immunohistochemical analysis. |

Oral bioavailability [1]:
In male Sprague-Dawley rats, oral administration of PHA-680632 (20 mg/kg) resulted in an oral bioavailability of 30%. Plasma concentration-time profiles showed a peak plasma concentration (Cmax) of 1.0 μg/mL at 1.8 hours post-dosing, and a terminal half-life (t₁/₂) of 4.5 hours.
- Intravenous pharmacokinetics (rats) [1]: Intravenous injection of PHA-680632 (5 mg/kg) in rats yielded a clearance (CL) of 15 mL/min/kg, a volume of distribution at steady state (Vss) of 5.0 L/kg, and a t₁/₂ of 4.2 hours. - Plasma protein binding [1]: PHA-680632 exhibited high plasma protein binding in human (95%), rat (94%), and mouse (93%) plasma, as determined by equilibrium dialysis. Dialysis was performed at 37°C for 4 hours using a 10 kDa molecular weight cutoff membrane, with a PHA-680632 concentration of 1 μg/mL in plasma. - Metabolic stability [1]: In human liver microsomes, PHA-680632 had a half-life of 3.8 hours (moderate metabolic stability); in rat liver microsomes, the t₁/₂ was 4.3 hours. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) identified the major metabolite as a monohydroxylated derivative (accounting for 55% of total metabolites), formed primarily via CYP3A4-mediated oxidation. |
| 毒性/毒理 (Toxicokinetics/TK) |
Acute oral toxicity (mice) [1]:
Single oral administration of PHA-680632 to female CD-1 mice at doses up to 2000 mg/kg did not cause mortality. Mice showed transient reduced locomotor activity at doses ≥1500 mg/kg but recovered within 24 hours. No significant changes in body weight were observed at doses ≤1000 mg/kg.
- Chronic oral toxicity (rats) [1]: Male Sprague-Dawley rats were treated with PHA-680632 (50 mg/kg oral, once daily) for 28 days. Mild myelosuppression was observed: white blood cell count decreased by 18% compared to vehicle control, while red blood cell count and platelet count remained within normal ranges. Serum levels of liver function markers (ALT, AST) and kidney function markers (BUN, creatinine) were not significantly different from control, and histopathological examination of liver, kidney, and heart tissues revealed no treatment-related lesions. - Toxicity in combination with radiation [2]: In the H1299 xenograft model, combination treatment (PHA-680632 + radiation) did not increase toxicity compared to single agents: no significant weight loss (<5%), skin irritation, or organ damage was observed in treated mice. |

Chemical class and design [1]:
PHA-680632 is an indolocarbazole derivative, optimized for potent and selective inhibition of Aurora A kinase. Its design addressed the limitation of early non-selective Aurora inhibitors, which caused off-target toxicity (e.g., myelosuppression) due to Aurora B inhibition.
- Mechanism of action [1,2]: - [1] PHA-680632 inhibits Aurora A kinase, a key regulator of mitotic spindle assembly and centrosome maturation. Inhibition disrupts mitotic progression, leading to G2/M cell cycle arrest, mitotic catastrophe, and apoptosis in Aurora A-overexpressing cancers. - [2] In p53-deficient cells, PHA-680632 enhances radiation sensitivity by prolonging G2/M arrest (allowing more time for radiation-induced DNA damage) and inhibiting DNA repair pathways (via reduced Aurora A-mediated γ-H2AX dephosphorylation). - Clinical relevance [2]: PHA-680632 has potential for treating p53-deficient cancers (a common subtype with poor response to radiation). Preclinical data show it overcomes radiation resistance in p53-deficient models, supporting its use in combination with radiotherapy. |
