JNJ-7706621 对一系列人类肿瘤细胞(包括 HeLa、HCT116 和 A375)具有抗增殖活性,IC50 值分别为 284、254 和 447 nM [1]。在早期有丝分裂期间,JNJ-7706621 抑制 TOG、Nek2 和 TACC3 等中心体蛋白,但它不会阻止 Aurora A 定位到纺锤体极。通过抑制纺锤体检查点信号传导,JNJ-7706621 治疗诺考达唑同步细胞可以防止有丝分裂停滞并防止染色体排列和分离失败 [2]。当针对最高浓度的 Plk1 或 Wee1 丝氨酸/苏氨酸激酶进行测试时,JNJ-7706621 没有活性,但抑制 Aurora-A 和 Aurora-B。 JNJ-7706621 的 IC50 值范围为 112 至 514 nM,在体外对所有人类癌细胞类型表现出强烈的生长抑制作用 [3]。 JNJ-7706621 悬浮液抑制 HeLa 细胞活力,24 小时和 48 小时的 IC50 值分别为 2.1 和 0.9 μg/mL。负载 JNJ-7706621 的纳米颗粒的 IC50 分别为 35 和 2.7 μg/mL,而胶束的 IC50 分别为 6.3 和 1.6 μg/mL [4]。

Dissolved in 0.5% methylcellulose containing 0.1% polysorbate 80 in sterile water; 100, 125 mg/kg; oral administration or i.p. injection. Mouse xenograft model of A375 cells
HCT116 colon cancer xenograft model: Female nude mice (6-8 weeks old) were subcutaneously injected with 5×10⁶ HCT116 cells into the right flank. When tumors reached 100-150 mm³, mice were randomly divided into two groups (n=6/group): vehicle group (0.5% methylcellulose + 0.2% Tween 80) and JNJ-7706621 group. JNJ-7706621 was dissolved in the vehicle and administered i.p. at 25 mg/kg once daily for 14 days. Tumor volume (calculated as length × width² / 2) and mouse body weight were measured every 2 days [3] - MCF-7 breast cancer xenograft model: Female nude mice were implanted with 1×10⁷ MCF-7 cells (mixed with Matrigel) subcutaneously. When tumors reached 100 mm³, mice were grouped (n=6/group). JNJ-7706621 was suspended in 0.5% carboxymethylcellulose and administered orally at 50 mg/kg twice daily for 21 days. Tumor weight was measured at the end of the experiment, and TGI was calculated as [1 - (tumor weight in treated group / tumor weight in control group)] × 100% [2] |

Oral bioavailability: In rats, oral administration of JNJ-7706621 (20 mg/kg) resulted in an oral bioavailability of 15%. Plasma concentration-time profile showed a Cmax of 0.8 μg/mL at 1 h post-dosing and a half-life (t₁/₂) of 3.5 h [4]

The major metabolite was identified as a monohydroxylated derivative [4] |
| 毒性/毒理 (Toxicokinetics/TK) |
Acute toxicity in mice: Single i.p. administration of JNJ-7706621 up to 100 mg/kg did not cause mortality, but mice showed transient reduced activity at doses ≥75 mg/kg. No significant changes in liver or kidney function markers (ALT, AST, BUN, creatinine) were observed at 72 h post-dosing [3]
- Chronic toxicity in rats: Daily oral administration of JNJ-7706621 (20 mg/kg) for 28 days resulted in mild myelosuppression (decreased white blood cell count by 20%), but no other organ toxicity (liver, kidney, heart) was detected via histopathological examination [4] |

4-[[5-amino-1-[(2,6-difluorophenyl)-oxomethyl]-1,2,4-triazol-3-yl]amino]benzenesulfonamide is a sulfonamide.
JNJ-7706621 is a poorly soluble small molecule (solubility <1 μg/mL in water), which limits its oral bioavailability. To improve solubility, lipid-based formulations were developed, which increased oral bioavailability to 30% in rats [4] - The mechanism of action of JNJ-7706621 involves dual inhibition of CDKs (which regulate cell cycle progression) and Aurora kinases (which control mitotic spindle assembly), leading to cell cycle arrest at G2/M phase and subsequent apoptosis in cancer cells [2,3] - N-acyl sulfonamide prodrugs of JNJ-7706621 were synthesized to improve solubility and bioavailability. The prodrugs showed increased aqueous solubility (10 μg/mL) and were converted to the parent drug JNJ-7706621 in human plasma with a half-life of 1 h [1] |
