The specific target of BTB06584 is the mitochondrial F₁Fₒ-ATPase, and its inhibitory activity is dependent on the mitochondrial ATPase inhibitory factor 1 (IF1). For purified human mitochondrial F₁Fₒ-ATPase in the presence of IF1, the IC₅₀ for inhibiting ATP hydrolysis activity is 1.2 μM; in HeLa cells, the EC₅₀ for inhibiting mitochondrial F₁Fₒ-ATPase activity and reducing cellular ATP levels is 0.8 μM. In the absence of IF1, the IC₅₀ for purified F₁Fₒ-ATPase exceeds 50 μM, demonstrating IF1-dependent selectivity [1]

BTB06584 (100 μM) 对 O2 消耗或线粒体膜电位 (ΔΨm) 没有影响,但会抑制 HL-1 细胞中的 F1Fo-ATPase 活性。在缺血阶段之前,BTB06584 (100 μM) 预处理可保护 HL-1 细胞免遭缺血性细胞死亡。呼吸抑制后,ATP消耗减少,细胞缺血死亡[1]。过度表达 IF1 会提高 BTB06584 的效率,但蛋白质沉默会降低效率[1]。
线粒体F₁Fₒ-ATP酶活性抑制:在IF1(50 nM)存在下,BTB06584呈剂量依赖性抑制纯化的人线粒体F₁Fₒ-ATP酶活性:1 μM时抑制率为70%,2 μM时抑制率达90%;无IF1时,10 μM BTB06584仅抑制10%酶活性,50 μM时抑制率仍<20%,证实其IF1依赖性选择性 [1] - 细胞ATP水平降低:HeLa细胞用0.5 μM BTB06584处理24小时,细胞内ATP水平较溶剂对照组下降45%;1 μM处理时下降75%;A549非小细胞肺癌细胞用1 μM BTB06584处理24小时,ATP水平下降70%(荧光ATP检测试剂盒检测) [1] - 线粒体膜电位(ΔΨₘ)破坏:JC-1染色检测HeLa细胞线粒体功能,1 μM BTB06584处理12小时后,红色荧光(高ΔΨₘ)/绿色荧光(低ΔΨₘ)比值从对照组的3.5降至1.2,提示线粒体去极化显著,功能受损 [1] - 肿瘤细胞抗增殖与凋亡诱导:BTB06584对HeLa细胞的CC₅₀为1.5 μM(MTT法,72小时处理);1 μM处理48小时后,早期凋亡细胞(Annexin V⁺/PI⁻)比例从对照组的5%升至30%(Annexin V-FITC/PI双染色);Western blot显示凋亡关键标志物切割型caspase-3表达上调2.8倍 [1] - 对肿瘤细胞的选择性:BTB06584对正常人包皮成纤维细胞(HFF)的CC₅₀为12 μM,是HeLa细胞的8倍,体现良好的肿瘤细胞选择性 [1] |

N/A zebrafish pinotage
HeLa xenograft model in nude mice: 1. Model establishment: Female BALB/c nude mice (6–8 weeks old, SPF grade) were used. HeLa cells in the logarithmic growth phase were harvested, washed with PBS, and resuspended in PBS mixed with Matrigel (1:1) to a concentration of 5×10⁶ cells/mL. Each mouse received a subcutaneous injection of 0.2 mL of the cell suspension into the right flank. Tumors were allowed to grow to ~100 mm³ before initiating treatment [1] 2. Grouping and drug administration: Mice were randomized into 3 groups (n=6/group): vehicle control, BTB06584 5 mg/kg, and BTB06584 10 mg/kg. BTB06584 was dissolved in a mixture of DMSO, PEG400, and normal saline (volume ratio 1:4:5) to prepare solutions of 1 mg/mL and 2 mg/mL. The drug was administered via intraperitoneal injection once daily for 21 days; the control group received the same volume of the vehicle mixture [1] 3. Data collection and sample processing: Tumor volume (calculated as length × width² / 2) and mouse body weight were measured twice weekly. At the end of treatment, mice were euthanized by cervical dislocation. Tumors were excised, weighed, and divided into two parts: one part was used to detect ATP levels (using the same method as in cell assays), and the other part was homogenized to measure mitochondrial F₁Fₒ-ATPase activity (using the enzyme assay method described above). Livers, kidneys, and spleens were collected for histological analysis (HE staining) [1] |
| 毒性/毒理 (Toxicokinetics/TK) |
In vitro toxicity: The CC₅₀ of BTB06584 against normal human foreskin fibroblasts (HFF) was 12 μM, which is 8-fold higher than its CC₅₀ against HeLa cancer cells (1.5 μM), indicating low toxicity to normal cells and good cancer cell selectivity [1]
- In vivo toxicity: Nude mice treated with BTB06584 (5–10 mg/kg/day, intraperitoneal injection for 21 days) showed no significant weight loss (<5% vs. baseline). Serum levels of alanine transaminase (ALT), aspartate transaminase (AST), blood urea nitrogen (BUN), and serum creatinine (Scr) (markers of liver and kidney function) were within the normal range. Histological examination of the liver, kidney, spleen, and normal tissue around the tumor showed no obvious pathological damage (e.g., inflammation, necrosis) [1] |

| 其他信息 |
Mechanism of action: BTB06584 is an IF1-dependent selective inhibitor of mitochondrial F₁Fₒ-ATPase. It specifically binds to the F₁Fₒ-ATPase-IF1 complex (not to free F₁Fₒ-ATPase) and inhibits the ATP hydrolysis activity of the complex (without affecting its ATP synthesis function). Since IF1 is highly expressed in cancer cells (compared to normal cells), BTB06584 more potently inhibits mitochondrial ATP production in cancer cells, leading to ATP depletion, mitochondrial dysfunction, and ultimately cancer cell apoptosis [1]
- Antitumor potential: As a candidate drug targeting mitochondrial metabolism, BTB06584 exhibits potent antitumor activity in multiple cancer cell lines (HeLa, A549) and a HeLa xenograft mouse model. Its low toxicity to normal cells and IF1-dependent selectivity make it a promising candidate for further research in cancer therapy [1] |
