FT113 对 PC3 和 MV-411 细胞表现出抗增殖活性,IC50 值分别为 47 和 26 nM [1]。
FT113 在使用全长重组人FASN酶的生化分析中表现出强效的抑制活性,IC₅₀为213 nM。 [1] 在细胞实验中,FT113 在脂质减少血清培养基中培养的PC3人前列腺癌细胞中显示出抗增殖活性,IC₅₀为47 nM。 [1] 在BT474人乳腺癌细胞中,通过¹⁴C-乙酸掺入实验测量,FT113 抑制FASN活性,IC₅₀为90 nM。 [1] FT113 对MV-411人急性髓系白血病细胞也显示出抗增殖活性,IC₅₀为26 nM。 [1] 该化合物表现出优异的微粒体稳定性,在小鼠肝微粒体中孵育30分钟后剩余100%。 [1] FT113 在pH 7.4下的动力学溶解度为39 µM。 [1] 计算LogP (clogP)为1.3,亲脂性效率 (LipE) 为5.4。 [1] |
| 体内研究 (In Vivo) |
在小鼠和模拟器中,FT113(5 mg/kg,小鼠)的口服生物利用度分别为 95% 和 84% [1]。在小鼠中,FT113(5、25 或 50 mg/kg,口服,每天两次,持续 16 天)可增加肿瘤中丙二酰辅酶 A 的浓度,并剂量耦合肿瘤生长抑制作用 [1]。
在MV-411人癌细胞系小鼠异种移植模型中,口服给予FT113 (5、25和50 mg/kg,每日两次,持续16天) 导致肿瘤内丙二酰辅酶A (FASN的底物) 水平呈剂量依赖性增加,表明在肿瘤组织内实现了靶点结合和FASN活性抑制。 [1] 与载体对照组相比,使用FT113 (25和50 mg/kg,每日两次) 治疗16天,分别实现了32%和50%的肿瘤生长抑制。 [1] |
| 酶活实验 |
使用CPM (7-二乙氨基-3-(4'-马来酰亚胺基-苯基)-4-甲基香豆素) 分析法,使用全长重组人FASN酶测定化合物对FASN的生化效力。该分析法通过检测荧光CPM-CoA络合物的形成来测量辅酶A (CoA) 的产量。 [1]

| 细胞实验 |
在PC3人前列腺癌细胞中评估抗增殖活性。细胞在补充了10%脂质减少血清 (LRS) 的生长培养基中培养,在此条件下PC3细胞的生长依赖于 de novo 脂肪生成 (DNL)。在FASN抑制剂存在下测量细胞活力/增殖。 [1]
在BT474人乳腺癌细胞中使用¹⁴C-乙酸掺入分析法测量细胞环境中的FASN酶活性。该分析法测量¹⁴C-乙酸转化为¹⁴C-乙酰辅酶A及其随后被细胞FASN掺入新合成的放射性标记棕榈酸中的过程。对此过程的抑制反映了细胞FASN抑制。 [1] 也在MV-411人急性髓系白血病细胞中评估了抗增殖活性。 [1] |
| 动物实验 |
Animal/Disease Models: Athymic nude mice bearing MV-411 cells [1]
Doses: 5, 25, or 50 mg/kg Route of Administration: Orally, twice (two times) daily for 16 days Experimental Results: In mice, 25 mg/kg and 50 mg/kg inhibited tumor growth by 32% and 50%, respectively. Pharmacokinetic Study: FT113 was administered orally to female Balb/c nude mice at a dose of 5 mg/kg. The dosing formulation was a 9:1 (v/v) mixture of PEG400 and ethanol. Blood samples were collected at various time points to determine plasma concentration-time profiles. [1] Pharmacokinetic Study: FT113 was administered orally to male Sprague-Dawley rats at a dose of 5 mg/kg. The dosing formulation was a 9:1 (v/v) mixture of PEG400 and ethanol. Blood samples were collected to determine plasma concentration-time profiles. [1] Efficacy Study (Xenograft Model): Athymic nude mice bearing subcutaneous MV-411 human cancer cell line xenografts were used. When tumor volumes reached 130–140 mm³, mice were randomized into groups (n=4 per group). Mice received vehicle (9:1 PEG400/ethanol) or FT113 at 5, 25, or 50 mg/kg, administered orally twice daily (b.i.d.) for 16 days. Tumors were harvested 4 hours after the last dose for biomarker (malonyl-CoA) analysis. Tumor volumes were also monitored to assess growth inhibition. [1] |
| 药代性质 (ADME/PK) |
In female Balb/c nude mice following a single 5 mg/kg oral dose, FT113 achieved a maximum plasma concentration (Cmax) of 8.4 µM at 2 hours (tmax). The area under the plasma concentration-time curve from 0 to 8 hours (AUC₀₋₈h) was 46 µM·h. The oral bioavailability was 95%. [1]
In male Sprague-Dawley rats following a single 5 mg/kg oral dose, FT113 achieved a Cmax of 33 µM at 3 hours (tmax). The AUC₀₋₈h was 440 µM·h. The oral bioavailability was 84%. [1] |
| 毒性/毒理 (Toxicokinetics/TK) |
FT113 showed no acute toxicity when dosed orally at 5 mg/kg in mice, in contrast to its 5-fluorobenzoxazole analog (compound 27) which was not tolerated at the same dose. This suggests that blocking the 6-position of the benzoxazole ring mitigated potential toxicity, possibly by preventing the formation of reactive metabolites. [1]

| 其他信息 |
FT113 is a novel piperazine-based inhibitor of fatty acid synthase (FASN), a key enzyme in the de novo lipogenesis pathway which is upregulated in many cancers. [1]
The compound was designed based on structure-activity relationship (SAR) studies and insights from a co-crystal structure of a related analog (compound 22) bound to the FASN KR domain. The structure reveals key hydrogen bond interactions with Ser2021, Gln2031, and Tyr2034, and a π-interaction between the cyclopropyl group and the NADPH cofactor. [1] FT113 features a 6-fluorobenzoxazole moiety on the right-hand side and a 1-hydroxycyclopropane-1-carboxamide group on the left-hand side of the piperazine core. The 6-fluoro substitution was crucial for improving tolerability. [1] The synthesis of FT113 is described in Scheme 1, starting from methyl 4-(chlorocarbonyl)benzoate and 2-amino-5-fluorophenol, involving condensation, saponification, amide coupling, deprotection, and a final amide coupling step. [1] The compound served as a tool molecule to establish proof-of-concept for FASN inhibition in models of DNL-driven disease. [1] |
