在几种癌细胞系中，TIC10 以不依赖于 p53 的方式诱导 TRAIL 蛋白在细胞表面定位，并以剂量依赖的方式增加 TRAIL mRNA。虽然 TIC10 在体外表现出广谱抗肿瘤活性，并导致 TRAIL 敏感的 HCT116 p53/p53 细胞表现出指示细胞死亡的亚 G1 DNA 含量增加，但正常成纤维细胞在同等剂量下不受 TIC10 影响。 TIC10 可以保护健康的成纤维细胞，同时减少癌细胞系的克隆存活。与 TRAIL 介导的细胞凋亡类似，TIC10 以不依赖 p53 且依赖 Bax 的方式增加癌细胞中亚 G1 DNA 的比例。 TIC10引起的TRAIL上调依赖于Foxo3a，Foxo3a也会上调TRAIL死亡受体DR5和其他靶标，可能使一些TRAIL耐药的肿瘤细胞变得敏感。 ERK 和 Akt 激酶被 TIC10 灭活，导致 Foxo3a 进入细胞核并与 TRAIL 启动子结合以激活基因转录。 Foxo3a 然后被转运到细胞核中。有效的抗肿瘤药物 TIC10 通过增加肿瘤细胞及其周围组织中天然存在的肿瘤抑制因子 TRAIL 的水平来发挥作用。 [1]

当TIC10和TRAIL以多剂量给药时，TIC10和TRAIL治疗导致HCT116 p53−/−异种移植物中的肿瘤消退到相当的程度。 TIC10 还诱导 MDA-MB-231 人三阴性乳腺癌异种移植物消退，而 TRAIL 治疗的肿瘤则进展。在 DLD-1 结肠癌异种移植物中，TIC10 在治疗一周后诱导肿瘤停滞，而 TRAIL 治疗的肿瘤在单剂量后进展。 SW480异种移植物在接受单剂量TIC10后也表现出持续的消退，无论该药物是口服还是腹膜内给药，都可以看到这种效果。这表明 TIC10 具有良好的口服生物利用度。 TIC10 通过 TRAIL 介导的直接效应和旁观者效应引起肿瘤特异性细胞死亡。 TIC10 是一种针对原位人多形性胶质母细胞瘤的有效抗肿瘤剂。 [1]

Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)
*Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution.
Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline)
Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil)
Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).
