BALB/c mice 4T1 breast cancer model Tail vein injection 1 mg/kg (TPZ), 3 mg/kg (BMS) Every 3 days, total of 4 times Evaluate the anti-tumor efficacy of PEI-FA@IR@TPZ/BMS LPs in the 4T1 breast cancer model. Results showed that PEI-FA@IR@TPZ/BMS LPs significantly inhibited tumor growth and reduced lung metastatic nodules. Additionally, the nanoplatform enhanced immune responses, as evidenced by increased CD4+ and CD8+ T cells and decreased Tregs. J Nanobiotechnology. 2024 Sep 12;22(1):558.
BALB/c nude mice Subcutaneous 143B tumor model Tail vein injection 10 mg/kg Injected on days 0, 4, and 8, lasting for 16 days Evaluate the anti-tumor effect of TPZ/PFA@UiO-66@PDA in vivo, results showed that nanoparticles accumulated in the tumor region and effectively inhibited tumor growth. J Nanobiotechnology. 2021 Sep 30;19(1):298
Nude mice HRT18 and Nal1+ xenografted tumors Intraperitoneal injection 144 mg/kg Four consecutive days To evaluate the toxicity and activity of tirapazamine alone or combined with chemotherapeutic agents. Results showed that tirapazamine combined with bleomycin or VP16 significantly increased tumor regrowth delay and cytotoxicity. Br J Cancer. 1996 Jun;73(12):1480-5

Results showed that GPPCT specifically accumulates at tumor sites, effectively inhibits tumor growth and metastasis through the combination of CDT and chemotherapy, with no systemic toxicity J Nanobiotechnology. 2022 Jan 21;20(1):43
C57BL/6 mice B16-F10 melanoma model Intratumoral injection 20 μM TPZ 5 treatments in total, every 2-3 days Evaluate the inhibitory effect of NTP + TPZ combination therapy on melanoma growth, showing significant reduction in tumor volume and increased tumor cell death and necrosis Cells. 2023 Aug 21;12(16):2113
BDF and C3H mice T50/80 mammary carcinoma, SCCVII and RIF-1 tumour models Intraperitoneal injection 25-50 mg/kg Single dose, varying from 30 minutes to 24 hours To evaluate the anti-tumour effect and toxicity to normal bone marrow of tirapazamine in combination with cyclophosphamide. Results showed that tirapazamine at 25 mg/kg combined with cyclophosphamide (100 mg/kg) produced an anti-tumour effect equivalent to a single 150 mg/kg dose of cyclophosphamide alone. However, tirapazamine significantly increased toxicity to bone marrow cells. Br J Cancer. 2000 Apr;82(8):1469-73
HBx transgenic mice Spontaneous HCC model in HBx transgenic mice Tail vein injection 3 mg/kg Single dose, followed for up to 7 days To evaluate the efficacy of TPZ combined with hepatic artery ligation (HAL), results showed nearly complete necrosis (~99%) of HCC.
