Topotecan HCl 生物活性

描述 Topotecan Hydrochloride (SKF 104864A Hydrochloride) effectively inhibits the proliferation of human glioma cells and glioma stem cells (GSCs) in a dose- and time-dependent manner. An optimal administration concentration of 3 μM is selected based on IC50 values at 24 h. Topotecan Hydrochloride induces cell cycle arrest in G0/G1 and S phases and promotes apoptosis. Additionally, it inhibits cell viability in a dose-dependent manner [1].
体内研究

In the NUB-7 metastatic model, animals from all four groups are sacrificed after 14 days of treatment. Compared to the control group, low dose metronomic (LDM) Topotecan Hydrochloride and TP+Pazopanib (PZ) result in significantly lower liver weights in TP+PZ-treated animals compared to PZ alone. Microscopic tumors are observed in the livers of mice in all groups except TP+PZ, indicating the ability of Topotecan Hydrochloride+PZ to control liver metastasis. In previous dose-response studies, daily oral metronomic Topotecan Hydrochloride (0.5, 1.0, and 1.5 mg/kg) showed greater reduction in microvascular density compared to weekly maximum-tolerated dose regimen (7.5 and 15 mg/kg) in an ovarian cancer model. However, mice treated with 1.5 mg/kg daily oral Topotecan Hydrochloride exhibited decreased food intake and a lesser antitumor effect [2].
