In vitro |
METHODS: Eight TNBC cell lines were treated with Camptothecin (0.1-5 µM) for 72 h. Cell viability was measured by PrestoBlue. RESULTS: Camptothecin inhibited the cell viability of MCF7, HCC1428, HCC1419, HCC202, MDA453, MDA231, Sum149, and BT549 cells, with IC50 values of 0.089/0.448/0.067/0.481/0.058/0.040/0.065/ 0.056 µM.[1]. METHODS: Lung cancer cells H1299 and H460 were treated with Camptothecin (0.5-5 µM) for 16 h. Cell migration was detected by wound-healing assay. RESULTS: Camptothecin inhibited the migration of H1299 and H460 cells without a dose-dependent effect. [2] |

METHODS: To assay antitumor activity in vivo, Camptothecin (0.15-1.2 mg/kg) and doxorubicin (0.25-2 mg/kg) were intravenously injected into athymic nu/n mice bearing triple-negative mammary carcinoma tumors, MDA-MB-231, every two days for four administrations. RESULTS: A dose-dependent reduction in tumor growth was observed, with a 40.8% reduction at 0.5 mg/kg DOX + 0.3 mg/kg CPT and a 93% reduction at 1.5 mg/kg DOX + 0.9 mg/kg CPT. The highest dose tested (2 mg/kg DOX + 1.2 mg/kg CPT) completely stopped tumor growth on day 44. [3] METHODS: To study the effects on obesity, Camptothecin (1 mg/kg, 0.1% Tween 80) was administered orally to obese mice once daily for three days. RESULTS: Oral administration of Camptothecin increased circulating GDF15 levels in diet-induced obese (DIO) mice and genetic ob/ob mice. Consistent with the anorectic effects of GDF15, Camptothecin inhibited food intake, thereby reducing body weight, blood glucose, and liver fat content in obese mice. [4] |
