| In Vitro | Gimatecan (3 to 300 ng/mL) significantly inhibits the growth of human bladder cancer models (HT1376 and MCR), thus reflecting antiproliferative potency[1]. Gimatecan causes a persistent S-phase arrest At 0.003 µg/mL and the number of S-phase cells increased after treatment with a higher concentration (0.03 µg/mL)[1]. Cell Proliferation Assay[1] Cell Line: HT1376 cells harbor a p53 mutation; MCR cells harbor two p53 mutations: one in exon 4 (CGC→CCC) and one in exon 9 (CAG→TAG) Concentration: 3 to 300 ng/mL Incubation Time: 1, 6, and 24 hours Result: IC50s of 90±3 and 9.0±0.4 ng/mL for MCR and HT1376 cells after treatment for 1 hours. IC50s of 5.0±0.2 and 2.8±0.1 ng/mL for MCR and HT1376 cells after treatment for 24 hours. The growth-inhibitory effect was dose-dependent and time-dependent. HT1376 cells were more sensitive than MCR cells at least following a short-term exposure. |
| In Vivo | Gimatecan (2 mg/kg; treatment per os, every fourth day for four times) is effective for inhibiting tumor growth[1]. Animal Model: Athymic Swiss nude mice bearing HT1376 model[1] Dosage: 2 mg/kg Administration: Treatment per os, every fourth day for four times Result: Caused a marked tumor growth inhibition during treatment. |
