| Description | Namitecan is an effective inhibitor of topoisomerase I. It has antitumor property. |
| In vitro | Namitecan decreases a dose-dependent decrease in EGFR expression in the different cell lines[1]. Namitecan and cetuximab cooperate in inhibiting EGFR expression. ST1968 causes a comparable level of apoptosis in A431 and A431/TPT cells (IC50: 0.21 and 0.29 μM)[2]. |
| In vivo | Namitecan (10 mg/kg) combined with cetuximab (1 mg/mouse) demonstrates synergistic antitumor effects in SCC models, dependent on the EGFR gene copy number[1]. ST1968 (25 mg/kg) is associated with tolerable body weight loss and no fatal toxicity, achieving a 100% complete response rate in mice with the A431 tumor, and maintaining significant efficacy in topotecan-resistant tumors[2]. |
