| In vitro | BT001021 exhibits cytotoxicity against HCC1806 cells (a breast cancer cell line) with an EC50 of 13.15 nM over 3 days. |
| In vivo | BT001021, administered via intravenous injection at 3 mg/kg twice weekly for six doses, effectively suppresses tumor growth in the NCI-N87 gastric cancer xenograft mouse model, leading to tumor regression by the end of treatment. Additionally, a single 10 mg/kg dose of BT001021 (intravenous injection) demonstrates significant tumor tissue targeting and favorable pharmacokinetic properties. |
