| In vitro | TL033 TFA exhibits cytotoxic activity against HCC1806 cells (breast cancer cell line) over a 3-day period, with an EC₅₀ of 13.15 nM. |
| In vivo | TL033 TFA (administered intravenously at 3 mg/kg twice a week for a total of six doses) effectively inhibits tumor growth in a mouse xenograft model of NCI-N87 gastric cancer, resulting in tumor regression by the end of treatment. Additionally, TL033 TFA (administered intravenously as a single dose of 10 mg/kg) demonstrates significant tumor tissue targeting and favorable pharmacokinetics. |
