Kaempferol 3,7,4'-trimethyl etHER 是一种黄酮醇苷元，从Siparuna gigantotepala中分离得到，具有抗氧化作用。

Kaempferol 3,7,4'-trimethylether shows selective cyctoxic activities against the nine tested cancer cell lines.

The IC50 values below or around 30 μg/mL were recorded with A. arundinaceum extract against eight of the nine tested cancer cell lines. This extract displayed IC50 values below 40 μg/mL towards the nine tested cancer cell lines whilst A. polyanthum extract, Kaempferol 3,7,4'-trimethylether showed selective activities. Collateral sensitivity (hypersensitivity) was observed with A. arundinaceum extract towards leukemia CEM/ADR5000 cells and glioblastoma U87MG.ΔEGFR compared to their respective sensitive counterparts CEM/CEM and U87MG.[1]
