Biological Activity

Description Bufalin (BF) is a potent inhibitor of steroid receptor coactivator SRC-3, SRC-1 and Na+/K+-ATPase. Bufalin binds to the subunit α1, α2 and α3 of Na+/K+-ATPase with Kd of 42.5 nM, 45 nM and 40 nM, respectively. Bufalin is a major immunoreactive component isolated from the Chinese medicine Chan Su with anti-cancer activity.
Targets
SRC-3 [2] SRC-1 [2] Na+/K+-ATPase α3 [1]
(Cell-free assay)		 Na+/K+-ATPase α1 [1]
(Cell-free assay)		 Na+/K+-ATPase α2 [1]
(Cell-free assay)
40 nM 42.5 nM 45 nM
In vitro

Bufalin strongly promotes SRC-3 protein degradation and binds directly to the coactivator. Bufalin is able to block cancer cell growth at nanomolar concentrations.[2]
In vivo

When incorporated into a nanoparticle delivery system, bufalin is able to reduce tumor growth in a mouse xenograft model of breast cancer. Bufalin sensitizes cancer cells to other targeted chemotherapeutic agents.[2]
