Mechanism of Action

Targets/IC₅₀/Ki	PLA2 11 μM
In vitro	Tanshinone I, an active principle isolated from Salvia miltiorrhiza (Danshen), is structurally similar to tanshinone IIA and may possess similar cytotoxic effects on tumor cells. This compound inhibits PGE₂ formation from LPS-induced RAW macrophages (IC50 = 38 μM). However, this compound does not affect COX-2 activity or COX-2 expression. It is an inhibitor of type IIA human recombinant phospholipase A₂ (PLA₂) with IC50 of 11 μM. In preliminary data, this chemical possesses the strongest inhibitory effect on tumor necrosis factor-α (TNF-α)-induced adhesion molecules.
