Tanshinone I is a diterpene with anticancer, antidiabetic, and neuroprotective properties. It inhibits proliferation in a variety of cancer cell lines, including KB/VCR, MCF-7/ADR, and K562/A02 multidrug resistance cell lines. It inhibits topoisomerase I- and topoisomerase II-mediated supercoiled DNA relaxation activity and inhibits proliferation of H358-IR and H157-IR radioresistant lung cancer cells. It reduces plasma levels of total cholesterol, triglycerides, LDL, and nonesterified fatty acids and decreases blood glucose levels in a rat model of type 2 diabetes induced by streptozotocin and a high-fat diet. Tanshinone I reduces the LPS-induced expression of TNF-α, IL-1β, and IL-6 in microglia. It is neuroprotective in a mouse model of Parkinson’s disease induced by MPTP, preventing dopaminergic cell death in the striatum and improving motor function.

How to use

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. Tanshinone I inhibits PGE2 formation from LPS-induced RAW macrophages (IC50 = 38 μM). However, this compound does not affect COX-2 activity or COX-2 expression. Tanshinone I is an inhibitor of type IIA human recombinant phospholipase A2 (PLA2) with IC50 of 11 μM. In preliminary data, tanshinone I possesses the strongest inhibitory effect on tumor necrosis factor-α (TNF-α)-induced adhesion molecules.
