Tanshinone IIA (Tanshinone B) is a diterpene quinone natural product that targets the protein kinase domain of VEGF VEGFR2. Tanshinone IIA inhibits angiogenesis and exhibits anti-inflammatory, antioxidant, and therapeutic activities against coronary heart disease.

Tanshinone IIA sulfonate sodium (Tanshinone IIA sodium sulfonate) is a water-soluble derivative of tanshinone IIA extracted from Savia miltiorrhiza; a potent negative allosteric modulator of the human purinergic receptor P2X7. Tanshinone IIA sulfonate sodium (12.5 μM) inhibits hypoxia-induced PKG and PPAR-γ downregulation in PASMCs and distal pulmonary arteries of rats.

Tanshinone IIA anhydride is a potent, irreversible inhibitor of human carboxylesterase (CE), exhibiting inhibitory constants (K i values) of 1.9 nM for human CE1 and 1.4 nM for human intestinal CE (hiCE), respectively [1].

Tanshinone I (Tanshinone A), an active principle isolated from the herbal medicine Salvia miltiorrhiza, displays cytotoxicity against tumor cells.
