Biological Activity
Tanshinone IIB (TSB) is a major active constituent of the roots of Salvia miltiorrhiza (Danshen) widely used in the treatment of stroke and coronary heart disease in Asian countries; TSB significantly reduces the DNA laddering caused by staurosporine in a concentration-dependent manner, also suppresses the elevated Bax protein and decreased bcl-2 and caspase-3 proteins induced by staurosporine in rat cortical neurons, indicates that TSB has a neuroprotective effect via inhibition of apoptosis.[1]
TSB significantly inhibits the uptake of digoxin and vinblastine in membrane vesicles containing PgP or MRP1, also moderately stimulates PgP ATPase activity, indicates that TSB is a substrate for PgP and MRP1 and that drug resistance to TSB therapy and drug interactions may occur through PgP and MRP1 modulation.[2]
