Tetrahydro tanshinone I is one compound of Fufang Danshen Prescription (FDP) , liposome equilibrium dialysis system could simply and effectively esti-mate the absorption of multiple components in FDP in vivo, and predicts the potential bioactivity of thes
Isotanshinone I with IC50s of 1.13 μM and 0.432 μM for α-glucosidase and AGE, respectively. Isotanshinone I has inhibitory activity against α-glucosidase and formation of AGE,
Isotanshinone IIA, could non-competitively inhibit Protein Tyrosine Phosphatase 1B (PTP1B) activity with an IC50 0f 11.4 μM. is an abietane-type diterpene metabolite.
Dihydroisotanshinone I has protective action against menadione-induced hepatotoxicity, attributed to its antioxidant properties including the free radical scavenging activity and inhibition of lipid peroxidation.
Co-treatment with Tanshinone IIB (TSB) significantly inhibits the DNA laddering, cytotoxicity and apoptosis of rat cortical neurons induced by staurosporine in a concentration-dependent manner; TSB also suppresses the elevated Bax protein and decreased bc
Hydroxytanshinone ⅡA has good antiproliferative effect on SGC-7901,HeLa, and HepG 2 cell, the values of IC50 are 4.18, 6.08 and10.20 uM, respectively; it has tumor cell proliferation inhibition significantly stronger than the tanshinoneⅡA.
