Methylenetanshinquinone shows antiplasmodial and antitrypanosomal activity, it is active against both Trypanosoma brucei rhodesiense and Plasmodium falciparum.
Sageone represents a promising anticancer agent against gastric cancer that warrants further study, it synergizes with cisplatin cytotoxicity in SNU-1 human gastric cancer cells.Sageone also shows antiviral activity.
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
Horminone has antimicrobial activity, it can inhibit the protein synthesis in several types of bacteria; it can inhibit the in vitro growth of Trypanosoma cruzi, 30 microM drug concentration producing total inhibition of growth. After administration of plant extracts containing Horminone has possibility of toxic effect.
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.
Isocryptotanshinone inhibits protein tyrosine phosphatase 1B (PTP1B) activity with 50% inhibitory concentration values of 56.1±6.3 μM, PTP1B acts as a negative regulator of insulin signaling, and selective inhibition of PTP1B has served as a potential drug target for the treatment of type 2 diabetes.
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.
