Interactions
Protective effects of sodium tanshinone IIA sulphonate against adriamycin-induced lipid peroxidation were investigated. Data showed that treatment with sodium tanshinone IIA sulphonate could prevent mice from decrease in body weight caused by adriamycin. It was found that myocardial lipid peroxidation in sodium tanshinone IIA sulphonate-treated mice was lower compared with that in adriamycin-treated ones. The activities of some endogenous antioxidant enzymes, such as superoxide dismutase, glutathione peroxidase and catalase, were higher in the sodium tanshinone IIA sulphonate group than that in the adriamycin group. In vitro experiments showed that sodium tanshinone IIA sulphonate could inhibit adriamycin-induced mitochondrial lipid peroxidation and swelling. Sodium tanshinone IIA sulphonate could scavenge adriamycin semiquinone free radical in heart homogenate dose-dependently. Thus, protective effects of sodium tanshinone IIA sulphonate may not only be related to its antioxidant activity but also to its regulation of antioxidant enzyme activities in the heart.
Although doxorubicin (DXR) is an effective antineoplastic agent; the serious cardiotoxicity mediated by the production of reactive oxygen species has remained a considerable clinical problem. /The/ hypothesis is that tanshinone IIA sodium sulfonate (TSNIIA-SS), which holds significant affects on cardioprotection in clinic, protects against DXR-induced cardiotoxicity. In vitro investigation on H9c2 cell line, as well as in vivo study in animal model of DXR-induced chronic cardiomyopathy were performed. TSNIIA-SS significantly increased cell viability and ameliorated apoptosis of DXR-injured H9c2 cells using CCK-8 assay and Hoechst 33342 stain respectively. Furthermore, the cardio-protective effects of TSNIIA-SS were confirmed with decreasing ST-interval and QRS interval by electrocardiography (ECG); improving appearance of myocardium with haematoxylin and eosin (H&E) stain; increasing myocardial tensile strength using tension to rupture (TTR) assay and decreasing fibrosis through picric-sirius red staining comparing with those receiving DXR alone. These data have provided the considerable evidences that TSNIIA-SS is a protective agent against DXR-induced cardiac injury.
Although doxorubicin (DXR) is an important antineoplastic agent, the serious toxicity mediated by the production of reactive oxygen species has remained a considerable clinical problem. Our hypothesis is that tanshinone II A sodium sulfonate (TSNIIA-SS), which holds significant effects against oxidative stress, protects against DXR-induced nephropathy. Firstly, the antioxidative effects of TSNIIA-SS were confirmed using oxygen radicals absorbance capacities (ORAC) assay in vitro. Then, DXR nephropathy was induced by repeated DXR treatment and verified by kidney index (20.76 +/- 3.04 mg/mm versus 14.76 +/- 3.04 mg/mm, p < 0.001) and histochemical stain. The mice were randomized into three groups: Control group, DXR group and DXR-TSNIIA-SS group. TSNIIA-SS treatment not only improved DXR lesion identified by histochemical stain, but also regulated the expression of several proteins related with the cytoskeleton, oxidative stress and protein synthesis or degradation detected by two-dimensional electrophoresis (2-DE). These data have provided the evidence that TSNIIA-SS is a protective agent against DXR-induced nephropathy.

Mechanism of Action
Doxorubicin, one of the original anthracyclines, remains among the most effective anticancer drugs ever developed. Clinical use of doxorubicin is, however, greatly limited by its serious adverse cardiac effects that may ultimately lead to cardiomyopathy and heart failure. Tanshinone IIA is the main effective component of Salvia miltiorrhiza known as 'Danshen' in traditional Chinese medicine for treating cardiovascular disorders. The objective of this study was set to evaluate the protective effect of tanshinone IIA on doxorubicin-induced cardiomyocyte apoptosis, and to explore its intracellular mechanism(s). Primary cultured neonatal rat cardiomyocytes were treated with the vehicle, doxorubicin (1 uM), tanshinone IIA (0.1, 0.3, 1 and 3 uM), or tanshinone IIA plus doxorubicin. /The authors/ found that tanshinone IIA (1 and 3 uM) inhibited doxorubicin-induced reactive oxygen species generation, reduced the quantity of cleaved caspase-3 and cytosol cytochrome c, and increased BcL-x(L) expression, resulting in protecting cardiomyocytes from doxorubicin-induced apoptosis. In addition, Akt phosphorylation was enhanced by tanshinone IIA treatment in cardiomyocytes. The wortmannin (100 nM), LY294002 (10 nM), and siRNA transfection for Akt significantly reduced tanshinone IIA-induced protective effect. These findings suggest that tanshinone IIA protects cardiomyocytes from doxorubicin-induced apoptosis in part through Akt-signaling pathways, which may potentially protect the heart from the severe toxicity of doxorubicin.
