Sinomenine (Coculine; Cucoline; Kukoline) is a naturally occuring alkaloid found in the root of the climbing plant Sinomenium acutum which is native to Japan and China. It is traditionally used in herbal medicine in these countries, as a treatment for rheumatism and arthritis. However, its analgesic action against other kinds of pain is limited. Sinomenine is a morphinan derivative, related to opioids such as levorphanol and the non-opioid cough suppressant dextromethorphan.

Biological Activity
| ln Vitro | Tanshinone IIA has anti-tumor properties such as increasing tumor cell death, decreasing short-term cell proliferation, altering the tumor cell cycle, and so on. Tanshinone IIA demonstrates anti-tumor actions on A549 cells; at 24, 48, and 72 hours, the IC50 of tanshinone IIA was 145.3, 30.95, and 11.49 μM, respectively. The proliferative activity of A549 cells treated with tanshinone IIA (2.5 - 80 μM) for 24, 48, and 72 hours, respectively, was assessed using the CCK-8 assay. The CCK-8 results shown that tanshinone IIA may, in a dose- and time-inhibitory manner, strongly suppress the growth of A549 cells. After 48 days of medication therapy, significant reduction of A549 cell growth and concentration was detected (concentration trace IC50 values used: Tanshinone IIA 31 μM vs. A549). Using Western blotting, it was discovered that both drug-treated groups expressed VEGF and VEGFR2 48 hours after subjecting A549 cells to tanshinone IIA (31 μM) as opposed to the vehicle [1]. The most prevalent ingredient in Salvia miltiorrhiza root is tanshinone IIA. Tanshinone IIA H9C2 cells express transcribed PTEN (phosphatase and tensin homolog), a protein that functions in cells, which causes angiotensin II-induced cellular fluorescence. important impediment. By phosphorylating phosphatase and tensin homolog (PTEN) expression, tanshinone IIA suppresses cytokines that are produced by angiotensin II (AngII) [2]. Tanshinone IIA promotes PI3K/Akt/mTOR luster and decreases the expression of the EGFR and IGFR proteins in AGS cells [3]. |
| ln Vivo | The cognitive impairment caused by scopolamine is significantly reversed by tanshinone IIA (10 or 20 mg/kg; sidewall) [4]. By blocking PERK signaling, tanshinone IIA (2, 4, 8 mg/kg; i.p.) may reduce endoplasmic reticulum daytime, which may be linked to the mediated protective effect on STZ-induced diabetic nephropathy [5]. Ectopic protein intima development is markedly inhibited by tanshinone IIA (3 and 12 mg/kg; ip) [6]. |
| Animal Protocol |
Animal/Disease Models: Male ICR mice (25–30 g)[4] Doses: 10 or 20 mg/kg Route of Administration: Oral Experimental Results:Dramatically reversed scopolamine-induced cognitive impairment. Animal/Disease Models: STZ-treated rats [5] Doses: 2, 4, 8 mg/kg Route of Administration: intraperitoneal (ip) injection Experimental Results: diminished expression levels of transforming growth factor-β1, TSP-1, Grp78 and CHOP, and attenuated protein increased the levels of p-PERK, p-elf2α and ATF-4 in the renal tissue of diabetic rats. Animal/Disease Models: Female SD (SD (Sprague-Dawley)) rats (180 -200g) [6] Doses: 3 and 12 mg/kg Route of Administration: intraperitoneal (ip) injection Experimental Results: Dramatically inhibited the growth of ectopic endometrium. |
| Toxicity/Toxicokinetics |
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. |

| Additional Infomation |
1,6,6-trimethyl-8,9-dihydro-7H-naphtho[1,2-g]benzofuran-10,11-dione is an abietane diterpenoid. Tanshinone IIA has been reported in Salvia miltiorrhiza, Salvia glutinosa, and other organisms with data available. See also: Salvia Miltiorrhiza Root (part of). 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. |
