Tanshinone IIA (Tan IIA), an active component derived from Salvia miltiorrhiza root, has been used to treat various ischemic cardiovascular and cerebrovascular diseases. However, its impact on hepatic ischemia/reperfusion (I/R) injury remains unclear. Here, we addressed this issue by using a 90-minute partial liver ischemia model. Mice were administered Tan IIA intragastrically for 3 days befor...

Purpose: To study the potential neuroprotective effects of tanshinone IIA, a diterpene quinone, in an experimental model 1-methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine (MPTP)-induced Parkinson disease (PD).
 Methods: Mice (C57BL/6) were administered freshly-prepared MPTP at dose 20 mg/kg body weight intraperitoneally, 4 times 2-h intervals, to induce PD. Doses 12.5, 25 and 50 IIA mice as ...

Tanshinone IIA (Tan IIA) is a pharmacologically active substance extracted from the rhizome of Salvia miltiorrhiza Bunge (also known as the Chinese herb Danshen), and is widely used to treat atherosclerosis. The pregnane X receptor (PXR) is a nuclear receptor that is a key regulator of xenobiotic and endobiotic detoxification. Tan IIA is an efficacious PXR agonist that has a potential protectiv...

OBJECTIVES This study investigated the protective effect of tanshinone IIA sodium sulfonate (TSS) on ischemia-reperfusion (I/R) induced cardiac injury, and the underlying mechanism of action. MATERIALS AND METHODS Male Sprague-Dawley rats were subjected to a 30-min coronary arterial occlusion followed by 24 hours' reperfusion. Half an hour before the left coronary artery ligation, rats were p...
