Tanshinone IIA sulfonate sodium is a water-soluble derivative of tanshinone IIA, which acts as an inhibitor of store-operated Ca2+entry (SOCE), and is used to treat cardiovascular disorders.
Tanshinone IIA Sulfonate Sodium (STS) is a derivative of tanshinone IIA, which acts as an inhibitor of store-operated Ca2+ entry (SOCE), and is used to treat cardiovascular disorders. Morris water maze results showed that oral administration of STS (10 mg/kg and 20 mg/kg) and Donepezil shortened escape latency, increased crossing times of the original position of the platform, and increased the time spent in the target quadrant. STS decreased the activity of acetylcholinesterase (AChE) and increased the activity of choline acetyltransferase (ChAT) in the hippocampus and cortex of SCOP-treated mice[3]. Sodium Tanshinone IIA sulfonate (12.5 μM) inhibits hypoxia-induced PKG and PPAR-γ downregulation in PASMCs and distal pulmonary arteries of rats[4]. Sodium tanshinone IIA sulfonate inhibits the activity of CYP3A4 in a dose-dependent manner by the HLMs and CYP3A4 isoform. The KM and Vmax values of STS are 54.8±14.6 µM and 0.9±0.1 nmol/mg protein/min, respectively, for the HLMs and 7.5±1.4 µM and 6.8±0.3 nmol/nmol P450/min, respectively, for CYP3A4. CYP1A2, CYP2A6, CYP2C9, CYP2D6, CYP2E1, and CYP2C19 show minimal or no effects on the metabolism of STS[5]. STS significantly ameliorated pulmonary inflammatory responses, mucus hypersecretion and lung function decline in CS-exposed mice challenged with LPS. STS treatment also significantly attenuated increased IL-6 and IL-8 releases from cigarette smoke extract (CSE)-treated human bronchial epithelial cells (16HBE) challenged with LPS[6]. Intermittent hypoxia treatment resulted in high oxidative stress and low apoptosis in Lewis lung carcinoma-implanted mice, which could be attenuated by sodium tanshinone IIA sulfonate administration possibly through a mechanism mediated by the nuclear factor erythroid 2-related factor 2/nuclear factor kappa B signaling pathway[7].
