生物活性

Tanshinone IIA (Tan IIA) is one of the main compositions in the root of red-rooted salvia. Tanshinone IIA may suppress angiogenesis by targeting the protein kinase domains of VEGF/VEGFR2.

IC50 & Target

VEGF/VEGFR2[1]

体外研究
(In Vitro)

The anti-tumor effect of Tanshinone IIA includes inhibiting tumor cell proliferation, disturbing tumor cell cycle, promoting tumor cell apoptosis, and inhibiting tumor cell invasion and transfer. Tanshinone IIA has anti-proliferative effects on A549 cells: the IC50 of Tanshinone IIA after 24, 48 and 72 h are 145.3, 30.95 and 11.49 μM, respectively. The CCK-8 assay is used to evaluate the proliferative activity of A549 cells treated with Tanshinone IIA (2.5-80 μM) for 24, 48 and 72 h, respectively. The CCK-8 results show that Tanshinone IIA can significantly inhibit A549 cell proliferation in a dose- and time-dependent manner. Obvious apoptosis and cell growth inhibition of A549 cells are observed after drug treatment for 48 h (concentrations used are approximately IC50 values: Tanshinone IIA 31 μM on A549). Western blotting finds that 48 h exposures to Tanshinone IIA (31 μM) in A549 cells, downregulates expression of VEGF and VEGFR2 protein in both drug treatment groups vs. vehicle[1]. Tanshinone IIA, one of the most abundant constituents of the root of Salvia miltiorrhiza, protects rat myocardium-derived H9C2 cells against apoptosis. Treatment of H9C2 cells with Tanshinone IIA inhibits angiotensin II-induced apoptosis by downregulating the expression of PTEN (phosphatase and tensin homolog), a tumor suppressor that plays a critical role in apoptosis. Tanshinone IIA inhibits angiotensin II (AngII)-induced apoptosis by downregulating the expression of phosphatase and tensin homolog (PTEN)[2]. Tanshinone IIA decreases the protein expression of EGFR, and IGFR blocking the PI3K/Akt/mTOR pathway in gastric carcinoma AGS cells[3].

生物活性

Tanshinone IIA sulfonate (sodium) is a derivative of tanshinone IIA, which acts as an inhibitor of store-operated Ca2+ entry (SOCE), and is used to treat cardiovascular disorders.

体外研究
(In Vitro)

Sodium Tanshinone IIA sulfonate (12.5 μM) inhibits hypoxia-induced PKG and PPAR-γ downregulation in PASMCs and distal pulmonary arteries of rats. The suppressive effects of Sodium Tanshinone IIA sulfonate on TRPC1 and TRPC6 expression in hypoxic PASMCs can be prevented by specific knockdown PKG or PPAR-γ. The suppressive effects of Sodium Tanshinone IIA sulfonate on basal calcium concentration and SOCE in hypoxic PASMCs can be reversed by specific knockdown of PKG or PPAR-γ. PKG-PPAR-γ signaling axis participates in the suppressive effects of Sodium Tanshinone IIA sulfonate on proliferation in hypoxic PASMCs. PPAR-γ agonist promotes the protective role of Sodium Tanshinone IIA sulfonate on basal [Ca2+]i and SOCE in hypoxic PASMCs[2]. 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[3]. Sodium Tanshinone IIA sulfonate inhibits the activity of CYP3A4 in a dose-dependent manner in the HLMs and CYP3A4 isoform. Sodium Tanshinone IIA sulfonate primarily inhibits the activities of CYP3A4 in vitro, and Sodium Tanshinone IIA sulfonate has the potential to perpetrate drug-drug interactions with other CYP3A4 substrates[4].

体内研究
(In Vivo)

Sodium Tanshinone IIA sulfonate (10 mg/kg, 20 mg/kg) and Donepezil shorten escape latency, increase crossing times of the original position of the platform, and increase the time spent in the target quadrant. Sodium Tanshinone IIA sulfonate decreases the activity of acetylcholinesterase (AChE) and increases the activity of choline acetyltransferase (ChAT) in the hippocampus and cortex of SCOP-treated mice. Sodium Tanshinone IIA sulfonate increases the activity of superoxide dismutase (SOD) and decreases the levels of malondialdehyde (MDA) and reactive oxygen species (ROS) in hippocampus and cortex[1]. Sodium Tanshinone IIA sulfonate prevention (30 mg/kg/day) alleviates hypoxia-induced characteristic changes in chronic hypoxia PH rat model[2]. Sodium Tanshinone IIA sulfonate (20, 10, and 5 mg/kg, i.p.) effectively prevents peritoneal adhesion without affecting anastomotic healing in the rats. Compared with the adhesion model group, the Sodium Tanshinone IIA sulfonate-treated groups show increased peritoneal lavage fluid tPA activity and tPA/PAI-1 ratio in the ischemic tissues with loared TGF-β1 and collagen I expressions in the ischemic tissues[5].

Animal Administration
[1][2]

Mice[1]
Male Kunming mice (KM, weighing 35-40 g) are maintained on standard laboratory conditions with free access to water and food. Mice are randomly divided into five groups: vehicle control group (CON, 0.9% saline, n=10), scopolamine group (SCOP, n=10), low dose Sodium Tanshinone IIA sulfonate group (Sodium Tanshinone IIA sulfonate L, SCOP 3 mg/kg + Sodium Tanshinone IIA sulfonate 10 mg/kg, n=10), high dose Sodium Tanshinone IIA sulfonate group (Sodium Tanshinone IIA sulfonate H, SCOP 3 mg/kg + Sodium Tanshinone IIA sulfonate 20 mg/kg, n=10), and Donepezil group (DON, SCOP 3 mg/kg + ARI 3 mg/kg, n=10). Mice are treated with saline, Sodium Tanshinone IIA sulfonate, and Donepezil, respectively, by gavage, once per day for two weeks. SCOP is injected from the eighth day for one week (intraperitoneally, IP). The SCOP is injected 0.5 h before the Morris water maze test.
Rats[2]
Male Sprague-Dawley rats (200-250 g) are randomly divided into four groups by the random number table: 1) normoxia control group, 2) normoxia + Sodium Tanshinone IIA sulfonate group, 3) hypoxia control group, and 4) hypoxia + Sodium Tanshinone IIA sulfonate group. Groups 1 and 2 are placed in normoxic condition and groups 3 and 4 in a hypoxic cabin with normal pressure, as previously reported, where the oxygen concentration is maintained at 10±1%, in a sustained hypoxic condition for 21 days. Groups 2 and 4, starting from the first day of hypoxia, are, respectively, intraperitoneally injected with 30 mg/kg tanshinone IIA sulfonate; meanwhile, groups 1 and 3 receive the same dose of saline.

生物活性

Escin IIa, isolated from horse chestnut, the seeds of Aesculus hippocastanum L., has positive effects on acute inflammation in animals. Escin IIa has gastroprotections on ethanol-induced gastric mucosal lesions in rats[1][2].

体内研究
(In Vivo)

Escins Ia, Ib, IIa, and IIb (50-200 mg/kg) inhibits the increase of vascular permeability induced by both acetic acid in mice and histamine in rats. Escins Ib, IIa, and IIb (50-200 mg/kg) also inhibit that induced by serotonin in rats, but escin Ia didn’t. Escins Ia, Ib, IIa, and IIb (200 mg/kg) inhibit the hind paw edema induced by carrageenin at the first phase in rats. Escin Ia (200 mg/kg) and escins Ib, IIa, and IIb (50-200 mg/kg) inhibit the scratching behavior induced by compound 48/80 in mice, but escin Ia was weakest[1].
Escin IIa (10-50 mg/kg;p.o.;) potently inhibits ethanol-induced gastric mucosal lesions[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Male Sprague–Dawley rats (Ethanol-induced gastric mucosal lesions in rats)[1]
Dosage: 10-50 mg/kg
