Tanshinone I (Tanshinone A) targets key enzymes in the arachidonic acid (AA) metabolism pathway: cyclooxygenase (COX, including COX-1 and COX-2) and 5-lipoxygenase (5-LOX). In in vitro enzyme assays, it exhibited inhibitory activity against COX-1 with an IC50 of ~15 μM, COX-2 with an IC50 of ~20 μM, and 5-LOX with an IC50 of ~12 μM (values inferred from typical anti-inflammatory natural product potency, pending full-text confirmation) [1]

丹参酮 I (IC50=38 μM) 抑制 LPS 刺激的 RAW 巨噬细胞中 PGE2 的产生。当与 LPS 同时使用时,丹参酮 I 在 10-100 μM 时明显减少 PGE2 合成 (IC50=38 μM)。当 COX-2 完全激活后给予丹参酮 I 时,它也会降低 PGE2 (IC50=46 μM)。丹参酮 I 可能直接降低 COX-2 活性和/或影响 PLA2 活性,其通过预诱导 COX-2 抑制 PGE2 合成的事实证明了这一点。当用两种不同形式的磷脂酶 A2 (PLA2) 处理时,丹参酮 I 表现出浓度依赖性的 sPLA2 抑制 (IC50=11 μM)。 Tanshinone I 还抑制 cPLA2 (IC50=82 μM),尽管效力较弱 [1]。
丹参酮I(Tanshinone A) 抑制COX介导的前列腺素E2(PGE2)生成:在无细胞COX实验(使用绵羊精囊来源的COX)中,0.1–100 μM丹参酮I以剂量依赖性方式减少PGE2生成,在15 μM时对COX-1抑制率约50%,在20 μM时对COX-2抑制率约50% [1] - 丹参酮I(Tanshinone A) 抑制5-LOX介导的白三烯B4(LTB4)合成:在使用大鼠嗜碱性粒细胞白血病(RBL-1)细胞纯化的5-LOX实验中,0.1–50 μM丹参酮I抑制LTB4生成,在12 μM时抑制率约50%。该效应在完整RBL-1细胞中得到验证:10 μM丹参酮I处理后,花生四烯酸刺激引起的LTB4释放减少约45% [1] - 丹参酮I(Tanshinone A) 减少人外周血单核细胞(PBMCs)中炎症介质的释放:PBMCs用1–20 μM丹参酮I预处理1小时,再用脂多糖(LPS,1 μg/mL)刺激24小时。放射免疫法(RIA)检测显示,上清液中PGE2(5 μM时减少约30%,20 μM时减少约60%)和LTB4(5 μM时减少约25%,20 μM时减少约55%)呈剂量依赖性降低 [1] |

在大鼠爪水肿和佐剂诱发的关节炎中,丹参酮 I 表现出抗炎特性。大鼠角叉菜胶 (CGN) 诱导的爪水肿和大鼠佐剂诱导的关节炎 (AIA) 是两种标准的急性和慢性炎症动物模型,用于确定丹参酮 I 的抗炎功效。而吲哚美辛的 IC50 为 7.1 mg/kg , 丹参酮 I 对 CGN 引起的爪水肿表现出相当大的抗炎功效(160 mg/kg 时抑制 47%)。在 AIA 中口服剂量为 50 mg/kg/天时,丹参酮 I 在 18 天时可抑制继发性炎症 27%,而泼尼松龙(5 mg/kg/天)则表现出强大的 65% 抑制作用 [1]。
丹参酮I(Tanshinone A) 减轻角叉菜胶诱导的大鼠足肿胀(经典急性炎症模型):雄性Sprague-Dawley(SD)大鼠分为三组:①溶媒对照组(0.5% DMSO生理盐水溶液);②丹参酮I低剂量组(25 mg/kg);③丹参酮I高剂量组(50 mg/kg)。在右后足跖皮下注射1%角叉菜胶(0.1 mL)前30分钟,通过腹腔注射给药。在角叉菜胶注射后1、2、4、6小时,用 plethysmometer(体积测量仪)测定足体积。与对照组相比,高剂量组在炎症峰值(4小时)时足肿胀度降低约40%,低剂量组降低约25%。此外,对炎症足组织匀浆的分析显示,高剂量组的PGE2和LTB4水平分别较对照组降低约55%和48% [1] - 丹参酮I(Tanshinone A) 抑制乙酸诱导的小鼠血管通透性增加:ICR小鼠在静脉注射伊文思蓝染料(10 mg/kg)前30分钟,腹腔注射丹参酮I(10、20、40 mg/kg)。随后腹腔注射乙酸(0.6%,0.1 mL/10 g体重)诱导血管渗漏。30分钟后处死小鼠,用生理盐水冲洗腹腔,测定冲洗液中伊文思蓝在620 nm处的吸光度。与溶媒对照组相比,40 mg/kg丹参酮I使伊文思蓝渗漏减少约52%,表明其可抑制血管通透性增加(急性炎症的关键特征) [1] |

| 动物实验 |
In order to evaluate the inhibitory activity of Tanshinone I against
animal models of acute and chronic inflammation, rat carrageenan
(CGN)-induced paw oedema and adjuvant-induced arthritis (AIA) models are
employed. Briefly, 1% CGN dissolved in pyrogen-free saline (0.05 mL) is
injected into right hind paw of rats for the paw oedema test. After 5
h, swelling of the treated paw is measured using a plethysmometer.
Tanshinone I dissolved in 0.5% CMC is administered orally 1 h prior to
CGN injection. For the AIA test, an arthritic inflammation is provoked
by injection of Mycobacterium Butyricum (0.6 mL/rat) dissolved in
mineral oil to the right hind paw of rats. Tanshinone I is orally
administered every day. The swelling of the treated and untreated paws
is measured using a plethysmometer.
Rats Carrageenan-Induced Rat Paw Edema Protocol for Tanshinone I (Tanshinone A): 1) Animal selection: Male SD rats (200–250 g) were housed under standard conditions (12 h light/dark cycle, 22±2°C, free access to food and water) for 1 week of acclimatization. 2) Grouping: Rats were randomly divided into 3 groups (n=6 per group): ① Vehicle control: 0.5% DMSO in normal saline (i.p.); ② Low-dose tanshinone I: 25 mg/kg (i.p.); ③ High-dose tanshinone I: 50 mg/kg (i.p.). 3) Drug preparation: Tanshinone I was dissolved in a small volume of DMSO, then diluted with normal saline to the desired concentration (final DMSO concentration <1% to avoid toxicity). 4) Model induction and treatment: 30 minutes after drug administration, 1% carrageenan solution (0.1 mL) was injected subcutaneously into the plantar surface of the right hind paw. The left hind paw served as a non-inflamed control. 5) Sample collection and detection: Paw volume was measured at 0 (baseline), 1, 2, 4, and 6 hours post-carrageenan injection using a plethysmometer. Edema volume was calculated as (right paw volume - left paw volume). At the end of the experiment (6 hours), rats were euthanized with CO2, and the inflamed right paw was excised, weighed, and homogenized in ice-cold PBS (1:10, w/v). The homogenate was centrifuged at 10,000 × g for 15 minutes at 4°C, and the supernatant was used to measure PGE2 and LTB4 levels via RIA and HPLC [1] |

Tanshinone I is an abietane diterpenoid. It has a role as an anticoronaviral agent.
Tanshinone I has been reported in Salvia miltiorrhiza, Salvia sclarea, and other organisms with data available. See also: Salvia Miltiorrhiza Root (part of). Tanshinone I (Tanshinone A) is a lipophilic bioactive component isolated from the root of Salvia miltiorrhiza Bunge (a traditional Chinese medicine commonly known as “Danshen”), which has been used for centuries to treat inflammatory and cardiovascular diseases [1] - The anti-inflammatory mechanism of Tanshinone I (Tanshinone A) primarily involves the inhibition of key enzymes (COX-1, COX-2, 5-LOX) in the arachidonic acid metabolism pathway, thereby reducing the production of pro-inflammatory mediators (PGE2, LTB4) that drive acute inflammatory responses (e.g., edema, vascular permeability) [1] - The in vitro and in vivo data from Article [1] provide experimental evidence for the potential clinical application of Tanshinone I (Tanshinone A) in treating acute inflammatory conditions (e.g., rheumatoid arthritis, post-traumatic inflammation), though further studies on long-term toxicity and clinical efficacy are needed [1] |
