Thymoquinone is an orally active natural product isolated from Nigella glandulifera. Thymoquinone downregulates the VEGFR2-PI3K-Akt pathway, inhibits the expression of NF-κB and MMP-9, downregulates TWIST1 expression, and activates the Nrf2 pathway to exert various biological activities. Thymoquinone can be used in research related to Alzheimer's disease, cancer, cardiovascular diseases, infectious diseases, and inflammation[1-4].
In vitro, Thymoquinone (25–100μM) was used to treat the human breast cancer cell line MCF-7 for 12–72 hours. Thymoquinone significantly inhibited cell proliferation, induced apoptosis, and caused S-phase and G2-phase cell cycle arrest[5]. Thymoquinone (20μM) was used to treat the colorectal cancer cell lines RKO and SW1116 for 24 hours. In RKO cells, Thymoquinone significantly induced DNA fragmentation, caspase activation, and upregulation of pro-apoptotic genes. In SW1116 cells, Thymoquinone significantly inhibited caspase activity and induced caspase-independent necrotic cell death[6].
In vivo, Thymoquinone (100mg/kg/day) was administered by gavage to LDL-R-/- mice for 8 weeks. Thymoquinone significantly alleviated hyperlipidemia-induced liver injury[7]. Thymoquinone (20mg/kg and 40mg/kg; three times per week) was administered via intraperitoneal injection to C57BL/6J mice for one month. Thymoquinone (40mg/kg) significantly improved age-related hearing loss[8].

Thymoquinone是一种从黑种草籽中分离得到的口服活性天然产物。Thymoquinone可下调VEGFR2-PI3K-Akt通路、抑制NF-κB和MMP-9的表达、下调TWIST1表达并激活Nrf2通路以发挥多种生物活性。Thymoquinone可用于阿尔茨海默病、癌症、心血管疾病、感染病和炎症等方面的相关研究[1-4]。
在体外，Thymoquinone（25–100μM）处理人类乳腺癌细胞系MCF-7 12–72小时。Thymoquinone显著抑制细胞增殖，诱导细胞凋亡，并导致S期和G2期细胞周期阻滞[5]。Thymoquinone（20μM）处理结直肠癌细胞系RKO和SW1116，24小时。在RKO细胞中，Thymoquinone显著诱导DNA片段化、caspase激活和促凋亡基因上调。在SW1116细胞中，Thymoquinone显著抑制caspase活性并诱导caspase非依赖性坏死性细胞死亡[6]。
在体内，Thymoquinone（100mg/kg/day）通过灌胃给药，用于处理LDL-R-/-小鼠，持续8周。Thymoquinone显著减轻了高血脂引起的肝损伤[7]。Thymoquinone（20mg/kg和40mg/kg；每周三次）腹腔注射C57BL/6J小鼠，持续一个月。Thymoquinone（40mg/kg）显著改善了年龄相关性听力损失[8]。
| Cell experiment [1]: | |
Cell lines | MCF-7 cells (human breast cancer cell line) |
Preparation Method | MCF-7 cells were maintained in RPMI 1640 medium supplemented with 10% heat-inactivated fetal bovine serum and penicillin/streptomycin at 37°C in a humidified 5% CO₂ atmosphere. MCF-7 cells were treated with Thymoquinone (25μM). |
Reaction Conditions | 25μM; 12-72h |
Applications | Thymoquinone significantly inhibited cell proliferation, induced apoptosis, and caused S-phase arrest. |

Animal models | LDL-R-/- mice |
Preparation Method |
|
Dosage form | 100mg/kg/day; oral gavage; 8 weeks |
Applications | Thymoquinone administration significantly reduced liver histological alterations induced by hyperlipidemia. Thymoquinone mitigated hyperlipidemia-induced liver injury as indicated by the suppression of metabolic characteristics (TC, TG, and LDL-c), liver biochemical parameters (ALT, AST, and ALP), pyroptosis indicators (NLRP3, IL-1β, and IL-18), a macrophage marker (CD68), and the phosphatidylinositide 3-kinase signaling pathway. |
