Cirsimaritin is a dimethoxy flavonoid found in plants, it has anticancer potential and shows potent antimicrobial, antioxidant, antispasmodic, activity, and also inhibits cyclooxygenase-1[1-3].
Cirsimaritin significantly decreased cell proliferation in the NCIH-520 cell line, with an IC50 value of 23.29 ± 3.51µM[4]. Cirsimaritin(0–120µg/mL; 20h) inhibited interleukin-6, tumor necrosis factor-α, and NO production in a concentration-dependent manner in lipopolysaccharide (LPS)-stimulated RAW264.7 cells[5]. Cirsimaritin(5-20µg/mL) reduced viral titers and influenza A virus (IAV) RNA and protein synthesis in a dose-dependent manner[6].
Cirsimaritin(10mg/kg; i.g)ffectively prevented DSS-induced colon inflammation in mice by mitigating mucosal damage and inflammatory cell infiltration. It significantly downregulated proinflammatory cytokines such as MMP9, NF-κB, COX-2, and iNOS. Additionally, cirsimaritin reversed DSS-induced effects, including weight loss, colon shortening, tissue damage, increased inflammatory cells, and elevated cytokine secretion[7]. Treatment with cirsimaritin(0.5-1mg/kg; p.o; 8 weeks) reduced the severity of liver injury in the experimental mouse model of metabolic dysfunction-associated fatty liver disease (MAFLD) by inhibiting hepatic steatosis, oxidative stress, inflammation, and liver fibrosis[8].

Cirsimaritin是一种存在于植物中的二甲氧基黄酮，具有抗癌潜力，并显示出显著的抗菌、抗氧化、解痉作用，同时还可抑制环氧合酶-1[1-3]。
Cirsimaritin显著抑制了NCIH-520细胞系的增殖，其IC50值为23.29 ± 3.51µM[4]。在脂多糖(LPS)刺激的RAW264.7细胞中，Cirsimaritin(0–120µg/mL; 20h)以浓度依赖的方式抑制了白介素-6（IL-6）、肿瘤坏死因子-α(TNF-α)和一氧化氮(NO)的产生[5]。此外，Cirsimaritin(5–20µg/mL)以剂量依赖的方式降低了病毒滴度，并抑制了甲型流感病毒(IAV)的RNA和蛋白质合成[6]。
Cirsimaritin(10mg/kg; i.g)通过缓解粘膜损伤和炎性细胞浸润，有效预防了DSS诱导的小鼠结肠炎症。它显著下调了MMP9、NF-κB、COX-2和iNOS 等促炎性细胞因子的表达。此外，Cirsimaritin逆转了DSS诱导的体重减轻、结肠缩短、组织损伤、炎性细胞增加以及细胞因子分泌升高等效应[7]。在代谢功能障碍相关脂肪性肝病(MAFLD)实验性小鼠模型中，Cirsimaritin(0.5-1mg/kg; p.o; 8 weeks)通过抑制肝脂肪变性、氧化应激、炎症及肝纤维化，降低了肝损伤的严重程度[8]。
