Luteolin（木犀草素，AbMole，M4589）是一种广泛存在于植物中的黄酮类化合物，具有多种生物活性，包括抑制炎症、抗氧化、抑制肿瘤生长以及抗菌等作用。在细胞实验中，Luteolin在20-40 µM浓度范围内显著抑制肺癌A549细胞的迁移、侵袭以及伪足形成，且对非癌性MRC-5细胞无毒性作用^[1]。此外，Luteolin（CAS No.：491-70-3）在40 µM浓度下可显著减少HT29细胞的存活率，并通过增加活性氧（ROS）水平诱导细胞凋亡^[2]。Luteolin在黑色素瘤研究中，体外细胞模型和体内小鼠模型均表现出抑制肿瘤生长的效果，其作用机制涉及基因组水平的调控^[3]。Luteolin在肺癌小鼠模型中，通过增强T细胞介导的杀伤途径促进肿瘤细胞凋亡，显著抑制肿瘤生长^[4]。Luteolin在抗菌研究中，对金黄色葡萄球菌（包括耐甲氧西林金黄色葡萄球菌MRSA）表现出抑制作用^{[5, 6]}。在神经保护研究中，Luteolin可显著预防β-淀粉样蛋白（Aβ）诱导的PC-12细胞凋亡，并抑制细胞活力下降^[7]。此外，Luteolin在α-葡萄糖苷酶抑制实验中表现出非竞争性抑制机制，其IC₅₀值约为32 µM，显著低于阿卡波糖（815 µM）^[8]。Luteolin在昆虫研究中，在0.1 mg/mL浓度下可显著缩短成虫寿命并降低繁殖力^[9]。这些研究结果表明，Luteolin（木犀草素，AbMole，M4589）在多种细胞（如A549、HT29、PC-12）和动物模型（如小鼠）中具有广泛的科研应用潜力，其作用机制涉及多种信号通路和分子靶点。
