Marine natural products are important sources of novel drugs. In this study, we isolated 4-hydroxyphenylacetic acid (HPA) from the marine-derived fungus Y39-2. The antithrombotic activity and mechanism of HPA were reported for the first time. Using a zebrafish model, we found that HPA had a strong antithrombotic activity because it can significantly increase cardiac erythrocytes, blood flow velocity, and heart rate, reduce caudal thrombus, and reverse the inflammatory response caused by Arachidonic Acid (AA). Further transcriptome analysis and qRT-PCR validation demonstrated that HPA may regulate autophagy by inhibiting the PI3K/AKT/mTOR signaling pathway to exert antithrombotic effects.
海洋天然产物是新型药物的重要来源。在这项研究中,我们从海洋来源的真菌 Y39-2 中分离出 4-羟基苯乙酸(HPA)。HPA 的抗血栓活性及其机制尚属首次报道。通过斑马鱼模型,我们发现 HPA 具有很强的抗血栓活性,因为它可以显著增加心脏红细胞、血流速度和心率,减少尾部血栓,并逆转花生四烯酸(AA)引起的炎症反应。进一步的转录组分析和 qRT-PCR 验证表明,HPA 可能通过抑制 PI3K/AKT/mTOR 信号通路来调节自噬,从而发挥抗血栓作用。
