the most fatal solid malignancies worldwide. Evidence suggests that thrombin stimulates tumor progression via fibrin formation and platelet activation. Meanwhile, we also found a correlation between thrombin and HCC through bioinformatics analysis. Dabigatran is a selective, direct thrombin inhibitor that reversibly binds to thrombin. Dabigatran was used as the lead agent in this study, and 19 dabigatran
肝细胞癌(HCC)是全世界最致命的实体恶性肿瘤之一。有证据表明凝血酶通过纤维蛋白形成和血小板活化刺激肿瘤进展。同时,我们还通过生物信息学分析发现了凝血酶与HCC之间的相关性。达比加群是一种选择性直接凝血酶抑制剂,可逆地与凝血酶结合。本研究以达比加群为先导药物,基于对接模式设计合成了19种达比加群衍生物。该衍生物的凝血酶抑制活性略优于达比加群。其前药对凝血酶诱导的血小板聚集具有较强的抑制作用,并在细胞水平上有效拮抗凝血酶诱导的肝癌肿瘤细胞的增殖。此外,裸鼠模型中的肿瘤体积、重量、肺转移和继发性肿瘤发生率均降低。与索拉非尼合用可增加索拉非尼的疗效。该研究为发现基于凝血酶的新的抗HCC机制奠定了基础。可作为抗 HCC 药物先导物用于进一步研究。
