Natural product evodiamine (Evo) and its synthetic derivatives represent an attractive dual Topo 1/2 inhibitors with broad-spectrum antitumor efficacy. However, the clinical applications of these compounds have been impeded by their poor aqueous solubility. Herein, a series of water-soluble 10-substituted-N(14)-phenylevodiamine derivatives were designed and synthesized. The most potent compound 45 featuring a quaternary ammonium salt fragment achieved robust aqueous solubility and nanomolar potency against a panel of human hepatoma cell lines Huh7, HepG2, SK-Hep-1, SMMC-7721, and SMMC-7721/DOX (doxorubicin-resistant cell). Further studies revealed that 45 could inhibit Topo 1 and Topo 2, induce apoptosis, arrest the cell cycle at the G2/M stage and inhibit the migration and invasion. Compound 45 exhibited potent antitumor activity (TGI = 51.1 %, 10 mg/kg) in the Huh7 xenograft model with acceptable safety profile. In addition, a 21-day long-term dose toxicity study confirmed that the maximum tolerated dose of compound 45 was 20 mg/kg. Overall, this study presented a promising Evo-derived candidate for the treatment of hepatocellular carcinoma.

鉴定一种新的 10-羟基吴茱二胺前药作为有效的拓扑异构酶抑制剂,具有更高的水溶性,用于治疗肝细胞癌



天然产物吴茱萸碱 (Evo) 及其合成衍生物是一种有吸引力的双重 Topo 1/2 抑制剂,具有广谱抗肿瘤功效。然而,这些化合物的临床应用因其水溶性差而受到阻碍。在此,设计并合成了一系列水溶性 10-取代-N(14)-苯盐二胺衍生物。具有季铵盐片段的最有效的化合物 45 对一组人肝癌细胞系 Huh7、HepG2、SK-Hep-1、SMMC-7721 和 SMMC-7721/DOX(阿霉素耐药细胞)具有强大的水溶性和纳摩尔效力。进一步研究显示,45 可抑制 Topo 1 和 Topo 2,诱导细胞凋亡,在 G2/M 期阻滞细胞周期,抑制迁移和侵袭。化合物 45 在 Huh7 异种移植模型中表现出有效的抗肿瘤活性 (TGI = 51.1 %,10 mg/kg),具有可接受的安全性。此外,一项为期 21 天的长期剂量毒性研究证实,化合物 45 的最大耐受剂量为 20 mg/kg。总体而言,本研究提出了一种有前途的 Evo 衍生的治疗肝细胞癌的候选药物。
