The modification of natural or semisynthetic triterpenoids with amines can be explored as a promising strategy for improving their pharmacological properties. Here, we report the design and synthesis of 11 novel amide derivatives of soloxolone methyl (), a cyano enone-bearing derivative of 18βH-glycyrrhetinic acid. Analysis of their bioactivities in vitro and in silico revealed their high toxicity against a panel of tumor cells (average IC = 3.7 µM) and showed that the formation of amide moieties at the C-30 position of soloxolone did not enhance the cytotoxicity of derivatives toward tumor cells compared to , though it can impart an ability to pass across the blood-brain barrier. Further HPLC-MS/MS and mechanistic studies verified significant brain accumulation of hit compound (soloxolone tryptamide) in a murine model and showed its high anti-glioblastoma potential. It was found that induced ROS-dependent and autophagy-independent death of U87 and U118 glioblastoma cells via mitochondrial apoptosis and effectively blocked their clonogenicity, motility and capacity to form vessel-like structures. Further in vivo study demonstrated that intraperitoneal injection of at a dosage of 20 mg/kg effectively inhibited the growth of U87 glioblastoma in a mouse xenograft model, reducing the proliferative potential of the tumor and leading to a depletion of collagen content and normalization of blood vessels in tumor tissue. The obtained results clearly demonstrate that can be considered as a promising leading compound for drug development in glioblastoma treatment.
探索用胺修饰天然或半合成三萜类化合物作为改善其药理性质的一种有前景的策略。在此,我们报道了11种新型的索罗索龙甲酯()酰胺衍生物的设计与合成,索罗索龙甲酯是18βH-甘草次酸的一种含氰基烯酮衍生物。对其体外和计算机模拟生物活性的分析揭示了它们对一组肿瘤细胞具有高毒性(平均IC = 3.7 μM),并且表明与相比,在索罗索龙的C-30位形成酰胺部分并没有增强衍生物对肿瘤细胞的细胞毒性,尽管它能赋予穿过血脑屏障的能力。进一步的HPLC-MS/MS和机制研究证实了命中化合物(索罗索龙色胺)在小鼠模型中显著的脑内蓄积,并显示出其高抗胶质母细胞瘤潜力。发现通过线粒体凋亡诱导U87和U118胶质母细胞瘤细胞的ROS依赖性和自噬非依赖性死亡,并有效阻断它们的克隆形成能力、运动能力和形成血管样结构的能力。进一步的体内研究表明,以20 mg/kg的剂量腹腔注射在小鼠异种移植模型中有效抑制了U87胶质母细胞瘤的生长,降低了肿瘤的增殖潜力,并导致肿瘤组织中胶原蛋白含量减少和血管正常化。所获得的结果清楚地表明,可被认为是胶质母细胞瘤治疗中药物开发的一种有前景的先导化合物。
