significant portion of gliomas and glioblastomas, it is important that IDH1 inhibitors have to be brain penetrant to treat IDH1-mutant brain tumors. Here we report the efforts to design and synthesize a novel serial of mutant IDH1 inhibitors with improved activity and the blood-brain barrier (BBB) penetration. We show that compound 5 exhibits good brain exposure and potent 2-HG inhibition in a HT1080-derived
异柠檬酸脱氢酶1(IDH1)催化异柠檬酸向α-酮戊二酸的转化,是三羧酸循环(TCA)中的关键酶之一。在多种癌症中,已经发现IDH1中Arg132处的热点突变通过进一步将α-酮戊二酸(α-KG)转化为2-羟基戊二酸(2-HG)来改变IDH1的功能。因为IDH1突变发生在神经胶质瘤和胶质母细胞瘤的大部分中,所以重要的是IDH1抑制剂必须具有渗透性,才能治疗IDH1突变的脑瘤。在这里,我们报告了设计和合成一系列具有改进的活性和血脑屏障(BBB)渗透性的突变IDH1抑制剂的努力。我们显示,在HT1080衍生的小鼠异种移植模型中,化合物5表现出良好的大脑暴露能力和有效的2-HG抑制作用,
