A novel series of pyrazolo[3,4-c]isoquinoline derivatives was discovered as B-RafV600E inhibitors through scaffold hopping based on a literature lead PLX4720. Further SAR exploration and optimization led to the discovery of potent B-RafV600E inhibitors with good oral bioavailability in rats and dogs. One of the compounds EBI-907 (13g) demonstrated excellent in vivo efficacy in B-RafV600E dependent
通过基于文献铅PLX4720的脚手架跳跃,发现了一系列新颖的吡唑并[3,4- c ]异喹啉衍生物作为B-Raf V600E抑制剂。进一步的SAR探索和优化导致发现了在大鼠和狗中具有良好口服生物利用度的有效B-Raf V600E抑制剂。化合物EBI-907(13g)在小鼠中依赖B-Raf V600E的Colo-205肿瘤异种移植模型中表现出出色的体内功效,并且正在临床前研究中用于治疗黑素瘤和与B-Raf V600E相关的癌症。
