Son of sevenless homolog 1 (SOS1) is a key regulator of KRAS to modulate KRAS from inactive to active states. Herein, we disclosed efficacy-improving tetra-cyclic quinazoline derivatives as an enhanced scaffold for inhibiting the SOS1–KRAS interaction. Compound 37, which conjugated 1-carbonitrile-cyclopropane to tetra-cyclic quinazoline, showed a twofold higher oral drug exposure and 2.5-fold longer
KRAS 突变(G12C、G12D 等)与许多难治性癌症的发生和发展有关。Son of sevenless homolog 1 (SOS1) 是 KRAS 的关键调节因子,可将 KRAS 从非活性状态调节为活性状态。在此,我们公开了提高功效的四环喹唑啉衍生物作为抑制 SOS1-KRAS 相互作用的增强支架。将 1-腈-环丙烷与四环喹唑啉缀合的化合物37在 CD-1 小鼠血浆中表现出比 BI-3406 高两倍的口服药物暴露和长 2.5 倍的半衰期。在 Mia-paca-2 异种移植模型中,单独给药37抑制了 71% 的肿瘤生长。临床前研究表明,37对 CYP 和 hERG 的抑制有限。总的来说,我们的研究表明37是治疗 KRAS 驱动的癌症的有前途的候选药物。
