Abstract

Achondroplasia (ACH), the most prevalent form of human dwarfism, is caused by the G380R mutation in FGFR3 in approximately 99% of cases. Through structural hybridization of Tyra-300 and LY2874455, we developed compound 23, a new dual-target FGFR2/3 inhibitor demonstrating potent activity against both wild-type and mutant FGFR3. In preclinical ACH mouse models, compound 23 showed a dose-dependent improvement in growth rate, with significantly enhanced efficacy versus infigratinib at equivalent doses. This work presents a new structural scaffold for developing FGFR3 kinase inhibitors to target pathogenic FGFR3 mutations and treat ACH.

发现有效的FGFR2/3抑制剂克服突变抵抗和治疗软骨发育不全。

软骨发育不全（ACH）是人类侏儒症最常见的形式，大约99%的病例是由FGFR3中的G380R突变引起的。通过Tyra-300和LY2874455的结构杂交，我们开发了化合物23，这是一种新的双靶点FGFR2/3抑制剂，对野生型和突变型FGFR3都有有效的活性。在临床前ACH小鼠模型中，化合物23显示出剂量依赖性的生长速度改善，与同等剂量的发炎替尼相比，其疗效显著增强。这项工作提出了一种新的结构支架，用于开发靶向致病性FGFR3突变的FGFR3激酶抑制剂并治疗ACH。
