receptor-specific kinase inhibitors hinders therapeutic options for skeletal defects and cancer as a result of an overactivated BMP signaling pathway. By screening 4.17 billion “unbiased” and “kinase-biased” DNA-encoded chemical library molecules, we identified hits CDD-1115 and CDD-1431, respectively, that were low-nanomolar selective kinase inhibitors of BMPR2. Structure–activity relationship studies addressed
为患者发现单激酶选择性抑制剂具有挑战性,因为人类基因组编码的 500 多种激酶共享高度保守的催化结构域。迄今为止,尚未报道针对单一转化生长因子 β (TGFβ) 家族跨膜受体激酶(包括骨形态发生蛋白受体 2 型 (BMPR2))的独特选择性抑制剂。由于 BMP 信号通路过度激活,受体特异性激酶抑制剂的缺乏阻碍了骨骼缺陷和癌症的治疗选择。通过筛选 41.7 亿个“无偏向”和“激酶偏向”DNA 编码化学库分子,我们分别鉴定了命中CDD-1115和CDD-1431,它们是 BMPR2 的低纳摩尔选择性激酶抑制剂。结构-活性关系研究解决了代谢不稳定性和高分子量问题,分别产生了有效的 BMPR2 选择性抑制剂类似物CDD-1281 (IC 50 = 1.2 nM) 和CDD-1653 (IC 50 = 2.8 nM)。我们的工作表明,DNA 编码化学技术 (DEC-Tec) 对于识别新型一流、高效、选择性激酶抑制剂是可靠的。
