The development of a series of potent and highly selective casein kinase 1δ/ε (CK1δ/ε) inhibitors is described. Starting from a purine scaffold inhibitor (SR-653234) identified by high throughput screening, we developed a series of potent and highly kinase selective inhibitors, including SR-2890 and SR-3029, which have IC50 ⩽ 50 nM versus CK1δ. The two lead compounds have ⩽100 nM EC50 values in MTT
描述了一系列有效且高度选择性的酪蛋白激酶 1δ/ε (CK1δ/ε) 抑制剂的开发。从通过高通量筛选鉴定的嘌呤支架抑制剂 (SR-653234) 开始,我们开发了一系列强效且高激酶选择性的抑制剂,包括 SR-2890 和 SR-3029,与 CK1δ 相比,其 IC 50 ⩽ 50 nM。这两种先导化合物在针对人 A375 黑色素瘤细胞系的 MTT 测定中具有 ⩽100 nM EC 50值,并且具有适合用于针对人癌细胞系的原理动物异种移植研究的物理、体外和体内 PK 特性。
