Casein kinase 1δ/ε have been identified as promising therapeutic target for oncology application, including breast and brain cancer. Here, we described our continued efforts in optimization of a lead series of purine scaffold inhibitors that led to identification of two new CK1δ/ε inhibitors 17 and 28 displaying low nanomolar values in antiproliferative assays against the human MDA-MB-231 triple negative breast cancer cell line and have physical, in vitro and in vivo pharmacokinetic properties suitable for use in proof of principle animal xenograft studies against human cancers.
酪蛋白激酶1δ/ε已被确定为肿瘤学应用(包括乳腺癌和脑癌)中很有前景的治疗靶点。在此,我们描述了我们在优化嘌呤骨架抑制剂先导系列方面的持续努力,这导致鉴定出两种新的CK1δ/ε抑制剂17和28,它们在针对人MDA-MB-231三阴性乳腺癌细胞系的抗增殖试验中显示出低纳摩尔值,并且具有适合用于针对人类癌症的原理验证动物异种移植研究的物理、体外和体内药代动力学特性。
