CVM-05-002 is a potent and selective inhibitor of PI5P4Ks, and a 1.7 Å X-ray structure reveals its binding interactions in the ATP-binding pocket. Further investigation of the structure-activity relationship led to the development of compound 13, replacing the rhodanine-like moiety present in CVM-05-002 with an indole, a potent pan-PI5P4K inhibitor with excellent kinome-wide selectivity. Finally, we employed
由于它们在许多重要的信号传导途径中的作用,磷脂酰肌醇5-磷酸4激酶(PI5P4Ks)是开发针对癌症,代谢和免疫疾病的实验性疗法的有吸引力的目标。开发针对这些脂质激酶的小分子抑制剂的最新努力导致化合物具有低至亚微摩尔的效力。在这里,我们报告了针对我们内部激酶抑制剂库的PI5P4Kα高通量筛选方法,鉴定了CVM-05-002。CVM-05-002是一种有效且选择性的PI5P4Ks抑制剂,其1.7ÅX射线结构揭示了其在ATP结合袋中的结合作用。对结构活性关系的进一步研究导致了化合物13的开发,用吲哚取代了CVM-05-002中存在的若丹丹样部分,一种有效的泛PI5P4K抑制剂,具有优异的全基因组选择性。最后,我们采用等温细胞热位移试验(CETSAs)来证明抑制剂在HEK 293T细胞中有效地靶向PI5P4Kα和-β。
