benefit. Herein, we describe the structure-guided optimization of a series of quinazolinone-pyrrolodihydropyrrolone analogs leading to the identification of potent pan-Pim inhibitor 28 with improved potency, solubility, and drug-like properties. Compound 28 demonstrated on-target Pim activity in an in vivo pharmacodynamic assay with significant inhibition of BAD phosphorylation in KMS-12-BM multiple
Pim激酶是组成型活性丝氨酸/苏氨酸激酶的一个家族,它们部分冗余并且调节对细胞生长和存活重要的多种途径。在人类疾病中,这三种Pim亚型的高表达与造血和实体瘤癌症的发展有关,这表明Pim激酶抑制剂可以为患者提供治疗益处。在这里,我们描述了一系列的喹唑啉酮-吡咯二氢吡咯烷酮类似物的结构导向的优化,从而导致了鉴定具有改进的效力,溶解性和类药物性质的有效的泛-Pim抑制剂28。在体内药效学测定中,化合物28在给药后16 h对KMS-12-BM多发性骨髓瘤肿瘤中BAD磷酸化有明显抑制作用,在体内药效学测定中证明了其对Pim的活性。
