This invention is in the area of improved compounds for and methods of treating selected RB-positive cancers and other Rb-positive abnormal cellular proliferative disorders while minimizing the deleterious effects on healthy cells, for example healthy Hematopoietic Stem Cells and Progenitor Cells (HSPCs), associated with current treatment modalities. In one aspect, improved treatment of select RB-positive cancers is disclosed using specific compounds disclosed herein. In certain embodiments, the compounds described herein act as highly selective and, in certain embodiments, short, transiently-acting cyclin-dependent kinase 4/6 (CDK 4/6) inhibitors when administered to subjects.
本发明涉及用于治疗选定的 RB 阳性癌症和其它 Rb 阳性异常细胞增殖性疾病的改良化合物和方法,同时最大限度地减少与当前治疗方法相关的对健康细胞(例如健康的造血干细胞和祖细胞(HSPC))的有害影响。在一个方面,本文公开了使用本文公开的特定化合物改善对特定 RB 阳性癌症的治疗。在某些实施方案中,本文所述的化合物在给受试者用药时可作为高选择性、在某些实施方案中为短效、瞬时作用的细胞周期蛋白依赖性激酶4/6(CDK 4/6)抑制剂。
