This invention is in the area of tricyclic lactam compounds, compositions and methods of protecting healthy cells, and in particular hematopoietic stem and progenitor cells (HSPC) as well as renal cells, from damage associated with DNA damaging chemotherapeutic agents. In one aspect, protection of healthy cells is disclosed using compounds that act as cyclin-dependent kinase 4/6 (CDK 4/6) inhibitors when administered to subjects undergoing DNA damaging chemotherapeutic regimens for the treatment of proliferative disorders.
这项发明涉及
三环内酰胺化合物领域,以及保护健康细胞的方法和组合物,特别是造血干细胞和祖细胞(HSPC)以及肾脏细胞,免受与DNA损伤化疗药物相关的损害。在一个方面,揭示了使用作为细胞周期依赖性激酶4/6(CDK 4/6)
抑制剂的化合物来保护健康细胞,当这些化合物被用于接受DNA损伤化疗方案治疗增殖性疾病的患者时。
