组织蛋白酶 C (Cat C) 通过影响中性粒细胞丝氨酸蛋白酶 (NSP) 的激活参与炎症和免疫调节。因此,组织蛋白酶 C 是治疗 NSP 相关炎症性疾病的一个有吸引力的靶点。在此,从命中发现、结构优化和先导化合物发现三个方面描述了第一个强效“非肽基非共价组织蛋白酶C抑制剂”的完整发现过程。从hit 14开始,全面开展了基于结构的优化和构效关系研究,发现先导化合物54在体内和体外均是一种有效的类药组织蛋白酶C抑制剂。此外,化合物54 (与组织蛋白酶 C Enz IC 50 = 57.4 nM)在慢性阻塞性肺病动物模型中表现出有效的抗炎活性。这些结果证实了非肽基和非共价衍生物可以用作有效的组织蛋白酶C抑制剂,并鼓励我们在此发现的基础上继续进一步的药物发现。

This invention directed to methods for treating select RB-positive cancers and other Rb- positive abnormal cellular proliferative disorders using CDK4/6 inhibitors in specific dosing and combination or alternation regimes. In one aspect, treatments of select RB-positive cancers are disclosed using specific CDK4/6 inhibitors in combination or alternation with another chemotherapeutic, for example, an additional kinase inhibitor, PD-1 inhibitor, or BCL-2 inhibitor, or combination thereof.
synthetic strategy is the development of an unprecedented palladium‐catalyzedcoupling reaction of ammonia with chloropyridinesdeactivated by the presence of an alkylamino substituent. The coupling reaction was accomplished with very low catalyst loadings under remarkably mild reaction conditions, making the system particularly suitable for both academic and industrial applications. The utility of this methodology
Compounds of formulae I, II or III, and pharmaceutically acceptable salts thereof, are useful as CDK inhibitors.
式I、II或III的化合物及其药用盐可用作CDK抑制剂。

This invention is in the area of improved compounds, compositions and methods of transiently 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, improved protection of healthy cells is disclosed using disclosed compounds that act as highly selective and short, transiently-acting cyclin-dependent kinase 4/6 (CDK 4/6) inhibitors when administered to subjects undergoing DNA damaging chemotherapeutic regimens for the treatment of proliferative disorders.
