Methods of inhibiting phosphatidylinositol 3-kinase delta isoform (PI3Kδ) activity, and methods of treating diseases, such as disorders of immunity and inflammation, in which PI3Kδ plays a role in leukocyte function are disclosed. Preferably, the methods employ active agents that selectively inhibit PI3Kδ, while not significantly inhibiting activity of other PI3K isoforms. Compounds are provided that inhibit PI3Kδ activity, including compounds that selectively inhibit PI3Kδ activity. Methods of using PI3Kδ inhibitory compounds to inhibit cancer cell growth or proliferation are also provided. Accordingly, the invention provides methods of using PI3Kδ inhibitory compounds to inhibit PI3Kδ-mediated processes in vitro and in vivo.
本发明公开了抑制磷脂酰肌醇 3- 激酶δ异构体(PI3Kδ)活性的方法,以及治疗 PI3Kδ 在白细胞功能中发挥作用的疾病(如免疫和炎症紊乱)的方法。优选地,这些方法采用的活性剂可选择性地抑制 PI3Kδ,同时不会明显抑制其他 PI3K 同工酶的活性。提供了抑制 PI3Kδ 活性的化合物,包括选择性抑制 PI3Kδ 活性的化合物。还提供了使用 PI3Kδ 抑制性化合物抑制癌细胞生长或增殖的方法。因此,本发明提供了使用 PI3Kδ 抑制性化合物抑制体外和体内 PI3Kδ 介导过程的方法。
