Methods of inhibiting phosphatidylinositol 3-kinase delta isoform (PI3K&dgr;) activity, and methods of treating diseases, such as disorders of immunity and inflammation, in which PI3K&dgr; plays a role in leukocyte function are disclosed. Preferably, the methods employ active agents that selectively inhibit PI3K&dgr;, while not significantly inhibiting activity of other PI3K isoforms. Compounds are provided that inhibit PI3K&dgr; activity, including compounds that selectively inhibit PI3K&dgr; activity. Methods of using PI3K&dgr; inhibitory compounds to inhibit cancer cell growth or proliferation are also provided. Accordingly, the invention provides methods of using PI3K&dgr; inhibitory compounds to inhibit PI3K&dgr;-mediated processes in vitro and in vivo.
揭示了抑制
磷脂酰肌醇3-激酶δ异构体(
PI3Kδ)活性的方法,以及治疗疾病的方法,例如免疫和炎症紊乱,其中
PI3Kδ在白细胞功能中发挥作用。最好的方法是使用能够选择性抑制
PI3Kδ的活性的活性剂,同时不显著抑制其他
PI3K异构体的活性。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,该发明提供了使用
PI3Kδ抑制性化合物在体外和体内抑制
PI3Kδ介导的过程的方法。
