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 with compounds of formula (1) are disclosed. Preferably, the methods employ active agents that selectively inhibit PI3Kδ, while not significantly inhibiting activity of other PI3K isoforms. Compounds of formula (1) 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. Wherein R1-R3, X, Y and A are defined herein.
本发明公开了抑制磷脂酰肌醇3-激酶δ亚型(PI3Kδ)活性的方法,以及使用式(1)化合物治疗疾病的方法,例如免疫和炎症障碍,其中PI3Kδ在白细胞功能中发挥作用。优选地,该方法采用有选择性地抑制PI3Kδ的活性的活性剂,同时不显著抑制其他PI3K亚型的活性。提供了抑制PI3Kδ活性的式(1)化合物,包括有选择性地抑制PI3Kδ活性的化合物。还提供了使用PI3Kδ抑制剂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抑制剂化合物在体外和体内抑制PI3Kδ介导的过程的方法。其中R1-R3,X,Y和A在此定义。
