cancers. As such, the development of PI3K inhibitors from novel compound classes should lead to differential pharmacological and pharmacokinetic profiles and allow exploration in various indications, combinations, and dosing regimens. A screening effort aimed at the identification of PI3Kγ inhibitors for the treatment of inflammatory diseases led to the discovery of the novel 2,3‐dihydroimidazo[1,2‐c]quinazoline
磷酸肌醇3激酶(PI3K)途径在许多疾病状态中都被异常激活,包括肿瘤细胞,无论是通过生长因子受体酪氨酸激酶还是通过关键途径成分的基因突变和扩增。多种PI3K亚型在癌症中起着不同的作用。因此,从新型化合物类别开发PI3K抑制剂应导致不同的药理和药代动力学特征,并允许探索各种适应症,组合和给药方案。旨在鉴定用于治疗炎性疾病的PI3Kγ抑制剂的筛选工作导致发现了新型2,3-二氢咪唑[1,2- c喹唑啉类的PI3K抑制剂。随后针对癌症治疗的前导优化程序着重于抑制PI3Kα和PI3Kβ。在此,描述了此类的初始结构-活性关系发现以及优化方法,该方法导致将copanlisib(BAY 80-6946)鉴定为治疗实体瘤和血液肿瘤的临床候选药物。
