Abstract

B cells express 4 phosphatidylinositol 3-kinase (PI3K) isoforms and have a dependence on p110δ for survival. The design of isoform-selective inhibitors is possible, and pharmacologic inhibition of p110δ is toxic to neoplastic chronic lymphocytic leukemia (CLL) cells for both cell-intrinsic and cell-extrinsic reasons. Idelalisib is a first-in-class p110δ inhibitor that exhibits efficacy for the treatment of relapsed CLL irrespective of adverse prognostic features. Duvelisib is a p110γ/δ inhibitor with a similar efficacy and safety profile to idelalisib. Recent data indicate that umbralisib, a p110δ/CK-1ε dual inhibitor, is safe and effective when administered to patients with CLL.

摘要

B 细胞表达 4 种磷脂酰肌醇 3-激酶(PI3K)同工型,并且依赖于 p110δ 来维持生存。同工型选择性抑制剂的设计是可行的,并且 p110δ 的药理学抑制对肿瘤性慢性淋巴细胞白血病(CLL)细胞具有内在和外在的毒性。Idelalisib 是一种首创的 p110δ 抑制剂,无论不良预后特征如何,对复发性 CLL 的治疗均有效。Duvelisib 是一种 p110γ/δ 抑制剂,其疗效和安全性与 idelalisib 相似。最近的数据表明,当给予 CLL 患者时,p110δ/CK-1ε 双重抑制剂 umbralisib 是安全有效的。
