Activation of the phosphoinositide 3-kinase (PI3K) pathway is a key signaling event in cancer, inflammation, and other proliferative diseases. PI3K inhibitors are already approved for some specific clinical indications, but their systemic on-target toxicity limits their larger use. In particular, whereas toxicity is tolerable in acute treatment of life-threatening diseases, this is less acceptable
磷酸肌醇 3-激酶 (PI3K) 通路的激活是癌症、炎症和其他增殖性疾病中的关键信号传导事件。PI3K 抑制剂已经被批准用于一些特定的临床适应症,但它们的全身性靶向毒性限制了它们的更大用途。特别是,虽然毒性在危及生命的疾病的急性治疗中是可以容忍的,但在慢性疾病中则不太可接受。过去,克服这一缺点的策略是阻断主要在白细胞中表达的选定同种型,但 PI3K 家族成员中的冗余对这种方法的有效性提出了挑战。另一方面,减少对选定靶细胞的暴露是一种迄今为止尚未开发的规避全身毒性的替代方法。在这份手稿中,
