PF-04691502是高效选择性PI3K/mTOR (FRAP)双重抑制剂，抑制Akt T308 (IC50 = 7.5 nM)和Akt S473 (IC50 = 3.8 nM)的磷酸化[1]。
PI3Ks是参与细胞功能的酶家族，如细胞生长、增殖、分化、运动、存活和胞内运输，从而也参与癌症。PI3Ks的功能大多与1类PI3K 在PI3K/AKT/mTOR通路中激活蛋白激酶B (PKB，亦称Akt)相关，此信号通路与细胞静止、增殖、癌症和永生直接相关。此通路中有诸多有价值的抗癌药物治疗靶点。p110δ和p110γ亚型调节免疫应答的不同方面[2]。
PF-04691502是一种有潜能的药物，由荧光偏振激酶试验、细胞、小鼠和其他动物试验得出PF-04691502的功能为抑制PI3K/AKT/mTOR通路中的1类PI3K和mTOR，此外，由此抑制作用，PF-04691502能抑制肿瘤[3, 4]。PF-04691502短时间处理能显著抑制PI3K，而对mTOR的抑制作用需要持续24-48小时。PF-04691502诱导细胞周期G1期停滞，伴随p27 Kip1的上调和Rb的下调[5]。PF-04691502的抗肿瘤活性已在U87 (PTEN null)、SKOV3 (PIK3CA 突变)、耐gefitinib和erlotinib的非小细胞肺癌异种移植物中观察到。PF-04691502在第七天抑制肿瘤生长达到72%。FDG-PET成像表明PF-04691502显著降低葡萄糖代谢。PF-04691502处理也能显著抑制PI3K/mTOR通路活性的组织标志物p-AKT (S473)和p-RPS6 (S240/244)[6]。
