生物活性
PF-4708671是一种细胞渗透性p70 ribosomal S6 kinase(S6K1亚型)抑制剂，在无细胞试验中Ki/IC50为20 nM/160 nM，作用于S6K1比作用于S6K2选择性高400倍，作用于S6K1比作用于MSK1和RSK1/2选择性分别高4和20倍以上，是第一个报道的S6K1特异性抑制剂。

体外研究
PF-4708671是一种哌嗪基嘧啶类似物，是第一个S6K1特异性抑制剂。PF-4708671不显著抑制紧密相关的S6K2亚型或一组其他AGC激酶 (Akt1, Akt2, PKA, PKCα, PKCϵ, PRK2, ROCK2, RSK1, RSK2 或SGK1)的活性。PF-4708671抑制S6K1介导的响应IGF-1（胰岛素样生长因子1）的S6蛋白的磷酸化，对PMA-诱导的底物磷酸化没有作用效果，底物与RSK (p90核糖体S6激酶)和MSK（丝分裂原和应激活化蛋白激酶）激酶高度相关。PF-4708671诱导S6K1的T型环和疏水性基序磷酸化，这种作用依赖于mTORC1 (mTOR复合体1)。PF-4708671不影响mTORC1的活性。
体内研究
The tumor growth rate in mice treated with the combination of OSI-906+PF-4708671 is significantly slower than that of OSI-906 alone (P=0.0189) or PF4708671 alone (P=0.0165) treated mice. The average tumor volume in the OSI-906+PF-4708671-treated mice is approximately 50% of that in mice treated with OSI-906 (P=0.0056) or PF-4708671 alone (P<0.001) at the end of a 15-day treatment.
