AZD8055是一种高效选择性的、ATP竞争型的mTOR抑制剂，在MDA-MB-468细胞中IC50值为0.8 nM。AZD8055除了可以抑制mTORC1（p70S6K和4E-BP1）和mTORC2 (AKT) 以外，还完全抑制4E-BP1抗Rapamycin的T37/46磷酸化位点，明显地抑制cap-dependent转译作用，可有效地抑制U87MG, A549和H838等细胞增殖、诱导自体吞噬和导致LC3-II水平增加。在体外研究中，基于AZD8055作用于U87MG, BT474c, A549, Calu-3, LoVo, SW620, PC3和MES-SA移植瘤时，抑制pS6和pAKT，导致肿瘤生长受抑制，诱导肿瘤体积下降，表现出明显的抗癌活性。
