AZD8055 shows low activity (∼1,000-fold) against all PI3K isoforms (α, β, γ, δ) and other members of the PI3K-like kinase family (ATM and DNA-PK). AZD8055 inhibits the phosphorylation of mTORC1 (p70S6K and 4E-BP1) as well as phosphorylation of the mTORC2 (Akt) and downstream proteins. The rapamycin-resistant T37/46 phosphorylation sites on 4E-BP1 can be fully inhibited by AZD8055, resulting in significant inhibition of cap-dependent translation. AZD8055 potently inhibits proliferation in U87MG, A549 and H838 cells with IC50 of 53, 50 and 20 nM, respectively. AZD8055 also induces autophagy and increased LC3-II levels in H838 and A549 cells. AZD8055 decreases AML blast cell proliferation and cell cycle progression, reduces the clonogenic growth of leukemic progenitors and induces caspase-dependent apoptosis in leukemic cells but not in normal immature CD34+ cells. AZD8055 indicates inhibitory against the pediatric preclinical testing program (PPTP) cell lines with IC50 of 24.7 nM and induces significant differences in EFS distribution.

AZD8055 inhibits the pS6 and pAkt in U87MG and A549 xenografts at 2.5/10 mg/kg, which leads to tumor growth inhibition. AZD8055 shows significant antitumor activity in many xenografts, including U87MG, BT474c, A549, Calu-3, LoVo, SW620, PC3 and MES-SA at a dose of 10/20 mg/kg. AZD8055 induces ~40% reduction in tumour volume, accompanied by ablation of phosphorylation of Akt, S6K and SGK protein kinases. Administration of AZD8055 (5mg/kg, Bid) and SAHA (100 mg/kg/d) results in complete tumor growth inhibition in PTEN+/−LKB1+/hypo xenografts without side effects on mice by inhibition of mTORC1 and mTORC2 signaling.
