Biological Activity:
AZD8055 is a highly potent, selective and ATP-competitive mTOR inhibitor (IC50
= 0.8 nM). It has >1,000-fold selectivity against all PI3K isoforms
(α, β, γ, δ) and other members of the PI3K-like kinase family (ATM and
DNA-PK). It has no significant activity against a panel of 260 kinases
at concentrations up to 10 μM. AZD8055 inhibits the phosphorylation of
mTORC1 downstream targets (p70S6K and 4E-BP1) as well as phosphorylation
of the mTORC2 downstream proteins (e.g., Akt). 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 of U87MG, A549 and
H838 cells with IC50 of 53, 50, and 20 nM, respectively. It
also induces autophagy and increases 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. It also 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 was previously evaluated
in a phase I clinical study in patients with advanced tumors.?
How to Use:
In vitro: AZD8055 was used at 2.5 μM concentration in vitro and cellular assays.
In vivo: AZD8055 was orally dosed to mice at 2.5-20 mg/kg once or twice per day to inhibit tumor growth.
