AZD8055 is a new ATP-competitive mTOR inhibitor with an IC50 of 0.8 nmol/L and a Ki of 1.3 nmol/L[1]. mTOR is a serine/threonine kinase, and AZD8055 is a potent mTORC1/mTORC2 dual inhibitor[2]. AZD8055 significantly inhibits the phosphorylation of AktSer473 and induces apoptosis [3].
In vitro, AZD8055 (5 nmol/L) resulted in 70% to 80% inhibition of p70S6K in MCF-7 and HEK cells. AZD8055 also inhibited a variety of cancer cells (including U87MG, BT474c, A549, Calu-3, LoVo, SW620 , PC3 and MES-SA, etc.) show obvious anti-cancer activity[1]. AZD8055 (0.1 and 1uM) significantly inhibits the activity of mTORC1 and mTORC2, thereby inhibiting AktSer473 phosphorylation in human neuroblastoma cell lines, and also inhibits cell growth in vitro by inducing autophagy, apoptosis and cell cycle arrest [2]. The IC50 of AZD8055 against several laryngeal cancer cell lines are: UM-SCC-98 (~40μM), UM-SCC-12 (~23μM), and UM-SCC-11A (~8μM) [4].
In vivo, AZD8055 (5 mg/kg) was injected intraperitoneally every other day for xenograft model mice for eight times in total, which inhibited tumor growth and had no obvious adverse effects on the body weight of the mice[2]. Intraperitoneal injection of AZD8055 (10 mg/kg) into mice transiently increases plasma insulin levels 3-fold, induces insulin resistance in mice, and impairs mTOR signaling in insulin-responsive tissues. It also causes increased lipid oxidation and glucose Intolerance[5]. Oral treatment of PTEN+/−LKB1+/hypo mice with AZD8055 (20mg/kg) for 42 days induced a reduction of approximately 40% in tumor volume and simultaneously ablated the phosphorylation of AKT, S6K and SGK protein kinases[6].
