AZD-8055

AZD8055 (1009298-09-2) is a potent and highly selective inhibitor of mammalian target of rapamycin kinase (mTOR) kinase (IC50 = 0.8 nM).1,2 mTOR acts as a nutrient/energy/redox sensor and a controller of protein synthesis – as such it is a very important target for cancer research. It has been investigated as a potential chemotherapeutic for various cancers.3-7

A potent, selective, and orally bioavailable ATP-competitive mTOR kinase inhibitor with an IC50 of 0.8 nM. It inhibits the phosphorylation of mTORC1 substrates p70S6K and 4E-BP1 as well as phosphoryla tion of the mTORC2 substrate AKT and downstream proteins. The rapamycin-resistant T37/46 phosphorylation sites on 4E-BP1 were fully inhibited by AZD8055, resulting in significant inhibition of cap-dep endent translation. In vitro, AZD8055 potently inhibits proliferation and induces autophagy in H838 and A549 cells. In vivo, AZD8055 induces a dose-dependent pharmacodynamic effect on phosphorylated S 6 and phosphorylated AKT at plasma concentrations leading to tumor growth inhibition.

A novel ATP-competitive inhibitor of mTOR with an IC50 of 0.8 nM.

ChEBI: AZD-8055 is a pyridopyrimidine that is pyrido[2,3-d]pyrimidine which is substituted at positions 2 and 4 by (3S)-3-methylmorpholin-4-yl groups and at position 5 by a 3-(hydroxymethyl)-4-methoxyphenyl group. It is an mTOR complex 1/2 (mTORC1/2) dual inhibitor [mTOR = mammalian target of rapamycin]. It has a role as a mTOR inhibitor, an apoptosis inducer and an antineoplastic agent. It is a member of benzyl alcohols, a tertiary amino compound, a pyridopyrimidine and a member of morpholines.
