AZD8186

The Uses of AZD8186

AZD 8186 is a potent and selective inhibitor of PI3Kβ and PI3Kδ for the treatment of PTEN-deficient cancers.

Biological Activity

the pi3k-akt signaling pathway plays a critical role in cell growth, proliferation, motility, and survival. in human cancer, this pathway is activated by several mechanisms, including somatic mutations, deletions, and amplifications. class i pi3ks are further divided into class ia enzymes (pi3kα, pi3kβ, and pi3kδ) and class ib enzymes (pi3kγ). azd8186 is a potent and selective inhibitor of pi3kβ and pi3kδ.

in vitro

azd8186 gave potent inhibition of p-akt in cells sensitive to pi3kβ inhibition and in cells sensitive to pi3kδ inhibition but not to cells sensitive to pi3kα inhibition. the overall kinase selectivity of azd8186 was evaluated in several panels of recombinant protein and lipid kinase assays. 13 did not show significant activity against a panel of 59 protein kinases tested at 1 μm [1].

in vivo

the antitumor activity of azd8186 was evaluated in the pten deficient pc3 prostate tumor xenograft model in nude mice, either at 100 mg/kg b.i.d. without abt coadministration, or at 60, 30, and 10 mg/mg b.i.d. with abt coadministration. higher inhibition was seen in the 60 and 30 mg/kg groups with abt coadministration than in the 100 mg/kg group without abt coadministration [1].
