In vitro
AZD8186 potently inhibits p-Akt in MDA-MB-468 cells sensitive to PI3Kβ inhibition and Jeko B cells sensitive to PI3Kδ inhibition with IC50 of 3 nM and 4 nM, respectively. [1] This compound shows preferred growth inhibition activity in most PTEN deficient cell lines with GI50 of <1 μM. [2]
Kinase Assay
PI3Kα, PI3Kβ, PI3Kγ and PI3Kδ enzyme assays
The inhibition of PI3Kα, PI3Kβ, PI3Kγ and PI3Kδ human recombinant PI3K isoforms is evaluated using a Kinase-Glo Plus Assay Kit. 12 point half-log concentration-response curves with a top concentration of 100 μM are constructed by dispensing DMSO solubilised compounds into white 384-well medium-binding microplates using an Echo 555. 3 μL of the appropriate PI3K in Tris buffer (50 mM Tris pH7.4, 0.05% CHAPS, 2.1 mM DTT, and 10 mM MgCl2) is added. The plate is covered and allowed to pre-incubate with compound for 20 minutes prior to addition of 3 μL of substrate solution containing PIP2 and ATP. The enzyme reaction is stopped after 80 minutes by the addition of Kinase Glo detection solution. Plates are covered and incubated for 30 minutes at room temperature before the luminescence signal is read using a PHERAstar plate reader. The final concentrations of DMSO, ATP and PIP2 in the assay are 2%, 8 μM, and 80 μM respectively. The final concentrations of PI3Kα, PI3Kβ, PI3Kγ and PI3Kδ are respectively 20 nM, 20 nM, 45 nM and 30 nM. For PI3Kα, PI3Kβ and PI3Kδ the concentration of active enzyme is determined as outlined in the enzyme assay tight binding limit determination section. For PI3Kγ the concentration of enzyme is determined by Bradford assay. IC50 values are calculated using Genedata Screener.
In vivo
In nude mice bearing PTEN-deficient PC3 prostate tumor xenografts, AZD8186 (100 mg/kg, p.o.) strongly inhibits Akt phosphorylation levels, and causes significant tumor growth inhibition. When used in combination with ABT, this compound (60 mg/kg, p.o.) results in complete inhibition of tumor growth. [1] In the mouse PTEN-null TNBC models HCC70 and MDA-MB-468, and the prostate models HID28, this chemical (50 mg/kg, p.o.) also inhibits the growth of tumors. [2] Combination therapy using this compound with androgen deprivation results in long-lasting tumor regression, which persisted after treatment cessation. [3]
