Poids moléculaire : 591,47 Le BX795 est un inhibiteur puissant et spécifique de PDK1 avec une CI50 de 6 nM, 140 et 1600 fois plus sélectif pour PDK1 que PKA et PKC, respectivement. Pendant ce temps, par rapport à GSK3β, une sélectivité plus de 100 fois observée pour PDK1.
Le BX-795 bloque efficacement l'activité de PDK1 dans les cellules PC-3, comme le montre leur capacité à bloquer la phosphorylation de S6K1, Akt, PKCδ et GSK3β. Le BX-795 inhibe puissamment la croissance des cellules tumorales sur le plastique avec une CI50 de 1,6, 1,4 et 1,9 M pour les cellules MDA-468, HCT-116 et MiaPaca, respectivement. Dans la gélose molle, le BX-795 affiche une inhibition de croissance plus élevée avec une CI50 de 0,72 et 0,25 M pour les cellules MDA-468 et PC-3, respectivement. De plus, le BX-795, en tant qu'inhibiteur de TBK1/IKKɛ, bloque l'activation d'IRF3 et la production d'IFN-β médiée par TBK1 et IKKε. Dans les réponses physiologiques plaquettaires, le BX795 produit un effet inhibiteur sur l'agrégation induite par le 2-MeSADP ou induite par le collagène, la sécrétion d'ATP et la génération de thromboxane.

Kinase assays	PDK1 is assayed in a direct kinase assay and a coupled assay format measuring PDK1- and PtdIns-3,4-P2-mediated activation of AKT2. For the coupled assay, the final assay mixture (60 μL) contained: 15 mM MOPS, pH 7.2, 1 mg/mL bovine serum albumin, 18 mM β-glycerol phosphate, 0.7 mM dithiothreitol, 3 mM EGTA, 10 mM MgOAc, 7.5 μM ATP, 0.2 μCi of [γ-33P]ATP, 7.5 μM biotinylated peptide substrate (biotin-ARRRDGGGAQPFRPRAATF), 0.5 μL of PtdIns-3,4-P2-containing phospholipid vesicles, 60 pg of purified recombinant human PDK1, and 172 ng of purified recombinant human AKT2. After incubation for 2 h at room temperature, the biotin-labeled peptide is captured from 10 μl of the assay mixture on streptavidin-coated SPA beads, and product formation is measured by scintillation proximity in a Wallac MicroBeta counter. The product formed is proportional to the time of incubation and to the amount of PDK1 and inactive AKT2 added. PDK1 is added at suboptimal levels so that the assay could sensitively detect inhibitors of AKT2 activation as well as direct inhibitors of PDK1 or AKT2. To measure PDK1 activity directly, the final assay mixture (60 μL) contained 50 mM Tris-HCl, pH 7.5, 0.1 mM EGTA, 0.1 mM EDTA, 0.1% β-mercaptoethanol, 1 mg/mL bovine serum albumin, 10 mM MgOAc, 10 μM ATP, 0.2 μCi of [γ-33P]ATP, 7.5 μM substrate peptide (H2N-ARRRGVTTKTFCGT), and 60 ng of purified recombinant human PDK1. After 4 h at room temperature, we add 25 mM EDTA and spotted a portion of the reaction mixture on Whatman P81 phosphocellulose paper. The filter paper is washed three times with 0.75% phosphoric acid and once with acetone. After drying, the filter-bound labeled peptide is quantified using a Fuji phosphorimager.

Dosage cellulaire : [1]

Cell lines	MDA-468, PC-3, HCT-116 and MiaPaca cells
Concentrations	~10 μM
Incubation Time	72 hours
Method	Cells seeded at a low density (1,500–3,000 cells/well, 0.1 mL/well, 96-well plates) are incubated overnight. Compound treatments are made by adding 10 μL/well of the compound in 1% dimethyl sulfoxide and growth medium (final concentration of dimethyl sulfoxide, 0.1%), followed by brief shaking. Treated cells are incubated for 72 hours, and viability is measured by the addition of 10 μL of the metabolic dye WST-1. The WST-1 signal is read in a plate reader at 450 nm, and a no cell, or zero time cell, background is subtracted to calculate the net signal. Results are reported as the average ± S.E. of two or more replicates.

Animal A (mg/kg) = Animal B (mg/kg) multiplied by	Animal B Km

Par exemple, pour modifier la dose de resvératrol utilisée pour une souris (22,4 mg/kg) à une dose basée sur la BSA pour un rat, multiplier 22,4 mg/kg par le facteur Km pour une souris puis diviser par le facteur Km pour un rat. Ce calcul donne une dose équivalente chez le rat pour le resvératrol de 11,2 mg/kg.

Rat dose (mg/kg) = mouse dose (22.4 mg/kg) ×	mouse Km(3)	= 11.2 mg/kg
