In Vitro
In vitro PHA-793887 has low activity against CDK1, CDK4, CDK9 and GSK3β with IC50 of 60 nM, 62 nM, 138 nM and 79 nM, respectively. PHA-793887 inhibits cell proliferation of many tumor cell lines, including A2780, HCT-116, COLO-205, C-433, DU-145, A375, PC3, MCF-7, and BX-PC3, with IC50 of 88 nM–3.4 μM. PHA-793887 (1 μM) shows a decrease in the S phase, a subsequent increase of the G1 phase and a slight accumulation of G2/M phase in A2780 cells. PHA-793887 (3 μM) significantly increases G2/M phase and reduces DNA synthsis. [1] PHA-793887 is cytotoxic for leukemic cell lines, including K562, KU812, KCL22, and TOM1, with IC50 of 0.3–7 μM, but it is not cytotoxic for normal unstimulated peripheral blood mononuclear cells or CD34+ hematopoietic stem cells. In colony assays, PHA-793887 shows very high activity against leukemia cell lines with IC50 less than 0.1 μM. PHA-793887 induces cell-cycle arrest, inhibits Rb and nucleophosmin phosphorylation, and modulates cyclin E and cdc6 expression at 0.2−1 μM and induces apoptosis at 5 μM. [2]
Kinase Assay CDK Kinase Assay
The biochemical activity of compounds is determined by incubation with specific enzymes and substrates, followed by quantitation of the phosphorylated product. PHA-793887 (1.5 nM–10 μM) is incubated for 30−90 min at room temperature in the presence of ATP/33P-γ-ATP mix, substrate, and the specific enzyme (0.7−100 nM) in a final volume of 30 μL of kinase buffer, using 96 U bottom plates. After incubation, the reaction is stopped and the phosphorylated substrate is separated from nonincorporated radioactive ATP using SPA beads, Dowex resin, or Multiscreen phosphocellulose filter as follows: (1) For SPA Assays. The reaction is stopped by the addition of 100 μL of PBS + 32 mM EDTA + 0.1% Triton X-100 + 500 μM ATP, containing 1 mg of streptavidin-coated SPA beads. After 20 min of incubation for substrate capture, 100 μL of the reaction mixture is transferred into Optiplate 96-well plates containing 100 μL of 5 M CsCl, left to stand for 4 hours to allow stratification of beads to the top of the plate, and counted using TopCount to measure substrate-incorporated phosphate. (2) For Dowex Resin Assay. An amount of 150 μL of resin/formate, pH 3.00, is added to stop the reaction and capture unreacted 33P-γ-ATP, separating it from the phosphorylated substrate in solution. After 60 min of rest, 50 μL of supernatant is transferred to Optiplate 96-well plates. After the additon of 150 μL of Microscint 40, the radioactivity is counted in the TopCount. (3) For Multiscreen Assay. The reaction is stopped with the addition of 10 μL of EDTA (150 mM). An amount of 100 μL is transferred to a MultiScreen plate to allow substrate binding to phosphocellulose filter. Plates are then washed three times with 100 μL of H2PO4 (75 mM) filtered by a MultiScreen filtration system, and dried. After the additon of 100 μL of Microscint 0, radioactivity is counted in the TopCount. IC50 values are obtained by nonlinear regression analysis.

実験の流れ Cells are seeded into 96- or 384-wells plates at final concentration ranging from 1 × 104 to 3 × 104 per cm2. After 24 hours, cells are treated using serial dilution of PHA-793887. At 72 hours after the treatment, the amount of cells are evaluated using the CellTiter-Glo assay. IC50 values are calculated using a sygmoidal fitt
In Vivo
In Vivo PHA-793887 (10–30 mg/kg) shows good efficacy in the human ovarian A2780, colon HCT-116, and pancreatic BX-PC3 carcinoma xenograft models. [1] PHA-793887 (20 mg/kg) is effective in xenograft models of K562 and HL60 cells, primary leukemic disseminated model, and a high-burden disseminated ALL-2 model derived from a relapsed Philadelphia-positive acute lymphoid leukemia patient.
