Diagnostic AML blasts from patients either at first diagnosis or at relapse are equally sensitive to MK-1775. Freshly isolated cells from patient AML#10 were purified by standard Ficoll-Hypaque density centrifugation. AML#10, HL-60, and HL-60/Ara-C cells were treated with MK-1775 for 48 h. Whole cell lysates were subjected to Western blotting and probed with anti-p-CDK1, -CDK1, -p-CDK2, -CDK2, -γH2AX, or -β-actin antibody.

GH activates STAT5 and ERK in breast cancer cells. T47D cells were pretreated for 2 hours with vehicle (dimethylsulfoxide) or inhibitors for EGFR (AG1478, 15 uM) or JAK2 (AZD1480, 1 uM), followed by treatment with GH+E2 for 30 minutes.

AZD1480 inhibits the JAK2/STAT3 pathway in vitro. HT29 cells were cultured in 24-well plates overnight and then treated with 1 uM AZD1480 for 2 h followed by 4 ng/ml, IL-6 for 2 h and the distribution of phosphorylated STAT3 was analyzed by immunofluorescence.

Histopathological assessment of tumor response to MK-1775 alone and in combination with gemcitabine in a patient-derived osteosarcoma mouse model. A. H&E-stained paraffin sections were prepared to assess microscopic features of cell death and differentiation representative micrographs of B. Ki67 shows high immunoreactivity in the control, MK-1775, and combination treatments compared to gemcitabine treatment. C. Cleaved-caspase 3 images show high immunoreactivity in the MK-1775 and combination treatments compared to vehicle and gemcitabine treatment. D. Slides stained for γH2AX show high immunoreactivity in gemcitabine, MK-1775, and combination treatments compared to controls. E. Slides stained for Cyclin A show higher immunoreactivity in gemcitabine but not in control, MK-1775 alone or in combination treatments.

MK-1775 inhibits Wee1 kinase in an ATP-competitive manner. Compared to Wee1, MK-1775 displays 2- to 3-fold less potency against Yes with IC50 of 14 nM, 10-fold less potency against seven other kinases with >80% inhibition at 1 μM, and >100-fold selectivity over human Myt 1, another kinase that inhibits cyclin-dependent kinase 1 (CDC2) by phosphorylation at an alternative site (Thr14). By abrogating the DNA damage checkpoint via blockade of Wee1 activity in WiDr cells bearing mutated p53, MK-1775 treatment inhibits the basal phosphorylation of CDC2 at Tyr15 (CDC2Y15) with EC50 of 49 nM, and suppresses gemcitabine-, carboplatin- or cisplatin-induced phosphorylation of CDC2 and cell cycle arrest in a dose-dependent manner, with EC50 of 82 nM and 81 nM, 180 nM and 163 nM, as well as 159 nM and 160 nM, respectively. MK-1775 treatment alone at 30-100 nM has no significant antiproliferative effect in WiDr and H1299 cells, whereas MK-1775 at 300 nM, sufficient to inhibit Wee1 by >80%, displays moderate but significant antiproliferative effects by 34.1% in WiDr cells and 28.4% in H1299 cells.

| 体内試験 | MK-1775 treatment alone at ~20 mg/kg displays minimal antitumor effects against WiDr xenografts in rats with T/C of 69% at day 3. Antitumor efficacy by MK-1775 alone in the nude rat HeLa-luc and TOV21G-shp53 xenograft models is also moderate. [1] |

In vitro kinase assays: Recombinant human Wee1 is used. Kinase reaction is conducted with 10 μM ATP, 1.0 μCi of [γ-33P]ATP, and 2.5 μg of poly(Lys, Tyr) as a substrate in the presence of increasing concentrations of MK-1775 at 30°C for 30 minutes. Radioactivity incorporated into the substrate is trapped on MultiScreen-PH plates and is counted on a liquid scintillation counter. |

質問1：
How to prepare MK1775 methylcellulose solution? and how to prepare methylcellulose itself? Once make the MK1775 methylcellulose solution, how should i keep it?
-
回答：
MK1775 in 0.5% methylcellulose is a suspension or emulsion, and it is ok to treat mice orally. It is recommended to dissolve methylcellulose in saline. It will take some time to dissolve methylcellulose, and you can vortex it for a while. The MK1775 methylcellulose solution can be stored at 4°C for a week.
