| In vitro |
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.

| In vivo | 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] |

Frequently Asked Questions
Question 1:
How to prepare MK1775 methylcellulose solution? and how to prepare methylcellulose itself? Once make the MK1775 methylcellulose solution, how should i keep it?
Answer:
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.
