Biological Activity

Description

Adavosertib (MK-1775, AZD1775) is a potent and selective Wee1 inhibitor with IC50 of 5.2 nM in a cell-free assay; hinders G2 DNA damage checkpoint. Phase 2.

Features

The first reported Wee1 inhibitor.

Targets

Wee1 ^[1]
(Cell-free assay)

5.2 nM

In vitro
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. ^[1]
Kinase Assay	In vitro kinase assays
Kinase Assay	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.
Cell Research	Cell lines	WiDr, NCI-H1299, TOV21G, and HeLa
	Concentrations	Dissolved in DMSO, final concentrations ~10 μM
	Incubation Time	24 hours
	Method	Cells are treated with or without gemcitabine for 24 hours, then with MK-1775 for an additional 24 hours. Cell viability is determined with a WST-8 kit using SpectraMax. Cellular caspase-3/7 activities are determined with a Caspase-3/7 Glo kit.

In Vivo
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.
