MK-1775 Chemische Eigenschaften,Einsatz,Produktion Methoden

Beschreibung
MK-1775 is a small molecule inhibitor of the tyrosine kinase WEE1 with potential antineoplastic sensitizing activity. MK-1775 selectively targets and inhibits WEE1, a tyrosine kinase that phosphorylates cyclin-dependent kinase 1 (CDK1, CDC2) to inactivate the CDC2/cyclin B complex. Inhibition of WEE1 activity prevents the phosphorylation of CDC2 and impairs the G2 DNA damage checkpoint. This may lead to apoptosis upon treatment with DNA damaging chemotherapeutic agents. MK-1775 is a type of biological therapy. It is a cancer growth blocker. It stops signals that cancer cells use to divide and grow. MK-1775 has been used in trials studying the treatment of LYMPHOMA, Neoplasms, Ovarian Cancer, Tongue Carcinoma, and Adult Glioblastoma, among others.
Verwenden
MK 1775 is used in biological studies for the abrogation of G2/M checkpoint through WEE1 inhibition in combination with chemotherapy as a promising therapeutic approach for mesothelioma.
Definition
ChEBI: 1-[6-(2-hydroxypropan-2-yl)-2-pyridinyl]-6-[4-(4-methyl-1-piperazinyl)anilino]-2-prop-2-enyl-3-pyrazolo[3,4-d]pyrimidinone is a member of piperazines.
in vitro
mk-1775 dose-dependently inhibited phosphorylation of cdc2 at tyr15 and abrogated the g2dna damage checkpoint. mk-1775 inhibited wee1 kinase in an atp-competitive manner with an ic50 value of 5.2 nmol/l in the in vitro kinase assays. compared to wee1, mk-1775 displayed 2- to 3-fold less potency against yes with the ic50value 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 inhibited 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 inhibited the basal phosphorylation of cdc2 at tyr15 (cdc2y15) with an ec50 of 49 nm, and dose-dependently suppressed gemcitabine-, carboplatin- or cisplatin-induced phosphorylation of cdc2 and cell cycle arrest, with the ec50 of 82 nm and 81 nm, 180 nm and 163 nm, as well as 159 nm and 160 nm, respectively. in widr and h1299 cells, mk-1775 treatment (30-100 nm)showed no significant antiproliferative effects, whereas mk-1775 at 300 nm was sufficient to inhibit wee1 by >80%, displayed moderate but significant antiproliferative effects by 34.1% in widr cells and 28.4% in h1299 cells [1].
