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.
