描述 | Chk1 (Checkpoint kinase 1), an important serine/threonine kinase, is responding to DNA damage and stall DNA replication. Chk1 plays a key role in maintaining the replication fork viability during exposure to DNA antimetabolites. Inhibition of Chk1 will lead to accumulation of double-strand DNA breaks and cell death in human tumor cell lines exposure to antimetabolite. GDC-0575 is a selective Chk1 inhibitor with IC50 value of 1.2 nM. GDC-0575 exhibited anti-proliferative effect on nine of ten soft-tissue sarcoma (STS) cell lines with IC50 values ranging in 0.025-5.9μM, with inhibition of the phosphorylation of Ser296 observed. GDC-0575 could synergy with gemcitabine. It abrogated DNA damage-induced S and G2–M checkpoints exacerbated DNA double-strand breaks and induced apoptosis in STS cells. Combined therapy of GDC-0575 (25mg/kg, orally) with gemcitabine twice a week for 3 weeks significantly reduced tumor growth increased progression-free survival of a P53mut UPS PDX model. GDC-0575 could enhance AraC-mediated killing of AML cells both in vitro and in vivo with abrogation of any potential chemoresistance mechanisms involving DNA repair. |
作用机制 | GDC-0575 is an ATP-competitive CHK1 inhibitor. |
