产品详情
生物活性:
GDC-0575 (ARRY-575, RG7741) is a highly-selective oral small-molecule Chk1 inhibitor with an IC50 of 1.2?nM.

体内研究:
GDC-0575 is active at 25 mg/kg as a single agent, but the efficacy is improved at the higher drug dose. GDC-0575 effectively blocks tumor growth in the D20 and C002 xenografts, and the effect is maintained for at least 10 days after the final dose is administered.

体外研究:
GDC-0575 is significantly more potent in promoting DNA damage, replication stress and cell death than V158411, LY2603618, and MK-8776 in a panel of melanoma cell lines. GDC-0575 abrogates DNA damage-induced S and G2–M checkpoints, exacerbates DNA double-strand breaks and induces apoptosis in STS cells. GDC-0575 has a synergistic or additive effect together with gemcitabine. CHK1 inhibitor GDC-0575 in combination with AraC enhances the killing of primary acute myeloid leukemia cells ex vivo by inducing apoptosis.
