Description：GDC0575 (ARRY-575) hydrochloride is a highly-selective and orally active Chk1 (IC50=1.2 nM) inhibitor. GDC0575 (ARRY-575) hydrochloride can be used for colitis-associated cancer (CAC) and colitis research.

In Vitro：GDC-0575 dihydrochloride is a selective and orally bioavailable CHK1 inhibitor, with an IC50 of 1.2 nM. GDC-0575 (100 nM) suppressses CHK1 activation induced by AraC by decreasing the level of Tyr15-phosphorylated CDK2[1]. GDC-0575 dihydrochloride (100 nM) has no effect on the viability of AML cells, but significantly reduces cell viability and induces apoptosis in combination with AraC. GDC-0575 plus AraC shows no effect on normal hematopoietic stem and progenitor cells (HSPCs)[1]. GDC-0575 shows cytotoxic activity against most of 20 melanoma cell lines tested, but several cell lines grown as tumour sphere (TS) are relatively insensitive[2].

In Vivo：GDC-0575 dihydrochloride (7.5 mg/kg, p.o.) in combination with AraC alomost completely eradicates leukemic burden in mice transplanted with U937-Luc cells, and shows more efficient activity than AraC alone. GDC-0575 dihydrochloride elevates the cytotoxicity of AraC in different primary AML models in vivo[1]. GDC-0575 dihydrochloride (25, 50 mg/kg, p.o.) dose-dependently inhibits the growth of tumor in D20 and C002 xenografts[2].

IC50 & Target：Chk1 1.2 nM (IC50)
