Description:

A potent, selective, reversible, ATP-competitive Chk2 inhibitor with IC50 of 0.2 uM; displays no effect on a range of other kinases including Chk1 (IC50>10 uM); inhibits histone H1 phosphorylation (IC50=0.24 uM) and attenuates mitochondrial ATP synthesis; exhibits antiproliferative activity in a number of leukemias in vivo.

Cat. No.	Product name	Field of application
DC41105	Prexasertib dimesylate	Prexasertib dimesylate (LY2606368 dimesylate) is a selective, ATP-competitive second-generation checkpoint kinase 1 (CHK1) inhibitor with a Ki of 0.9 nM and an IC50 of <1 nM. Prexasertib dimesylate inhibits CHK2 (IC50=8 nM) and RSK1 (IC50=9 nM). Prexasertib dimesylate causes double-stranded DNA breakage and replication catastrophe resulting in apoptosis. Prexasertib dimesylate shows potent anti-tumor activity.
DC41104	Prexasertib Mesylate Hydrate	Prexasertib Mesylate Hydrate (LY2606368 Mesylate Hydrate) is a selective, ATP-competitive second-generation checkpoint kinase 1 (CHK1) inhibitor with a Ki of 0.9 nM and an IC50 of <1 nM. Prexasertib Mesylate Hydrate inhibits CHK2 (IC50=8 nM) and RSK1 (IC50=9 nM). Prexasertib Mesylate Hydrate causes double-stranded DNA breakage and replication catastrophe resulting in apoptosis. Prexasertib Mesylate Hydrate shows potent anti-tumor activity.
DC40569	Chk1-IN-5	Chk1-IN-5 is a potent checkpoint kinase 1 (Chk1) inhibitor. Chk1-IN-5 inhibits Chk1 phosphorylation and inhibits tumor growth in colon cancer xenograft model.
DC11732	GNE-900	GNE-900 (GNE900) is a potent, selective, ATP-competitive, and orally bioavailable Chk1 inhibitor with IC50 of <1 nM.
DC9399	CCT241533 (hydrochloride)	CCT241533 Hcl is a potent serine/threonine checkpoint kinase (Chk2) inhibitor with IC50 of 3 nM; shows minimal cross-reactivity against a panel of kinases at 1 uM.
DC11713	NSC-109555 ditosylate	A potent, selective, reversible, ATP-competitive Chk2 inhibitor with IC50 of 0.2 uM.
DC11733	SAR-020106	A potent, selective, ATP-competitive Chk1 inhibitor with IC50 of 13.3 nM.
