LY2606368 HCl is a selective ATP competitive inhibitor of checkpoint kinase 1 (IC50: 1.5nM in SW1990 cells).

Prexasertib dihydrochloride (LY2606368) is an ATP-competitive CHK1 inhibitor (Ki: 0.9 nmol/L). in the cell-free assay, its IC50 values are 8 nM and 9 nM for CHK2 and RSK, respectively.

Prexasertib is a potent and selective Chk1/Chk2 inhibitor. Prexasertib increases the effectiveness of conventional therapy in B-/T- cell progenitor acute lymphoblastic leukemia. LY2606368 causes replication catastrophe and antitumor effects through CHK1-d

Prexasertib dimesylate (LY2606368 dimesylate) is a highly selective ATP-competitive second-generation inhibitor of checkpoint kinase 1 (CHK1). With a K i of 0.9 nM and an IC 50 of <1 nM, Prexasertib dimesylate effectively inhibits CHK2 (IC 50 = 8 nM) and RSK1 (IC 50 = 9 nM). Its mechanism of action involves inducing double-stranded DNA breakage and replication catastrophe, ultimately leading to apoptosis. Moreover, Prexasertib dimesylate demonstrates potent anti-tumor activity.

Prexasertib is an effective and selective Chk1/Chk2 inhibitor. Prexasertib causes Replication Catastrophe and Antitumor Effects through CHK1-Dependent Mechanisms.

Prexasertib (LY2606368) is an inhibitor of checkpoint kinase 1 (chk1) with potential antineoplastic activity.
