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 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
