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[1][2].
Prexasertib dimesylate (LY2606368 dimesylate) inhibits MELK (IC50=38 nM), SIK (IC50=42 nM), BRSK2 (IC50=48 nM), ARK5 (IC50=64 nM). Prexasertib dimesylate requires CDC25A and CDK2 to cause DNA damage[1]. Prexasertib dimesylate (33, 100 nM; for 7 hours) results in DNA damage during S-phase in HeLa cells[1]. Prexasertib dimesylate (8-250 nM; pre-treated for 15 minutes) inhibits CHK1 autophosphorylation (S296) and CHK2 autophosphorylation (S516) in HT-29 cells[1]. Prexasertib dimesylate (4 nM; 24 hours) results in a large shift in cell-cycle populations from G1 and G2-M to S-phase with an accompanied induction of H2AX phosphorylation in U-2 OS cells[1]. Prexasertib dimesylate (33 nM; for 12 hours) causes chromosomal fragmentation in HeLa cells. Prexasertib dimesylate (100 nM; 0.5 to 9 hours) induces replication stress and depletes the pool of available RPA2 for binding to DNA[1]. Cell Cycle Analysis[1] Cell Line: HeLa cells
Prexasertib dimesylate (LY2606368 dimesylate; 1-10 mg/kg; SC; twice daily for 3 days, rest 4 days; for three cycles) causes growth inhibition in tumor xenografts[1]. Prexasertib dimesylate (15 mg/kg; SC) causes CHK1 inhibition in the blood and the phosphorylation of both H2AX (S139) and RPA2 (S4/S8)[1]. Animal Model: Female CD-1 nu-/nu- mice (26-28 g) with Calu-6 cells[1]

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |
