生物活性

Prexasertib (LY2606368) is a selective, ATP-competitive second-generation checkpoint kinase 1 (CHK1) inhibitor with a K_i of 0.9 nM and an IC₅₀ of <1 nM. Prexasertib inhibits CHK2 (IC₅₀=8 nM) and RSK1 (IC₅₀=9 nM). Prexasertib causes double-stranded DNA breakage and replication catastrophe resulting in apoptosis. Prexasertib shows potent anti-tumor activity.

体外研究

Prexasertib (LY2606368) inhibits MELK (IC₅₀=38 nM), SIK (IC₅₀=42 nM), BRSK2 (IC₅₀=48 nM), ARK5 (IC₅₀=64 nM). LY2606368 requires CDC25A and CDK2 to cause DNA damage.
Prexasertib (33, 100 nM; for 7 hours) results in DNA damage during S-phase in HeLa cells.
Prexasertib (8-250 nM; pre-treated for 15 minutes) inhibits CHK1 autophosphorylation (S296) and CHK2 autophosphorylation (S516) in HT-29 cells.
Prexasertib (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.
Prexasertib (33 nM; for 12 hours) causes chromosomal fragmentation in HeLa cells. Prexasertib (100 nM; 0.5 to 9 hours) induces replication stress and depletes the pool of available RPA2 for binding to DNA.

Cell Cycle Analysis

Cell Line:	HeLa cells
Concentration:	33, 100 nM
Incubation Time:	For 7 hours
Result:	Had an IC₅₀ of 37 nM and resulted in the G2-M population received DNA damage during S-phase but continued to progress through the cell cycle into an early mitosis.

Western Blot Analysis

Cell Line:	HT-29 cells
Concentration:	8, 16, 31, 63, 125, 250 nM
Incubation Time:	Pre-treated for 15 minutes
Result:	Inhibited CHK1 autophosphorylation (S296) and CHK2 autophosphorylation (S516) (IC₅₀ of less than 31 nM) in HT-29 cells.

体内研究

Prexasertib (LY2606368; 1-10 mg/kg; SC; twice daily for 3 days, rest 4 days; for three cycles) causes growth inhibition in tumor xenografts.
Prexasertib (15 mg/kg; SC) causes CHK1 inhibition in the blood and the phosphorylation of both H2AX (S139) and RPA2 (S4/S8).

Animal Model:	Female CD-1 nu-/nu- mice (26-28 g) with Calu-6 cells
Dosage:	1, 3.3, or 10 mg/kg
Administration:	SC; twice daily for 3 days, rest 4 days; for three cycles
Result:	Caused statistically significant tumor growth inhibition (up to 72.3%).

Animal Model:	Female CD-1 nu-/nu- mice (26-28 g) with Calu-6 cells
Dosage:	15 mg/kg (Pharmacokinetic Analysis)
Administration:	SC (200 μL)
Result:	CHK1 was 7 ng/mL at 12 hours and 3 ng/mL by 24 hours in plasma exposures. Phosphorylation of both H2AX (S139) and RPA2 (S4/S8) was detectable at 4 hours, showing the rapid occurrence of DNA damage.
