LY 2606368 Chemical Properties, Uses, Production
Description
LY2606368 is a checkpoint kinase 1 (Chk1) inhibitor with a Ki value of 0.9 nM against the purified target and IC50 values of <13 nM in a viability study of multiple colorectal cancer cell lines. Inhibition of Chk1 causes double-strand DNA breakage in cells leading to an excessive cell damage burden and subsequent cell death. In vitro, LY2606368 inhibits the doxorubicin-activated G2/M checkpoint in p53-deficient HeLa cells with an EC50 value of 9 nM. LY2606368, at 25 nM, also significantly induces apoptosis and inhibits colony formation in AGS and MKN1 gastric cancer cells.
Uses
LY 2606368 is a novel CHK1 inhibitor under investigation as a chemopotentiating agent. It causes double-stranded DNA breakage while simultaneously removing the protection of the DNA damage checkpoints. LY 2606368 is representative of a novel class of drugs for the treatment of cancer and tumor growth inhibition.
in vivo
Prexasertib (LY2606368; 1-10 mg/kg; SC; twice daily for 3 days, rest 4 days; for three cycles) causes growth inhibition in tumor xenografts[1].
Prexasertib (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] |
| 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[1] |
| 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. |
IC 50
Chk1: 0.9 nM (Ki); Chk1: <1 nM (IC50); Chk2: 8 nM (IC50)
