Mechanism of Action

Features	The first ATR-targeted drug candidate with high selectivity for ATR.
Targets/IC₅₀/Ki	ATR (HT29 cells) 19 nM
In vitro	Berzosertib (VE-822) at 80 nM attenuates the ATR signaling pathway and reduces survival in tumor cells in response to XRT and LY-188011. It also attenuates ATR signaling in normal cells without enhancing radiation and LY-188011 killing in such cells. This compound increases XRT-induced residual γH2AX and 53BP1 foci compared with XRT in MiaPaCa-2 and PSN-1 cells. Its pre-treatment decreases Rad51 foci after XRT in MiaPaCa-2 and PSN-1 cells. It alone increases the G1-phase-fraction in MiaPaCa-2 and PSN-1 cells, and abrogates XRT enriched G2/M-phase-fraction in these cells. VE-822 has little effect alone, while combined with XRT and/or LY-188011 it enhances early and late apoptosis in PSN-1 cells that is strongest in the triple combination. It increases tumor response to DNA damaging agents associated with blockade of pChk1 Ser345.
In vivo	Berzosertib (VE-822) at 60 mg/kg inhibits phospho-Ser-345-Chk1 in mice bearing PSN-1 tumors after DNA-damaging agents. Combined with XTR, it doubles the time for tumors to grow to 600 mm³ compared with XRT alone in mice bearing both PSN-1 and MiaPaCa-2 tumors. When added to the combination of LY-188011 and XRT, this compound substantially prolongs tumor growth delay compared with the Gem+XRT1 group in mice bearing PSN-1 tumors. Its combination with XRT1 increases uptake in tumors by 44% compared with XRT1, suggesting that addition of VE-822 increased γH2AX phosphorylation and persistence of DNA damage caused by XRT.
