Berzosertib (VE-822) is an intravenous (i.v.), highly potent and selective inhibitor of ATR (IC50 =19nM) [1]. Under radiation, Berzosertib can activate both the canonical cGAS-STING-pTBK1/pIRF3 axis by increasing cytosolic double-stranded DNA levels and the non-canonical STING signaling by attenuating SHP1-mediated inhibition of the TRAF6-STING-p65 axis, via promoting SUMOylation of SHP1 at lysine 127 [2]. Berzosertib has been widely used to inhibit tumor progression and enhance the killing effect of radiation therapy on tumors[3].
In vitro, Berzosertib treatment for 72h significantly inhibited the viability of Cal-27 and FaDu cells with IC50 values of 0.285µM and 0.252µM, respectively[4]. Treatment with 80nM Berzosertib for 19 hours significantly reduced the phosphorylation level of Chk1 and decreased the survival of MiaPaCa-2 cells under 4Gy radiation[5]. Treatment with 6µM Berzosertib for 24 hours led to a significant increase in the levels of γ-H2AX, pp53, and cc3 in U2OS cells, accompanied by DNA breaks and cell apoptosis[6].
In vivo, Berzosertib treatment via a single oral dose of 60mg/kg for 48 hours led to the accumulation of DNA damage and a decrease in P-Chk1 expression within the tumors of mice bearing the OD26749 xenografts [7]. Administering 60mg/kg of Berzosertib orally 4 times per week for 3 weeks significantly inhibited tumor growth in H827-xenograft mice and upregulated the activity of OTUD1 protein[8].

| Cell experiment [1]: | |
|
Cell lines |
Cal-27 cells |
|
Preparation Method |
Cal-27 cells were grown in DMEM with 10% (v/v) fetal bovine serum (FBS), antibiotic/antimycotic solution at 37°C in 5% CO2/atmosphere. Cal-27 cells were cultured in growth medium in 96-well dishes at a density of 5000 cells per well. One day after seeding, cells were treated with Berzosertib (0.031, 0.063, 0.125, 0.25, and 0.5µM). After 72h of incubation, cell viability was measured. |
|
Reaction Conditions |
0.031, 0.063, 0.125, 0.25, and 0.5µM; 72h |
|
Applications |
Berzosertib treatment significantly inhibited the cell viability of Cal-27 cells in a dose-dependent manner. |
| Animal experiment [2]: | |
|
Animal models |
BALB/c nude mice |
|
Preparation Method |
Male BALB/c nude mice (4 weeks old) were housed singly in a standard environment with food and water ad libitum. H827 cells (5×106) were suspended in 200µl PBS and then injected subcutaneously into the left and right. Two weeks after tumors became measurable, mice were randomly divided into PBS-treatment and Berzosertib treatment groups. Berzosertib was administered at a dose of 60mg/kg in 5% DMSO + 45% PEG300 + 50% sterile PBS once per day for 4 consecutive days every week by oral gavage and lasted 3 weeks. Tumor volume was measured and tumor volume=0.5×length×width2. |
|
Dosage form |
60mg/kg; 4 times a week for 3 weeks; p.o. |
|
Applications |
Berzosertib treatment significantly inhibited tumor growth in the H827 xenograft mouse model. |
