Biological Activity
Ceralasertib is an orally available inhibitor of ataxia telangiectasia and rad3 related (ATR) kinase. Ceralasertib selectively inhibits ATR activity by blocking the downstream phosphorylation of the serine/threonine protein kinase CHK1. This prevents ATR-mediated signaling, and results in the inhibition of DNA damage checkpoint activation, disruption of DNA damage repair, and the induction of tumor cell apoptosis.
Safety & Regulatory
For Research Use Only (RUO). Not for therapeutic, diagnostic, or clinical use. Wear appropriate PPE and consult the Safety Data Sheet (SDS) prior to handling.
It is not recommended to store DMSO stock solutions at room temperature. Once the stock solution is prepared, aliquot into single-use volumes and store at −20 °C (or −80 °C for sensitive compounds). Room-temperature storage accelerates chemical degradation and moisture uptake. When ready to use, thaw an aliquot at room temperature, use immediately, and avoid repeated freeze-thaw cycles.
Stock concentration (mM) = [mass (mg) × 1000] / [MW (g/mol) × volume (mL)]. Example: to prepare 10 mM stock from 5 mg of a 500 g/mol compound: volume = (5 × 1000) / (500 × 10) = 1 mL DMSO. For working solutions, dilute the DMSO stock into assay buffer: C₁V₁ = C₂V₂. For a 1 µM working solution from a 10 mM stock in a 1 mL assay volume, add 0.1 µL of stock (or pre-dilute to an intermediate concentration first).
