RP-2119
Based on 1 Customer Validation
RP-2119 is an orally bioactive Polymerase Theta (Polθ) inhibitor, with an IC50 of 0.7 nM against human Polθ ATPase. RP-2119 reduces Polθ activity and exerts antiproliferative effects in BRCA2-deficient cancer cells. RP-2119 exhibits antitumor activity in BRCA2-deficient cancer cell xenograft mouse models. RP-2119 can be used for the research of cancer and homologous recombination-deficient cancers, including brca1/brca2-mutant cancers and shld2-mutant cancers.

Biological Activity
RP-2119 potently inhibits human Polθ ATPase activity in the ADP-Glo biochemical assay, with an IC50 of 0.7 nM. It also inhibits Polθ ATPase activity in mice, rats, dogs, pigs and chimpanzees, with IC50 values ranging from <1.5 nM to <5 nM in the ADP-Glo biochemical assay[2].
RP-2119 binds to Polθ in K562 cells expressing the ePL-tagged Flag-Polθ helicase domain, with an EC50 of 82 nM in the CETSA assay[2].
RP-2119 (for 12-14 days) potently inhibits the proliferation of DLD-1, HCT 116 and DOTC24510 BRCA2-/- cells, with EC50 values of 45, 51 and 266 nM[2].
RP-2119 inhibits Polθ-mediated MMEJ activity in DLD-1 cells carrying Cas9/sgRNA-induced double-strand breaks at the AAVS1 locus, with an IC50 of 54 nM[2].

RP-2119 (45 mg/kg; p.o.; once daily; for the entire study duration) enhances the tumor volume reduction effect of Carboplatin (HY-17393) in a mouse DLD1 BRCA2-/- colorectal cancer model[1][2].
Combination treatment with RP-2119 (45 mg/kg; p.o.; twice daily; up to 50 days) and Olaparib induces tumor regression in the BRCA2-mutant mouse HBCx-10 breast cancer PDX model, with significantly enhanced efficacy compared to Olaparib monotherapy[2].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (4.93 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (4.93 mM); Suspended solution
This protocol yields a suspended solution of ≥ 2.5 mg/mL (saturation unknown). Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
