IBR2

Catalog No. T11600Cas No. 313526-24-8

IBR2 (Isoquinoline) is a potent and specific RAD51 inhibitor known for its ability to suppress RAD51-mediated DNA double-strand break repair. By interfering with RAD51 multimerization, accelerating proteasome-mediated RAD51 protein degradation, inhibiting cancer cell growth, and inducing apoptosis, IBR2 has proved to be an effective compound in these aspects.

Product Introduction

Bioactivity

Description	IBR2 (Isoquinoline) is a potent and specific RAD51 inhibitor known for its ability to suppress RAD51-mediated DNA double-strand break repair. By interfering with RAD51 multimerization, accelerating proteasome-mediated RAD51 protein degradation, inhibiting cancer cell growth, and inducing apoptosis, IBR2 has proved to be an effective compound in these aspects.
In vitro	IBR2 can inhibit the growth of triple-negative human breast cancer cell line MBA-MD-468 with IC50 of 14.8 μM. IBR2 shows interesting RAD51 inhibition activities. RAD51 is rapidly degraded in IBR2-treated cancer cells, and the homologous recombination repair is impaired, subsequently leading to cell death. The IC50 values of the original IBR2 are in the range of 12-20 μM for most tested cancer cell lines[1].
Alias	Isoquinoline

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:

For example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments

A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent

DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。

Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSO TargetMol | reagent

(mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.

Preparation method for in vivo formula: Take 50 μL DMSO TargetMol | reagent

main solution, add 300 μLPEG300 TargetMol | reagent

mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2O TargetMol | reagent

mix well and clarify
