DIM-3,5-Cl2

Customer Review

Based on 1 Customer Validation

DIM-3,5-Cl2 is an inverse NR4A1/NR4A2 agonist with K_D values of 7.7 μM and 12.0 μM for NR4A1 and NR4A2, respectively. DIM-3,5-Cl2 acts as an inverse agonist to downregulate pro-oncogenic and proendometriotic gene products, and as an agonist to enhance NR4A1/2/Sp1/Sp4-mediated CD71 transactivation. DIM-3,5-Cl2 induces ferroptosis via ROS formation, lipoperoxidation, MDA production, and reduced GPX4, SLC7A11 expression. DIM-3,5-Cl2 induces apoptosis via PARP and caspase-3 cleavage, reduced BCL-2 expression, and inhibits cancer cell viability. DIM-3,5-Cl2 can be used for the research of triple negative breast cancer, endometriosis, and colorectal cancer.

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.

Protocol 1

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 2.5 mg/mL (6.39 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
