PLX-4545
Based on 1 Customer Validation
PLX-4545 is an orally active, selective molecular glue degrader targeting IKZF2. Through a molecular glue mechanism, PLX-4545 binds to CRBN, recruits IKZF2 to form a ternary complex, and promotes its ubiquitination and proteasomal degradation. This further converts inhibitory regulatory T cells (Treg) into effector-like T cells, enhances CD8+ T cell responses, and modulates the Teff:Treg balance. PLX-4545 also increases the production of the inflammatory cytokine IL-2 and reduces the suppressive activity of Treg. PLX-4545 can be used in cancer immunotherapy research, and exhibits a synergistic effect when combined with immune checkpoint inhibitors such as anti-PD1.

PLX-4545 rapidly and completely degrades IKZF2, reduces the expression of CD25 and FOXP3 in inhibitory regulatory T cells (Treg), converts them into effector-like T cells, and simultaneously promotes the proliferation of effector T cells (Teff)[1].
PLX-4545 promotes the production of inflammatory cytokines IL-2 and IFNγ, enhances CD8+ T cell responses, regulates the Teff:Treg balance, and exerts a selective degradation effect on IKZF2[1].

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 (5.28 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 (5.28 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 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
