Description

ALV2 is a potent and selective Helios molecular glue degrader. ALV2 binds CRBN, with an IC50 of 0.57 μM. Helios is the zinc-finger transcription factor that can maintain a stable Treg cell phenotype in the inflammatory tumor microenvironment[1].

IC50 & Target

IC50: 0.57 μM (CRBN)[1]
In Vitro

ALV2 (10 nM-100 μM) induces CRBN-Helios dimerization in the TR-FRET assay[1].
ALV2 (0.1-10 μM) preferentially promotes Helios degradation in Jurkat cells[1].
ALV2 (1 μM; pretreated for 18 h) promotes IL-2 secretion in Jurkat cells[1].

In Vivo:

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.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: 4 mg/mL (7.63 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 4 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (40.0 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.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: 4 mg/mL (7.63 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 4 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (40.0 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.
