SJ988497
Based on 1 Customer Validation
SJ988497 is a PROTAC degrader targeting JAK2. SJ988497 induces the proteasomal degradation of CRBN-mediated JAK2, JAK1, JAK3, GSPT1, and IKZF1, and functions as a CRBN neosubstrate for GSPT1. SJ988497 retains binding affinity for the kinase domain of JAK2. SJ988497 can be used in studies related to cancers such as crlf2-rearranged acute lymphoblastic leukemia.
(Pink: JAK2 ligand (HY-184994); Blue: Cereblon ligand (HY-41547); Black: linker).

In Vitro
SJ988497 (72 h) potently reduces viability of multiple acute lymphoblastic leukemia cell lines in a CRBN-dependent manner, with an EC50 of 0.4 nM in CRLF2-rearranged MHH-CALL-4 parental ALL cells[1].
SJ988497 (compound 7) mediates target protein degradation in MHH-CALL-4 human acute lymphoblastic leukemia cells[2].
SJ988497 degrades its target protein, suppresses JAK-STAT pathway signaling, and induces cytotoxicity in MHH-CALL-4 human acute lymphoblastic leukemia cells[2].
SJ988497 produces cytotoxicity and mediates target protein degradation in ex vivo cultured MHH-CALL-4 human acute lymphoblastic leukemia cells[2].
SJ988497 demonstrates high cellular permeability in the Caco-2 assay, consistent with its optimized low molecular weight and reduced polar surface area that improves cellular uptake[1].
SJ988497 maintains high binding affinity for the JAK2 target with a distribution coefficient of 0.3 nM, comparable to the affinity of its parent JAK inhibitor scaffold[1].
SJ988497 (1 h) achieves equivalent JAK signaling inhibition levels as the parent JAK inhibitor Ruxolitinib (HY-50856) in TSLP-stimulated MHH-CALL-4 cells[1].

- 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 (3.63 mM); Clear solution; Need ultrasonic
This protocol yields a clear solution of 2.5 mg/mL.
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.
