BSJ-03-204
Based on 1 Customer Validation
BSJ-03-204 is a PROTAC-based CDK degrader derived from Palbociclib (HY-50767). BSJ-03-204 targets bovine CDK4/CCND1 and CDK6/CCND1 complexes with IC50 values of 26.9 nM and 10.4 nM, respectively. BSJ-03-204 also triggers ubiquitination and degradation of RB1, reduces pRb levels, thereby inducing G1 cell cycle arrest and exerting antiproliferative effects, as well as inducing time-dependent KLHL8 accumulation. BSJ-03-204 can be used in research related to pancreatic ductal adenocarcinoma, breast cancer, lung cancer, mantle cell lymphoma, and cloned bovine placental hyperplasia.

MCE Validation Data
In Vitro
BSJ-03-204 (0.02-20 μM; 15 min) directly binds to and stabilizes CDK4, CDK6, CRBN, CSNK2A2, FECH, HNRNPDL, HNRNPUL1, PIP4K2A, PLK1, TIA1 and TIAL1 in lysed K562 cells, while destabilizing RB1, with EC50 values ranging from 0.3 μM to 10.0 μM[1].
BSJ-03-204 (0.02-20 μM; 1 h) induces degradation of CDK4 and CDK6 at lower concentrations and stabilizes them at 20 μM in intact K562 cells. It also stabilizes CRBN, FECH, HNRNPDL, HNRNPUL1, PIP4K2A, PLK1, TIA1 and TIAL1, and destabilizes RB1, with EC50 values ranging from 1.1 μM to 14.4 μM[1].
BSJ-03-204 (0.1-0.2 μM; 18-48 h) mediates the degradation of CDK4 and CDK6 in 1222 pancreatic ductal adenocarcinoma (PDAC) cells; at 18 h, it exhibits stronger activity against CDK4 than Palbo-PROTAC, while at 48 h, its degradative effect persists but is less potent than that of BSJ-02-162[2].
BSJ-03-204 (250 nM; 5 h) selectively degrades CDK4 and CDK6 in Molt4 cells, with no degradation of IKZF1 or IKZF3 observed[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

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.
