thalidomide 4 fluoride

Thalidomide 4-fluoride (E3 ligase Ligand 4) (Cereblon ligand 4) is the Thalidomide-based Cereblon ligand. Thalidomide 4-fluoride can be used in the recruitment of CRBN protein. Thalidomide 4-fluoride (Cereblon ligand 4) can be connected to the ligand for IRAK4 protein by a linker to form PROTAC IRAK4 degrader-1.

XYD049 (compound 7d) is a CRBN-type molecular glue targeting GSPT1, with a DC50 of 19 nM, used for researching MYC-driven castration-resistant prostate cancer (CRPC). It effectively inhibits the growth of 22Rv1 cells (IC50 = 7 nM) and exhibits antitumor efficacy in vivo. XYD049 downregulates CRPC-associated oncogenes in 22Rv1 cells, including AR, AR-v7, PSA, and c-Myc. XYD049 comprises a molecular glue linker (black part) NH2-C5-NH-Boc, a CRBN-type E3 ligase ligand (blue part) Thalidomide 4-fluoride, and a target protein ligand (red part) GSPT1 ligand-1, with the E3 ligase ligand + linker forming the conjugate E3 Ligase Ligand-linker Conjugate 158.

PROTAC CARM1/IKZF3 degrader-1 (Compound 074) inhibits CARM1, reducing the methylation level of its substrate BAF155. This PROTAC degrader works by degrading IKZF 1/3 via a CRBN-dependent mechanism. It suppresses MYC protein expression, thereby inhibiting the proliferation of various multiple myeloma cells. Additionally, PROTAC CARM1/IKZF3 degrader-1 can induce apoptosis in H929 cells and overcomes resistance to immunomodulatory drugs (IMiDs, such as pomalidomide). It is applicable for cancer and immunology research.

PT-129 is a PROTAC degrader targeting the NTF2 domain of G3BP1/2, capable of inhibiting and degrading stress granules in stressed cells, disrupting ATF4 trafficking, and suppressing fibroblast-mediated cancer cell proliferation.
