CK1 Degrader

DEG-77 is a molecular glue targeting IKZF2 and CK1α, with DC₅₀ values of 15.3 nM and 10 nM, respectively. DEG-77 exhibits significant anti-tumor activity, inducing increased transcriptional levels of the pro-apoptotic protein Bax and the cell cycle arrest protein p21. DEG-77 is applicable to the research of acute myeloid leukemia (AmL), diffuse large B-cell lymphoma and ovarian cancer.

MGD-28 is a potent, orally active, Cereblon (CRBN)-dependent IKAROS protein degrader that degrades IKZF1 (DC₅₀=3.8 nM), IKZF2 (DC₅₀=56.3 nM), and IKZF3 (DC₅₀=7.1 nM) in a dose-dependent manner. In addition, MGD-4 also degrades CK1α (DC₅₀=7.8 nM). MGD-28 has antiproliferative activity and can be used in multiple myeloma research.

WH-10417-099 is a CRBN-based PROTAC multi-kinase degrader that induces the degradation of the maximum number of unique kinases (over 125 unique kinases, such as CSNK1E and PI3Kγ) simultaneously. WH-10417-099 induces protein degradation via the ubiquitin biotinylation (E-STUB) pathway, exhibits synergistic effects with SB-405483 (HY-W1135319). The E3 ligase ligand and linker of WH-10417-099 can form the conjugate Pomalidomide 4'-PEG5-acid (HY-131647).

IBA-11 is a selective CRBN-dependented CK1α molecular glue degrader. IBA-11 binds to the canonical tri-tryptophan pocket of CRBN, forming a ternary complex with CK1α to mediate its degradation. IBA-11 induces CRBN-dependent ubiquitin-proteasome system-mediated degradation of CK1α. IBA-11 exhibits cytotoxicity against cancer cells. IBA-11 demonstrates in vitro metabolic stability in rat liver microsomes and minimal hERG inhibition. IBA-11 can be used for the research of cancer, such as acute myeloid leukemia.
