DC67407	IKZF1-degrader-1	IKZF1-degrader-1 (Compound 9-B) is a highly potent molecular glue that achieves sub-nanomolar degradation of IKZF1 (DC50 = 0.134 nM), demonstrating significant therapeutic potential for targeting IKZF1-dependent malignancies.
DC67406	EM12-FS	EM12-FS is a bifunctional CRBN modulator that engages cereblon at His353 while functioning as a molecular glue to induce NTAQ1 degradation. Demonstrating favorable pharmacokinetics, it exhibits a human plasma half-life of 196 minutes, supporting its therapeutic potential.
DC67405	Acetyl-cyclosporin A aldehyde	Acetyl-cyclosporin A aldehyde is a chemically modified derivative of cyclosporin A (HY-B0579), featuring an acetyl group and a reactive aldehyde moiety. The parent compound, cyclosporin A, is a dual-function molecule that both inhibits calmodulin signaling and binds cyclophilin, thereby blocking NF-AT nuclear translocation and inducing mitochondrial dysfunction.
DC67404	QS-57	QS-57 is a bifunctional degrader that combines BRD4-targeting PROTAC activity with 14-3-3 molecular glue properties.
DC67403	KRAS ligand 4	KRAS ligand 4 (compound 2) is a SOS1-targeting bifunctional molecular glue that suppresses oncogenic signaling by degrading key KRAS pathway components, evidenced by reduced pERK and pS6 levels. It demonstrates broad-spectrum activity against diverse KRAS mutations, disrupting proliferation across resistant cancer models.
DC67402	Pomalidomide-15N,13C5	Pomalidomide-15N,13C5 is a stable isotope-labeled variant of pomalidomide (HY-10984), a third-generation immunomodulatory drug that functions as a cereblon-directed molecular glue. This compound mediates targeted ubiquitination and degradation of Ikaros family transcription factors (IKZF1/3) through recruitment of the CRL4CRBN E3 ligase complex, underpinning its therapeutic mechanism.
