Mezigdomide (CC-92480) is a potent, novel, selective and active cereblon E3 ubiquitin ligase modulator (CELMoD) that acts as a molecular glue. Mezigdomide has anti-myeloma activity. [1]

NSC-697923 (2-[(4-methylphenyl)sulfonyl]-5-nitrofuran), a potent inhibitor of UBE2N (ubiquitin-conjugating enzyme E2 N, Ubc13), exhibits its role in inducing cell death in neuroblastoma (NB) cells through two distinct mechanisms. In p53 wild-type NB cells, NSC-697923 promotes the nuclear importation of p53, thereby triggering cell death. Meanwhile, in p53 mutant NB cells, NSC-697923 activates the JNK-mediated apoptotic pathway, leading to cell death. Additionally, NSC-697923 inhibits DNA damage and NF-κB signaling, further contributing to its antitumor activity.

alphaSYN-IN-NAB2, a neuron-protective agent, is a protein encoded by the NAB2 gene. NAB2 effectively and selectively protects a variety of cells from alpha-SYN toxicity. NAB2 promotes endosomal transport dependent on E3 ubiquitin ligase Rsp5 Nedd4.

NAB2 is involved in cellular processes such as cell differentiation, apoptosis and stress response, and can be used to study cancer, neurodevelopment and neuronal activity.
