MI-773 (SAR405838 (MI 773)) is an orally available MDM2 antagonist with Ki of 0.88 nM. Phase 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.

SPOP-IN-6lc is a potent SPOP inhibitor with multiple roles in cancer, oncostatic in a variety of tumors, but functions as an oncogene in renal cancer.SPOP-IN-6lc can be used to study cell signaling and apoptosis.

Indole-3-carbinol (I3C), a naturally occurring, orally available cleavage product of the glucosinolate glucobrassicanin, inhibits NF-κB and IκBα kinase activation.

HOIPIN-8 is a potent inhibitor of the linear ubiquitin chain assembly complex (LUBAC) with an IC50 of 11 nM. As a derivative of HOIPIN-1, it exhibits 255-fold greater inhibition of both petit-LUBAC and TNF-α-mediated NF-κB activation compared to HOIPIN-1. HOIPIN-8 is a promising tool to explore cellular functions of LUBAC.
