NF-κB Degrader

EN450 is a cysteine-reactive covalent molecular glue degrader targeting NF-κB. EN450 interacts with allosteric C111 in the E2 ubiquitin ligase UBE2D. EN450 induces the ternary complex formation between UBE2D and NFKB1. EN450 exerts its anti-proliferative effects through a Cullin E3 ligase and proteasome-dependent mechanism.

NF-κB degrader 1 (Compound MD-1) is a NF-κB1 p105 subunit degrader. NF-κB degrader 1 shows anti-inflammatory activity (IC₅₀ for inhibiting TNF-α is 2.02 μM, and for inhibiting NO is 5.40 μM). NF-κB degrader 1 induces p105 degradation dependent on the Cullin-RING ligase (CRL) SCFBTCP, suppressing NF-κB transcriptional activity. NF-κB degrader 1 is promising for research of inflammation-related diseases.

Dth (DFHBI-thalidomide) is an RNA aptamer-based PROTAC degrader. Dth can degrade a variety of endogenous proteins (such as mCherry, p50, p65 and E2F1) by replacing the 3′ module on the RNA scaffold with the RNA aptamer corresponding to the target protein. Dth upregulates IκB-α and Bax, and downregulates Bcl-2 and VEGF. Dth generates green fluorescence upon binding to the Broccoli RNA aptamer, enabling the tracing of RNA scaffolds. Dth can be used in cancer-related research.
