Nrf2 degrader 30 is a small molecule PROTAC that inhibits the degradation of Nrf2, thereby enhancing its activity. Nrf2 is a key transcription factor that regulates cellular antioxidant responses and various protective mechanisms. The activity of Nrf2 is primarily regulated by its interaction with Keap1, which serves as an E3 ubiquitin ligase complex adapter to promote Nrf2 ubiquitination and proteasomal degradation。

BMS-986449 is a CELMoD-type molecular gel that remodels the function of regulatory T cells (Treg) and enhances their anti-tumor immune responses by directing the E3 ubiquitin ligase, Cereblon, to target the degradation of IKZF2 (Helios) and IKZF4 (Eos). BMS-986449 has potential application in the study of advanced solid tumors.

Navitoclax-piperazine (ABT-263-piperazine) is a B-cell lymphoma extra large (BCL-XL) inhibitor.

E3 ligase Ligand 8, a ligand for E3 ubiquitin ligase, can be connected to protein ligands through linkers to form PROTACs, which induce ubiquitination-mediated degradation of cancer-promoting proteins.

ARV-393 is a PROTAC degrader targeting BCL6 with the advantage of being highly potent and orally available.ARV-393 recruits BCL6 and E3 ligase cerebellum to rapidly degrade BCL6 through the cell's natural ubiquitin proteasome system for the treatment of diffuse large b-cell lymphoma (DLBCL) and non-Hodgkin's lymphoma (NHL).

FKBP12 PROTAC dTAG-13 is a PROTAC and selective degrader that can be used for target validation during drug discovery by splicing FKBP12 F36V with CRBN and thereby degrading FKBP12 F36V.

PROTAC Mcl1 degrader-1 is a Cereblon ligand-based targeted chimeric protein degrader (PROTAC), a selective Mcl-1 inhibitor. By hijacking the CRBN ubiquitin ligase to form a ternary complex with the target protein, it induces Mcl-1 ubiquitination. It can be used for cancer research.

SIAIS178 is a selective PROTAC degrader targeting BCR-ABL with an IC50 of 24 nM. It degrades BCR-ABL protein by recruiting the VHL E3 ubiquitin ligase, inhibiting leukaemia cell growth in vitro and causing regression of K562 xenograft tumours.

MAK683-CH2CH2COOH binds to EED (embryonic ectoderm development protein) and, together with a VHL ligand for the E3 ubiquitin ligase, has been used to design EED-Targeted PROTACs, specifically EED degrader-1 and PROTAC EED degrader-2 [1].

Boc-NH-PEG2-C2-NH2 (PROTAC Linker 13) is a PEG-based linker used in PROTAC synthesis, essential for connecting the targeted protein and the E3 ubiquitin ligase to facilitate selective protein degradation[1].

PROTAC Sirt2 Degrader-1 is a SirReal-based PROTAC that acts as a Sirt2 degrader, composed of a highly potent and isotype-selective Sirt2 inhibitor, a linker, and a bona fide cereblon ligand for E3 ubiquitin ligase.
