Thalidomide 4-fluoride (E3 ligase Ligand 4) (Cereblon ligand 4) is the Thalidomide-based Cereblon ligand. Thalidomide 4-fluoride can be used in the recruitment of CRBN protein. Thalidomide 4-fluoride (Cereblon ligand 4) can be connected to the ligand for IRAK4 protein by a linker to form PROTAC IRAK4 degrader-1.

AU-15330 is a proteolytic targeting chimera (PROTAC) that simultaneously targets SMARCA4, SMARCA2, and PBRM1 for degradation and exhibits cytotoxicity in H3.3K27M cells but not in H3 wild-type cells. [2]

C004019 is a small molecule PROTAC capable of targeting tau for selective protein degradation from the cell, while recruiting tau and E3 ligase (Vhl) for selective enhancement of tau ubiquitination and proteollyzation. C004019 is a candidate for AD and related tau protein diseases.

CCT367766 is a potent, PROTAC-based, third-generation, iso-functional pirin-targeted protein degradation probe (PDP) that depletes pirin expression at low concentrations.CCT367766 has an IC50 value of 490 nM for the CRBN-DDB1 complex.CCT367766 has a good affinity for recombinant pirin and CRBN. CCT367766 has a good affinity for recombinant pirin and CRBN, with Kd values of 55 nM and 120 nM, respectively. cct367766 is a potent orally active protein that reduces the expression of pirin at low concentrations.

β-NF-JQ1 is a PROTAC that recruits aryl hydrocarbon receptor E3 (AhR E3) ligase to target proteins. Using β-NF as an AhR ligand, it targets bromodomain (BRD)-containing proteins and induces AhR and BRD protein interactions. β-NF-JQ1 exhibits potent anticancer activity associated with protein knockdown activity.

AS-2444697 is an inhibitor of IRAK-4 (C50 = 21 nM). AS-2444697 exhibits renoprotective effects through anti-inflammatory action. AS-2444697 potently inhibits human and rat IRAK-4 activity.

dBET1 is a hybrid molecule that combines (+)-JQ1 and thalidomide. It induces cereblon-dependent BET protein degradation in vitro (EC50: 430 nM) and induces apoptosis.

IRAK inhibitor 2 (IRAK-IN-2) is a potent inhibitor of interleukin 1 receptor-associated kinase 4 (IRAK-4) for the study of inflammation-related diseases.
