PROTACBETDegrader-10 (WO2017007612A1, example 37) is a highly efficient and selective small molecule compound designed to degrade BET protein BRD4. PROTACBETDegrader-10 functions by utilizing specific ligands that connect Cereblon and BRD4, with a DC 50 value of 49 nM.
(S,R,S)-AHPC-Me dihydrochloride, also known as VHL ligand 2 dihydrochloride, is a chemical compound utilized in the synthesis of ARV-771. ARV-771, a BETPROTACdegrader relying on von Hippel-Landau (VHL) E3 ligase, demonstrates potent degradation of BET protein in castration-resistant prostate cancer (CRPC) cells, with a DC50 of less than 1 nM. This compound serves as the VHL ligand, specifically the (S,R,S)-AHPC-based VHL ligand, that facilitates the recruitment of von Hippel-Lindau (VHL) protein.
PROTAC BRD2 BRD4 degrader-1 (compound 15) serves as a potent, selective degrader of BET proteins BRD4 and BRD2, achieving rapid, reversible, and unexpectedly selective elimination of BRD4 and BRD2 compared to BRD3. Its efficacy in suppressing solid tumors manifest with minimal cytotoxic effects. This compound comprises a BET inhibitor, a connecting linker, and thalidomide as the ligand for cereblon (CRBN) cullin 4A[1].
PROTAC BRD4 degrader for PAC-1 (compound 5) is a chimeric BETdegrader GNE-987 conjugated with a disulfide-containing linker[1]. This PROTAC-linker conjugate specifically targets and degrades BRD4, enabling selective proteolysis of PAC-1.
Thalidomide-NH-C4-NH2 TFA (compound 29c) is a conjugate consisting of an E3 ligase ligand-linker, incorporating the Thalidomide-based cereblon ligand and a linker moiety. This compound, Thalidomide-NH-C4-NH2 TFA, is utilized as a component in PROTAC BRD2 BRD4 degrader-1, which is a highly potent and selective degrader targeting BET proteins BRD4 and BRD2[1].
