(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 BET PROTAC degrader relying on von Hippel-Landau (VHL) E3ligase, 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.
E3ligaseLigand 10 serves as a ligand for E3 ubiquitin ligase and can be conjugated to a protein ligand through a linker, resulting in the formation of PROTACs. These PROTACs act as inducers of ubiquitination-mediated degradation, specifically targeting cancer-promoting proteins[1].
E3ligaseLigand 13 is an E3 ubiquitin ligaseligand that can be employed to create PROTACs, which are connected to the ligand for the protein through a linker. PROTACs serve as inducers of ubiquitination-mediated degradation of cancer-promoting proteins[1].
E3ligaseLigand 14 is a ligand that binds to E3 ubiquitin ligase and can be conjugated to a protein ligand via a linker to create PROTACs. These PROTACs are capable of promoting ubiquitination-mediated degradation of cancer-promoting proteins[1].
E3ligaseLigand 18 is a ligand that binds to E3 ubiquitin ligase, and it can be chemically attached to a protein ligand through a linker to create PROTACs. The resulting PROTACs function as inducers of ubiquitination-mediated degradation, targeting cancer-promoting proteins[1].
PROTAC Sirt2 Degrader-1 is a SirReal-based PROTAC, 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. PROTAC Sirt2 Degrader-1 shows an IC50 of 0.25 μM for Sirt2, with no effect on Sirt1 Sirt3 (IC50s > 100 μM)[1].
